e-CPF digital certificateTo sign as an individual.

The e-CPF is your digital identity as an individual (CPF is the Brazilian individual taxpayer ID). With it you access e-CAC, file and track your income tax return, sign legally valid contracts and powers of attorney, and log in to public portals that require a certificate.

What it's for

What you can do with the e-CPF.

Income tax returns and e-CAC (Brazil's Federal Revenue portal)

Signing contracts and powers of attorney

Gold-level gov.br account and access to public portals

Documents

What to have on hand for validation.

  • Photo ID — Brazilian driver's license (CNH) or ID card (RG)
  • The original paper document on the day of validation

Under ITI Normative Instruction No. 36/2026, the ID shown on the video call must be the original paper document. Only have a digital ID? Then validation is in person in Extrema.

How it works

From order to installed certificate.

  1. Build your certificate and send the order.
  2. Pay by Credit card, Pix (instant payment) or Boleto (bank slip).
  3. Validate by video call (about 15 minutes) or in person in Extrema.
  4. Immediate issuance after approval, with installation via remote access included.

A1, A3 or Cloud

The difference is where the certificate is kept.

A1 · file

Stays on the computer

Installed on a single machine, valid for 12 months. Ideal for issuing invoices from a fixed system.

A3 · token or card

Goes with you

Portable physical media, valid for 12, 24 or 36 months. For when a system specifically requires a token.

Cloud

Sign from your phone

No token and nothing to install, valid for 12, 24 or 36 months. Works on any computer or phone.

Questions

What people ask about the e-CPF.

What is the e-CPF used for?
To access e-CAC at Brazil's Federal Revenue Service, sign legally valid documents, log in to government portals and use systems that require ICP-Brasil identification.
Do freelancers need an e-CPF?
Usually yes, if you issue invoices through the city hall portal, access e-CAC or sign contracts digitally. If you have a registered company, consider the e-CNPJ as well.
How long does it take?
The certificate is issued immediately once validation is approved. Customers who buy in the morning with their documents in order are usually signing the same day.
Do I need to travel to Extrema?
No. Video validation serves all of Brazil. In-person service in Extrema, MG, is there for those who prefer it, for those who only have a digital ID, and for cases where the rules require being present.
Which should I choose: A1, A3 or Cloud?
If you issue invoices from software installed on a single computer, A1 does the job and costs less. If you sign from your phone, travel or use more than one computer, Cloud saves you headaches. An A3 token makes sense when some system requires physical media.
