A complete international number is built from four parts. Here's the anatomy and the dialling order.
Number anatomy
Format follows ITU-T Recommendation E.164 the international public telecommunication numbering plan.
Press + on a mobile (hold the 0 key), or dial 00 from most countries / 011 from North America.
Dial +378. This identifies San Marino on the global telephone network.
Type the first part of the local number. Drop the leading 0 if there is one.
The remaining digits route the call to the specific line in San Marino or elsewhere.
To call San Marino on WhatsApp, save the number with +378 and no exit prefix — WhatsApp dials from your contacts, not a dial pad. Voice and video calls are free over data.

TKOS provisions +378 DIDs and termination through direct carrier interconnects.
San Marino holds one of Europe's most unusual telephony arrangements. The republic is a landlocked microstate entirely surrounded by Italy, and its telephone network reflects that geography — many San Marino numbers are simultaneously reachable via the Italian country code +39 with the area prefix 0549, a legacy of the shared infrastructure that predates San Marino's dedicated +378 code. When dialling from outside Europe the correct modern format is +378 followed by the full 10-digit local number without any leading zero. Unlike most European neighbours, San Marino's number range is not split by city area codes: all subscriber lines fall under a single national block. The republic shares Central European Time (CET, UTC+1) with Italy and switches to CEST (UTC+2) each summer following EU daylight-saving rules. Emergency calls reach 113 for police, 118 for medical, and 115 for fire — each a separate service rather than a single unified number.
Whether you're reaching San Marino for business or family, three habits keep every conversation crystal clear and a clean route from TKOS handles the rest.
San Marino routes support G.722 wideband audio on EU-peered carriers — an HD headset makes the quality difference immediately obvious on these low-latency links.
San Marino is ~7,924 km away — expect ~280ms round-trip. A wired ethernet connection keeps packet loss below 0.1%.
Schedule San Marino calls during San Marino business hours — 09:00–17:00 Europe/San_Marino — your contact will be at their desk in a quiet space rather than taking the call on the move.
