Area Code 2643 – Santa Bárbara

Geographic Overview

The +504 2643 prefix is a geographic National Destination Code (NDC) assigned to the Santa Bárbara department in Honduras. This area, located in the northwestern part of the country, is known for its mountainous terrain and agricultural production. The code serves the departmental capital, Santa Bárbara city, as well as surrounding municipalities and rural communities within the department's jurisdiction.

Dialing Formats

When calling a landline in Santa Bárbara from within Honduras, subscribers must dial the national trunk prefix '0' followed by the eight-digit subscriber number, which includes the NDC. For example, to reach a local number, you would dial: 0 2643-XXXX. However, from abroad, callers should use the international access code (typically '00' or '+'), followed by the country code 504, and then the eight-digit number without the trunk prefix: +504 2643-XXXX.

Number Structure and Local Dialing

All Honduran fixed-line numbers, including those in Santa Bárbara, consist of eight digits. The first four digits (2643) represent the NDC, while the remaining four digits are the local subscriber number. Within the same NDC area, local calls may be dialed using only the four-digit subscriber number in some legacy systems, but modern networks require the full eight-digit number even for local calls to ensure routing accuracy. No overlay codes are currently in effect for Santa Bárbara; the 2643 code is exclusive to this geographic region.

Caller Instructions

For local callers (within Honduras): Dial '0' followed by '2643' and the four-digit subscriber number. For example, if the subscriber number is 5678, dial 0 2643 5678.

For international callers: Dial your country's exit code (e.g., 011 from the US/Canada), then Honduras country code 504, then the full eight-digit number. For instance, from the US, you would dial 011 504 2643 5678 or use the plus sign: +504 2643 5678.

Regulatory and Technical Notes

The Honduran telecom regulator, CONATEL (Comisión Nacional de Telecomunicaciones), administers numbering resources. Fixed-line services in Santa Bárbara are provided by both incumbent operators and competitive carriers, all of which must adhere to the national numbering plan. Calls to these numbers are routed over the PSTN, and while VoIP services are increasingly used, the geographic significance of the NDC remains for emergency services and number portability. It is important to note that number portability allows subscribers to retain their numbers when switching providers, but the geographic association of the prefix is maintained for routing purposes.
