Area Code 1124 – Addis Ababa

Overview of Area Code 1124 (Addis Ababa)

Area code 1124 is a geographic National Destination Code (NDC) assigned to the Addis Ababa region in Ethiopia. It is part of the country's national numbering plan, which follows the ITU-T E.164 recommendation. The full international dialing format for a subscriber number in this area is +251 1124 XXX XX, where +251 is the country calling code for Ethiopia, 1124 is the NDC, and the remaining digits constitute the subscriber number. In the national (domestic) format, the leading '0' is used: 01124 XXX XX.

Geographic Coverage and Administrative Jurisdiction

The 1124 code serves the Addis Ababa administrative area, which is a chartered city and the capital of Ethiopia. It covers the central business district, government offices, embassies, and residential neighborhoods. As a geographic code, it is tied to a specific physical location, and the number is typically associated with fixed-line PSTN services, though some VoIP operators may also use it for local presence.

Dialing Formats and Caller Instructions

For callers within Ethiopia, dial the national trunk prefix 0, followed by the NDC and subscriber number: 01124 XXX XX. For international callers, dial your country's exit code (e.g., 00 or +), then Ethiopia's country code 251, then the NDC without the leading '0', and the subscriber number: +251 1124 XXX XX. For example, a local call to a number in Addis Ababa might be 01124 123 45, while an international caller would dial +251 1124 123 45.

Numbering Plan and Overlay Considerations

Ethiopia's numbering plan is administered by the Ethiopian Communications Authority (ECA). The NDC 1124 is part of a larger block for Addis Ababa, which includes other codes like 111, 112, 113, etc. There are no overlay codes for this area; each geographic region has a unique NDC. Subscriber numbers within the 1124 block are typically 7 digits long, making the total national number length 10 digits (including the trunk prefix).

Practical Usage and Migration

While mobile numbers in Ethiopia are non-geographic and start with 9 (e.g., +251 9XX XXX XXX), fixed-line numbers like those under 1124 are used for businesses, government offices, and households. With the growth of VoIP and mobile services, the use of geographic codes is evolving, but 1124 remains a reliable identifier for Addis Ababa landlines. When calling from abroad, ensure you have the correct country code and NDC to avoid misdialing.
