The towns inside area code 575
Area code 575 is not a city code. It covers 120 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 575 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
New Mexico is split across 2 area codes — 505, 575. By allocated blocks 575 is the second largest of them, holding 40% of the New Mexico total.
