Open Company Data in Sierra Leone: Official Sources, APIs and Reuse Rights

Sierra Leone is a workable official-source jurisdiction for company-data verification, but it should not be presented as a simple open-bulk register. The clean path starts with the OARG company-search route, then uses National Investment Board registration guidance, SLIEPA investor guidance, NPPA procurement data, National Revenue Authority tax guidance, legal-publication sources, SLICOM insurance-regulator context, ARIPO IP context and GLEIF LEI records.

The old CompaniesData Sierra Leone article was too thin for the current editorial bar and relied too heavily on routes that did not pass strict live QA. This refresh keeps OARG’s root, OARG business-register route, OARG IP route and Bank of Sierra Leone as source-risk findings, while using only links that returned real content to browser, Googlebot and Bingbot profiles.

Key Takeaways

• Best starting point: use the OARG company-search route as the practical public registry workflow layer.
• Registration context: NIB and SLIEPA explain business-registration and investor-service workflows, but they are not company master databases.
• Strong enrichment layers: NPPA bids/awards, NRA TIN guidance, OAGMOJ/SierraLII legal materials, SLICOM and GLEIF add context after registry matching.
• No bulk claim: this cycle did not verify a complete free official company-register bulk file or public API for every Sierra Leone company.
• Held sources: Statistics Sierra Leone, Stats SL economic statistics, OARG homepage, OARG business register, OARG intellectual property register, Bank of Sierra Leone remain research-only because they returned server errors, blank bot semantics or unstable content.
• Contact-data caution: registry, tax, procurement, regulator and legal-publication sources do not create consent for business emails, phone lists or sales-prospecting lists. International contact-data work should route through CompaniesData.cloud.

Editorial Methodology

This refresh follows the CompaniesData open-company-data standard: official sources first, claims scoped to each source’s actual content, and no publication link when a route fails live source QA. Every source was checked on 13 June 2026 with browser, Googlebot and Bingbot user agents. Sources that returned HTTP 500, blank bot semantics or unstable legal/source behavior were held out of the public link set even when the source looked relevant by name.

The source classification separates registry workflow, registration guidance, tax, procurement, statistics, legal publication, IP, sector regulation and LEI data. OARG company search is the primary registry workflow source. NIB and SLIEPA are procedural support. NRA and NPPA are purpose-limited enrichment layers. OAGMOJ, SierraLII and WIPO Lex provide legal basis and gazette context. ARIPO and SLICOM add specialist IP and insurance-regulator context. GLEIF is the only clean API layer verified in this cycle.

• Included: OARG company search, NIB, NIB business-registration portal, NIB business portal, SLIEPA starting-a-business guidance, NPPA, NRA, SLICOM, OAGMOJ gazettes, SierraLII, WIPO Lex, ARIPO and GLEIF.
• Held back: OARG root, OARG business-register route, OARG IP route, Stats SL pages and Bank of Sierra Leone were not linked from the article because live QA found source-risk blockers.
• Access date: source checks and crawler-profile evidence are dated 13 June 2026.

Coverage, Access and Update-Risk Analysis

The strongest coverage layer is still the OARG company-search route, but this refresh avoids pretending that every OARG path is stable. The company-search route passed across profiles; the OARG root and business-register path returned server errors. NIB and SLIEPA help users understand the business-registration process, especially the move toward online registration, but they should be treated as workflow evidence rather than a company population dataset.

Procurement and tax sources widen the coverage view. NPPA bids and contract awards can identify supplier activity after a legal-name match. NRA TIN pages explain taxpayer identifiers and online TIN application workflows for businesses. Statistics Sierra Leone would be valuable for aggregate economic and business-environment context, but the Stats SL routes are held in this cycle because they triggered the strict final soft-block marker check. These layers are useful for enrichment and coverage modelling, but none of them replaces the registry workflow.

Legal and specialist sources matter because Sierra Leone’s company-data interpretation depends on law and public notices. OAGMOJ gazettes, SierraLII and WIPO Lex help document the Companies Act and legal-publication context. ARIPO and SLICOM add IP and insurance-sector context. GLEIF offers a stable API for the subset of entities with LEIs. The Bank of Sierra Leone route should be revisited later because browser content is visible, but bot profiles received blank semantics in this cycle.

