Central Bank Requires Exclusion of Irregular Pix Keys to Increase System Security. See How the Measure May Impact Individuals and Businesses.

Pix key exclusion announced: The Central Bank (BC) announced new measures to increase the security of Pix, requiring banks and financial institutions to exclude Pix keys from individuals and legal entities with irregular situations in the Federal Revenue Service. The decision was published last Thursday (6) and is part of a set of changes to the regulation of the instant payment system. Check out all the details below!

Which Pix Keys Will Be Excluded

According to the Central Bank, banks and other financial institutions must exclude Pix keys linked to CPFs and CNPJs with registration irregularities in the Federal Revenue Service. The affected cases are:

Individuals (CPF)

Situation “suspended”
Situation “canceled”
Situation “null”
Deceased holder

Businesses (CNPJ)

Situation “suspended”
Situation “inactive”
Situation “canceled”
Situation “null”

If a CPF or CNPJ falls into any of these categories, the Pix keys linked to it will be automatically excluded. The BC made it clear that this restriction is not related to tax payments. In other words, tax delinquency will not be a reason for exclusion of the key.

The main objective of the measure is to prevent frauds and scams in Pix. According to the BC, many criminals use irregular CPFs and CNPJs to commit fraud by registering keys with names different from the official records of the Federal Revenue Service.

Now, financial institutions will have to ensure that the names associated with Pix keys exactly match what is registered with the Federal Revenue Service. The Central Bank will also conduct continuous monitoring and may impose penalties on institutions that do not follow the guidelines correctly.

“The Central Bank emphasized that the approved measures do not change the way people and businesses make or receive Pix transactions. They are operational and increase the security of the system to combat fraud,” stated the BC in an official note.

Other Changes in the Pix Regulation

In addition to the exclusion of irregular Pix keys, the BC also announced other measures to strengthen system security. Among the main changes are:

End of data alteration in random keys: Now, individuals and businesses will no longer be able to modify the information linked to random keys. If they want to change any data, they will need to delete the old key and create a new one.
Pix keys of the email type cannot be transferred to another owner: The BC prohibited the claim of ownership of Pix keys of the email type. This means that an email registered as a Pix key cannot be transferred to another holder.
Exception: Only keys registered with mobile phone numbers may be transferred to another user. This is because prepaid phone numbers can frequently change ownership.

Ease of Returning Funds via Pix

The BC also allowed the return of any amount from unregistered devices. Previously, the rule limited transactions initiated from unknown devices to R$ 200. However, this was preventing the voluntary return of incorrectly received funds. Now, users will be able to return any amount without this restriction.

What Does This Change for Pix Users?

If your CPF or CNPJ is regular with the Federal Revenue Service, nothing changes for you. Pix will continue to function normally, and you will be able to send and receive payments without any impact. On the other hand, those with irregular CPFs or CNPJs need to resolve the situation with the Federal Revenue Service to avoid losing their Pix key.

Summary of Main Changes:

✔ Pix keys of irregular CPFs and CNPJs will be excluded
✔ Data changes in random keys are not allowed
✔ Email keys cannot be transferred
✔ Returns of funds are now permitted without the R$ 200 limit on unregistered devices
