The towns inside area code 207
Area code 207 is not a city code. It covers 249 separate rate centres — billing areas, each its own local calling zone. The largest of them are named in the table below.
That matters twice over. A call between two 207 numbers is not necessarily a local call, because they can sit in different rate centres. And a code this wide narrows a subscriber to a region rather than a town.
207 is the only area code whose numbers sit mainly in Maine. Every Maine number therefore starts 207 unless it was issued in a border rate centre billed to a neighbouring code.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 207 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 207?
Area code 207 is centred on Portland, Maine and spans 249 rate centres, so it covers a region rather than a town.
Is a 207 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 207 the split runs 37% mobile, 55% landline and 8% VoIP, so landline is the most likely single answer.
Which carriers hold 207 numbers?
The largest holders are Consolidated Comm Of No. New England, AT&T Wireless, Bell Atlantic Mobile, Inc. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 207 numbers are there?
The code holds 6,243 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 207 covers on the order of 6,243,000 possible numbers — most of which have never been issued to anyone.