Reuse Checklist

• OARG search: use as manual verification and registry-workflow evidence; do not describe it as a complete bulk database.
• NIB and SLIEPA: cite as registration guidance and process context, not entity-level data exports.
• NRA TIN information: treat taxpayer identifiers as compliance-sensitive and purpose-limited.
• NPPA procurement: use for supplier/activity enrichment only after name matching; procurement data is not incorporation status.
• Statistics: keep direct Stats SL routes in source-risk review until the soft-block marker issue is cleared; aggregate statistics are not individual company records.
• Legal materials: use OAGMOJ, SierraLII and WIPO Lex to support legal-basis claims and update-risk notes.
• GLEIF: use the API for LEI-bearing entities and mark coverage as partial.
• Private contact data: business emails, phone lists and lead lists require a separate lawful-use workflow through CompaniesData.cloud.
• No endorsement: do not imply that Sierra Leone authorities endorse a normalized commercial dataset.

Source-by-Source Deep Dives

OARG company search

Authority and coverage: Office of the Administrator and Registrar General is classified as a registry layer. It contributes search route, OARG provenance, legal-name lookup context and manual verification workflow. The safe claim is narrow: Primary public route for checking Sierra Leone company-search workflow evidence.

Access model and reuse: The live route is public OARG company-search route. Reuse should follow OARG search-route terms and fair official-source citation; no bulk reuse licence verified. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use this as the first registry provenance anchor, then attach NIB, tax, procurement, legal, regulator and LEI evidence separately. Search workflow only; not a complete downloadable register or API. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: The company-search route is stable, while other OARG routes returned HTTP 500 in this cycle.

National Investment Board

Authority and coverage: National Investment Board of Sierra Leone is classified as a procedure layer. It contributes investment-board provenance, business-service navigation and official registration context. The safe claim is narrow: Government business-services context around registration, forms and investor facilitation.

Access model and reuse: The live route is public investment and business-services portal. Reuse should follow NIB site terms and official-source attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use NIB as workflow context around the registry rather than as the source of legal identity. Business-support portal rather than a company master dataset. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: NIB service pages can be reorganized as online business registration changes.

NIB online business registration

Authority and coverage: National Investment Board business registration portal is classified as a procedure layer. It contributes business-registration process, online account route, payment step and registration workflow. The safe claim is narrow: Explains the online registration process and current business-registration steps.

Access model and reuse: The live route is public online business registration guidance page. Reuse should follow NIB procedure-page attribution; no entity bulk grant. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use to document how entities enter the registration workflow and where manual evidence may be needed. Procedure page, not a register export. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Online registration steps can change with new portal releases.

NIB business portal

Authority and coverage: National Investment Board business portal is classified as a procedure layer. It contributes business portal, forms, registration resources and service navigation. The safe claim is narrow: Practical route for official forms, registration resources and business services.

Access model and reuse: The live route is public business portal. Reuse should follow NIB publication terms and attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as a procedural source and keep record-level claims tied to OARG or documented evidence. Navigation and resources, not an entity-level dataset. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Portal labels and paths can move as NIB services mature.

SLIEPA starting a business

Authority and coverage: Sierra Leone Investment and Export Promotion Agency is classified as a procedure layer. It contributes starting-a-business process, certificate guidance, corporate-affairs context and investor service notes. The safe claim is narrow: Legacy investor guidance that explains registration steps and Corporate Affairs/CAC context.

Access model and reuse: The live route is public investor guidance page. Reuse should follow SLIEPA publication terms and citation. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as a secondary workflow explainer and prefer OARG/NIB for current route claims. Guidance page; may lag current OARG/NIB portal operations. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: SLIEPA has been reorganized under the NIB transition; validate dates before operational use.

National Public Procurement Authority

Authority and coverage: National Public Procurement Authority is classified as a procurement layer. It contributes procurement authority provenance, tender/award navigation and public-procurement context. The safe claim is narrow: Official public procurement layer for tenders, awards and supplier activity context.

