Overview of Area Code 431 (Jalostotitlan/Villa Obregon, JAL)
Area code 431 is a geographic National Destination Code (NDC) assigned to the municipalities of Jalostotitlan and Villa Obregon in the state of Jalisco (JAL), Mexico. This code is part of the North American Numbering Plan (NANP) administered under the Mexican numbering plan by the Instituto Federal de Telecomunicaciones (IFT). The region is located in the Los Altos de Jalisco area, a highland zone known for its agricultural production and cultural heritage.
Geographic Coverage and Jurisdiction
The 431 area code serves a defined geographic area within Jalisco, primarily covering the municipalities of Jalostotitlan (the largest city) and Villa Obregon, along with surrounding rural communities and ranches. Jalostotitlan is the municipal seat and the main commercial hub, while Villa Obregon is a smaller town located approximately 15 kilometers to the south. The region is administratively part of the state of Jalisco and is served by local PSTN and VoIP providers.
Dialing Formats
For local calls within the 431 area code, callers can dial the 7-digit local number directly. However, for calls from other area codes within Mexico, the full national format must be used: 01 431 XXX XXXX. For international callers, the format is +52 431 XXX XXXX. For example, to call a landline in Jalostotitlan from the United States, one would dial +52 431 123 4567.
Overlay Considerations
As of the latest IFT updates, area code 431 does not have an overlay code; it is the sole NDC for this region. This simplifies dialing, as there is no need for 10-digit dialing within the area. However, users should always verify the current numbering plan, as overlays may be introduced in the future to meet demand.
Caller Instructions
- Local callers (within 431): Dial the 7-digit subscriber number directly.
- National callers (outside 431): Dial 01 followed by 431 and the 7-digit number.
- International callers: Dial the international access code (e.g., 011 from the US), then Mexico's country code 52, then 431 and the 7-digit number.
This area code is used for fixed-line services, and numbers are typically assigned to residential and business lines. Mobile numbers in Mexico use different prefixes (e.g., 044 or 045) and are not tied to geographic regions, so a mobile number will not have the 431 code.
