New Mexico 505/575 Area Code Split

On October 7, 2007, the state of New Mexico will be split into two area codes. The northwest region of the state will retain its current area code (505), and the rest of the state will get a new area code (575). This change will apply to wireline and wireless service as well as other communications services.

Local calls within your area code will continue to be dialed with 7-digit dialing; local calls from one area code to another area code will require 10-digit dialing. All long-distance calls will require 1+10-digit dialing. Remember to use the new 575 area code as needed.
