📍 Geographic Location of Morelos
Geographic Coverage and Administrative Jurisdiction
The area code 731 is a geographic National Destination Code (NDC) assigned to the state of Morelos, Mexico, under the ITU-T E.164 numbering plan. Morelos is located in south-central Mexico, bordering Mexico State to the north, Puebla to the east, and Guerrero to the south. The code 731 serves specific municipalities and localities within the state, primarily covering the northern and central regions. Key cities and towns within this code include Cuautla (a major urban center), Yecapixtla, Oaxtepec, Jonacatepec, and Tlayacapan. These areas are known for their historical significance, agricultural production, and growing residential communities. The administrative jurisdiction falls under the Federal Telecommunications Institute (IFT), which allocates and manages numbering resources.
Dialing Formats and Caller Instructions
For local callers within Mexico, dialing a number in the 731 area code requires the format: 731 XXX XXXX (10 digits total, including the area code). For international callers, the full international format is +52 731 XXX XXXX, where +52 is Mexico's country calling code. When calling from a mobile phone within Mexico, it is common to dial the 10-digit number directly. For callers outside Mexico, always replace the leading '0' (if used) with the international access prefix (e.g., 00 from many countries) followed by 52 and the area code and subscriber number.
Overlay and Numbering Considerations
As of the latest IFT updates, the 731 area code does not have an overlay code, meaning it is the sole NDC for its geographic region. However, due to increasing demand, some neighboring areas may adopt additional codes in the future. Subscriber numbers within 731 are 7 digits long, and the total number length is 10 digits (excluding the country code). It is important to note that while geographic area codes are traditionally associated with fixed-line PSTN services, they may also be used for VoIP and other fixed wireless services, but they are not assigned to mobile networks.
Practical Examples
- Local call (within Mexico): 731 123 4567
- International call (from USA): +52 731 123 4567
- International call (from Europe): 00 52 731 123 4567
When dialing from a Mexican mobile phone, it is not necessary to add a '1' before the area code, as was required in the past. Always verify the correct number with the recipient to avoid misdialing.
