📍 Geographic Location of Yucatan
Geographic Coverage and Administrative Jurisdiction
The area code 997 is a geographic National Destination Code (NDC) assigned to the southeastern region of Mexico, specifically within the state of Yucatán. This code serves municipalities located in the eastern and southern parts of the state, with the principal city being Valladolid, a historic colonial town. Other localities covered under this code include Tizimín, Chemax, and Espita. The region is characterized by its rich Mayan heritage and proximity to archaeological sites such as Chichén Itzá and Ek’ Balam.
Dialing Formats and Number Structure
Mexican telephone numbers under geographic area codes follow the national numbering plan defined by the Federal Telecommunications Institute (IFT). For area code 997, local numbers consist of seven digits. When dialing within the same area code, only the seven-digit subscriber number is required. For calls originating from other area codes within Mexico, the full national long-distance format must be used: 01 997 XXX XXXX. International callers must dial +52 997 XXX XXXX (or the alternative +52-1-997-XXX-XXXX when dialing from the United States or Canada, depending on the carrier's routing).
Overlay and Numbering Considerations
As of the latest IFT updates, there is no overlay code for 997; it is the sole geographic code for this region. However, due to the growing demand for telecommunication services, the IFT periodically reviews numbering resources. Users should note that the same seven-digit number may exist in different area codes, so it is essential to include the NDC for all calls outside the local area. For mobile numbers in this region, they are assigned under the non-geographic mobile codes (e.g., 1, 44, 45, etc.) and are not tied to area code 997.
Caller Instructions
- Local calls (within 997): Dial the seven-digit number directly.
- National long-distance calls (from other Mexican area codes): Dial 01 997 followed by the seven-digit number.
- International calls to 997: Dial your country's exit code (e.g., 011 from the US/Canada), then 52, then 997, then the seven-digit number.
- For calls from a mobile phone in Mexico: Simply dial 997 followed by the seven-digit number, as mobile networks automatically route long-distance calls without the 01 prefix.
This area code is used exclusively for fixed-line (PSTN) services, including traditional copper lines and some fixed wireless or VoIP services that are assigned geographic numbers. When calling from abroad, always verify the current dialing procedures with your service provider, as some carriers may require different prefixes.
