The towns inside area code 928
Area code 928 is not a city code. It covers 94 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 928 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.
Arizona is split across 5 area codes — 480, 520, 602, 928, 623. By allocated blocks 928 is the 4th largest of them, holding 20% of the Arizona total.
Where 928 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Bullheadcy and Lkhavasucy are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 928 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 928?
Area code 928 is centred on Yuma, Arizona and spans 94 rate centres, so it covers a region rather than a town.
Is a 928 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 928 the split runs 40% mobile, 44% landline and 16% VoIP, so landline is the most likely single answer.
Which carriers hold 928 numbers?
The largest holders are Onvoy, Verizon Wireless, Qwest Corporation. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 928 numbers are there?
The code holds 4,620 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 928 covers on the order of 4,620,000 possible numbers — most of which have never been issued to anyone.
