📍 Geographic Location of Tlemcen
Geographic Overview
The +213 43 dialing prefix is the National Destination Code (NDC) assigned to the wilaya (province) of Tlemcen in northwestern Algeria. This geographic area code covers the administrative capital Tlemcen city and its surrounding municipalities, including major towns such as Maghnia, Ghazaouet, Remchi, and Mansourah. The region borders Morocco to the west and the Mediterranean Sea to the north, making it a key commercial and cultural hub.
Dialing Formats
When calling a fixed-line number in Tlemcen from within Algeria, subscribers must dial the trunk prefix 0 followed by the area code 43 and the subscriber's 7-digit local number. The complete national format is: 0 43 XX XX XX (e.g., 0 43 12 34 56). For international callers, the country code +213 replaces the leading 0, resulting in the international format: +213 43 XX XX XX (e.g., +213 43 12 34 56).
Caller Instructions
- Local callers (within Tlemcen): If your phone line is provisioned within the same exchange area, you may be able to dial only the 7-digit subscriber number (XX XX XX). However, due to network modernization, it is recommended to always use the full national format (0 43 XX XX XX) to avoid misrouting.
- National callers (outside Tlemcen): Dial 0 43 XX XX XX from any fixed or mobile line in Algeria.
- International callers: Dial your country's exit code (e.g., 00 from most countries, 011 from the US/Canada), then 213 43 XX XX XX. Do not include the leading 0.
Technical Considerations
This prefix is used exclusively for fixed-line (PSTN) services, including traditional copper lines and some fixed wireless terminals. As of recent numbering plan updates, there are no overlay codes for Tlemcen; the 43 NDC remains unique to the province. Mobile numbers in Algeria are assigned separate non-geographic prefixes (e.g., 05, 06, 07) and are not affected by this geographic code. When dialing from abroad, ensure you have the correct country code (+213) and omit the trunk prefix '0'. For VoIP users, the same international format applies, but be aware that some VoIP providers may require a different exit code.
Administrative and Regulatory Notes
The Algerian Post and Electronic Communications Regulatory Authority (ARPCE) manages the national numbering plan. Number portability is available for fixed lines within the same geographic area, meaning a subscriber may retain their number if they change operators within Tlemcen. However, geographic numbers cannot be ported to other regions. For accurate billing and routing, always verify the complete number with the recipient.
