Area Code 224 – Puebla

Overview of Area Code 224 (Puebla, Mexico)

Area code 224 is a geographic National Destination Code (NDC) assigned to the state of Puebla in Mexico, specifically serving the city of Puebla and its surrounding metropolitan area. It is part of the North American Numbering Plan (NANP) under the country code +52, following the ITU-T E.164 international standard. The code covers both the capital city, Puebla de Zaragoza, and several adjacent municipalities, including San Andrés Cholula, San Pedro Cholula, and Cuautlancingo. This region is a major economic and cultural hub in central Mexico, home to numerous businesses, government institutions, and the Benemérita Universidad Autónoma de Puebla (BUAP).

Dialing Formats and Usage

Within Mexico, calls to numbers in area code 224 require the national long-distance prefix '01' followed by the area code and the 7-digit local number. The complete national format is: 01 224 XXX XXXX. For international callers, the format is +52 224 XXX XXXX (or 011 52 224 XXX XXXX from the US/Canada). It is important to note that Mexican fixed-line numbers are 10 digits in total (including the area code), and there are no overlay codes currently assigned to this region, so the area code is mandatory for all calls, even local ones, when dialing from a different area code.

Geographic Coverage and Administration

The 224 area code is administered by the Federal Telecommunications Institute (IFT) and is assigned to fixed-line services (PSTN and VoIP). It serves the city of Puebla, which is the fourth-largest city in Mexico, and its metropolitan zone. The region is known for its industrial parks, commercial centers, and historical significance. Local numbers are 7 digits long, and the area code is used for both residential and business lines. When dialing locally within the same area code, callers may omit the long-distance prefix, but the area code is still required for calls from mobile phones or other regions.

Caller Instructions

• Local callers (within Puebla): Dial the 7-digit local number directly (e.g., 234 5678).
• National callers (outside Puebla): Dial 01 224 234 5678.
• International callers: Dial +52 224 234 5678.
• Mobile callers in Mexico: Dial 044 224 234 5678 if calling from a Mexican mobile to a fixed line (though this is less common now, as mobile-to-fixed calls typically require 01).

For businesses, having a local 224 number establishes a presence in Puebla and is essential for reaching customers in the region. VoIP users should ensure their service provider supports geographic numbers in Mexico to obtain a 224 code.
