Notes on San Marino Dialing
San Marino has its own country code, +378, assigned by the International Telecommunication Union (ITU). While it historically shared Italy's numbering plan (using +39 0549), it now operates independently.
All numbers are short (typically 6-7 digits after +378). Mobile numbers often start with 6, and landlines with 8.
When calling from abroad, dial: +378 [6-7-digit number].
Example: +378 888 1234 (landline) or +378 666 5432 (mobile)
