Area Code 2237 – Principal

Geographic Coverage and Administrative Jurisdiction

The area code 2237 is a geographic National Destination Code (NDC) assigned to the central-western region of Honduras, specifically serving the city of Comayagua and its surrounding municipalities. Comayagua, the former capital of Honduras, is the administrative seat of the Comayagua Department and lies in the mountainous interior, approximately 80 kilometers northwest of Tegucigalpa. This prefix is used for fixed-line (PSTN) services within this jurisdiction, including residential, business, and government lines.

Dialing Formats and Caller Instructions

When calling a fixed-line number in Comayagua from within Honduras, subscribers must dial the national trunk prefix 0, followed by the NDC 2237 and the subscriber number. The complete national format is:

• 0 2237 XXXX (where XXXX is the 4-digit local subscriber number)

For international callers, the Honduran country code +504 replaces the trunk prefix, and the NDC is dialed without the leading zero. The international format is:

• +504 2237 XXXX

For example, a local call to a business in Comayagua would be dialed as 0 2237 1234, while a caller from the United States would dial +504 2237 1234.

Overlay and Numbering Considerations

As of the latest ITU-T E.164 national numbering plan updates, Honduras has not implemented overlay codes for this geographic area. The NDC 2237 is exclusively assigned to the Comayagua region, and no other NDCs share the same geographic coverage. However, due to the increasing demand for fixed-line services, the Comisión Nacional de Telecomunicaciones (CONATEL) may introduce additional NDCs in the future, but as of now, 2237 remains the sole code for this area.

Call Routing and Network Infrastructure

Fixed-line numbers under 2237 are traditionally delivered over the PSTN, but many operators now offer VoIP-based fixed-line services that still use the same geographic NDC. Calls to these numbers are routed based on the NDC, ensuring that they terminate at the correct central office in Comayagua. For international callers, the call is routed through the Honduran international gateway, which recognizes the country code +504 and the NDC to complete the connection.

It is important to note that while mobile numbers in Honduras also use the country code +504, they are identified by their own NDCs (e.g., 9xxx, 8xxx) and are non-geographic. Therefore, dialing +504 2237 XXXX will always reach a fixed-line in Comayagua, not a mobile device.
