Area Code 971 – Balearic Islands

Geographic Coverage and Administrative Scope

The +34 971 country code prefix is the geographic National Destination Code (NDC) assigned to the Balearic Islands, an autonomous community of Spain located in the Mediterranean Sea. This code covers the entire archipelago, including the four main inhabited islands: Mallorca (with the capital Palma), Menorca, Ibiza, and Formentera. Smaller islands such as Cabrera are also included within this numbering area. The prefix 971 is used for fixed-line telephone services (PSTN) and is administered by the Spanish telecommunications regulator, the Comisión Nacional de los Mercados y la Competencia (CNMC).

Dialing Formats and Caller Instructions

For local callers within the Balearic Islands, the full nine-digit national significant number (NSN) must be dialed, which includes the area code 971 followed by the subscriber's seven-digit local number. For example, a fixed line in Palma would be dialed as 971 12 34 56. Since the implementation of the Spanish Numbering Plan, all geographic numbers in Spain require the area code to be dialed even for local calls; there is no shorter local format. For international callers, the number must be prefixed with the international access code (00 or +) followed by Spain's country code 34 and then the NSN: +34 971 12 34 56. When calling from a mobile phone, the plus sign (+) is typically used: +34 971 12 34 56.

Numbering and Overlay Considerations

Currently, there is no overlay code for the Balearic Islands; the 971 code is the sole geographic area code for the region. However, due to the increasing demand for fixed-line services, the CNMC has reserved the prefix 871 as a potential overlay for future use. If an overlay is introduced, ten-digit dialing (including the area code) would become mandatory for all local calls, but as of now, nine-digit dialing remains the standard. Subscriber numbers within the 971 code are typically seven digits long, but some older numbers may have fewer digits, in which case they are padded with leading zeros to reach the seven-digit format.

Practical Information for Callers

When calling a Balearic fixed line from outside Spain, you must replace the trunk prefix (0) with the international access code and Spain's country code. For example, to call a number in Ibiza from the United States, you would dial 011 34 971 XX XX XX. From a mobile phone, simply use +34 971 XX XX XX. It is important to note that calls to 971 numbers are charged according to the caller's national or international tariff, and there are no special premium rates associated with this geographic code. For businesses or individuals establishing a presence in the Balearic Islands, obtaining a 971 number is essential for local credibility and to ensure that customers can reach them at local call rates.
