📍 Geographic Location of Salamanca, GTO
Geographic Coverage and Administrative Jurisdiction
The +52 464 area code is a geographic National Destination Code (NDC) assigned to the city of Salamanca and its surrounding municipalities in the state of Guanajuato (GTO), Mexico. This region is part of the Bajío, an industrial heartland known for its refining and automotive sectors. The numbering area includes Salamanca proper, along with nearby localities such as Valle de Santiago, Jaral del Progreso, and Moroleón (the latter two are partially covered by adjacent codes). The code is administered under the Federal Telecommunications Institute (IFT) of Mexico, which oversees the national numbering plan.
Dialing Formats and Caller Instructions
For local callers within the 464 area code, the standard local dialing format is the seven-digit subscriber number alone. For example, to reach a landline in Salamanca, a local caller would dial 123-4567. However, when calling from outside the area code but still within Mexico, the caller must dial the long-distance prefix 01, followed by the area code and the seven-digit number: 01 464 123 4567. This format applies to both fixed and mobile calls originating from other Mexican NDCs.
International callers should dial the Mexican country code (+52), then the area code (464), and the seven-digit subscriber number, omitting the leading trunk prefix: +52 464 123 4567. It is crucial to note that Mexico's dialing plan does not use a trunk prefix like '0' for international calls; the plus sign and country code are used.
Numbering and Overlay Considerations
As of the latest IFT numbering updates, the 464 area code does not have an overlay code. Subscriber numbers within this NDC are seven digits long, and the total length of a national significant number (NSN) is ten digits (area code + subscriber number). The code is classified as geographic, meaning that the number is tied to a physical location, and tariffs are typically based on the caller's and callee's locations.
For businesses and residents, it is important to note that number portability is available in Mexico, allowing users to retain their numbers when switching service providers, but the geographic association of the code remains unchanged. For VoIP users, the 464 code can be used to obtain a virtual number that routes calls to Salamanca, but the caller must still follow the appropriate dialing format based on their location.
