📍 Geographic Location of Hidalgo
Geographic Overview and Jurisdiction
Area code 774 is a geographic National Destination Code (NDC) assigned to the state of Hidalgo, Mexico, under the international country calling code +52. This prefix serves the central-eastern portion of the country, with its primary urban center being the city of Pachuca de Soto, the state capital. The coverage area extends to surrounding municipalities within the Pachuca metropolitan area and other localities in Hidalgo, including Mineral de la Reforma, San Agustín Tlaxiaca, and Zempoala. The numbering zone is administered under the Federal Telecommunications Institute (IFT) guidelines, which allocate geographic NDCs based on state and municipal boundaries.
Dialing Formats and Usage
For local calls within the 774 area code, subscribers in Mexico must dial the seven-digit local number preceded by the area code, even for calls within the same city. The standard national dialing format is 01 774 XXX XXXX for calls originating from other area codes within Mexico. For international callers, the complete E.164 format is +52 774 XXX XXXX, where +52 is the Mexico country code, 774 is the NDC, and the subscriber number consists of seven digits. It is important to note that Mexico eliminated the need to dial '01' for national long-distance calls in 2019, but the prefix remains part of the national numbering plan for routing purposes.
Overlays and Numbering Considerations
Currently, area code 774 does not have an overlay code; it is the sole geographic NDC for this region. However, due to growing demand for telecommunication services, the IFT periodically reviews numbering resources. Should an overlay be introduced in the future, ten-digit dialing would become mandatory for all local calls. For now, callers should always include the area code when dialing from any phone, whether mobile or fixed, to ensure correct routing.
Caller Instructions
For local callers within Hidalgo, simply dial 774 XXX XXXX (ten digits) to reach any fixed or mobile line in the area. For callers from other parts of Mexico, dial 774 XXX XXXX after the national long-distance prefix (if applicable) or directly from mobile phones. International callers should dial +52 774 XXX XXXX from any country. When calling from a mobile phone, the '+' sign is typically used to denote the international access code, but you may also dial the specific international prefix of your country (e.g., 011 from the US/Canada) followed by 52 and the number.
Economic and Demographic Context
Pachuca, the main city served by this code, is a hub for mining, commerce, and government services. The region has seen steady growth in business and tourism, making reliable telecommunication services essential. Understanding the correct dialing procedures ensures seamless connectivity for both residents and visitors.
