Area code 656
Area code 656 covers Tampa, Florida. We hold 1,020 allocated blocks for it across 7 rate centres, split 47% mobile, 2% landline and 50% VoIP.
The other area codes laid over 656
Area code 656 does not have Tampa, Florida to itself. 1 other code — 813 — 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.
8135,933 blocks, 8 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 656 number and a 813 number from the same street can report different line types. Filtering Tampa, Florida by area code needs all 2 of them.

Where 656 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Tampacen is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

Common questions
Where is area code 656?
Area code 656 covers Tampa, Florida. It is not the only code there: 813 is an overlay on the same rate centres, so a Tampa, Florida number can start with any of them.
Is a 656 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 656 the split runs 47% mobile, 2% landline and 50% VoIP, so VoIP is the most likely single answer.
Which carriers hold 656 numbers?
The largest holders are Onvoy, Verizon Wireless, AT&T Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 656 numbers are there?
