Area code 201
Area code 201 is centred on Hackensack, New Jersey. We hold 5,528 allocated blocks for it across 27 rate centres, split 33% mobile, 61% landline and 6% VoIP.
The other area codes laid over 201
Area code 201 does not have Hackensack to itself. 1 other code — 551 — 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.
5513,168 blocks, 23 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 201 number and a 551 number from the same street can report different line types. Filtering Hackensack by area code needs all 2 of them.
201 is not confined to Hackensack itself: its blocks sit across 27 rate centres, named in the table below.

Where 201 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Hasbrokhts is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

No carrier holds more than 12% of 201; the blocks are spread thin across many companies.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 201 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 201?
Area code 201 covers Hackensack, New Jersey. It is not the only code there: 551 is an overlay on the same rate centres, so a Hackensack, New Jersey number can start with any of them.
Is a 201 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 201 the split runs 33% mobile, 61% landline and 6% VoIP, so landline is the most likely single answer.
Which carriers hold 201 numbers?
The largest holders are Verizon New Jersey, Inc., Verizon Wireless, Mcimetro Access Transmission Services Llc. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 201 numbers are there?
The code holds 5,528 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 201 covers on the order of 5,528,000 possible numbers — most of which have never been issued to anyone.
