How to find a Brazilian company's email and phone number from its CNPJ
Brazil's CNPJ registry includes the phone number and email the company declared when it registered or last updated its record. You can see them by looking up the CNPJ in tools built on Receita Federal's open data, or filter whole lists by contact availability in platforms like 1Lead. These contacts are often generic (sometimes the accountant's), so combine them with the company website and the partner names in the shareholder list (QSA) to reach the decision-maker.
What the CNPJ record contains
Receita Federal's open CNPJ data includes, per establishment: phone numbers with area code, email, full address, CNAE codes, registration status and opening date. The partner list (QSA) has names and roles of partners and administrators, with personal tax IDs partially masked.
Limits of registry contacts
- May be outdated: companies don't always update their record.
- May belong to the accountant: many CNPJs are opened with the accounting firm's email.
- Usually generic: rarely the decision-maker's own address.
Reaching the decision-maker
- Look up the CNPJ: note phone, email and partners.
- Check the website and social profiles for sales contacts and WhatsApp.
- Identify the decision-maker: in small companies, usually a managing partner (*sócio-administrador*).
- Verify emails before sending at volume.
- Record the data source (public registry, date) to answer data-subject requests under LGPD.
At scale, filter whole lists by contact availability and partners instead of looking up one CNPJ at a time; 1Lead does this alongside CNAE, city and size filters.
Frequently asked questions
Is the CNPJ email public?
Yes. The email and phone declared in the registration are part of Receita Federal's open data. Using them for B2B outreach must respect LGPD when the data identifies a person.
How do I find the owner of a Brazilian company?
The QSA (shareholder and administrator list), published in the open data and on the CNPJ card, lists each partner's name and role.
