The towns inside area code 906
Area code 906 is not a city code. It covers 93 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 906 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, 906 and others. By allocated blocks 906 is the 12th largest of them, holding 3% of the Michigan total.
Where 906 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Iron Mt and St Ignace are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

The largest holder, Onvoy, has 20% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 906 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 906?
Area code 906 is centred on Marquette, Michigan and spans 93 rate centres, so it covers a region rather than a town.
Is a 906 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 906 the split runs 27% mobile, 65% landline and 7% VoIP, so landline is the most likely single answer.
Which carriers hold 906 numbers?
The largest holders are Onvoy, Michigan Bell Tel Co, 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 906 numbers are there?
The code holds 1,757 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 906 covers on the order of 1,757,000 possible numbers — most of which have never been issued to anyone.
