Romania Business Registry (ONRC Trade Register) & Open Business Companies Data: CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number), Official Portals & Master Data

What You Need to Know at a Glance: Romania Business Registry & Company Master Data (ONRC Trade Register)

In Romania, statutory entity identity begins with National Trade Register Office (ONRC — Oficiul Național al Registrului Comerțului) and the assignment of a formal CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number). Rather than residing in a single monolithic file, Romania’s public business registry ecosystem spans 11 official government, regulatory, and statistical sources overseen by ONRC, National Trade Register Office, data.gov.ro, Government of Romania. Primary legal-entity lookup routes include Trade Register information (ONRC) and ONRC portal (National Trade Register Office).

To supplement statutory registration records from ONRC Trade Register, official verification workflows in Romania draw upon fiscal and taxpayer registration via Ministry of Finance company data (mfinante.gov.ro, Ministry of Finance) and ANAF services (National Agency for Fiscal Administration); open data catalogues and statistical business frames through ONRC open datasets (data.gov.ro) and Romanian open-data portal (Government of Romania); financial supervision, capital-market disclosures, and LEI records from Competition Council (Romania); public procurement notices, official gazettes, and intellectual-property registers such as SICAP / SEAP procurement (www.e-licitatie.ro, Public procurement system) and OSIM (State Office for Inventions and Trademarks).

How the Official Romania Business Registry (ONRC Trade Register) & Public Data Ecosystem Work

The strongest route is ONRC trade-register services and ONRC datasets on data.gov.ro, combined with finance, fiscal, procurement and regulator layers. That makes Romania a public but operationally fragmented company-data market, but it does not remove the usual reuse checks: dataset terms, attribution, no-endorsement language, privacy, marketing-law boundaries and source freshness.

Romania is a strong Burst A candidate because official ONRC open-data snapshots exist, even though full operational access remains split across portals and services.

For practical work, the most useful source stack is: Trade Register information, ONRC portal, ONRC open datasets, Romanian open-data portal, National Institute of Statistics, Ministry of Finance company data.

Operational Scope, Access Workflows & What Is Missing from Public Romania Registry Records

Romania has public company information through ONRC and datasets on data.gov.ro, but ONRC information delivery is more fee/request/portal-oriented than a simple open API. Open-data evidence exists for registered-company datasets, while ANAF/Ministry of Finance and commercial APIs are separate enrichment routes.

• CKAN/API access to data.gov.ro is not the same as a live transactional ONRC API.
• Dataset dates and field coverage need checking before reuse.
• Fiscal, finance and trade-register records are separate layers.

Frequently Asked Questions: Romania Business Registry (ONRC Trade Register) & Company Data

How can I run an official company register search in Romania using the CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number)?

Official corporate verification in Romania is conducted through National Trade Register Office (ONRC — Oficiul Național al Registrului Comerțului), where legal entities are indexed under their statutory CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number). Depending on the entity type and filing layer, primary verification portals include Trade Register information (ONRC) and ONRC portal (National Trade Register Office). Always record the exact registration number and issuing authority shown on the official extract.

What open data portals and programmatic endpoints exist for Romania company data?

In Romania, public-sector open data and statistical corporate datasets are published through ONRC open datasets (data.gov.ro), Romanian open-data portal (Government of Romania), and National Institute of Statistics (INSSE), alongside core registry lookups at ONRC Trade Register. However, each portal applies its own schema, update cadence, and dataset-specific reuse terms (Registered-company datasets), so programmatic ingestion requires linking records back to the statutory CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number).

How do tax authorities and financial regulators in Romania complement ONRC Trade Register records?

Alongside core corporate registration in ONRC Trade Register under the CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number), fiscal and financial-sector verification in Romania draws upon Ministry of Finance company data (mfinante.gov.ro, Ministry of Finance), ANAF services (National Agency for Fiscal Administration), and Competition Council (Romania). These authorities maintain taxpayer compliance records, supervised financial-institution directories, and regulatory disclosures separately from general commercial incorporation filings.

Which official portals in Romania cover public procurement, official gazettes, and intellectual property?

Beyond core registration in National Trade Register Office (ONRC — Oficiul Național al Registrului Comerțului), researchers tracking government contractors, statutory notices, or brand ownership in Romania can consult SICAP / SEAP procurement (www.e-licitatie.ro, Public procurement system) and OSIM (State Office for Inventions and Trademarks). Because these portals index participating suppliers, published legal notices, or registered rights holders, they function as enrichment layers keyed to the entity’s CUI / CIF (Unique Registration Code) & Nr. de Ordine în Reg. Com. (J-Number).

What is the best first source for Romania company data?

The best first source is ONRC trade-register services and ONRC datasets on data.gov.ro, combined with finance, fiscal, procurement and regulator layers. It should then be combined with statistics, procurement, IP and regulator sources.
