Area code 430
Area code 430 is centred on Longview, Texas. We hold 2,262 allocated blocks for it across 158 rate centres, split 31% mobile, 33% landline and 37% VoIP.
The other area codes laid over 430
Area code 430 does not have Longview to itself. 1 other code — 903 — 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.
9035,642 blocks, 194 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 430 number and a 903 number from the same street can report different line types. Filtering Longview by area code needs all 2 of them.
430 is not confined to Longview itself: its blocks sit across 158 rate centres, named in the table below.
Texas is split across 28 area codes — 346, 832, 469, 210, 956, 430 and others. By allocated blocks 430 is the 27th largest of them, holding 2% of the Texas total.
Where 430 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 430 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 430?
Area code 430 covers Longview, Texas. It is not the only code there: 903 is an overlay on the same rate centres, so a Longview, Texas number can start with any of them.
Is a 430 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 430 the split runs 31% mobile, 33% landline and 37% VoIP, so VoIP is the most likely single answer.
Which carriers hold 430 numbers?
The largest holders are Onvoy, AT&T Wireless, Onvoy Spectrum. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 430 numbers are there?
The code holds 2,262 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 430 covers on the order of 2,262,000 possible numbers — most of which have never been issued to anyone.
