Area Code 95 – Oaxaca

Overview of Area Code 95 in Oaxaca, Mexico

Area code 95 is a geographic National Destination Code (NDC) assigned to the state of Oaxaca, located in southern Mexico. Under the ITU-T E.164 numbering plan, the full international dialing format for numbers in this region is +52 95 XXX XXXX, where +52 is the Mexico country calling code, 95 is the NDC, and the remaining seven digits constitute the subscriber number. This area code serves the central valleys and the capital city of Oaxaca de Juárez, along with surrounding municipalities such as Santa Cruz Xoxocotlán, San Antonio de la Cal, and Tlalixtac de Cabrera. The region is a major cultural and tourist destination, known for its colonial architecture, indigenous heritage, and the famous Guelaguetza festival.

Dialing Formats and Caller Instructions

For local callers within Mexico, dialing a number in area code 95 requires the national trunk prefix 01 followed by the area code and the seven-digit local number: 01 95 XXX XXXX. For example, to call a landline in Oaxaca City from elsewhere in Mexico, you would dial 01 95 123 4567. International callers must use the country code +52, omitting the trunk prefix: +52 95 123 4567. When calling from a mobile phone within Mexico, it is also common to dial +52 95 XXX XXXX directly, as the Mexican numbering plan now allows uniform dialing for both national and international calls.

Geographic Coverage and Overlay Considerations

Area code 95 is a geographic code that covers the central region of Oaxaca state, including the capital and its metropolitan area. It is one of several area codes serving Oaxaca; other regions of the state use different NDCs such as 951 (which actually covers the same capital area) and 954 for the Istmo de Tehuantepec region. Notably, Oaxaca City is one of the few places in Mexico where multiple area codes (95 and 951) serve the same geographic area, which can lead to confusion. This is not an overlay in the traditional sense but rather a legacy of numbering plan expansions. As a result, callers must be aware that both 95 and 951 are valid for the same region, and the correct code depends on the specific subscriber's number.

For businesses and residents in the 95 area, it is essential to ensure that all published numbers include the full national or international format to avoid misdialing. The Mexican telecom regulator (IFT) has been promoting the use of the +52 country code for all calls, including domestic ones, to simplify dialing and support number portability.

Regulatory and Technical Notes

Area code 95 is allocated to fixed-line services, including PSTN and VoIP, and is managed by various local exchange carriers. As with all Mexican geographic numbers, the subscriber number is seven digits long, and the total length of a national significant number (NSN) is ten digits (excluding the trunk prefix). The numbering plan is closed, meaning that all digits must be dialed for any call to complete. Number portability is available in Mexico, allowing users to retain their numbers when switching service providers, but the geographic area code remains associated with the original location.
