📍 Geographic Location of Ghardaia/Illizi/Tamanrasset
Geographic Coverage and Administrative Jurisdiction
The +213 29 prefix is a geographic National Destination Code (NDC) assigned to the southern Algerian provinces of Ghardaïa, Illizi, and Tamanrasset. These wilayas (provinces) are administered by the Ministry of Post and Telecommunications (Ministère de la Poste et des Télécommunications) and are served by the state-owned incumbent operator, Algérie Télécom, for fixed-line PSTN services. The code covers both urban centers and remote Saharan communities, including the provincial capitals of Ghardaïa, Illizi, and Tamanrasset, as well as smaller settlements within these vast territories.
Dialing Formats and Number Structure
When dialing within Algeria, subscribers must use the full 9-digit national significant number (NSN), which includes the leading '0' trunk prefix followed by the area code and the subscriber number. For example, a local call to Ghardaïa would be dialed as 029 XX XX XX. The subscriber number is typically 6 digits long, making the complete national format 0 29 XX XX XX.
For international callers, the format is +213 29 XX XX XX, where the leading '0' is omitted. The country calling code for Algeria is +213, and the '29' is the geographic area code. When calling from a mobile phone, the same international format applies, and the plus sign (+) indicates the international access code.
Overlay and Numbering Plan Considerations
Currently, there is no overlay code for the 29 region; the numbering plan is closed, and all fixed-line numbers within the area share the same 9-digit structure. However, due to the vast geographic area and low population density, number portability is not widely implemented for fixed lines. Subscribers in remote areas may experience routing delays, but the network infrastructure is continuously being upgraded to support VoIP and fiber-optic connectivity.
Caller Instructions
- Local callers (within Algeria): Dial the full national number: 029 XX XX XX.
- International callers: Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 213 29 XX XX XX. Alternatively, use the plus sign: +213 29 XX XX XX.
- Calling from a mobile phone: Use the international format +213 29 XX XX XX to ensure proper routing.
Note that while the region is vast, the numbering plan is unified, meaning there are no additional local area codes within the 29 zone. All fixed-line numbers in Ghardaïa, Illizi, and Tamanrasset share the same prefix, simplifying dialing for both domestic and international callers.
