Area code 540 is centred on Roanoke, Virginia. We hold 6,729 allocated blocks for it across 117 rate centres, split 44% mobile, 40% landline and 16% VoIP.
The other area codes laid over 540
Area code 540 does not have Roanoke to itself. 1 other code — 826 — 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.
826817 blocks, 69 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 540 number and a 826 number from the same street can report different line types. Filtering Roanoke by area code needs all 2 of them.
540 is not confined to Roanoke itself: its blocks sit across 117 rate centres, named in the table below.

The largest holder, Verizon Wireless, 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 540 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 540?
Area code 540 covers Roanoke, Virginia. It is not the only code there: 826 is an overlay on the same rate centres, so a Roanoke, Virginia number can start with any of them.
Is a 540 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 540 the split runs 44% mobile, 40% landline and 16% VoIP, so mobile is the most likely single answer.
Which carriers hold 540 numbers?
The largest holders are Verizon Wireless, Onvoy, Verizon Virginia, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 540 numbers are there?
The code holds 6,729 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 540 covers on the order of 6,729,000 possible numbers — most of which have never been issued to anyone.