Access model and reuse: The live route is public procurement authority portal. Reuse should follow procurement-publication rules and NPPA site terms. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Match supplier names to OARG candidates with confidence scoring and keep procurement events separate. Procurement participation is a subset of companies and does not prove incorporation status. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Tender and award pages update frequently and should be timestamped.

NPPA bids

Authority and coverage: National Public Procurement Authority bids route is classified as a procurement layer. It contributes bid notices, procuring entities, dates and tender descriptions. The safe claim is narrow: Tender notices and bidder activity context for already-resolved entities.

Access model and reuse: The live route is public bids/tenders page. Reuse should follow notice-specific procurement terms and attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Store as procurement events with source URL and event date, then resolve names to companies separately. Tender notices are activity signals, not company identity master data. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Notice pages can roll over as deadlines pass.

NPPA contract awards

Authority and coverage: National Public Procurement Authority contract awards route is classified as a procurement layer. It contributes contract-award route, awarded supplier names where published, procuring entity and award context. The safe claim is narrow: Contract-award evidence for supplier/activity enrichment.

Access model and reuse: The live route is public contract-awards page. Reuse should follow award-publication terms and attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use awards as source-backed activity events attached to a separate legal entity. Awards are not universal company coverage and may need manual name resolution. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Award publications can be delayed or removed after procurement cycles.

National Revenue Authority

Authority and coverage: National Revenue Authority is classified as a tax layer. It contributes NRA provenance, tax-service context, domestic tax and taxpayer-service notes. The safe claim is narrow: Official tax authority context for domestic taxes, customs and taxpayer workflows.

Access model and reuse: The live route is public tax authority portal; TLS fallback may be required from this node. Reuse should follow tax confidentiality, NRA terms and purpose-limited use. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list. The live check needed an SSL-unverified retry from this node, so the source should keep a TLS monitoring flag in production QA.

Normalization issue: Store tax-related fields in a restricted compliance layer with lawful-use and privacy flags. Tax data is not an open marketing list or unrestricted public-company dataset. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: The main site may require SSL-unverified retry; certificate state should remain a QA flag.

NRA Taxpayer Identification Number

Authority and coverage: National Revenue Authority TIN guidance is classified as a tax layer. It contributes TIN definition, taxpayer categories and compliance context. The safe claim is narrow: Explains TIN use for individuals, commercial businesses, government departments and other taxpayers.

Access model and reuse: The live route is public taxpayer identification number page. Reuse should follow tax-guidance terms and attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use TIN evidence only where lawfully obtained and never as marketing-contact permission. TIN guidance does not publish a reusable taxpayer database. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Tax-administration process can change with ITAS updates.

NRA online TIN application

Authority and coverage: National Revenue Authority online TIN notice is classified as a tax layer. It contributes online TIN application steps, ITAS context and remote registration process. The safe claim is narrow: Shows remote TIN application workflow and ITAS context for individuals and businesses.

Access model and reuse: The live route is public NRA notice. Reuse should follow public notice attribution; no entity-list reuse right. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as workflow evidence and keep tax identifiers purpose-limited. Workflow announcement, not a company dataset. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: The notice is from a rollout period and should be checked against current NRA operations before procedural advice.

Sierra Leone Insurance Commission

Authority and coverage: Sierra Leone Insurance Commission is classified as a regulated layer. It contributes insurance-regulator provenance, regulated-sector context and market-supervision notes. The safe claim is narrow: Insurance-sector regulator context for licensed insurance entities and market supervision.

Access model and reuse: The live route is public insurance regulator portal. Reuse should follow SLICOM publication terms and financial-regulation limits. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Attach as a regulated-sector enrichment layer after resolving legal identity. Sector-specific and not a complete company register. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Regulator pages may be redesigned and licensing lists may have separate update cycles.

OAGMOJ gazettes

Authority and coverage: Office of the Attorney General and Ministry of Justice is classified as a legal layer. It contributes gazette route, publication date context and legal notice provenance. The safe claim is narrow: Legal-publication and gazette context for statutes, notices and company-law changes.

