📍 Geographic Location of Michoacan
Geographic Overview
The area code 424 is a geographic National Destination Code (NDC) assigned to the state of Michoacán, Mexico, under the country calling code +52. This code serves the central-western region of the state, primarily covering the municipality of Cotija and its surrounding areas. Cotija is a historic town known for its dairy production, particularly the famous Cotija cheese, and is situated near the border with the state of Jalisco. The code is administered by the Federal Telecommunications Institute (IFT) and is used for fixed-line PSTN services.
Dialing Formats
When calling a number in the 424 area code from within Mexico, the national trunk prefix 01 is used, followed by the area code and the local 7-digit subscriber number. For example, to call a local number in Cotija from Mexico City, you would dial: 01 424 XXX XXXX. For international callers, the format is +52 424 XXX XXXX. Note that the leading trunk prefix is not used when dialing from abroad.
Local Calling and Overlays
Within the 424 area code, local calls are dialed using the 7-digit number alone, without the area code. There are no overlay codes currently assigned to this region, meaning the 424 code is the sole NDC for the area. However, as with all Mexican geographic codes, number portability allows subscribers to retain their numbers when switching between fixed-line providers, though the geographic assignment remains tied to the original location.
Coverage and Communities
The 424 code covers Cotija and nearby communities such as La Yerbabuena, El Cerrito, and other rural localities within the municipality. The region is predominantly rural, with a mix of agricultural and small commercial activities. The code is not used for mobile services; mobile numbers in Mexico are identified by their own non-geographic prefixes (e.g., 44x, 55x) and are dialed differently.
Caller Instructions
For local callers within the 424 area, simply dial the 7-digit number. For long-distance calls within Mexico, dial 01 before the area code. For international callers, always use +52 followed by the 424 code and the subscriber number. Ensure you drop any leading zeros from the local number when dialing internationally. For example, if the local number is 123 4567, the international format is +52 424 123 4567.
