Area Code 976 – Zaragoza

Geographic Coverage and Administrative Jurisdiction

The +34 976 country-code prefix corresponds to the geographic area code for the province of Zaragoza, located in the autonomous community of Aragon in northeastern Spain. This numbering area encompasses not only the capital city of Zaragoza—the fifth-largest municipality in Spain—but also the surrounding comarcas and smaller towns that fall within the provincial boundaries. The code is administered under Spain's national numbering plan, which follows ITU-T E.164 recommendations. As a geographic prefix, 976 is assigned to fixed-line PSTN and VoIP services that are physically or nominally located within this province.

Primary Cities and Local Dialing

Besides the city of Zaragoza, the 976 area code covers significant towns such as Calatayud, Ejea de los Caballeros, Tarazona, and Utebo, among others. For local calls within the same area code, subscribers can dial the eight-digit subscriber number directly without the trunk prefix or area code. However, for calls originating from outside the 976 area but still within Spain, callers must dial the national trunk prefix '0' followed by the area code and the subscriber number (e.g., 0 976 XXX XXX). This trunk prefix is not part of the international dialing sequence.

International Dialing Format

For international callers, the correct format is +34 976 XXX XXX, where '+34' is the country calling code for Spain, '976' is the national destination code (NDC) for Zaragoza, and the remaining eight digits constitute the local subscriber number. It is essential to drop the leading '0' when dialing from abroad. For example, a local Zaragoza number written as 976 123 456 would be dialed as +34 976 123 456 from any other country.

Numbering and Overlay Considerations

Spain's numbering plan does not use area code overlays in the traditional North American sense; instead, each geographic province maintains a distinct NDC. The 976 area code is not subject to overlay, and all fixed-line numbers within the province share the same length of nine digits (including the leading '0' for national dialing). Mobile numbers in Spain always begin with '6' or '7' and are non-geographic, so they are not affected by this area code.

Caller Instructions

Local callers within Zaragoza can dial the eight-digit number directly. National callers outside the 976 area must dial 0 976 followed by the subscriber number. International callers should use +34 976 and the eight-digit number. When calling from a mobile phone within Spain, it is common practice to include the area code even for local calls, as mobile networks treat all numbers as national. For fixed-line VoIP services, the same dialing rules apply, ensuring seamless routing across the PSTN and IP networks.
