The towns inside area code 856
Area code 856 is not a city code. It covers 32 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 856 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.
New Jersey is split across 10 area codes — 609, 732, 856, 201, 908, 973 and others. By allocated blocks 856 is the third largest of them, holding 13% of the New Jersey total.
Where 856 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Merchantvl and Haddon Hts 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 13% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 856 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 856?
Area code 856 is centred on Camden, New Jersey and spans 32 rate centres, so it covers a region rather than a town.
Is a 856 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 856 the split runs 36% mobile, 44% landline and 20% VoIP, so landline is the most likely single answer.
Which carriers hold 856 numbers?
The largest holders are Onvoy, AT&T Wireless, T-Mobile USA, Inc.. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 856 numbers are there?
The code holds 5,719 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 856 covers on the order of 5,719,000 possible numbers — most of which have never been issued to anyone.
