Area Code 245 – Puebla

Overview of Area Code 245 (Puebla, Mexico)

Area code 245 is a geographic National Destination Code (NDC) within the Mexican numbering plan, assigned to the state of Puebla. It serves a region that includes the city of Tehuacán and its surrounding municipalities, as well as parts of the Sierra Negra and the Mixteca Poblana. This area code is part of the North American Numbering Plan (NANP) under country code +52, but it follows Mexico's specific dialing procedures.

Geographic Coverage and Administrative Jurisdiction

The 245 area code covers the southeastern portion of the state of Puebla. Key localities include Tehuacán (the largest city in this zone), as well as communities such as Ajalpan, Altepexi, Coxcatlán, and Zinacatepec. The region is known for its agricultural production, mineral water bottling industry, and as a commercial hub connecting Puebla with Oaxaca and Veracruz. Administratively, these areas fall under the jurisdiction of the state of Puebla, and the code is regulated by the Instituto Federal de Telecomunicaciones (IFT) in Mexico.

Dialing Formats and Procedures

For callers within Mexico, dialing a number in the 245 area code requires the format: 01 245 XXX XX XX (for landline calls) or 245 XXX XX XX (for mobile calls, depending on the operator). However, since 2019, Mexico has unified dialing for all national calls: you must dial the 10-digit number preceded by the long-distance prefix. For international callers, the format is: +52 245 XXX XX XX. For example, to call a landline in Tehuacán from the United States, you would dial +52 245 123 45 67.

Overlay and Numbering Changes

As of now, the 245 area code does not have an overlay. However, due to increasing demand for telephone numbers, the IFT may introduce overlays in the future. If an overlay is implemented, local calls would require 10-digit dialing (area code + number) even for calls within the same area code. Currently, within the 245 region, local calls can be made using 7-digit dialing (the local subscriber number) if you are calling from a landline in the same exchange area, but for clarity and future-proofing, it is recommended to always use the full 10-digit format.

Caller Instructions

Local callers (within 245): For landline-to-landline calls within the same city, you may dial the 7-digit local number. However, for calls between different cities within the 245 area code, you must dial the long-distance prefix 01, then 245, then the 7-digit number. National callers (outside 245): Dial 01 245 XXX XX XX. International callers: Dial your country's exit code, then 52, then 245, then the 7-digit number. Remember that mobile numbers in Mexico are always 10 digits and are not tied to geographic area codes; they have their own prefixes (e.g., 222, 238, etc.). If you receive a call from a number starting with +52 245, it is a fixed-line call from the Puebla region.
