Area Code: none Subscriber Number: 10-12 digits (see note below) Trunk Prefix: n/a International Prefix: 00Note: Some confusion over inclusion of '0549' for the incoming number; some refereces suggest 6-8 digits suffice for inbound calls.
However, official information from carrier Telecom Italia indicates that both formats are valid for calls into San Marino, as indicated on their information page for calling to San Marino (in Italian).
Italy makes calls to San Marino as if this were a domestic call i.e. 0549 followed by San Marino number, and not using 00378 (international prefix + 378).
(additional input from Chris Ward, Alan Burkitt-Gray)
Mobile range +378 3 xxxxxxxx... was identifed for future use. These will have 9 to 12 digits excluding the country code.
See Intelcom San Marino S.p.A. announcement (6 April 2005, via ITU).
Subscriber numbers beginning with the digit '3' were expanded to 12 digits. The special purpose of these numbers, if any, is unknown, although this range is associated with mobile numbers in Italy, which surrounds San Marino.
A permissive dialling period was in effect until 31 December 1998.

San Marino's format is also described in an article on telephone numbering in ScienceDaily and Wikipedia.
ITU assigned +378 as a stand-alone country code. Italy still accessed San Marino through the domestic 0549 area code, but other nations would now use +378 for San Marino.
