📍 Geographic Location of San Francisco Del Rincon, GTO
Geographic Overview
The +52 476 area code is a geographic National Destination Code (NDC) assigned to the municipality of San Francisco del Rincón, located in the state of Guanajuato (GTO), Mexico. This region is part of the Bajío area, an important industrial and agricultural hub. The coverage area includes the city of San Francisco del Rincón and surrounding localities, such as San Roque, El Maguey, and other nearby communities. The code is administered under Mexico's national numbering plan, which follows ITU-T E.164 recommendations.
Dialing Formats
For callers within Mexico, the local dialing format requires the national trunk prefix '01' followed by the area code and the local subscriber number. For example, to call a landline in San Francisco del Rincón from elsewhere in Mexico, you would dial: 01 476 XXX XX XX (where X represents the 7-digit local number). For international callers, the format is +52 476 XXX XX XX. Note that the area code is an essential part of the number; it cannot be omitted when dialing from outside the local area.
Geographic and Administrative Context
San Francisco del Rincón is known for its hat-making industry and is part of the Metropolitan Area of León, which influences its economic and social dynamics. The area code 476 is shared across the municipality, and no overlay codes have been implemented, meaning that the 7-digit local numbers are unique within this NDC. The numbering capacity is sufficient for the current population and business density, but future growth may require additional measures.
Caller Instructions
For local callers within the 476 area code, it is possible to dial only the 7-digit subscriber number without the area code, depending on the local exchange configuration. However, for clarity and to avoid misdialing, it is recommended to always use the full national format when calling from mobile phones or VoIP services. For foreign callers, it is crucial to replace the '+' with the appropriate international access code (e.g., 011 from the US and Canada) when dialing from a landline. Always verify the subscriber number length, as Mexican geographic numbers typically have 7 digits after the area code.
Service and Usage Notes
Numbers under 476 are primarily used for fixed-line services (PSTN) and may also be used for VoIP services that provide geographic numbers. These numbers are not portable to mobile networks in the traditional sense, but number portability within fixed services is possible. When calling from abroad, be aware of time zone differences (Central Time Zone, UTC-6, with daylight saving adjustments). For emergency services, always dial the national emergency number 911, regardless of the area code.
