Returned Fields

What the registration lookup returns

Name and document

Full name (or legal name), CPF/CNPJ and status at the tax authority.

Phone numbers

Landlines and mobiles, with carrier and WhatsApp flag.

Addresses

Known addresses with street, district, city, state and postal code.

Emails

Email addresses linked to the record.

Profile and income

Social class, estimated income and occupation (CBO) for individuals.

Ownership and partners

Shareholdings and the list of partners for companies.

Use Cases

From customer onboarding to database enrichment

A single API key unlocks 100+ endpoints — from a R$ 0,16 basic registry lookup to a full credit report.

Onboarding and Registration Checks

Fintechs, marketplaces, insurers and SaaS platforms

Check whether the CPF or CNPJ exists, is in good standing at the tax authority and matches the name given — before approving the account. One call, an answer in seconds, no manual review.

Database Enrichment and CRM

Marketing, growth and data teams

You have only the CPF or CNPJ — we return phone, email and address to complete the record. From R$ 0,29 per enriched row.

Collections and Skip Tracing

Collections, credit recovery and back office

Find people who went silent: every known phone (with WhatsApp flag), alternative addresses and emails — plus a death check, so you never chase someone who has passed away.

Company Tax Records

Procurement, tax and invoicing

Before invoicing or onboarding a supplier: status at the tax authority, Simples Nacional tax regime, state registration in Sintegra and the company's list of partners.
