IBAN Structure Tunisia

Last reviewed: · Source: ISO 13616 / SWIFT IBAN Registry

Tunisia's IBAN has 24 characters in the format TNkk BBSS SCCC CCCC CCCC CCCC. After the country code TN and the check digits come a 2-digit bank code, a 3-digit branch code, the 13-digit account number and two national check digits. Tunisia is not a SEPA participant. The currency is the Tunisian dinar (TND). For international payments, routing details, fees and timing depend on the banks, currency and route; check them in advance with your bank. The Tunisian IBAN corresponds to the earlier RIB format and is used throughout domestic payments.

Structural fields are based on the official SWIFT IBAN Registry. The editorial method and validation boundary are documented on our German editorial page (German).

Frequently asked questions

How do I check the length of an IBAN from Tunisia?
Remove spaces and count 24 characters. The first two characters are TN; the remaining positions follow TNkk BBSS SCCC CCCC CCCC CCCC. A different length is formally invalid for this country format.
What do the check digits in a Tunisia IBAN mean?
The two check digits are calculated from the complete IBAN using ISO 7064 MOD-97. They help detect format and transcription errors. A passing checksum does not confirm that an account exists or identify its account holder.
What should I do when an IBAN is formally invalid?
Check the country code, character count, letters and digits, and the check digits. Compare the entry with your bank records or ask the bank for the correct IBAN. This checker validates structure and checksum; it does not verify account ownership or payment approval.
