Tunisia IBAN validator
How the IBAN format works
- Format
- TN + 2 check digits + 20-digit bank/branch/account number (24 chars)
- Example
- TN5910006035183598478831
Things to watch for
- 24 characters total, all numeric after the country code
- Checks structure and checksum only, not that the account exists
^TN[0-9]{2}[0-9]{20}$A Tunisian IBAN is 24 characters, and every character after “TN” and the two check digits is a plain digit — 20 of them, covering the bank, branch, and account number as one continuous numeric block. Tunisia is one of the relative handful of countries in Africa and the Arab world where the Central Bank of Tunisia requires IBAN for domestic transfers as well as international ones, a legacy of the French-influenced RIB (relevé d’identité bancaire) numbering banks there used before IBAN. That history is also why the format is entirely digits with no letter-based check code layered on top, unlike some of its European counterparts.
How this validator works
This tool checks for the “TN” prefix, confirms exactly 20 digits follow the two check digits with no letters present, and then runs the mod-97 (ISO 7064) checksum a correctly generated Tunisian IBAN must satisfy — all inside your browser, with nothing transmitted to a server and no signup required.
What a pass doesn’t tell you
A pass confirms the 24 digits are structurally sound and pass the checksum, not that the account is open, active, or belongs to the person or business you intend to pay. This validator has no connection to any Tunisian bank or the Central Bank of Tunisia and performs no name-matching. If a Tunisian IBAN fails, recount the digit groups against the source document first — an unbroken 20-digit numeric string is easy to mis-split when typing from a statement or invoice.
Scope: structure and mod-97 checksum validation for Tunisian IBANs only — not payment processing, bank verification, or proof an account is active. Catch the typo here; confirm the account with your bank.

IBAN FAQ
What does a Tunisian IBAN look like?
24 characters, all numbers after the prefix: 'TN', two check digits, then 20 digits covering the bank, branch, and account identifiers together — for example TN5910006035183598478831. There are no letters anywhere in a Tunisian IBAN.
Is IBAN actually required for domestic transfers in Tunisia?
Yes — Tunisia is one of a smaller number of African and Arab-world economies where the Central Bank of Tunisia requires the IBAN format for domestic bank transfers, not just international ones, so a Tunisian IBAN is the everyday account identifier, not a special international-only version.
Does a pass here mean my Tunisian transfer will succeed?
A pass only confirms the 24 digits are correctly structured and satisfy the mod-97 checksum. It doesn't confirm the account exists, is open, or is held by the right person, and this tool never contacts a Tunisian bank — actual transfer success still depends on your bank's processing.
