The other area codes laid over 484
Area code 484 does not have Allentown to itself. 2 other codes — 610, 835 — serve 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.
Each holds its own blocks and its own carrier mix, so a 484 number and a 610 number from the same street can report different line types. Filtering Allentown by area code needs all 3 of them.
484 is not confined to Allentown itself: its blocks sit across 79 rate centres, named in the table below.

Where 484 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Phphsbzn30 and W Chester 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 484 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.

Where is area code 484?

Is a 484 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 484 the split runs 35% mobile, 49% landline and 16% VoIP, so landline is the most likely single answer.
Which carriers hold 484 numbers?
