The 505 numbering plan area covers the northwestern and central portions of New Mexico. Originally established in October 1947, it served the entire state until October 7, 2007, when it was reduced in size due to increasing demand for telecommunication services.
Area code 505 was originally the sole area code for New Mexico. On October 7, 2007, the state was split, and area code 575 was introduced to serve the rest of New Mexico, with 505 remaining in the northwestern and central parts. Prior to October 24, 2021, the 505 area code transitioned to ten-digit dialing due to the nationwide designation of 988 as a dialing code for the National Suicide Prevention Lifeline, which conflicted with existing central office codes.
Area code 505 is a General Purpose Code which was placed in service on January 1, 1947.
Our reverse phone lookup will analyze the three-digit prefix of any 505 area code phone number and will show which telecommunications company and rate center it was initially assigned to. This prefix code data may help to determine the U.S. carrier, New Mexico geographic region, and local calling area associated with the phone number.
