The towns inside area code 505
Area code 505 is not a city code. It covers 34 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 505 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 505 is the largest of them by a wide margin, holding 60% of the New Mexico total.

The largest holder, Verizon Wireless, has 18% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 505 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Common questions
Where is area code 505?
Area code 505 is centred on Albuquerque, New Mexico and spans 34 rate centres, so it covers a region rather than a town.
Is a 505 number a mobile or a landline?
It can be either, and the digits do not say which. North American mobile and landline numbers share the same ranges, so the answer comes from the carrier holding the block. In 505 the split runs 53% mobile, 32% landline and 16% VoIP, so mobile is the most likely single answer.
Which carriers hold 505 numbers?
The largest holders are Verizon Wireless, AT&T Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 505 numbers are there?
The code holds 5,009 allocated blocks in our copy of the numbering plan. A block is 1,000 or 10,000 consecutive numbers depending on how deeply it has been pooled, so 505 covers on the order of 5,009,000 possible numbers — most of which have never been issued to anyone.
