Federal Revenue Launches Tool to Block CPF Against Fraud: Free Resource Prevents Opening of Companies in Your Name Without Authorization
According to accountant Lavínia Ramos, the Federal Revenue tool represents an important advance in protecting citizens against fraud. It is now possible to block your CPF for free to prevent criminals from using your data to open companies, including as MEI or in any other CNPJ.
In practice, the resource prevents future debts and legal issues that could arise if the CPF were used without authorization. The system is already available on the gov.br portal and can be activated in a few minutes.
How Does the Federal Revenue Tool Work?
The Federal Revenue tool is named CPF Protection. It allows the holder to block or unblock the CPF for participation in corporate registries of companies throughout Brazil. This block applies to commercial boards, notaries, OAB, and other registering agencies.

Havan will leave the shopping mall in Blumenau to inaugurate something that the chain has never done before: a megastore in half-timbered style in the Historic Center of the city, which is expected to be completed in May and change the landscape of local retail.
The mechanism is simple: by activating the block, no one can use your CPF to open or alter companies. If the holder wants to open their own business, they just need to temporarily unblock, complete the process, and block it again.
What Are the Benefits of Blocking the CPF?
Among the advantages of the Federal Revenue tool are the prevention of fraud and legal security. Citizens avoid being surprised by companies opened in their name and debts they did not incur.
Additionally, the tool benefits public servants who cannot have an active CNPJ. The block ensures legal compliance and protects against misuse of data. For future entrepreneurs, the protection also prevents unpleasant discoveries, such as already being listed as a partner in another company.
Who Can Use It and How to Activate?
The functionality is valid for anyone with an account on gov.br. Simply access the RedeSim portal, click on “Protect My CPF,” confirm the declaration, and activate the block. Unblocking follows the same process, with a security authentication sent to the user’s mobile phone.
Another important point is that the tool also allows checking if a company is already linked to the CPF. This quick check helps identify any frauds that may have already occurred.
Is It Worth Activating the Protection?
Yes. In a scenario of increasing digital scams and data breaches, the Federal Revenue tool serves as an extra layer of security. It protects citizens from unexpected debts, legal proceedings, and even obstacles to opening their own business in the future.
Experts say that due to the ease and free nature of the resource, adoption is expected to grow rapidly among those looking to safeguard themselves against fraud.
The Federal Revenue tool gives citizens control over the use of their CPF in company openings and alterations. With the block active, common scams in the market become nearly unfeasible.
