Area Code 452 – Nuevo San Juan Parangaricutiro/Uruapan, MICH

Geographic Coverage and Administrative Jurisdiction

The +52 452 area code is a geographic numbering resource assigned to the western region of the Mexican state of Michoacán de Ocampo. It serves a territory that includes the city of Uruapan, the municipal seat of Uruapan Municipality, and the surrounding communities such as Nuevo San Juan Parangaricutiro, Tingambato, and Ziracuaretiro. This area code is part of the national numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT) and is designated for fixed-line PSTN services, although some local carriers may offer VoIP-based fixed lines under this code.

Primary Cities and Local Dialing

The principal urban center within the 452 area code is Uruapan, known as the world capital of avocado production. Other notable localities include the indigenous community of Nuevo San Juan Parangaricutiro, which is famous for the San Juan Parangaricutiro Church partially buried by the Paricutín volcano. For local calls within the same area code, subscribers dial the seven-digit local number directly, without the area code. For example, to call a fixed line in Uruapan from another line in Uruapan, you would dial 123-4567 (using a placeholder local number).

International and National Dialing Formats

For callers from other parts of Mexico, the national long-distance format requires dialing the long-distance prefix 01, followed by the area code and the local number: 01 452 123-4567. For international callers, the format is the Mexican country code +52, the area code, and the local number: +52 452 123-4567. When dialing from a mobile phone in Mexico, it is common to use the international format (+52 452...) even for national calls, as this ensures proper routing across different carriers.

Overlay and Numbering Considerations

Currently, the 452 area code does not have an overlay, meaning that the region is served exclusively by this single area code. However, due to increasing demand for telecommunication services, the IFT periodically reviews numbering resources. Subscribers should be aware that number portability allows users to retain their numbers when switching between fixed-line operators within the same geographic area. Additionally, the area code is not assigned to mobile services; mobile numbers in Mexico are identified by the +52 1 prefix followed by a ten-digit number, and they are non-geographic. Therefore, when calling a mobile phone in Uruapan, you would not use the 452 area code but rather the mobile number's own prefix.

Caller Instructions

For local callers: simply dial the seven-digit number. For national callers outside the area: dial 01 452 followed by the local number. For international callers: dial +52 452 followed by the local number. Always verify the local number length (seven digits) and avoid omitting the area code when calling from outside the region.
