Pix exceeds 1 billion registered keys in Brazil

The number of Pix keys registered in Brazil surpassed the 1 billion mark in September, according to data from the Central Bank (BC). In total, the system recorded 1.008 billion records on the 30th, compared to 998 million in August. The total represents an increase of approximately 80 million keys since the end of 2025, when there were 920 million.

The number of keys, however, does not correspond to the number of users in the system. As the same person can register more than one key, Pix brings together around 170 million customers, including individuals and companies. This means an average of close to six keys per customer, considering the approximate numbers.

Of the total records, 956.7 million were linked to individuals and 51.2 million to companies, according to BC data.

More than half of the registrations correspond to random keys, which allow you to receive transfers without having to share personal information, such as Individual Taxpayer Registration (CPF), telephone number or email.

Check the distribution by key type:

Random: 526.8 million (52.3%);

Cell phones: 166.3 million (16.5%);

CPF: 153.9 million (15.4%);

Emails: 144.6 million (14.3%).

How they work

Pix keys are identifiers associated with a bank or payment account and make it easier to send and receive money. The user can register CPF, National Register of Legal Entities (CNPJ), cell phone number, email address or a random key generated by the financial institution.

Individuals can register up to five keys per account, companies can register up to 20. Each key can only be linked to one account at a time.

Registration and management are carried out through the financial institution's application or internet banking. The Pix key, however, is not mandatory, it is also possible to make transfers using the recipient's bank details, in addition to resources such as QR Code.

Transaction volume

The increase in the number of keys follows the use of Pix for everyday transfers and payments. In September, 7.1 billion transactions were processed by the Central Bank's Instant Payment System (SPI), transacting approximately R$3.2 trillion.

SPI processes and settles transfers between different financial institutions in real time. Operations carried out between clients of the same institution can be settled internally, without going through the BC system.

Registration security

The random key allows you to receive values without directly disclosing personal data. Still, users must verify the recipient's identity before confirming a transfer.

In November 2025, the Central Bank reported that it was studying mechanisms to allow blocking the creation of new unauthorized keys, as an additional fraud prevention measure.
