NANP area code 505, Telephone prefix in New Mexico, US
NANP area code 505 is a telephone prefix serving the northwestern and central parts of New Mexico, including Albuquerque, Santa Fe, Gallup, and Farmington. The code covers urban centers and rural communities across a large portion of the state.
The North American Numbering Plan assigned area code 505 to New Mexico in 1947, making it one of the original telephone prefixes in the United States. In 2007, a new area code 575 was introduced for less populated areas, while 505 remained in use for the larger cities.
The number 505 functions as a regional identifier across New Mexico, appearing in business names, local products, and community organizations throughout the state.
Callers in this region must dial ten digits for all local calls since the introduction of the national 988 hotline. Visitors should always include the full area code when calling local numbers, even when within the same coverage zone.
Many businesses and brands across the region deliberately incorporate the digit sequence into their names as a marker of local identity. This practice grew after the numbering split, when 505 became associated specifically with the higher population centers.
