Where New Mexico area codes came from

For 60 years, 505 covered New Mexico on its own, until 575 opened in 2007.

1. 1947: 505 was among the original area codes issued in 1947, serving Abiquiu, Albuquerque and Aztec.
2. 2007: 575 was split off from 505 to serve Alamogordo, Alto and Angel Fire.

Making calls in New Mexico
