Andorra uses a closed national numbering plan in which subscriber numbers contain six digits and are reached internationally with the country code +376. The plan is compact and uniform: there are no separate area codes in the sense used by larger countries, and each telephone number is represented by six digits after the country code.
Number structure and common prefixes
National numbers in Andorra always have six digits. Distinct ranges are allocated to fixed and mobile services to help identify the type of line:
- Fixed line numbers commonly begin with the digits 7 and 8.
- Mobile telephone numbers typically start with the digits 3, 4, or 6.
When written in international format a number appears as +376 followed by the six-digit subscriber number (for example, +376 3xxxxx). Within Andorra, callers simply dial the six-digit number.
Dialling conventions and formatting
To call an Andorran number from outside the country, dial the international access code used in the originating country, then +376 and the six-digit national number. Because the national plan is short and flat, there is no separate national trunk prefix that callers must insert before an area code. Local practice may use spacing or grouping to improve readability, but the underlying dialled string remains six digits.
History and development
Before adopting its own country code, Andorra was integrated into the French telephone numbering arrangements. Until 17 December 1994, calls to Andorra were routed using a French prefix (0628). From that date onward Andorra received its own international dialing code, +376, and began operating an independent national numbering plan. That change clarified international routing and emphasized the separate telecom identity of the principality.
Uses and notable points
The compact nature of Andorra's numbering plan makes administration straightforward and makes numbers easy to recognize. Knowing the initial digit provides a quick indication of whether a number is a fixed line or a mobile subscription. For regulatory, business and directory purposes, the six-digit format and the +376 code are the fundamental references for contact information.
