Area code 947
Area code 947 covers Ortonville, Michigan. We hold 2,243 allocated blocks for it across 20 rate centres, split 72% mobile, 18% landline and 10% VoIP.
The other area codes laid over 947
Area code 947 does not have Ortonville to itself. 1 other code — 248 — 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.
2485,471 blocks, 21 rate centres, mostly landline
Each holds its own blocks and its own carrier mix, so a 947 number and a 248 number from the same street can report different line types. Filtering Ortonville by area code needs all 2 of them.
947 is not confined to Ortonville itself: its blocks sit across 20 rate centres, named in the table below.

Where 947 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Milfdwh Lk and Auburn Hts are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

Verizon Wireless alone holds 37% of every block in 947, which is unusually concentrated for an area code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 947 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 947?
Area code 947 covers Ortonville, Michigan. It is not the only code there: 248 is an overlay on the same rate centres, so a Ortonville, Michigan number can start with any of them.
Is a 947 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 947 the split runs 72% mobile, 18% landline and 10% VoIP, so mobile is the most likely single answer.
Which carriers hold 947 numbers?
The largest holders are Verizon Wireless, AT&T Wireless, Onvoy. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 947 numbers are there?
The code holds 2,243 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 947 covers on the order of 2,243,000 possible numbers — most of which have never been issued to anyone.
