In order to prevent fraud through the registration of individuals, it is now possible to request the blocking of personal data. So the CPF Protection Service was released on Wednesday (28) in the State of São Paulo. The resource is already available through the Redesim portal and costs a fee of R$ 3.77.
The project was developed by the Secretariat for Economic Development, based on the Board of Trade of the State of São Paulo (Jucesp). Any citizen of SP can access the State Integrator system, also known as Redesim, and request the blocking of their personal data.
In this way, information such as the CPF will be prevented from being used by third parties without the owner’s consent.
On the other hand, it is important to highlight that the interruption is only valid for one month. That is, it is necessary to renew the order monthly, always disbursing the amount of R$ 3.77. In situations of stolen, stolen or lost documents, there is no charge. However, there is a need to present a police report or declaration of poverty.
If, for any reason, the citizen wishes to unblock their personal data, it will be necessary to request it through the “Contact Us” channel of the portal. This option is free.
How to block your CPF

- Then, log in with your Gov.BR account;
- On your profile page, scroll down until you find the “CPF Protection” option;

It is worth pointing out that when requesting the block, the person will no longer be able to open companies or make changes that involve members with the blocked CPF.

Data leak gave headache in 2021
In early 2021, a blow occurred in the country’s systems, when a hacker announced that he had stolen 223 million CPFs.
As a result, the criminal put up lots of information for sale, not even the deceased escaped the leak. Data such as full name, date of birth and gender of many individuals were exposed in an internet forum.
From then on, both the STF and the OAB pressured the ANPD (National Agency for the Defense of the Saver) to thoroughly investigate what happened. Consequently, the Federal Police carried out an operation and ended up arresting a suspect.
In any case, the novelty that allows CPF blocking is an interesting step towards data protection, something so complex in a highly connected world.
