The other area codes laid over 304
Area code 304 does not have Charleston, West Virginia to itself. 1 other code — 681 — 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.
6814,379 blocks, 213 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 304 number and a 681 number from the same street can report different line types. Filtering Charleston, West Virginia by area code needs all 2 of them.

Where 304 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Hntngtnzn1 and Prkrsbgzn1 are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

Common questions
Where is area code 304?
Area code 304 covers Charleston, West Virginia. It is not the only code there: 681 is an overlay on the same rate centres, so a Charleston, West Virginia number can start with any of them.
Is a 304 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 304 the split runs 41% mobile, 54% landline and 5% VoIP, so landline is the most likely single answer.
Which carriers hold 304 numbers?
The largest holders are AT&T Wireless, Frontier West Virginia Inc., Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 304 numbers are there?
The code holds 5,718 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 304 covers on the order of 5,718,000 possible numbers — most of which have never been issued to anyone.
