Area Code 495 – Aguascalientes/Jalisco

Area Code 495: Geographic Coverage and Administration

Area code 495 is a geographic National Destination Code (NDC) assigned under the Mexico numbering plan, which follows ITU-T E.164 recommendations. It serves a defined region spanning parts of the states of Aguascalientes and Jalisco, in central-western Mexico. The code is administered by the Instituto Federal de Telecomunicaciones (IFT), Mexico's telecommunications regulatory authority. The covered territory includes municipalities and localities such as Calvillo in Aguascalientes, and Lagos de Moreno and Encarnación de Díaz in Jalisco. These areas are known for their agricultural production, growing industrial corridors, and cultural heritage.

Dialing Formats and Caller Instructions

For callers within Mexico, the national long-distance format requires dialing the prefix 01 followed by the area code and the local 7-digit subscriber number. For example, to call a landline in Calvillo from Mexico City, you would dial: 01 495 123 4567. For international callers, the format is: +52 495 123 4567 (or 011 52 495 123 4567 from the US/Canada). When dialing locally within the same area code, the 10-digit number (including area code) is typically used, as Mexico uses a closed numbering plan for local calls in many regions. No overlay codes have been introduced for this area, so the 495 code remains the sole geographic code for the region.

Numbering and Routing Considerations

Subscriber numbers within area code 495 are 7 digits long, conforming to the national standard. The code is used exclusively for fixed-line PSTN and VoIP services that are geographically tied to the region. Mobile numbers in Mexico are assigned distinct non-geographic NDCs (e.g., 1, 2, 3, etc.) and are not part of area code 495. When routing calls, the Mexican network identifies the geographic destination based on the NDC, ensuring proper interconnection between local exchange carriers. As with all Mexican geographic codes, number portability is available, allowing users to retain their numbers when changing service providers within the same geographic area, but porting does not change the geographic association of the code.

Practical Guidance for Callers

• Domestic callers: Always dial 01 before the area code for long-distance calls from other parts of Mexico.
• International callers: Use the country code +52, followed by the area code and the local number, omitting the leading 0 used domestically.
• Local calls: Within the same area code, dial the 10-digit number (495 + 7-digit number) to ensure proper routing.
• Businesses: When publishing contact numbers, always include the area code and, for international audiences, the +52 country code to avoid confusion.
