Brazilian company databases: where to find B2B data on Brazil
The largest database of Brazilian companies is Receita Federal's CNPJ registry, published as monthly open data and covering tens of millions of establishments. Your options: download and process the open data (free, technical), use free CNPJ lookup sites (fine for one-off checks), or use B2B platforms that filter, enrich and export lists, some with built-in outreach, such as 1Lead. Global databases like Apollo or ZoomInfo cover large Brazilian companies better than small ones.
Sources compared
| Source | Cost | What you get | Limits |
|---|---|---|---|
| Open CNPJ data | Free | Every company, CNAE codes, address, registered contacts, partners, size | Large files, needs processing, Portuguese |
| Receita Federal CNPJ card | Free | One company at a time | No segment search |
| Brazilian CNPJ lookup sites | Free/freemium | Search by name, CNPJ, sometimes CNAE and city | Export limited or paid |
| Global B2B databases (Apollo, ZoomInfo, Lusha) | Subscription | People-centric contacts, strong for large companies | Thinner coverage of Brazilian SMBs |
| Brazilian prospecting platforms (data + outreach + CRM) | Subscription | CNPJ-based lists, email/WhatsApp sequences, pipeline | Interfaces usually in Portuguese |
Why global databases miss Brazilian SMBs
Global B2B databases are built mostly around professional profiles and company websites. Many Brazilian small and mid-size companies have little presence there, while every one of them has a CNPJ record with activity codes, size and registered contacts. For SMB-heavy segments (clinics, restaurants, retail, services), CNPJ-based data gives much broader coverage. See Apollo alternatives for Brazil.
Building a free lead list
- Pick CNAE codes and cities with IBGE's CONCLA search.
- Use the open data (if you have a data engineer) or a lookup site with CNAE search.
- Add Google Maps for local businesses.
- Manually verify the first 50 contacts before scaling.
"Free" costs time. For volume, a paid platform is usually cheaper than your team's hours.
