Area Code 2120 – Hajigabul

Overview of Azerbaijan's Geographic Numbering Plan

Azerbaijan's national numbering plan adheres to the ITU-T E.164 recommendation, with country calling code +994. Geographic numbers are allocated to fixed-line services and are identified by a two-digit National Destination Code (NDC) that corresponds to a specific administrative region or city. The prefix 2120 is part of the NDC 212, which is assigned to the Hajigabul District. This prefix is used for fixed-line telephone services within the district, connecting subscribers to the PSTN.

Geographic Coverage and Administrative Jurisdiction

Hajigabul is an administrative district in the eastern part of Azerbaijan, situated along the Kura River. The district's administrative center is the city of Hajigabul, which is the primary locality served by the 2120 prefix. The district is known for its agricultural activities and its strategic location along major transport routes. The prefix covers the city and its surrounding rural settlements, providing fixed-line connectivity to residential, commercial, and governmental subscribers.

Dialing Formats and Caller Instructions

For callers within Azerbaijan, dialing a number in Hajigabul requires the national trunk prefix 0, followed by the NDC 212, and the subscriber number. The subscriber number for the 2120 prefix is typically 6 digits, resulting in a total national significant number length of 9 digits (including the leading 0). For example, to call a number with the local extension 123456, a caller from Baku would dial: 0 212 0 123456.

International callers must use the country code +994, followed by the NDC without the leading trunk prefix, and the subscriber number. The same example would be dialed as: +994 212 0 123456. It is important to note that the NDC 212 is not an overlay code; it is the sole geographic code for the district. There are no overlay plans in effect for this region, so no additional digits are required for local calls.

Numbering and Routing Considerations

The 2120 prefix is a geographic allocation, meaning that the number is tied to a physical location. Calls to these numbers are routed over the PSTN and are subject to standard fixed-line tariffs. In recent years, Azerbaijan has seen a migration towards VoIP and mobile services, but fixed-line numbers remain important for businesses and government offices. When calling from abroad, it is advisable to check with your service provider for international dialing rates, as they may vary. For local callers, calls to geographic numbers are typically charged at a lower rate than mobile calls.

In summary, the 2120 prefix is an integral part of Azerbaijan's telecommunications infrastructure, serving the Hajigabul district with reliable fixed-line services. Understanding the correct dialing format ensures seamless connectivity for both domestic and international callers.
