Check whether a Timor-Leste IBAN is valid — country, length and mod-97 checksum — and break out the bank details. Instant and free, right in your browser.
| Country | Timor-Leste (TL) |
| IBAN length | 23 characters |
| Structure | TL + 2 check digits + 19-character BBAN |
| Valid example | TL31 7654 3210 9876 5432 109 |
Every Timor-Leste IBAN starts with TL and is 23 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 Timor-Leste IBAN is exactly 23 characters long, beginning with the country code TL followed by two check digits and the national bank account number (BBAN).
A correctly-formed example is TL31 7654 3210 9876 5432 109. The two digits after TL are a mod-97 checksum that must match the rest of the number.
By confirming it is 23 characters, starts with TL, and passes the ISO 7064 mod-97 checksum. The tool above does all three instantly, in your browser — no data is sent anywhere.
