Convert Monaco IBANs to their BIC
Every Monaco IBAN is 27 characters long and starts with MC. The bank identifier embedded inside it is what resolves to a BIC/SWIFT code, the bank's name and address, and its SEPA reachability.
The Monaco IBAN format
Example of a valid Monaco IBAN:
MC58 1122 2000 0101 2345 6789 030
| Segment | Length | Example | Meaning |
|---|---|---|---|
| Country code | 2 | MC | Always MC |
| Check digits | 2 | 58 | ISO 7064 mod-97 checksum over the whole IBAN |
| Bank code | 5 | 11222 | Numeric code identifying the Monegasque bank |
| Branch code | 5 | 00001 | Numeric code identifying the branch |
| Account number | 11 | 01234567890 | Alphanumeric account identifier |
| RIB key | 2 | 30 | National checksum, as in the French RIB system |
Monaco is not an EU member but uses the euro and the French RIB account structure — MC IBANs look exactly like French ones apart from the country code.
How to get the BIC from a Monaco IBAN
Validate the IBAN
Check the length (exactly 27 characters for MC) and the ISO 7064 mod-97 checksum. Both are local computations — no lookup needed yet.
Extract the bank identifier
The bank code (5 characters) inside the BBAN identifies the institution holding the account.
Resolve it to a BIC
Map the bank identifier to the institution's BIC via registry data — or send the IBAN to the API and get BIC, bank details and SEPA flags in one response.
Resolve it with one API call
Send the IBAN to POST /v1/convert and get back the BIC, bank details and the four SEPA reachability flags. Invalid and not-found lookups are always free.
