With more than 20 million active CNPJs — including roughly 15 million MEI microentrepreneurs — Brazil is Latin America's largest business base, and the Receita Federal publishes the full CNPJ register as open data. AtlasForgeX reads that base and the wider Brazilian web to surface companies stored databases overlook.
Industries. Services, agribusiness, manufacturing and a vast retail and trade sector lead.
Regions. São Paulo dominates, followed by Rio de Janeiro, Minas Gerais and the southern industrial states.
The legal source of truth for Brazil is CNPJ (Receita Federal). It records every legally trading company — identifier, status, address and often officers and filings — which is why it is the most complete and current starting point for prospecting. See the full register directory.
Databases like Apollo and ZoomInfo do not know companies — they assemble records from contributory networks, purchased lists and web scraping, all skewed toward firms with a strong English-language online footprint. A MEI services provider in Minas Gerais has an open CNPJ record and a Portuguese-language presence, but is not in a US-built warehouse.
| Segment | Share of firms | Online-footprint coverage |
|---|---|---|
| Large + mid | ~small share | Partial — bigger firms covered |
| Small (PME) | several million | Variable |
| MEI / micro | ~15M | Weak — largely absent |
Brazilian businesses — overwhelmingly MEI and micro-firms — are absent from online-footprint databases despite open CNPJ data. A structure-based estimate, not a figure measured from any database.
The national identifier is the CNPJ (Cadastro Nacional da Pessoa Jurídica), a 14-digit number administered by the Receita Federal. Incorporation itself is handled by state commercial boards — the Juntas Comerciais — while micro-entrepreneurs register as MEI through the Portal do Empreendedor. Crucially, the Receita publishes the entire CNPJ base as open data (Dados Abertos), refreshed monthly, with each record carrying status, address, the primary CNAE activity code and partner details. It is one of the most complete open company datasets anywhere.
Openness, however, has not produced coverage in commercial databases. The roughly 15 million MEI and small firms typically trade through Instagram, WhatsApp and marketplaces instead of a website, publish only in Portuguese, and are spread far beyond São Paulo into states such as Bahia, Pará and Goiás. Aggregators that lean on English-language web presence and contributed contacts ingest only a thin top layer of the largest firms. Atlas works from the CNPJ open data and the Brazilian-language web directly, which is how it reaches companies that never appear in a stored list.
