US area codes

Every one of the 367 US area codes we hold numbering data for, with the centre it is built around, whether its numbers skew mobile, landline or VoIP, and how many allocated blocks sit inside it — 1,512,721 in total.

What the columns mean

Main centre

The rate centre holding the most blocks in that code. An area code usually spans many; this is where its centre of gravity is.

Mostly

Which line type holds the most blocks. In North America mobile and landline share the same ranges, so this is a tendency rather than a rule — it cannot tell you what any single number is.

Blocks

Allocated blocks of 1,000 or 10,000 consecutive numbers. An unallocated block cannot ring, which is most of what a validator is for.

Line type and centre come from the block's original allocation. A ported number keeps its block, so it still reports the carrier it started with. Check a single number or a whole list.
