The towns inside area code 810
Area code 810 is not a city code. It covers 50 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 810 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.
Michigan is split across 12 area codes — 313, 248, 734, 989, 517, 810 and others. By allocated blocks 810 is the 8th largest of them, holding 8% of the Michigan total.
Where 810 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why St Clair is shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, AT&T Wireless, has 14% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 810 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 810?
Area code 810 is centred on Flint, Michigan and spans 50 rate centres, so it covers a region rather than a town.
Is a 810 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 810 the split runs 45% mobile, 44% landline and 11% VoIP, so mobile is the most likely single answer.
Which carriers hold 810 numbers?
The largest holders are AT&T Wireless, Onvoy, Omnipoint Communications Midwest Operations, Llc. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 810 numbers are there?
The code holds 4,027 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 810 covers on the order of 4,027,000 possible numbers — most of which have never been issued to anyone.
