Area Code 37 – Tebessa

Geographic Overview

The +213 37 prefix is the National Destination Code (NDC) for the wilaya of Tébessa, a province in northeastern Algeria bordering Tunisia. The region is an important administrative and economic hub, with the city of Tébessa serving as the provincial capital. This geographic code is allocated for fixed-line telephone services within the PSTN (Public Switched Telephone Network).

Dialing Formats

To call a fixed line in Tébessa from within Algeria, subscribers must dial the trunk prefix 0, followed by the NDC 37, and then the subscriber's 6-digit local number. The complete national format is: 0 37 XX XX XX (10 digits total).

For international callers, the country code +213 replaces the leading 0. The international format is: +213 37 XX XX XX (9 digits after the +).

Example Call Scenarios

• Local call (within Tébessa): Dial 0 37 XX XX XX.
• National call (from Algiers or another wilaya): Dial 0 37 XX XX XX.
• International call (from abroad): Dial your country's exit code (e.g., 00 from most European countries, 011 from the US/Canada), then 213 37 XX XX XX.

Important Considerations

Algeria's numbering plan is closed, meaning the trunk prefix 0 is always dialed for domestic calls, even when calling from a mobile phone. The 37 code is strictly geographic and does not cover mobile services; mobile numbers in Algeria begin with 05, 06, or 07. As of the latest ITU-T recommendations, no overlay code has been assigned for Tébessa, so the 37 prefix remains the sole fixed-line code for the region.

When dialing from abroad, it is essential to omit the leading 0 and use the country code +213 instead. The plus sign represents the international access code, which varies by country. Ensure you have the correct international exit code before dialing.
