Area code 920 is centred on Green Bay, Wisconsin. We hold 6,086 allocated blocks for it across 126 rate centres, split 44% mobile, 45% landline and 11% VoIP.
The other area codes laid over 920
Area code 920 does not have Green Bay to itself. 1 other code — 274 — 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.
274134 blocks, 25 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 920 number and a 274 number from the same street can report different line types. Filtering Green Bay by area code needs all 2 of them.
920 is not confined to Green Bay itself: its blocks sit across 126 rate centres, named in the table below.

Where 920 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Ltl Chute is 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 920 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 920?
Area code 920 covers Green Bay, Wisconsin. It is not the only code there: 274 is an overlay on the same rate centres, so a Green Bay, Wisconsin number can start with any of them.
Is a 920 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 920 the split runs 44% mobile, 45% landline and 11% VoIP, so landline is the most likely single answer.
Which carriers hold 920 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.
How many 920 numbers are there?
The code holds 6,086 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 920 covers on the order of 6,086,000 possible numbers — most of which have never been issued to anyone.
