Area code 505 covers northwestern and north-central New Mexico, including cities such as Albuquerque, Santa Fe, Farmington, and Gallup. Established in 1947 as one of the original area codes, it originally served the entire state. In 2007, the eastern and southern portions of the state were split off into area code 575. Today, 505 continues to serve the state’s most populous and economically significant areas. It includes major government facilities, Native American communities, and cultural hubs. 505 is a highly recognized code in New Mexico, frequently referenced in local branding and pride campaigns. It symbolizes the heart of the Land of Enchantment.
