2 area codes currently serve New Mexico. The state's numbering history begins in 1947 with 505. Most recent addition: 575, in service since 2007.

Coverage runs through 505 (Albuquerque), 575 (Las Cruces); prefix counts in the table approximate each code's numbering footprint.

Time zone is uniform across the state's codes: Mountain.

505 has served Albuquerque since 1947, carries 682 active prefixes across 34 rate centers, split among 46 carriers. 445 of its prefixes are pooled — shared between carriers in thousands-number blocks. It is the oldest area code in New Mexico, in service since 1947. NANPA projects its capacity to last until 3Q 2031. Local dialing is ten digits.

575 has served Las Cruces since 2007, carries 521 active prefixes across 120 rate centers, split among 49 carriers. 327 of its prefixes are pooled — shared between carriers in thousands-number blocks. NANPA projects its capacity to last until 3Q 2051 — no relief needed for decades. It was created from 505. Local dialing is ten digits.

Toll-free callers are a separate story: 800-family numbers carry no New Mexico geography at all, so an 833 or 877 number is never "from" the state — it belongs to whichever business rents it, anywhere in the NANP.

A number in any of these codes was issued in New Mexico, but portability means its owner may be anywhere today — the codes locate numbers, not people. To dig further, open a code's prefix or cities pages.
