The other area codes laid over 816
Area code 816 does not have Kansas City, Missouri to itself. 1 other code — 975 — 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.
975186 blocks, 15 rate centres, mostly mobile
Each holds its own blocks and its own carrier mix, so a 816 number and a 975 number from the same street can report different line types. Filtering Kansas City, Missouri by area code needs all 2 of them.

Where 816 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why St Joseph and Blue Spg are 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 816?
Area code 816 covers Kansas City, Missouri. It is not the only code there: 975 is an overlay on the same rate centres, so a Kansas City, Missouri number can start with any of them.
Is a 816 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 816 the split runs 40% mobile, 46% landline and 13% VoIP, so landline is the most likely single answer.
Which carriers hold 816 numbers?
The largest holders are Southwestern Bell, Onvoy, 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 816 numbers are there?
The code holds 6,257 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 816 covers on the order of 6,257,000 possible numbers — most of which have never been issued to anyone.
