Area Code 1121 – Addis Ababa

Overview of Area Code 1121

Area code 1121 is a geographic National Destination Code (NDC) assigned to the central part of Addis Ababa, the capital and largest city of the Federal Democratic Republic of Ethiopia. As part of the Ethiopian numbering plan, this code falls under the +251 country calling code, which is administered by the Ethiopian Communications Authority (ECA). The 1121 prefix is used for fixed-line (PSTN) services, and it is primarily associated with the administrative, commercial, and diplomatic districts of the city, including areas around the African Union headquarters, Meskel Square, and the Bole district.

Geographic Coverage and Jurisdiction

Addis Ababa is a chartered city with its own administrative jurisdiction, distinct from the surrounding Oromia Special Zone. The 1121 code specifically serves the central business district and adjacent neighborhoods, where many government ministries, embassies, and corporate headquarters are located. This geographic allocation means that the code is tied to a physical location, and calls to 1121 numbers are routed to the corresponding exchange in Addis Ababa.

Dialing Formats and Instructions

For callers within Ethiopia, the national dialing format is 011211XXXX, where the leading '0' is the trunk prefix, '11' is the area code for Addis Ababa, and '21' is the exchange code, followed by the subscriber number (typically 4 digits). For example, a local call to a number would be dialed as 0112112345.

For international callers, the format is +251 1121 XXXX (or +2511121XXXX without spaces). The leading '0' is omitted when dialing from abroad. Thus, the same number would be dialed as +25111212345 from outside Ethiopia.

It is important to note that Ethiopia does not currently use area code overlays for Addis Ababa; the city is served by a single area code '11', with various exchange prefixes like 1121. Therefore, local calls within Addis Ababa do not require an additional area code if dialing from another fixed-line in the same city, but the full national format is recommended for clarity.

Caller Instructions

Local callers within Ethiopia should always include the trunk prefix '0' when dialing any fixed-line number outside their local exchange. For example, a caller in Addis Ababa dialing another Addis Ababa number may omit the area code if the exchange is the same, but using the full national format ensures correct routing. Foreign callers must replace the trunk prefix with the Ethiopian country code +251 and drop the leading '0'. For instance, a caller from the United States would dial 011 251 1121 XXXX (using the US international exit code 011), while a caller from the UK would dial 00 251 1121 XXXX.

Considerations for Businesses and Residents

Businesses and residents with 1121 numbers benefit from the prestige and central location of Addis Ababa. However, as with all geographic numbers, the physical location of the line is fixed, and moving outside the 1121 serving area may require a number change. For VoIP or mobile services, non-geographic numbers are used instead. When calling 1121 numbers, standard international tariffs apply, and callers should check with their service provider for any special rates to Ethiopia.
