📍 Geographic Location of Tabasco
Geographic Coverage and Administrative Jurisdiction
The Mexican area code 917 is a geographic National Destination Code (NDC) assigned to the southeastern state of Tabasco. Under the ITU-T E.164 international numbering plan, the full country calling code for Mexico is +52, so numbers in this region are dialed internationally as +52 917 XXX XXXX. Within Tabasco, the 917 code serves a mix of municipal seats and rural communities, with the largest concentration of subscribers in the state capital, Villahermosa, and its surrounding metropolitan area. The code also covers towns such as Cárdenas, Comalcalco, Paraíso, and Huimanguillo, reflecting the state's economic hubs in the petroleum and agricultural sectors.
Dialing Formats and Caller Instructions
For local callers within the 917 area, the standard national dialing format is 917 XXX XXXX (ten digits total, omitting the trunk prefix '0' and the country code). However, if you are calling from another area code within Mexico, you must dial the long-distance prefix 0 followed by the area code and the local number: 0 917 XXX XXXX. International callers from outside Mexico should dial their international access prefix (e.g., 011 from the US/Canada, 00 from most European countries) followed by 52, then 917, and the seven-digit local number: +52 917 XXX XXXX. Remember to drop any leading '0' when dialing from abroad.
Overlay and Numbering Considerations
Currently, the 917 area code does not have an overlay code; it is the sole geographic code for this part of Tabasco. However, the Mexican Federal Telecommunications Institute (IFT) periodically reviews numbering resources, and future overlays are possible as demand grows. Subscribers in the 917 region can keep their numbers when switching between fixed-line operators, thanks to local number portability regulations. For VoIP users, the same geographic number can be used, but emergency services (911) and certain short codes may require a registered physical address to ensure proper routing.
Practical Examples for Businesses and Travelers
If you are a business establishing a presence in Tabasco, obtaining a 917 number reinforces a local identity and can reduce long-distance costs for customers within the state. For travelers, always verify the local dialing rules: when roaming with a foreign SIM, you must use the international format +52 917 XXX XXXX. When using a Mexican SIM, you can dial the ten-digit national format. Understanding these nuances ensures seamless communication in this vibrant region.
