The other area codes laid over 903
Area code 903 does not have Tyler to itself. 1 other code — 430 — 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.
4302,262 blocks, 158 rate centres, mostly VoIP
Each holds its own blocks and its own carrier mix, so a 903 number and a 430 number from the same street can report different line types. Filtering Tyler by area code needs all 2 of them.
903 is not confined to Tyler itself: its blocks sit across 194 rate centres, named in the table below.

Where 903 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Sulphurspg and Jacksonvl 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 903 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 903?
Area code 903 covers Tyler, Texas. It is not the only code there: 430 is an overlay on the same rate centres, so a Tyler, Texas number can start with any of them.
Is a 903 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 903 the split runs 43% mobile, 47% landline and 10% VoIP, so landline is the most likely single answer.
Which carriers hold 903 numbers?
The largest holders are AT&T Wireless, Verizon 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 903 numbers are there?
The code holds 5,642 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 903 covers on the order of 5,642,000 possible numbers — most of which have never been issued to anyone.
