📍 Geographic Location of Guerrero
Overview of Area Code 727
Area code 727 is a geographic National Destination Code (NDC) assigned to the state of Guerrero, Mexico, under the country's numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT). It serves a specific region within Guerrero, primarily covering the municipality of Taxco de Alarcón and its surrounding areas. This includes the city of Taxco, renowned for its silver craftsmanship and colonial architecture, as well as nearby towns such as Iguala de la Independencia and Teloloapan. The code is used for fixed-line (PSTN) services, and, as with all Mexican geographic codes, it is not assigned to mobile services.
Geographic Coverage and Administrative Jurisdiction
The 727 area code covers the northern and central parts of Guerrero, a state located in southern Mexico. The region is characterized by mountainous terrain and is part of the Sierra Madre del Sur. The principal city served is Taxco de Alarcón, a major tourist destination. Other localities within the coverage area include Buenavista de Cuéllar, Cocula, and Huitzuco. The administrative jurisdiction falls under the state of Guerrero, and the code is managed by the IFT, which allocates numbering resources to licensed carriers.
Dialing Formats and Caller Instructions
For local callers within Mexico, dialing a number in area code 727 requires the national long-distance prefix '01' followed by the area code and the seven-digit local number. For example, to call a fixed line in Taxco from Mexico City, you would dial: 01 727 123 4567. For international callers, the format is: +52 727 123 4567 (or 011 52 727 123 4567 from the US/Canada). It is important to note that when dialing from a mobile phone within Mexico, the '01' prefix is often replaced by the '+' sign and country code, but the area code and number remain the same.
Overlay and Numbering Considerations
Currently, area code 727 does not have an overlay; it is the sole code for its geographic region. However, as demand for numbers grows, the IFT may introduce an overlay in the future. In such a case, ten-digit dialing would become mandatory for all calls within the region. Until then, local calls within the same area code may be dialed using only the seven-digit local number, but it is always safe to use the full national format to avoid confusion.
Practical Information for Callers
When calling a business or residence in the 727 area code, expect to reach a fixed line. If the number is not answering, consider that the business may have alternative contact methods. For tourists, many hotels and businesses in Taxco may provide local numbers; international visitors should store numbers in international format (+52 727...) to ensure proper dialing from abroad. As with all geographic codes in Mexico, numbers are not portable to other regions, but they may be ported between fixed-line carriers within the same area.
