Check whether a Guatemala IBAN is valid — country, length and mod-97 checksum — and break out the bank details. Instant and free, right in your browser.
| Country | Guatemala (GT) |
| IBAN length | 28 characters |
| Structure | GT + 2 check digits + 24-character BBAN |
| Valid example | GT53 7654 3210 9876 5432 1098 7654 |
Every Guatemala IBAN starts with GT and is 28 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 Guatemala IBAN is exactly 28 characters long, beginning with the country code GT followed by two check digits and the national bank account number (BBAN).
A correctly-formed example is GT53 7654 3210 9876 5432 1098 7654. The two digits after GT are a mod-97 checksum that must match the rest of the number.
By confirming it is 28 characters, starts with GT, and passes the ISO 7064 mod-97 checksum. The tool above does all three instantly, in your browser — no data is sent anywhere.
