Area code 414
Area code 414 covers Milwaukee. We hold 3,936 allocated blocks for it across 4 rate centres, split 49% mobile, 43% landline and 9% VoIP.
How far area code 414 reaches
Area code 414 covers 4 rate centres, so two 414 numbers are not always a local call to each other.
A rate centre is a billing boundary rather than a postal one, which is why an area code can span several and a single city can contain many. It is also why the code alone cannot place a subscriber beyond a rough region.
Wisconsin is split across 8 area codes — 920, 608, 715, 262, 414, 534 and others. By allocated blocks 414 is the 5th largest of them, holding 14% of the Wisconsin total.

The largest holder, United States Cellular, has 12% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 414 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 414?
Area code 414 covers Milwaukee, spanning 4 rate centres.
Is a 414 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 414 the split runs 49% mobile, 43% landline and 9% VoIP, so mobile is the most likely single answer.
Which carriers hold 414 numbers?
The largest holders are United States Cellular, Wisconsin Bell Inc, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 414 numbers are there?
The code holds 3,936 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 414 covers on the order of 3,936,000 possible numbers — most of which have never been issued to anyone.
