Check whether a Brazil IBAN is valid — country, length and mod-97 checksum — and break out the bank details. Instant and free, right in your browser.
| Country | Brazil (BR) |
| IBAN length | 29 characters |
| Structure | BR + 2 check digits + 25-character BBAN |
| Valid example | BR48 7654 3210 9876 5432 1098 7654 3 |
Every Brazil IBAN starts with BR and is 29 characters long. The two digits after the country code are a checksum (ISO 7064 mod-97) computed from the rest of the number, so a single mistyped character makes the whole IBAN invalid — which is exactly what this validator catches before a payment is sent.
A Brazil IBAN is exactly 29 characters long, beginning with the country code BR followed by two check digits and the national bank account number (BBAN).
A correctly-formed example is BR48 7654 3210 9876 5432 1098 7654 3. The two digits after BR are a mod-97 checksum that must match the rest of the number.
By confirming it is 29 characters, starts with BR, and passes the ISO 7064 mod-97 checksum. The tool above does all three instantly, in your browser — no data is sent anywhere.
