The towns inside area code 863
Area code 863 is not a city code. It covers 22 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 863 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.
Florida is split across 23 area codes — 786, 904, 561, 813, 352, 863 and others. By allocated blocks 863 is the 12th largest of them, holding 5% of the Florida total.
Where 863 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Winter Hvn and Zolfo Spg are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 863 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 863?
Area code 863 is centred on Lakeland, Florida and spans 22 rate centres, so it covers a region rather than a town.
Is a 863 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 863 the split runs 50% mobile, 33% landline and 17% VoIP, so mobile is the most likely single answer.
Which carriers hold 863 numbers?
The largest holders are Onvoy, T-Mobile USA, Inc., 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 863 numbers are there?
The code holds 4,141 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 863 covers on the order of 4,141,000 possible numbers — most of which have never been issued to anyone.
