Mauritius SWIFT/BIC code validator
How the SWIFT/BIC code format works
- Format
- 8 or 11-character bank identifier code, country code MU in positions 5-6
- Example
- MCBLMUMU
Things to watch for
- Structure: 4-letter bank code + MU (country) + 2-character location code, plus an optional 3-character branch code
- Mauritius's major banks happen to repeat MU as the location code too, so the letters MU can appear twice in the same 8-character BIC
- No checksum digit — this is a format check only; it confirms positions 5-6 read MU, not that the bank or branch actually exists
^[A-Z]{4}MU[A-Z0-9]{2}([A-Z0-9]{3})?$A Mauritian SWIFT/BIC code identifies the bank on an international wire transfer into or out of Mauritius, working alongside the domestic Mauritian IBAN that identifies the account itself — Mauritius is one of the few countries outside Europe and the Middle East on the official IBAN registry. Every Mauritian BIC has MU fixed at positions 5-6, right after the 4-letter bank code, and the country’s two largest banks both use MU again as the location code, so MUMU appears at the end of their 8-character codes.
Major Mauritian bank BIC prefixes
| Bank | BIC | Location |
|---|---|---|
| Mauritius Commercial Bank (MCB) | MCBLMUMU | Port Louis |
| State Bank of Mauritius (SBM) | STCBMUMU | Port Louis |
How this validator works
This tool checks that the code is 8 or 11 characters, the first 4 characters are letters, positions 5-6 read MU, and the location and optional branch segments use only letters and digits — entirely client-side, with nothing sent to a server.
What a pass doesn’t tell you
A pass confirms the code fits the Mauritian BIC pattern, not that MCBL or STCB still names an operating bank, or that the branch suffix is current. A BIC carries no checksum digit, so a fabricated code that matches the shape still validates.
Scope: format validation only. A correctly formatted BIC says nothing about whether the accompanying Mauritian IBAN entered on the same form is valid.
SWIFT/BIC code FAQ
What's the SWIFT code format for a Mauritian bank?
A Mauritian BIC is 8 or 11 characters: a 4-letter bank code, MU fixed at positions 5-6, a 2-character location code, and an optional 3-character branch code — for example MCBLMUMU for the Mauritius Commercial Bank.
Why does MU appear twice in a Mauritian BIC?
The country code (positions 5-6) and the location code (positions 7-8) are assigned independently, and for Mauritius's largest banks both happen to read MU — one for the country, one for the registered financial centre — so the letters repeat by coincidence, not by rule.
Does an 8-character code work for a Mauritian bank?
Yes — the 8-character BIC and its 11-character form ending XXX both identify the same head office and are accepted interchangeably on wire instructions.
