The Central Bank of Brazil published Resolution BCB No. 457, dated March 6, 2025, amending the regulations of the Pix payment arrangement, originally established by Resolution BCB No. 1, dated August 12, 2020. The changes aim to strengthen security mechanisms in the use of the system, with emphasis on stricter validations and adjustments to processes related to Pix keys.

Among the main changes are requirements for validating the end user's ownership of the Pix key, obtaining consent, and validating the name linked to the key against records held by the CPF or CNPJ databases.

In addition, Pix participants must ensure that information linked to keys is consistent with data maintained by the Brazilian Federal Revenue Service (Receita Federal). Corrections may be made without user consent as long as they do not constitute fraud. Keys linked to CPFs or CNPJs with irregular status at the Receita Federal will also be excluded from the system.

Another significant change is the mandatory pre-registration of devices for individuals to initiate Pix transactions. Exceptions may apply to unregistered devices under specific conditions defined by the Central Bank. New parameters for the portability and ownership claiming of Pix keys were also established, in accordance with the DICT Operational Manual guidelines.

The resolution sets different effective dates for the amendments, with some provisions applicable immediately and others taking effect in April, July, and October 2025.
