The other area codes laid over 817
Area code 817 does not have Arlington to itself. 1 other code — 682 — serves the same rate centres, laid over the same ground rather than dividing it. That is an overlay: a new code added when the old one ran out of numbers, covering the same streets. Two neighbours can hold different area codes, so the code says roughly when a number was issued rather than where it sits.
6824,345 blocks, 23 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 817 number and a 682 number from the same street can report different line types. Filtering Arlington by area code needs all 2 of them.

The largest holder, Southwestern Bell, has 22% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 817 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 817?
Area code 817 covers Arlington, Texas. It is not the only code there: 682 is an overlay on the same rate centres, so a Arlington, Texas number can start with any of them.
Is a 817 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 817 the split runs 36% mobile, 55% landline and 8% VoIP, so landline is the most likely single answer.
Which carriers hold 817 numbers?
The largest holders are Southwestern Bell, Onvoy, AT&T Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 817 numbers are there?
The code holds 5,343 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 817 covers on the order of 5,343,000 possible numbers — most of which have never been issued to anyone.
