Area Code 594 – Estado de Mexico

Overview of Area Code 594 (Mexico)

Area code 594 is a geographic National Destination Code (NDC) assigned to the State of Mexico (Estado de México), one of the 32 federal entities of Mexico. This code serves a portion of the state's territory, primarily covering municipalities in the southern and central regions, including but not limited to Amecameca, Atlautla, Ayapango, Chalco (parts), Cocotitlán, Ecatzingo, Juchitepec, Ozumba, Temamatla, Tenango del Aire, Tepetlixpa, and Tlalmanalco. These areas are located to the southeast of Mexico City, near the foothills of the Popocatépetl and Iztaccíhuatl volcanoes.

Geographically, the region is characterized by a mix of urban and rural communities. The city of Amecameca serves as a commercial hub and a gateway to the Izta-Popo National Park. Other notable towns include Chalco, which is part of the greater Mexico City metropolitan area, and Ozumba, known for its traditional markets.

Dialing Formats

When dialing a number within the 594 area code from another location in Mexico (including Mexico City), you must use the national long-distance prefix 01 followed by the area code and the 7-digit local number. The format is:

• National dialing: 01 594 XXX XX XX
• International dialing from abroad: +52 594 XXX XX XX (or 52 594 XXX XX XX)

For example, to call a business in Amecameca from the United States, you would dial +52 594 123 45 67. If you are calling from within Mexico, you would dial 01 594 123 45 67.

Overlay and 10-Digit Dialing

Mexico has implemented a nationwide 10-digit dialing system (area code + 7-digit number) for all calls, eliminating the need for the 01 prefix for long-distance within the country. However, the 01 prefix is still used for toll calls from landlines. For mobile and VoIP users, the 01 prefix is often not required; you can dial the 10-digit number directly. Always check with your service provider for the correct dialing procedure.

Caller Instructions

For local callers: If you are within the 594 area code, you can dial the 7-digit local number directly (without the area code) for calls within the same exchange. For calls to other area codes in Mexico, use the national format.

For international callers: Dial your country's exit code (e.g., 011 from the US/Canada), then Mexico's country code 52, then the area code 594, and the 7-digit local number. For example, from the UK, you would dial 00 52 594 XXX XX XX.

This area code is part of the North American Numbering Plan (NANP) region? No, Mexico is not part of the NANP; it uses its own country code +52. The area code 594 is a geographic code, and numbers are assigned to fixed-line services, though some VoIP services may also use them.
