Area Code 2540 – San Pedro Sula, Cortés

Overview of Area Code 2540

Area code 2540 is a geographic numbering resource assigned within the Honduran national numbering plan, specifically serving the western sector of San Pedro Sula, the country's industrial and commercial capital, located in the department of Cortés. As part of the E.164 country code +504, this prefix is used for fixed-line (PSTN) services, including traditional copper lines and modern fiber-optic or cable-based telephony. San Pedro Sula is the second-largest city in Honduras and a major economic hub, hosting numerous maquiladoras, financial institutions, and logistics centers.

Geographic Coverage and Administration

The 2540 area code covers neighborhoods and districts in the western part of San Pedro Sula, including areas near the Merendón mountain range and the Chamelecón river. The administrative jurisdiction falls under the municipality of San Pedro Sula, Cortés. While the prefix is geographically tied to this zone, number portability may allow subscribers to retain their 2540 numbers even if they relocate within the national territory, subject to regulatory provisions by the Comisión Nacional de Telecomunicaciones (CONATEL).

Dialing Formats and Caller Instructions

Honduras uses a closed numbering plan, meaning that the national significant number (NSN) is always eight digits long, with no trunk prefix. The area code is not separated by a leading zero when dialing domestically. To call a 2540 number from within Honduras, simply dial the eight-digit number: 2540-XXXX. For international callers, the format is +504 2540-XXXX (or 00504 2540-XXXX from countries using the international prefix 00). For example, a local call to a business would be dialed as 2540-1234, while a caller from the United States would dial 011 504 2540-1234.

Overlays and Numbering Considerations

As of the latest updates, there are no overlay codes for the San Pedro Sula area; the 2540 prefix is unique to this region. However, due to increasing demand, CONATEL may introduce additional area codes or renumbering in the future. For now, all fixed-line numbers in San Pedro Sula start with 25, 26, or 27, with 2540 being one of the central office codes. When dialing from a mobile phone in Honduras, the same eight-digit number is used without any additional prefix.

Practical Tips for Callers

For local callers, ensure you have the complete eight-digit number; omitting digits will result in a failed call. For international callers, always include the country code +504 and drop any leading zero that might appear in local listings (though Honduran numbers typically do not have a leading zero). Be aware that rates for international calls to Honduras vary by carrier, and VoIP services may offer lower rates. If you encounter issues, verify the number with the recipient, as mobile numbers in Honduras also start with 3, 8, or 9, and are not part of the 2540 geographic range.
