📍 Geographic Location of Durango
Overview of Area Code 674
Area code 674 is a geographic numbering plan area (NPA) assigned to the state of Durango, located in northwestern Mexico. It serves the capital city of Victoria de Durango and its surrounding metropolitan area, as well as several municipalities within the state. This code is part of the national numbering plan administered by the Instituto Federal de Telecomunicaciones (IFT) under the ITU-T E.164 standard for Mexico (country code +52).
Geographic Coverage and Administration
The 674 area code covers the central and southern regions of Durango, including the capital, Durango City, and nearby localities such as Gómez Palacio and Lerdo (though these cities are actually served by other area codes; the 674 primarily covers the capital and its immediate surroundings). The jurisdiction falls under the state of Durango, with the main urban center being the capital. The area is known for its historical significance, mining industry, and growing commercial activity.
Dialing Formats and Procedures
For local calls within the same area code, dial the 7-digit local number directly (e.g., 123 4567). For calls from other area codes within Mexico, dial the long-distance prefix '01' followed by the area code and local number: 01 674 123 4567. For international callers, dial Mexico's country code +52, then the area code and local number without the leading '01': +52 674 123 4567. Note that when dialing from a mobile phone within Mexico, it is common to use the international format (+52 674 123 4567) even for domestic calls.
Numbering and Overlay Considerations
Currently, area code 674 does not have an overlay; it is the sole area code serving the capital region. However, as demand for numbers grows, the IFT may introduce an overlay in the future, which would require 10-digit dialing for all local calls. At present, local calls within the area code can be made using 7 digits, but it is advisable to always use the full 10-digit format (area code + local number) to ensure compatibility with future changes.
Practical Information for Callers
When calling a Durango number from abroad, ensure you have the correct country code (+52) and drop any leading '0' from the area code. For example, a number in Durango City might be listed as (674) 123 4567 locally; internationally, dial +52 674 123 4567. If you are using VoIP services, the same international format applies. For emergency services within Durango, dial 911 as in the rest of Mexico.
