About San Marino Calling Code
Every country has a unique international dialing prefix; for San Marino it is +378. The ITU assigns these codes under recommendation E.164. Dial +378 after your country's exit code, then the local subscriber number. San Marino is in Europe.
The ITU-T E.164 recommendation standardizes international numbering, giving every country and territory a distinct prefix. Without the correct prefix, international calls cannot be routed to the right destination.
