📍 Geographic Location of Veracruz
Overview of Area Code 278
Area code 278 is a geographic numbering plan area (NPA) within the Mexican dialing plan, assigned to the state of Veracruz. It serves the central and southern portions of the state, including municipalities such as Tierra Blanca, Cosamaloapan, and Tres Valles. This region is part of the Papaloapan River basin, an important agricultural and commercial corridor. The code is administered under the ITU-T E.164 national numbering plan, where the full international dialing format is +52 278 XXX XX XX.
Geographic Coverage and Jurisdiction
The 278 area code covers a predominantly rural and semi-urban territory, with Tierra Blanca as the largest city. Other localities include Carlos A. Carrillo, Ixmatlahuacan, and Acula. The area is known for sugarcane cultivation and livestock. The jurisdiction falls under the Federal Telecommunications Institute (IFT) of Mexico, which regulates numbering resources. Unlike overlay codes in some Mexican cities, 278 is a standalone code for its region, meaning local calls within the same area code do not require the prefix when dialing.
Dialing Formats and Instructions
For local callers within the 278 region, dial only the seven-digit subscriber number (XXX XX XX). For long-distance calls from other Mexican states, dial the national long-distance prefix '01' followed by 278 and the seven-digit number: 01 278 XXX XX XX. International callers must dial their country's exit code (e.g., 011 from the US/Canada), then Mexico's country code 52, then 278, and the subscriber number: +52 278 XXX XX XX. When calling from a mobile phone in Mexico, the same national format applies, but the '01' prefix is often replaced by the carrier's long-distance service; however, standard practice is to dial 01 278... from landlines.
Numbering and Technical Considerations
Subscriber numbers in area 278 are seven digits long, following the format 278 XXX XX XX. The total length of a national significant number (NSN) is ten digits (including area code), which is standard for Mexican geographic numbers. These numbers are primarily used for fixed-line PSTN services, though some may be assigned to VoIP providers that offer geographic numbers. Callers should note that while mobile numbers in Mexico always begin with 1 (after the country code) when dialed internationally, geographic numbers like 278 do not include that extra digit. Therefore, the international format is simply +52 278 XXX XX XX.
Practical Guidance for Callers
For business or personal calls to this region, always verify the correct seven-digit local number. If you are dialing from abroad, ensure you have the correct exit code for your country. For example, from the United States, dial 011 52 278 XXX XX XX. From Europe, dial 00 52 278 XXX XX XX. If you experience routing issues, confirm that the number is still within the 278 area code, as number portability can occasionally reassign numbers to different regions, but this is rare for geographic codes. For emergency services, use the national emergency number 911, which is not tied to area codes.
