Mauritius IBAN validator

A Mauritius IBAN is 30 characters: “MU”, two check digits, a 4-letter bank code, 19 digits covering branch and account, and a 3-letter currency code at the very end — MUR in the example MU17BOMM0101101030300200000MUR, though the same account block format could just as easily close with USD or EUR. That trailing currency code exists because Mauritius’s banking sector is a well-established offshore and international financial services hub, where a single bank and branch commonly hold multi-currency accounts for the same client — the currency code is what lets an IBAN identify which currency a particular account is denominated in, rather than assuming everything routes through the Mauritian rupee. The Bank of Mauritius oversees the system; anyone paying into or receiving funds from a Mauritius-based account needs the full 30-character string, currency suffix included.

How this validator works

This tool checks the “MU” prefix, confirms the bank code is 4 letters, the combined branch/account block is exactly 19 digits, and the trailing currency code is 3 letters, then runs the mod-97 checksum (ISO 7064) a correctly generated Mauritius IBAN must satisfy — entirely in your browser, with nothing sent to a server.

What a pass doesn’t tell you

A pass confirms the 30 characters are correctly structured and internally consistent — not that the account is open, active, or belongs to whoever you expect. This tool does no lookup against the Bank of Mauritius or any commercial bank there. If a Mauritius IBAN fails, double-check the trailing 3-letter currency code first — it’s easy to omit or mistype when an IBAN is copied from a document that only lists the numeric part.

Scope: Mauritius IBAN structure and mod-97 checksum validation only — not payment processing or confirmation an account is active. Catch the typo here; confirm the account with the bank.
