Use this country index to find CompaniesData guides about official company registers, open company data sources, public APIs, reuse rights and commercial contact-data boundaries. Each guide separates official company-identity data from marketing-contact data, so buyers can evaluate source quality before requesting an Excel database, lead sample or custom extraction.

Priority open company data guides

These markets are priority crawl targets because they are commercially important, recently updated, or had weak Google discovery signals in the latest Search Console audit.

All open company data country guides

The full library covers official company registries, open-data portals, procurement sources, regulator datasets, LEI context and reuse constraints by country.

From official sources to usable company databases

Open registries are useful for verification, but they do not automatically provide CRM-ready emails, phone numbers, company segmentation or lawful outreach permission. For commercial datasets, start with the guide for the country, then compare the available Excel database or request a sample from CompaniesData.
