Pix Participating Institutions
Every time a Pix key resolves to an account, there is an institution behind it: the participant. Brazil's Central Bank keeps the official list of who can operate on Pix, with its own identifier for each one, the ISPB. This tool searches that registry right in the browser, over a snapshot with a visible generation date.
Itaú settles directly through the STR without depending on another institution to close the operation, the typical profile for a bank that has held its own account at the Central Bank since before Pix existed.
Payment institutions like this one hold customer accounts but have no direct seat on the STR, so settlement passes through a direct participant hired for that function.
A Payment Transaction Initiator triggers a Pix transfer at the user's request from inside another app, but it never holds the money itself: whoever custodies the account is always a different participant.
Yes, and that is the main use. The search covers the full name and the short name, so typing part of a name already filters the list as you write. To open the record directly by identifier, enter the 8-digit ISPB.
The Pix key is the nickname that points to an account (a CPF, CNPJ, email, phone number, or a random key); the ISPB is the 8-digit number that identifies the financial institution that owns that account. When a Pix transfer runs, the system resolves the key until it finds the responsible participant's ISPB, then routes the transfer there.
Only after clearing the Central Bank's authorization process and signing the Pix Adhesion Term. The institution then joins as a direct or indirect participant and receives its own ISPB, which then appears on the public list Bacen maintains.
Keeping a direct settlement account at the Central Bank and the infrastructure to access the STR is expensive and comes with heavy regulatory demands. Smaller fintechs prefer hiring a direct participant to bridge that gap, which lowers the barrier to entry without removing the indirect institution from the official participant list.
It identifies public agencies that join the arrangement for the government's own operations, such as the National Treasury Secretariat, rather than commercial banks or fintechs. It is a separate category because the role these institutions play on Pix differs from that of a provider serving the general public.
The official list of institutions in Brazil's Pix arrangement, not just the big banks. Search by the name you know or by ISPB, and filter by participation type and modality.
