History of Area Code 575
Area code 575 was created on October 7, 2007. It was split from area code 505, which had covered the entire state of New Mexico since 1947. After the split, 505 remained in the Albuquerque, Santa Fe, Farmington, and Gallup areas, and 575 served the rest of the state.
Area code 575 is a split area code, not an overlay. Public records from the New Mexico Public Regulation Commission and the North American Numbering Plan show that the change was made because the 505 area was running short of available phone numbers. No overlay has been introduced for 575.
