📍 Geographic Location of Skikda
Geographic Overview
The +213 39 prefix is the National Destination Code (NDC) for the wilaya of Skikda, a province in northeastern Algeria. Skikda is a major Mediterranean port city and an industrial hub, known for its petrochemical plants and scenic coastline. The code covers the city of Skikda itself and the surrounding municipalities within the province, including El Harrouch, Azzaba, and Tamalous. As a geographic code, it is tied to a specific administrative region, and calls to numbers with this prefix are routed to fixed-line subscribers within that area.
Dialing Formats
When calling a Skikda landline from within Algeria, you must dial the trunk prefix 0 followed by the NDC and the subscriber number. For example, a local number might be formatted as 039 XX XX XX (with the leading 0). From outside Algeria, you would dial the international access code (e.g., 00 from most countries), then Algeria's country code +213, followed by the NDC 39 and the subscriber number, omitting the leading 0. Thus, the international format becomes +213 39 XX XX XX.
Caller Instructions
For local callers within Algeria: If you are calling from another wilaya, you must use the full national format: 039 XX XX XX. If you are calling from within Skikda itself, you may be able to dial just the subscriber number (7 digits) depending on the local network configuration, but using the full national number is always safe.
For international callers: Replace the leading 0 with +213, so dial +213 39 XX XX XX. Ensure you have the correct international exit code for your country (e.g., 011 from the US, 00 from most European countries).
Numbering and Overlays
Algeria's numbering plan follows ITU-T E.164 recommendations. Subscriber numbers within the 39 NDC are typically 7 digits long, making the total national significant number (NSN) 9 digits (including the NDC). There are no overlay codes currently assigned to Skikda; the 39 code is exclusively for this region. However, as Algeria expands its fixed-line network, some areas may see new codes introduced, so it is always advisable to verify the number with the called party if you encounter issues.
Technical Considerations
All fixed-line numbers in Algeria are allocated to the incumbent operator Algérie Télécom. Calls to these numbers are routed over the PSTN and are subject to standard national and international tariffs. VoIP services may also use these numbers, but the geographic association remains for regulatory and emergency services purposes. When storing numbers in your contacts, always use the international format +213 39 XX XX XX to ensure proper dialing from any location.
