The towns inside area code 620
Area code 620 is not a city code. It covers 257 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 620 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.
Kansas is split across 4 area codes — 785, 620, 913, 316. By allocated blocks 620 is the second largest of them, holding 28% of the Kansas total.
Where 620 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Coffeyvl and Arkansascy 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 15% of the code.
These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 620 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 620?
Area code 620 is centred on Hutchinson, Kansas and spans 257 rate centres, so it covers a region rather than a town.
Is a 620 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 620 the split runs 34% mobile, 46% landline and 19% VoIP, so landline is the most likely single answer.
Which carriers hold 620 numbers?
The largest holders are Onvoy, Southwestern Bell, Verizon Wireless. That is the carrier the block was allocated to, which is not necessarily the network a given number sits on today.
How many 620 numbers are there?
The code holds 4,940 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 620 covers on the order of 4,940,000 possible numbers — most of which have never been issued to anyone.
