History of Area Code 505
Area code 505 was one of the original area codes assigned under the North American Numbering Plan in 1947. It originally covered the entire state of New Mexico, making it an original geographic area code.
New Mexico created area code 575 through a geographic split of 505 in 2007. The split took effect on October 7, 2007, and left 505 in Albuquerque and many northern and central communities while 575 covered most of the rest of the state. Area code 505 is not an overlay, so another area code does not cover the same region as a general overlay.
