The other area codes laid over 973
Area code 973 does not have Newark to itself. 1 other code — 862 — 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.
8624,002 blocks, 40 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 973 number and a 862 number from the same street can report different line types. Filtering Newark by area code needs all 2 of them.

Where 973 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Mt View and Little Fls are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.
