Area Code 316 – Jalisco

Overview of Area Code 316 (Jalisco, Mexico)

Area code 316 is a geographic National Destination Code (NDC) assigned to the state of Jalisco, Mexico, under the country calling code +52. This code serves a specific region within Jalisco, primarily covering the municipality of Zapotlán el Grande (also known as Ciudad Guzmán) and its surrounding areas, including communities such as Gómez Farías, San Gabriel, and Tolimán. The region is located in the southern part of Jalisco, approximately 120 kilometers south of Guadalajara, the state capital.

As a geographic code, 316 is used for fixed-line (PSTN) services, including traditional copper lines, cable telephony, and VoIP services that are registered to a physical address within the covered area. The code is not portable outside its geographic region; however, number portability within the same area is possible among service providers.

Dialing Formats

When dialing a number with area code 316, the format depends on the caller's location:

• Local calls (within area code 316): In Mexico, local calls are typically dialed using only the 7-digit local number (e.g., 123-4567). However, due to the national dialing plan changes implemented in 2019, all calls within Mexico now require the full 10-digit number (area code + local number), even for local calls. Therefore, to call a neighbor in Ciudad Guzmán, you would dial 316 123 4567.
• National long-distance calls (from other area codes in Mexico): Dial the prefix 01 followed by the area code and local number. For example, from Mexico City, you would dial 01 316 123 4567.
• International calls (from outside Mexico): Dial your country's international access code (e.g., 011 from the US/Canada), then Mexico's country code 52, then the area code (without the leading zero) and the local number. For example, from the United States, you would dial 011 52 316 123 4567. From most European countries, you would dial 00 52 316 123 4567.

Important Considerations

Mexico's numbering plan is regulated by the Instituto Federal de Telecomunicaciones (IFT). Since August 3, 2019, all calls, including local, must be dialed using the 10-digit national number (area code + subscriber number). The old practice of dialing only 7 digits for local calls is no longer valid. This change was implemented to facilitate number portability and the expansion of telecommunication services.

For callers from abroad, it is essential to omit the leading '0' that is used in national long-distance dialing. The country code +52 is always required. When saving Mexican numbers in your mobile phone, it is recommended to store them in international format: +52 316 123 4567, to ensure proper routing when roaming or receiving calls from abroad.

Area code 316 is not associated with toll-free or premium-rate services; it is exclusively a geographic code for regular fixed-line telephony. If you are planning to call a business or residence in the southern region of Jalisco, using the correct dialing format will ensure your call connects without issues.
