Check whether a Bulgaria IBAN is valid — country, length and mod-97 checksum — and break out the bank details. Instant and free, right in your browser.
| Country | Bulgaria (BG) |
| IBAN length | 22 characters |
| Structure | BG + 2 check digits + 18-character BBAN |
| Valid example | BG98 7654 3210 9876 5432 10 |
Every Bulgaria IBAN starts with BG and is 22 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 Bulgaria IBAN is exactly 22 characters long, beginning with the country code BG followed by two check digits and the national bank account number (BBAN).
A correctly-formed example is BG98 7654 3210 9876 5432 10. The two digits after BG are a mod-97 checksum that must match the rest of the number.
By confirming it is 22 characters, starts with BG, and passes the ISO 7064 mod-97 checksum. The tool above does all three instantly, in your browser — no data is sent anywhere.
