Gov.br digital signature surpasses 548 million uses in Brazil

The free digital signature tool on the gov.br portal has already surpassed the milestone of 548 million uses nationwide, beating a goal originally forecast for late 2026. In the first six months of the year alone, 143 million new signatures were registered on the platform.

How the digital signature works

The service is straightforward and designed for simplicity. To use it, users just need a digital document, such as a PDF, and access the government signature portal. The step-by-step process is quick:

• Visit sso.acesso.gov.br via computer or mobile device;
• Log in with your silver- or gold-level gov.br account;
• Upload the file you wish to sign;
• Select where the signature will appear on the document;
• Validate the action in the gov.br app and finalize.

After completing the process, the digitally signed document is available for download. It features a verification code that ensures its authenticity and legal validity for most purposes, across both the public and private sectors.

How much you can save

The main financial benefit for citizens is that signing via gov.br is completely free. In contrast, document notarization at a notary office carries fees that vary by state, generally ranging from R$ 10 to R$ 30 per document. For those who need to validate multiple contracts or declarations throughout the year, the savings can be significant.

Document validity and security

This digital tool allows any citizen with a silver- or gold-level gov.br account to validate documents with the same legal security as in-person notarization. The entire process is online, eliminating the need for travel and the payment of notary fees, known as emoluments.

Where to use the digital tool

The tool can be used for rental agreements, vehicle sales contracts, work reports, and several other documents that previously required a visit to a notary office. However, it is important to check the requirements for each specific case. Acts requiring public faith, such as real estate deed transfers, must still be conducted in person.
