Overview of Area Code 498
Area code 498 is a geographic numbering plan area within the North American Numbering Plan under the country code +52, assigned to Mexico. It serves the central-northern region of the state of Zacatecas, covering the municipalities of Fresnillo, Calera, and surrounding communities. The code is administered by the Instituto Federal de Telecomunicaciones (IFT) and is allocated to fixed-line PSTN services, although some local carriers may offer VoIP-based fixed lines using this code.
Geographic Coverage and Key Localities
The 498 area code primarily covers the city of Fresnillo, known for its mining industry, and the municipality of Calera, along with smaller towns such as Saín Alto and Morelos. These areas are part of the state of Zacatecas, which borders the states of Durango, Coahuila, San Luis Potosí, and Aguascalientes. The region is characterized by a mix of urban and rural communities, with economic activities centered on mining, agriculture, and commerce.
Dialing Formats and Instructions
For callers within Mexico, dialing a number in area code 498 requires the national long-distance prefix '01' followed by the area code and the seven-digit local number. For example, to call a fixed line in Fresnillo with the local number 1234567, you would dial: 01 498 123 4567.
For international callers, the format is: +52 498 123 4567 (or 011 52 498 123 4567 from the US/Canada). The plus sign represents the international access code, and the country code for Mexico is 52. Note that the leading '01' is not used when dialing from abroad.
Overlay and Numbering Considerations
As of the latest IFT updates, area code 498 does not have an overlay code, meaning it is the sole area code for its geographic region. However, due to the growth of mobile services, many residents may have mobile numbers with different area codes (e.g., 492 for Zacatecas city). When dialing a mobile number, the same national and international formats apply, but the area code may differ. It is always advisable to confirm the correct area code for the specific number you are dialing.
Caller Instructions
Local callers within the same area code can often dial just the seven-digit local number without the area code, but this depends on the local carrier's configuration. For long-distance calls within Mexico, always include the '01' prefix. For international callers, ensure you have the correct country and area codes. If you encounter issues, contact your service provider for assistance.
