Area Code 748 – Hidalgo

Geographic Coverage and Administrative Jurisdiction

The +52 748 area code is a geographic National Destination Code (NDC) assigned to the state of Hidalgo, Mexico. It serves the central-western portion of the state, with the city of Ixmiquilpan as its principal urban center. The coverage area includes the municipalities of Ixmiquilpan, Zimapán, Tasquillo, Alfajayucan, and Cardonal, among others. This region is part of the Mezquital Valley, known for its thermal springs and mining heritage.

Dialing Formats and Caller Instructions

For callers within Mexico, the national long-distance format requires dialing the long-distance prefix 01, followed by the area code and the local 7-digit number. For example, to call a landline in Ixmiquilpan from Mexico City, you would dial: 01 748 123 4567.

For international callers, the ITU-T E.164 format applies: dial the international access prefix (e.g., 00 from most countries, or + from mobile phones), followed by Mexico's country code 52, the area code 748, and the local 7-digit number. Thus, a caller from the United States would dial: +52 748 123 4567 (or 011 52 748 123 4567).

Local Dialing and Overlay Considerations

Within the 748 area code region, local calls are made by dialing only the 7-digit subscriber number. No overlay code is currently assigned to this area, so 10-digit dialing is not required for local calls. However, as Mexico transitions to a unified national dialing plan, it is advisable to always store and share numbers in the full international format (+52 748 XXX XXXX) to ensure compatibility with mobile and VoIP systems.

Numbering and Regulatory Notes

Area code 748 is part of Mexico's open numbering plan, administered by the Federal Telecommunications Institute (IFT). Subscriber numbers within this code are 7 digits long, and the code is exclusively used for fixed-line services (PSTN). Mobile numbers in Mexico are identified by their own non-geographic prefixes (e.g., 55, 56, 44, etc.) and are not tied to this area code. When calling a Mexican mobile number from abroad, you must dial +52 followed by the 10-digit mobile number, omitting any leading '044' or '045' that may be used domestically for mobile calls.

Practical Tips for Callers

• Always verify the local number length before dialing; numbers in this area are 7 digits.
• For calls from outside Mexico, replace the '+' with your country's international exit code (e.g., 011 in the US/Canada).
• If you are using VoIP services, ensure that you include the country code and area code even for domestic calls to avoid routing errors.
