Area Code 1142 – Addis Ababa

Overview of Area Code 1142 (Addis Ababa)

Area code 1142 is a geographic National Destination Code (NDC) assigned to the Addis Ababa metropolitan region in Ethiopia. As part of the Ethiopian numbering plan, which follows ITU-T E.164 recommendations, this code is used for fixed-line (PSTN) services within the capital city. The code is administered by the Ethiopian Communications Authority (ECA) and is currently allocated to Ethio Telecom, the incumbent operator, which provides the majority of fixed-line services in the country.

Geographic Coverage and Dialing Formats

The 1142 code covers the central and surrounding districts of Addis Ababa, including the city's administrative zones and key business areas. It is important to note that Addis Ababa is both a city and a chartered city, serving as the seat of the African Union and the United Nations Economic Commission for Africa. The code is used for fixed-line connections, and its geographic nature means that the tariff and routing are based on the physical location of the line.

For local callers within Addis Ababa, the number is typically dialed as an 8-digit subscriber number, omitting the trunk prefix and area code. For example, a local number might be 1142 1234 (8 digits). However, when calling from outside the area code but within Ethiopia, the full national format is used: 0 1142 1234, where the leading '0' is the trunk prefix. For international callers, the format is +251 1142 1234, replacing the trunk prefix with the country code +251.

Overlay and Numbering Considerations

Addis Ababa has experienced significant demand for fixed-line services, leading to the introduction of overlay codes to supplement the original 11 area code. However, as of the current numbering plan, 1142 remains a distinct code, and no overlay is in effect for this specific prefix. Subscriber numbers under 1142 are typically 8 digits long, including the NDC, but the total number length for geographic numbers in Ethiopia is 9 digits (including the leading '0' when dialed nationally).

It is crucial for callers to understand that the leading '0' is only used for national dialing; it is not part of the international number. Therefore, when dialing from abroad, the number should be entered as +251 1142 1234, without the '0'. This distinction is a common source of dialing errors for international callers.

Caller Instructions and Practical Examples

• Local call (within Addis Ababa): Dial 1142 1234 (assuming the subscriber number is 1142 1234).
• National call (from outside Addis Ababa, e.g., from Dire Dawa): Dial 0 1142 1234.
• International call (from any country): Dial +251 1142 1234 (or the international exit code of your country, then 251 1142 1234).

For businesses and residents in Addis Ababa, the 1142 code is a reliable indicator of a fixed-line connection, which may be important for verifying the legitimacy of a business or for determining the appropriate tariff when calling. As Ethiopia continues to modernize its telecommunications infrastructure, including the rollout of VoIP and mobile services, the geographic nature of 1142 remains unchanged, and it continues to serve as a cornerstone of the capital's communication network.
