Steps to validate an IBAN
There are two different validations that can be performed to ensure an UK IBAN is correct.
- 01First validation is done using the IBAN's Check Digits using the MOD97 algorithm.
- 02Second layer of validation can be carried out on the domestic sort code and account number combination
- 03Match the sort code against our Bank and Branch code directory to check if it exists
Found the correct IBAN, What to do next
With a Brazilian IBAN confirmed, here is what to do next.
- 01Verify the beneficiary's full registered name plus their CPF (individual) or CNPJ (company). Brazilian banks reject inbound wires when these do not match.
- 02Pair the IBAN with the bank's SWIFT/BIC, since Brazil uses IBAN only for inbound international transfers per BCB Circular 3.625.
- 03For local payments inside Brazil, ask whether the recipient prefers a PIX key (CPF, CNPJ, phone, email, or random key). PIX is free, instant, 24/7 and is the dominant domestic rail.
- 04Confirm whether the account is BRL only. Inbound USD is converted at the receiving bank at its FX margin.
- 05Send a small test transfer before a first-time large remittance.

IBAN Rules in Brazil
- 01IBAN is not mandatory inside Brazil. It exists purely as an international wrapper for inbound SWIFT payments, in force since Banco Central do Brasil Circular 3.625 in 2013.
- 02The Brazilian IBAN is 29 characters: BR, two check digits, an 8-digit ISPB bank code, a 5-digit branch (agencia) code, a 10-digit account number, a 1-letter account type (for example C for checking), and a 1-character account holder position.
- 03Domestically, Brazilians use ISPB plus agencia plus account, or far more commonly a PIX key. PIX has transformed retail payments since its November 2020 launch and now handles a huge share of consumer and business payments. IBAN's role is narrow but important: it is what foreign senders use to push money into a Brazilian account through SWIFT.
Brazil Payment Schemes
Brazil's payment landscape is dominated by PIX, with Banco Central do Brasil and CIP operating the underlying rails.
- 01PIX, Banco Central do Brasil, 24/7 instant retail and business payments, free for individuals, launched November 2020.
