The other area codes laid over 458
Area code 458 does not have Eugene to itself. 1 other code — 541 — 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.
5415,769 blocks, 191 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 458 number and a 541 number from the same street can report different line types. Filtering Eugene by area code needs all 2 of them.

Where 458 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Klamathfls and Junctioncy 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 458 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 458?
Area code 458 covers Eugene, Oregon. It is not the only code there: 541 is an overlay on the same rate centres, so a Eugene, Oregon number can start with any of them.
Is a 458 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 458 the split runs 43% mobile, 27% landline and 30% VoIP, so mobile is the most likely single answer.
Which carriers hold 458 numbers?
The largest holders are Onvoy, AT&T Wireless, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