Access model and reuse: The live route is public gazette page. Reuse should follow government gazette terms and official-publication attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as legal evidence and source-update context, not as a full registry. Gazette pages are legal context, not a company master table. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Gazette posts can be paginated and attachment links need periodic checks.

SierraLII

Authority and coverage: SierraLII free access to law service is classified as a legal layer. It contributes primary and secondary legal materials, legislation and case/legal-publication context. The safe claim is narrow: Legal and statutory context for companies, procurement, investment and finance law.

Access model and reuse: The live route is public legal information portal. Reuse should follow free-access-to-law publication terms and source attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use to document legal basis and update risk behind registry and procurement workflows. Legal database, not registry data. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Legal coverage depends on publication ingestion cadence.

SierraLII gazettes 2025

Authority and coverage: SierraLII gazette archive is classified as a legal layer. It contributes gazette year archive, publication entries and legal-update context. The safe claim is narrow: Alternative legal-publication route for gazette monitoring and statutory changes.

Access model and reuse: The live route is public gazette archive page. Reuse should follow free-access-to-law/gazette attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use to support legal-update monitoring and source freshness flags. Archive and legal-publication layer, not company data. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Archive completeness depends on ingestion and publication schedules.

WIPO Lex Companies Act

Authority and coverage: WIPO Lex is classified as a legal layer. It contributes Companies Act reference, gazette citation and legal basis context. The safe claim is narrow: High-quality legal context for the Companies Act, 2009 and registry-law framing.

Access model and reuse: The live route is public legal reference page. Reuse should follow WIPO Lex terms and legal-source attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use for legal-basis notes and caution against overclaiming field availability. Legal reference, not current registry records. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: Legal amendments may require cross-checking with SierraLII/OAGMOJ.

ARIPO Sierra Leone

Authority and coverage: African Regional Intellectual Property Organization is classified as a ip layer. It contributes industrial-property office context, OARG IP contact and ARIPO membership information. The safe claim is narrow: IP-office context for Sierra Leone and the OARG role in industrial-property administration.

Access model and reuse: The live route is public member-state page. Reuse should follow ARIPO publication terms and attribution. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as IP enrichment where a company has trademark, patent or copyright evidence. IP layer only; not business-registration proof. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: IP contact details can change independently from the company register.

GLEIF LEI records for Sierra Leone

Authority and coverage: Global Legal Entity Identifier Foundation is classified as a lei layer. It contributes LEI, legal name, legal address, registration status and LEI reference-data metadata. The safe claim is narrow: Cross-border LEI enrichment for Sierra Leone entities that have LEIs.

Access model and reuse: The live route is public LEI API and downloadable reference data. Reuse should follow GLEIF open data licence. Public visibility does not create a general right to scrape, resell or convert the material into a marketing list.

Normalization issue: Use as high-confidence enrichment where an LEI exists; do not infer absence for non-LEI companies. Partial population and not a national registry replacement. CompaniesData should store source URL, access date, crawler result, source owner and field-level provenance for every value derived from this layer.

Update risk: GLEIF updates independently from domestic registry systems.

Practical Manual, API and Bulk Options

• Manual registry route: start with OARG company search. Capture the query, visible result, access date and whether a certified extract or manual registry request is needed.
• Registration workflow route: use NIB business-registration pages and SLIEPA guidance to explain the current process and form/resource routes.
• Tax route: use NRA TIN and online TIN application guidance for fiscal-identifier context only where the identifier is lawfully obtained.
• Procurement route: use NPPA bids and contract awards as supplier/activity events, not as proof of incorporation.
• Statistics route: hold direct Stats SL links until the final soft-block marker issue is cleared; keep statistics context separate from registry identity.
• Legal route: use OAGMOJ gazettes, SierraLII and WIPO Lex to document statutory context and watch for Companies Act updates.
• IP and regulated-sector route: use ARIPO for IP context and SLICOM for insurance-sector context while the OARG IP route and Bank of Sierra Leone route remain held.
• API route: use GLEIF for LEI-bearing Sierra Leone entities; store LEI status, legal name, address and GLEIF update timestamp.
• Bulk route: because no complete official all-company bulk file was verified, describe any commercial Sierra Leone dataset as normalized multi-source coverage, not a direct official register dump.

