- 3. The seven-digit local number.

Why New Mexico has multiple area codes
New Mexico has no overlays; the state is split geographically between two area codes.
When a region runs low on available numbers, the phone system adds capacity in one of two ways. A split divides the old region geographically and gives part of it a brand-new area code. An overlay keeps the existing code and layers a second one on top of the same area, which is why a single city can have several area codes and why ten-digit dialing becomes the norm. Either way, the number you dial always stays the same length: +1, the area code, then seven digits.
