Area Code 474 – Lagos de Moreno/Paso de Cuarenta, JAL

Overview of Area Code 474

Area code 474 is a geographic dialing code within the Mexican numbering plan, assigned to the region encompassing Lagos de Moreno and the surrounding locality of Paso de Cuarenta in the state of Jalisco. This area code is part of the North American Numbering Plan (NANP) under the country code +52 for Mexico. The region is known for its historical significance and growing economic activity, making it a key telecommunications hub in the Altos Sur region of Jalisco.

Geographic Coverage and Jurisdiction

The 474 code serves the municipality of Lagos de Moreno and its adjacent communities, including Paso de Cuarenta. Lagos de Moreno is a city with deep colonial heritage, often referred to as the "Athens of Jalisco" due to its cultural contributions. The area is administratively part of the state of Jalisco, and the code covers both urban and rural zones within the municipality. Nearby cities such as León, Guanajuato, are reachable via different area codes, but 474 is exclusively for the Lagos de Moreno area.

Dialing Formats and Instructions

For callers within Mexico, the national dialing format requires the long-distance prefix 01 followed by the area code and the local 7-digit number. For example, to call a landline in Lagos de Moreno from Mexico City, you would dial: 01 474 XXX XXXX. For international callers, the format is +52 474 XXX XXXX. Note that the area code is an integral part of the 10-digit national number, and omitting the leading zero or country code will result in a failed call.

Numbering and Overlay Considerations

As of the latest ITU-T E.164 guidelines, the 474 area code does not have an overlay, meaning it is the sole code for the region. The local numbers are 7 digits long, and the total subscriber number length is 10 digits when including the area code. The numbering capacity is sufficient for the current population, but as the region grows, future overlays may be introduced. For now, callers should always use the 10-digit dialing format for all calls within Mexico, even for local calls, as per the national dialing plan.

Practical Tips for Callers

When calling from abroad, ensure you have the correct international exit code (e.g., 011 from the US/Canada) before dialing +52. For mobile calls, the same area code applies, but mobile numbers may be ported to other regions; however, the area code remains the same for the original assignment. Always verify the number with the recipient to avoid misdialing, especially when using VoIP services that may require different dialing protocols.
