IBAN Structure San Marino

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

San Marino's IBAN has 27 characters in the format SMkk XBBB BBGG GGGC CCCC CCCC CCC — structurally identical to the Italian IBAN. After the country code SM and the IBAN check digits come a single national check character (CIN), the 5-digit ABI bank code, the 5-digit CAB branch code and the 12-character account number. San Marino uses the euro under a monetary agreement with the EU without being an EU member. The republic takes part in SEPA, so euro transfers go through as ordinary SEPA payments — no BIC, no extra fee, at the same rate as a domestic transfer.
