The towns inside area code 734
Area code 734 is not a city code. It covers 33 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 734 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, 586 and others. By allocated blocks 734 is the third largest of them, holding 11% of the Michigan total.

The largest holder, Verizon Wireless, has 17% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 734 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 734?
Area code 734 is centred on Ann Arbor, Michigan and spans 33 rate centres, so it covers a region rather than a town.
Is a 734 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 734 the split runs 44% mobile, 46% landline and 10% VoIP, so landline is the most likely single answer.
Which carriers hold 734 numbers?
The largest holders are Verizon Wireless, Onvoy, Michigan Bell Tel Co. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 734 numbers are there?
