The area code 575 is located in Alamogordo, New Mexico.
Area code 575 serves most of New Mexico outside the Albuquerque metro, including Alamogordo, New Mexico, in the Tularosa Basin at the base of the Sacramento Mountains. Introduced in 2007 as a split from 505, this New Mexico area code covers wide-open desert, mountain towns, and key highways like US‑70 and US‑54. It supports local phone numbers for homes, businesses, schools, and military sites across southern and eastern New Mexico. The region follows Mountain Time (MT) and includes some of the state’s most visited landmarks.
Major cities and communities in the 575 area code include:
In and around Alamogordo, 575 connects callers to White Sands National Park, Holloman Air Force Base, the New Mexico Museum of Space History, Lincoln National Forest, and the White Sands Missile Range. It is one of New Mexico’s two area codes, alongside 505, making 575 essential for calling much of rural and southern New Mexico. The code’s footprint reaches from borderland cities to oil-and-gas hubs and farming communities, giving 575 phone numbers a strong regional identity tied to space history, the desert, and outdoor adventure.
