Area Code 593 – Estado de Mexico

Overview of Area Code 593 (Mexico)

Area code 593 is a geographic National Destination Code (NDC) assigned to the Estado de Mexico (State of Mexico), one of the 32 federal entities of Mexico. This state surrounds Mexico City (CDMX) on three sides and is part of the broader Mexico City metropolitan area. The code serves a mix of urban, suburban, and semi-rural communities, including municipalities such as Toluca (the state capital), Metepec, Lerma, and Zinacantepec, as well as other localities within the Toluca Valley. It is important to note that this code is distinct from the country code of Norway (+47) or any other international dialing code; it is exclusively a domestic Mexican area code.

Geographic Coverage and Administrative Jurisdiction

The 593 area code is allocated within the state of Mexico, primarily covering the western portion of the state, with Toluca as the principal city. The region is governed by the state's administrative bodies, and the code is regulated by the Instituto Federal de Telecomunicaciones (IFT), Mexico's telecommunications regulatory authority. The coverage area includes both residential and business districts, and it supports fixed-line services (PSTN) as well as VoIP and other wireline-based services. The geographic boundaries are defined by the state's municipal divisions, and the code does not extend into neighboring states or into Mexico City proper.

Dialing Formats and Caller Instructions

For local callers within the 593 area code, it is necessary to dial the full 10-digit national number, which includes the area code followed by the 7-digit local subscriber number. For example, to call a fixed line in Toluca, a local caller would dial: 593 XXX XXXX. This applies even for calls made from within the same area code, as Mexico adopted a nationwide 10-digit dialing format in 2019, eliminating the need to dial a trunk prefix (01) for domestic long-distance calls.

For international callers, the dialing format is: +52 593 XXX XXXX. The plus sign represents the international access code used in the caller's country (e.g., 011 from the US/Canada), followed by Mexico's country code (52), the area code (593), and the local number. For example, a caller from the United States would dial: 011 52 593 XXX XXXX. When calling from a mobile phone, the plus sign can be used directly: +52 593 XXX XXXX.

Overlay and Numbering Considerations

Currently, the 593 area code does not have an overlay; it is the sole NDC for its geographic region. However, as demand for numbers grows, the IFT may introduce overlays or new area codes in the future. Subscribers in the 593 region can keep their numbers when moving within the same area code, but number portability allows users to switch service providers while retaining their number, even across different technologies (e.g., from fixed to mobile, though mobile numbers are identified by their own prefixes).

For businesses and residents, it is essential to use the correct dialing format to ensure successful call completion. Misunderstandings can arise because some online directories may list numbers without the area code, but the 10-digit format is mandatory for all calls within Mexico, including local calls.