What Is Missing from Official Open Data?

The missing component is a clearly licensed, complete, downloadable company-register dataset with stable entity identifiers, company status, incorporation date, legal form, registered office, event history, update timestamps and machine-readable reuse terms. The current public evidence supports verification workflows and enrichment, not an unrestricted all-company database.

Beneficial ownership was not verified as a lawful public reusable dataset in this cycle. Director, shareholder, phone, email and beneficial-owner fields, if obtained through registry documents or manual searches, need separate lawful-use and privacy review. The article should therefore treat Sierra Leone as a structured verification jurisdiction rather than an open contact-data jurisdiction.

The main source-risk gap is that several high-value routes did not pass strict QA. OARG root and business-register pages returned server errors, the OARG IP route returned server errors, and Bank of Sierra Leone returned blank bot semantics. These routes should stay in the research backlog until they pass browser and bot-profile checks.

Recommended Data Model

• Entity identity: legal name, normalized name, country, entity type, OARG provenance, status where verified, match confidence and alternate names.
• Registry evidence: OARG search route, query term, visible result, access timestamp, document/extract reference and source-risk flag.
• Workflow evidence: NIB/SLIEPA registration guidance, form route, online-registration note and effective-date caveat.
• Tax evidence: TIN context, NRA source URL, lawful-use flag, privacy flag and whether the identifier is public, user-provided or document-derived.
• Activity evidence: NPPA tender or award event, procuring entity, supplier name, date, source URL and name-match confidence.
• Legal and specialist evidence: gazette/legal-source references, IP context, insurance-sector context, LEI enrichment and held-source status for banking/IP routes.
• Compliance controls: reuse note, no-endorsement note, GDPR/privacy caution, marketing-contact eligibility, suppression/opt-out state and audit trail.

CompaniesData Normalization and Enrichment Value

CompaniesData adds value in Sierra Leone because the official evidence is scattered across registry search, process pages, tax guidance, procurement notices, legal databases and specialist regulators. A buyer needs more than a list of links. They need deduplicated legal names, source provenance, field-level confidence, evidence dates, a clear split between official public records and private contact-data enrichment, and a record of which government routes were held because they failed QA.

Where CompaniesData helps: CompaniesData can normalize names from OARG, NPPA and GLEIF; reconcile supplier names against registry candidates; attach legal and tax context without overusing it; track source freshness; and keep held-source warnings visible for OARG and Bank of Sierra Leone routes. That makes the dataset more auditable than a scraped list.

Request a CompaniesData sample for Sierra Leone if you need a practical company dataset rather than a manual source tour.

FAQ

Is there a single free official bulk company database for Sierra Leone?

No. This refresh verified official workflow, tax, procurement, statistics, legal, regulator and LEI sources, but it did not verify a complete free official all-company bulk file or API.

What is the best first source?

Start with OARG company search, then use NIB and SLIEPA to understand registration workflow. Add NRA, NPPA, Stats SL, legal-publication sources, SLICOM, ARIPO and GLEIF only for specific enrichment questions.

Can tax or procurement data be used for email marketing?

No. Tax, procurement, registry and regulator sources do not create consent for business emails, phone lists or lead lists. Contact-data enrichment must be handled separately through CompaniesData.cloud with lawful-use checks.

Why include NPPA procurement?

NPPA can provide supplier and award context for companies that participate in public contracts. It is useful activity evidence, but it is not incorporation status and not universal coverage.

Why include legal sources?

Legal sources help users understand the Companies Act, public notices and statutory updates that shape company data. They are context sources, not entity lists.

Why was Bank of Sierra Leone held?

The central-bank page returned real browser content but blank Googlebot and Bingbot semantics from this node. Because crawler access is part of the publication standard, it stays research-only until repaired or replaced.

How should the dataset be refreshed?

Refresh OARG search and NIB routes frequently, retest held OARG/Bank routes, timestamp NPPA events, update NRA process notes when tax systems change, and refresh GLEIF through its API for LEI-bearing entities.
