Area code 610
Area code 610 is centred on Allentown, Pennsylvania. We hold 4,916 allocated blocks for it across 90 rate centres, split 29% mobile, 64% landline and 7% VoIP.
The other area codes laid over 610
Area code 610 does not have Allentown to itself. 2 other codes — 484, 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 610 number and a 484 number from the same street can report different line types. Filtering Allentown by area code needs all 3 of them.
610 is not confined to Allentown itself: its blocks sit across 90 rate centres, named in the table below.

Where 610 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Phphsbzn30 and Phphsbzn28 are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

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 610 the split runs 29% mobile, 64% landline and 7% VoIP, so landline is the most likely single answer.
