📍 Geographic Location of Tabasco
Geographic Coverage and Administrative Jurisdiction
The area code 936 is a geographic National Destination Code (NDC) assigned to the southeastern Mexican state of Tabasco. This code serves the central and eastern portions of the state, encompassing the capital city of Villahermosa and its surrounding metropolitan area. Administratively, the code falls under the jurisdiction of the Federal Telecommunications Institute (IFT), which oversees numbering resources in accordance with the ITU-T E.164 international standard. The 936 region covers key municipalities including Centro (Villahermosa), Jalapa, Teapa, and parts of Tacotalpa, providing PSTN and VoIP services to residential, commercial, and government subscribers.
Primary Cities and Local Dialing
The principal city served by 936 is Villahermosa, the state capital and economic hub of Tabasco. Other notable localities include Teapa, known for its ecotourism, and Jalapa, a smaller urban center. Within Mexico, local calls between numbers sharing the 936 code are dialed using the seven-digit subscriber number only, without the area code. For example, to call a local landline in Villahermosa, one would dial 123-4567 (where 123-4567 represents the local number). This format applies to both fixed-line and VoIP services that are assigned geographic numbers within the 936 NDC.
International Dialing Format
For callers outside Mexico, the international format requires the country code, area code, and subscriber number. To reach a number in the 936 region from abroad, dial +52 936 123 4567. The plus sign represents the international access prefix, which varies by country (e.g., 011 from the United States and Canada). When dialing from a mobile phone, the plus sign is typically used to initiate the call. It is important to note that Mexican numbers are generally 10 digits long after the country code, and the area code is an integral part of the national numbering plan.
Overlay and Numbering Considerations
As of the latest IFT updates, the 936 area code does not have an overlay code; it is the sole geographic code for its service area. However, due to growing demand, the IFT periodically reviews numbering resources. Subscribers in the region may have the option to retain their numbers when switching between fixed-line carriers, a process known as local number portability. This applies to both geographic and non-geographic services, ensuring that end-users can change providers without changing their published number.
Caller Instructions
For local callers within the 936 area, dialing the seven-digit number is sufficient. For long-distance calls from other parts of Mexico, dial the national long-distance prefix 01 followed by the area code and number: 01 936 123 4567. International callers should always use the full international format to avoid misrouting. It is also advisable to confirm the correct number length and format with the called party, especially when dealing with VoIP or mobile services that may have different routing characteristics.
