Area code 274
Area code 274 is centred on Green Bay, Wisconsin. We hold 134 allocated blocks for it across 25 rate centres, split 53% mobile, 0% landline and 47% VoIP.
The other area codes laid over 274
Area code 274 does not have Green Bay to itself. 1 other code — 920 — 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.
9206,086 blocks, 126 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 274 number and a 920 number from the same street can report different line types. Filtering Green Bay by area code needs all 2 of them.
274 is not confined to Green Bay itself: its blocks sit across 25 rate centres, named in the table below.
Wisconsin is split across 8 area codes — 920, 608, 715, 262, 414, 274 and others. By allocated blocks 274 is the 7th largest of them, holding 0% of the Wisconsin total.

The largest holder, Onvoy, has 31% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 274 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 274?
Area code 274 covers Green Bay, Wisconsin. It is not the only code there: 920 is an overlay on the same rate centres, so a Green Bay, Wisconsin number can start with any of them.
Is a 274 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 274 the split runs 53% mobile, 0% landline and 47% VoIP, so mobile is the most likely single answer.
Which carriers hold 274 numbers?
The largest holders are Onvoy, T-Mobile Usa, Inc., Metro by T-Mobile. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 274 numbers are there?
The code holds 134 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 274 covers on the order of 134,000 possible numbers — most of which have never been issued to anyone.
