The digital signature service provided by the Federal Government through the gov.br portal has exceeded the mark of 548 million uses. This usage volume includes a significant growth of 143 million signatures registered in the first six months of 2026 alone.
Surpassing Goals and Growth
The Federal Government announced that the digital signature service, accessible via the gov.br website, not only met the established goal of 540 million uses by the end of 2026 but surpassed it. This functionality is ideal for documents that are already digitized and adds important data such as the user's CPF and the exact time of signing, thus replacing the need for manual signatures and simplifying bureaucratic procedures.
Data released by the government points to a significant increase in 2026, with 143 million signatures in the first six months. This number is higher than the 95.3 million uses recorded in 2025, which was already a record compared to previous years.
How to Use Electronic Signature
To perform the Electronic Signature, the user must access sso.acesso.gov.br and log in using their gov.br account, the same one used for Income Tax declarations or to access platforms like Tela Brasil, MEC Livros, and MEC Idiomas. Furthermore, the portal offers other free services provided by the Government.
The tool was described in the government announcement as a 'favorite,' highlighting the high adoption rate by the population in recent years. The goal set by the Federal Digital Government Strategy (EFGD) for 2026 was achieved ahead of schedule, totaling 548 million uses since its operation began. This represents a 25-fold increase in signatures made on the Government platform compared to the frequency observed in 2022.
Benefits and Practical Operation
Rogério Mascarenhas, Secretary of Digital Government, stated that the tool assists in the daily lives of the 177 million Brazilians who use gov.br. The website is essential for many mandatory activities, such as filing Income Tax returns. The service drastically simplifies the process, eliminating the step of printing, physical signing, and subsequent digitization of documents.
With the platform, users simply upload the document in PDF format, indicate the signing location, and send it. This facilitates the resolution of bureaucratic issues related to work, formalizing purchases and sales, or providing services. The service is free, but requires the user to have an active login on Gov.br and access to the mobile application to authenticate both access and document generation.
Steps to Sign and Validation
The process involves going to sso.acesso.gov.br and logging into gov.br, selecting the digital signature option. Next, the user clicks the '+' icon to attach the file (dragging the document is also possible), proceeds, and positions the 'Signature Area' box in the desired location. After clicking 'Sign,' authentication via a notification received in the Gov.br application is required, where a code must be entered. The resulting file is generated in PDF format and can be downloaded to the device. The procedure can also be carried out directly through the gov.br mobile application, where Electronic Signature is listed among the main options.
To ensure the document's authenticity, the government recommends validating the signature through the link validar.iti.gov.br. This resource also allows verification of third-party signatures, either through the mentioned link or via the Validar QR Code application, available for Android and iOS systems.
