Area Code 845 – Araba

Overview of Area Code 845 (Araba, Spain)

Area code 845 is a geographic National Destination Code (NDC) assigned to the province of Araba/Álava, located in the Basque Country (País Vasco) in northern Spain. This code is part of the Spanish national numbering plan, which is administered by the Comisión Nacional de los Mercados y la Competencia (CNMC) in accordance with ITU-T E.164 recommendations. The 845 code covers the provincial capital, Vitoria-Gasteiz, as well as surrounding municipalities and rural areas within Araba.

Geographic Coverage and Administrative Jurisdiction

The 845 area code serves the entire province of Araba, which is one of the three provinces that constitute the autonomous community of the Basque Country. The primary city is Vitoria-Gasteiz, which is also the seat of the Basque Government and the Parliament. Other notable towns and localities within this code include Llodio (Laudio), Amurrio, Salvatierra (Agurain), and Ayala (Aiara). The province borders the provinces of Bizkaia, Gipuzkoa, Navarra, and La Rioja, and also shares a short border with France.

Dialing Formats and Caller Instructions

For callers within Spain, the national dialing format for a fixed-line number in Araba is 845 XX XX XX (or 845 XXX XXX, depending on the number length). The leading '8' is part of the NDC and must be dialed even when calling from a local number within the same area code. For international callers, the full international format is +34 845 XX XX XX, where +34 is the country calling code for Spain. When calling from abroad, the leading '0' (if any) is omitted, but in Spain, there is no trunk prefix '0' for domestic calls; the NDC is always dialed as part of the number.

Overlay and Numbering Plan Considerations

Currently, there is no overlay code for Araba; the 845 code is the sole geographic code for the province. However, due to the increasing demand for telecommunication services, the CNMC has implemented measures to ensure sufficient numbering resources, including the possibility of future overlays. In such cases, ten-digit dialing (including the NDC) would become mandatory for all local calls. As of now, callers within the same area code must still dial the full number, including the 845 prefix, because the Spanish numbering plan requires it for all calls, even local ones.

Services and Usage

Numbers under the 845 code are primarily used for fixed-line PSTN and VoIP services. Businesses and residents in Araba use these numbers for voice, fax, and data services. The code is also used by some mobile operators for fixed-wireless access, but it is fundamentally a geographic code. When calling a Spanish fixed-line number from abroad, it is essential to use the correct international prefix (e.g., 00 from most countries) followed by 34 and the full national number, including the 845 area code.
