Geographic Coverage and Administrative Jurisdiction
The Mexican area code +52 463 is a geographic National Destination Code (NDC) assigned to the municipality of Jalpa and its surrounding areas within the state of Zacatecas. This code serves the town of Jalpa, which functions as the administrative and commercial hub for the region, along with nearby localities such as Tabasco (not to be confused with the state of Tabasco), Huanusco, and other rural communities. The jurisdiction falls under the Secretariat of Infrastructure, Communications and Transportation (SICT) and is managed by the Federal Telecommunications Institute (IFT).
Dialing Formats and Caller Instructions
For local callers within Mexico, the prefix is dialed as 463 followed by the seven-digit local number. The complete national format is 01 463 XXX XXXX when dialing from other Mexican states. However, for international callers, the full E.164 format is +52 463 XXX XXXX. For example, to call a landline in Jalpa from the United States, you would dial 011 52 463 XXX XXXX (or +52 463 XXX XXXX from a mobile).
Geographic vs. Non-Geographic Allocation
As a geographic code, 463 is tied to the physical location of the fixed-line service. This means that the number is associated with the PSTN (Public Switched Telephone Network) infrastructure in that region. It is important to note that while number portability exists in Mexico, fixed-line numbers are typically ported within the same geographic area, so a number with this prefix will generally remain associated with the Jalpa region even if the provider changes.
Overlay Considerations
Currently, there is no overlay code for the Jalpa area, meaning 463 is the sole NDC for this region. This simplifies dialing, as there is no need for ten-digit dialing within the local area. However, as demand for numbers grows, the IFT may introduce an overlay, which would require changes to local dialing procedures.
Services and Usage
The 463 prefix is used for fixed-line services, including residential and business telephony, as well as internet and data services provided over the PSTN. It is not assigned to mobile networks, which use dedicated mobile prefixes (e.g., 1, 2, 3, etc.) under the +52 country code. Callers should be aware that calls to this number are charged according to standard national or international rates, depending on the origin.
