📍 Geographic Location of Michoacan
Geographic Overview
Area code 455 is a geographic National Destination Code (NDC) assigned to the state of Michoacán, Mexico, under the national numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT). This code serves the central-western region of the country, with its primary coverage centered on the municipality of Puruándiro and its surrounding communities. The area is characterized by a mix of agricultural towns and small urban centers, and the code is used for fixed-line PSTN services, as well as for some fixed wireless and VoIP-based local services.
Coverage and Local Dialing
The 455 area code covers a specific portion of the state, including localities such as Puruándiro, and nearby areas that fall within the same local calling area. For local calls within the 455 region, callers can dial the seven-digit local number directly without the area code. However, when calling from outside the region but still within Mexico, the full national format must be used: 01 455 XXX XXXX. This includes the long-distance prefix '01' followed by the area code and the seven-digit subscriber number.
International Dialing Format
For callers from outside Mexico, the international format is essential. To reach a number in the 455 area code, you must dial your country's international access code (e.g., 011 from the US/Canada), followed by Mexico's country code +52, then the area code 455, and finally the seven-digit local number. The complete international dialing sequence is: +52 455 XXX XXXX. For example, a number in Puruándiro might be dialed as +52 455 123 4567.
Overlays and Numbering
As of the latest IFT updates, there are no overlay codes in the 455 region, meaning the area code is not shared with another NDC in the same geographic area. This simplifies dialing procedures, as there is no need for ten-digit local dialing within the region. However, it is always advisable to confirm the exact dialing procedure with your local service provider, as numbering plan changes can occur.
Caller Instructions
- Local callers (within 455): Dial the seven-digit number directly.
- National callers (outside 455): Dial 01 455 followed by the seven-digit number.
- International callers: Dial your exit code, then +52 455, then the seven-digit number.
Understanding these formats ensures seamless connectivity to businesses and residents in this part of Michoacán, whether you are placing a call from a landline, mobile phone, or VoIP service.
