About CPFHub.io
Verifying a CPF in Brazil
shouldn't be hard.
Since 2024, CPFHub.io has helped Brazilian companies confirm that a CPF (Brazil's individual taxpayer ID) belongs to the person who claims it. One API call, a response in ~150 ms and LGPD (Brazil's data protection law) compliance from the first endpoint.

Why we exist
We built the API we wanted to use.
In 2024, verifying a CPF still meant PDF documentation, a signed contract before the first test and pricing on request.
We took the opposite path: a single GET call, open documentation, a free plan with no credit card and no charge for a CPF that is not found.
Today, more than 6,000 companies use CPFHub.io, from independent developers to fintechs.
Our mission
To let any Brazilian company, from the independent developer to the fintech, confirm its customers' identity in a way that is simple, accessible and compliant with LGPD.
Our journey
On the market since 2024. Evolving every month.
Every release came from a real request from people who verify CPFs every day.
