Tunisia IBAN Format & Validator (TN)

Tunisia IBAN — Complete Banking Guide

The International Bank Account Number (IBAN) system is used in Tunisia to uniquely identify bank accounts for domestic and international transfers. Every bank account in Tunisia is assigned a 24-character IBAN that begins with the country code TN, followed by two mathematically calculated check digits, and then the local BBAN (Basic Bank Account Number) encoding 2 digits bank, 3 digits branch, 13 digits account, 2 check. The IBAN standard in Tunisia is governed by ISO 13616 and administered through the SWIFT IBAN registry.

Unlike domestic account numbers which vary in format between banks, an IBAN provides a standardised, universally recognised account identifier. Any bank in the world that participates in the SWIFT network can process a payment to a Tunisia IBAN without requiring additional routing information — the bank code and branch information is encoded directly in the IBAN itself.

International Transfers to Tunisia — What You Need

Tunisia is not a SEPA member, which means standard international wire transfer rules apply. When sending money to a Tunisia bank account, you will need the following information:

• Tunisia IBAN — 24 characters, starting with TN
• SWIFT/BIC code of the receiving Tunisia bank — find it on BankZop's SWIFT Code Lookup
• Beneficiary's full name as registered with their bank
• Bank name and address — required by many sending banks for compliance
• Transfer purpose — required for RBI compliance when sending from India (family remittance, education fee, business payment, etc.)

International wire transfers to Tunisia typically take 1–5 business days depending on the correspondent banking chain and any currency conversion required. Always verify the IBAN with the recipient before initiating a transfer — an incorrect IBAN will cause the payment to be rejected, and some banks charge fees for returned wires.

How to Read a Tunisia IBAN — Digit by Digit

The 24-character Tunisia IBAN is structured as follows: TNkk BBSS SCCC CCCC CCCC CCCC

• Positions 1–2 (TN): ISO 3166-1 country code for Tunisia. This is always fixed and cannot change.
• Positions 3–4 (kk): Two numeric check digits calculated using the ISO 7064 modulo-97 algorithm. These verify the entire IBAN is correctly formed.
• Positions 5–24 (BBAN): The Tunisia-specific BBAN (Basic Bank Account Number): 2 digits bank, 3 digits branch, 13 digits account, 2 check. This part encodes the bank, branch, and account number according to Tunisia's national banking standards.

For example: TN59 1000 6035 1835 9847 8831 is a structurally valid Tunisia IBAN. When you paste any Tunisia IBAN into the validator above and click Validate IBAN, BankZop instantly verifies the check digits using the modulo-97 algorithm — no internet connection required for the validation itself.

Finding Your Tunisia IBAN

Your Tunisia IBAN can be found in several places. The most reliable sources are:

1. Mobile or online banking app: Log in and navigate to Account Details or Account Summary. The IBAN is displayed alongside your account number and sort code.
2. Bank statement: Your monthly bank statement — whether paper or PDF — includes the IBAN in the account summary header, typically on the first page.
3. Cheque book: Some Tunisia banks print the IBAN on the front page of the cheque book or inside the cover.
4. Bank counter or customer service: Call the number on the back of your debit card and ask for your full IBAN. You will need to verify your identity.
5. Welcome letter: When an account is first opened, banks typically send a welcome letter containing the IBAN and account details.

Once you have your IBAN, share it with anyone who needs to send you money from abroad. Never share your full IBAN publicly, but it is safe to share it with people or businesses you trust for legitimate payment purposes — an IBAN alone cannot be used to withdraw money from your account.

Common Tunisia IBAN Errors to Avoid

• Wrong character count: A Tunisia IBAN must be exactly 24 characters. Count carefully — even one extra or missing character will fail validation.
• Confusing IBAN with account number: Your IBAN is different from your local account number. The account number appears inside the IBAN but the two codes are not interchangeable.
• Spaces in the IBAN: IBANs are sometimes written with spaces for readability (e.g. TN59 1000 6035 1835 9847 8831), but when entering an IBAN in a bank form, always remove all spaces. BankZop's validator accepts both formats.
• Using IBAN for domestic transfers: Within Tunisia, some banks still use local account numbers for domestic transfers. Check with your bank whether IBAN is required or optional for domestic payments.
• Wrong country IBAN: Never use an IBAN from one country for an account in another country. The TN prefix specifically identifies this as a Tunisia account.

Banking Codes for Tunisia — Quick Reference

When dealing with Tunisia bank transactions, you may encounter several different banking codes depending on the payment type:

• IBAN (this page): 24-character code for international and cross-border transfers. Format: TNkk...
• SWIFT/BIC Code: 8 or 11 characters identifying the specific Tunisia bank. Required for all international wires.
• Local account number: Country-specific format used for domestic payments within Tunisia.

For sending money to India from Tunisia, the recipient's Indian bank will need their IFSC code (for domestic India transfers) or the bank's SWIFT code (for the international leg of the transfer).
