The towns inside area code 970
Area code 970 is not a city code. It covers 120 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 970 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.
Colorado is split across 5 area codes — 720, 970, 719, 303, 983. By allocated blocks 970 is the second largest of them, holding 26% of the Colorado total.
Where 970 numbers are concentrated
NANPA truncates rate-centre names to ten characters and drops the spaces, which is why Ft Collins and Grand Jct are shortened. Names are reproduced as recorded rather than expanded — the abbreviation is the key the block data is filed under.

These are original allocations. A number keeps its digits and its block when its subscriber moves network, so a ported 970 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 970?
Area code 970 is centred on Fort Collins, Colorado and spans 120 rate centres, so it covers a region rather than a town.
Is a 970 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 970 the split runs 32% mobile, 45% landline and 22% VoIP, so landline is the most likely single answer.
Which carriers hold 970 numbers?
The largest holders are Onvoy, Qwest Corporation, 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 970 numbers are there?
The code holds 5,598 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 970 covers on the order of 5,598,000 possible numbers — most of which have never been issued to anyone.
