Q: How long is a Tunisia IBAN?

A Tunisia IBAN is 24 characters long.

24-character IBAN · TND Tunisian Dinar

A Tunisia IBAN is 24 characters long and always begins with the country code TN, followed by two check digits. The next 2 characters are the Bank Code. This is followed by the Branch Code (3 characters). The remaining 13 characters identify the individual account number. The Tunisia IBAN uses the TND (Tunisian Dinar) and is not part of the SEPA zone, so international transfer fees and timelines apply.

Tunisia IBAN Regex Pattern

^TN\d{2}\d{2}\d{3}\d{13}\d{2}$

Pattern validates length, country code, check digit positions, and field character types. Does not verify the MOD-97 checksum (use the validator above for full validation).

PHP

$iban = strtoupper(str_replace(' ', '', $input));
if (!preg_match('/^TN\\d{2}\\d{2}\\d{3}\\d{13}\\d{2}$/', $iban)) {
    // Invalid Tunisia IBAN format
}

JavaScript

const iban = input.replace(/\s+/g, '').toUpperCase();
const pattern = /^TN\d{2}\d{2}\d{3}\d{13}\d{2}$/;
if (!pattern.test(iban)) {
  // Invalid Tunisia IBAN format
}

Python

import re
iban = input_str.replace(' ', '').upper()
pattern = r'^TN\d{2}\d{2}\d{3}\d{13}\d{2}$'
if not re.fullmatch(pattern, iban):
    # Invalid Tunisia IBAN format

These snippets check format only. For full IBAN validation including MOD-97 checksum, use a dedicated IBAN library or the validator on this page.

How to Find Your Tunisia IBAN

Tunisia accounts are traditionally identified using: Bank Code (2n) + Branch Code (3n) + Account Number (13c) + Check Digits (2n). Your IBAN encodes these same components in the standardised international format.

1
Mobile banking app — Open your bank's app, navigate to account details or "Account Info." Your IBAN is usually displayed alongside your account number. Look for a field labelled "IBAN" or "International Account Number."
2
Bank statement — Your Tunisia IBAN appears in the account header of your printed or PDF bank statement, typically near the top of the first page.
3
Online banking — Log in to your bank's website and go to "Account Details," "Account Summary," or "Profile." Most Tunisia banks display the IBAN prominently in account settings.
4
Bank branch or helpline — Call your bank's customer service or visit a branch with your ID. They can provide your full IBAN instantly.

Once you have your IBAN, use the validator above to confirm it is correctly formatted before sharing it.

Sending Money to Tunisia

Tunisia is not a SEPA member. Transfers require both an IBAN and a BIC/SWIFT code. Expect 2–5 business days and a SWIFT correspondent fee (typically $10–$40 USD via a traditional bank). Using a specialist service like Wise or Revolut can significantly reduce these fees.
