Area code 505

Area code 505 serves New Mexico, including Albuquerque, Farmington and Santa Fe (Mountain time). It has been in service since January 1, 1947.

Numbers starting with 505 drew 1,461 reports to the FTC from Aug 14, 2026 to Nov 11, 2026 and 836 complaints to the FCC since November 2023. The number on your screen can be faked, so a 505 number proves nothing about where a call came from.

Phone companies holding 505 exchanges

Each exchange (the three digits after the area code) is assigned to one carrier. 65% of these exchanges are pooled: their numbers are handed out in blocks of 1,000 to other carriers, so the holder below is not always the company serving a given number.
