How far area code 586 reaches
Area code 586 covers 11 rate centres, so two 586 numbers are not always a local call to each other.
A rate centre is a billing boundary rather than a postal one, which is why an area code can span several and a single city can contain many. It is also why the code alone cannot place a subscriber beyond a rough region.
Michigan is split across 12 area codes — 313, 248, 734, 989, 517, 586 and others. By allocated blocks 586 is the 6th largest of them, holding 9% of the Michigan total.
Where 586 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Mt Clemens is 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 586 number still reports the carrier it started with. Closing that gap needs a live query against the routing database. How line type is derived.
