505 first assigned
505 came first, in 1947
505 was New Mexico's original area code, assigned in 1947. The newest, 575, arrived in 2007. Each of the 2 codes below maps to its own part of the state, so the code you pick shows which region you serve.
01 — New Mexico at a Glance
New Mexico, by the numbers.
Area code 505 was assigned in 1947 and served all of New Mexico — Albuquerque, Santa Fe, Las Cruces, Roswell — for sixty years.
By the mid-2000s, Albuquerque's growth and rising cellphone use pushed 505's number supply toward exhaustion.
On October 7, 2007, New Mexico split for the first time: 505 kept the northwest, including Albuquerque and Santa Fe, while new code 575 took the south and southeast.
That split remains in place today, giving New Mexico just two area codes along a north-south line.
Did you know?
When New Mexico finally split its single area code in 2007, the new 575 code ended up covering more land area than 505, even though 505 kept the state's largest city, Albuquerque.

Dialing
Since October 24, 2021, every local call in New Mexico has to be dialed with the area code, in both 505 and 575. They were on the FCC's list of 82 area codes that moved to mandatory ten-digit local dialing because of the new 988 lifeline code. Phone numbers themselves did not change.
Area code status
New Mexico has two area codes that divide the state geographically rather than overlay each other: 505 and 575. 575 was split from 505 on October 7, 2007. We did not find an announced overlay or relief plan after that split.
Good to know
