Area Code 28 – Algiers

Overview of Algeria's +213 28 Geographic Prefix

The +213 28 prefix is a geographic National Destination Code (NDC) assigned to the wilaya of Algiers, the capital and largest city of Algeria. It covers the central metropolitan area, including the administrative, commercial, and historical districts. As a geographic code, it is tied to the PSTN infrastructure of Algiers, serving both fixed-line residential and business subscribers. The prefix is managed by the Algerian Post and Electronic Communications Authority (ARPCE) and is utilized by the incumbent operator Algérie Télécom for landline services.

Geographic Coverage and Administrative Jurisdiction

The 28 code encompasses the entire wilaya of Algiers, which is subdivided into multiple districts (dairas) and municipalities. Key areas served include the city center (Alger Centre), Bab El Oued, El Harrach, Kouba, Hydra, and the diplomatic quarter. The coverage extends to the surrounding urban and peri-urban zones, reflecting the dense population and economic importance of the capital. It is important to note that the prefix is not used for mobile services; mobile numbers in Algeria begin with 05, 06, or 07 under the +213 country code.

Dialing Formats and Instructions

For callers within Algeria, the national format requires dialing the trunk prefix '0' followed by the NDC and the subscriber number. For a fixed line in Algiers, the number is typically 8 digits long after the NDC, but the full national format is: 0 28 XX XX XX XX (10 digits total). For example, a local Algiers number might be 0 28 45 67 89 10.

For international callers, the format is: +213 28 XX XX XX XX (or 00213 28 ... from many countries). The leading '0' is dropped when dialing from abroad. For instance, to call the same number from outside Algeria, you would dial +213 28 45 67 89 10.

When dialing locally within Algiers, it is still necessary to include the full national number, as there are no local area code omissions. Overlay codes are not in effect; the 28 prefix is exclusive to Algiers, and no other geographic code shares the same area.

Practical Considerations for Callers

For local callers within Algeria, calls to 28 numbers are typically charged at standard fixed-line rates. For international callers, charges depend on their carrier and the international tariff. It is advisable to check with your service provider for specific rates. If you are calling from a mobile phone within Algeria, you must still include the '0' before the 28. For VoIP users, ensure you have international dialing enabled and use the +213 format.

In summary, the +213 28 prefix is a reliable indicator of a fixed-line connection in Algiers, and understanding the correct dialing format ensures seamless connectivity with businesses and residents in Algeria's capital.
