IBAN Structure Mauritania

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

Mauritania's IBAN has 27 characters in the format MRkk BBBB BBBB BBBB BBBB BBBB BBB. After the country code MR and the check digits come a 5-digit bank code, a 5-digit branch code, the 11-digit account number and two national check digits. Mauritania is not a SEPA participant. The currency is the ouguiya (MRU). For international payments, routing details, fees and timing depend on the banks, currency and route; check them in advance with your bank. The IBAN layout follows the French RIB scheme, with a national check key at the end.

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 Mauritania?
Remove spaces and count 27 characters. The first two characters are MR; the remaining positions follow MRkk BBBB BBBB BBBB BBBB BBBB BBB. A different length is formally invalid for this country format.
What do the check digits in a Mauritania 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.
