Telephone numbers in Andorra are six digits, with fixed line numbers beginning with the digits 8 and 7 and mobile telephone numbers with the digits 3 and 6. Toll-free numbers are eight digits, beginning with 1800 (if they are accessible only within Andorra) or 1802 (if they also can be reached internationally). Three-digit numbers starting with 1 are reserved and six-digit numbers starting with 9 are reserved for special services, and nine-digit number starting with 690 are assigned to special mobile services such as machine to machine communications.[1]
Until 1994, Andorra formed part of the French numbering plan, with the prefix 628 being used for calls from France[2] (or 16 628 from Paris) while +33 628 was used from the rest of the world.[3] Access was also possible via the Spanish numbering plan using the area code 9738, or the international prefix +34 738.[4] On 17 December of that year, Andorra adopted its own country code, +376.[5] This meant that all international calls to the Principality, including those from France and Spain, required the use of the +376 country code.[6]
