ESTES PARK prefixes in area code 970

NANPA records 6 assigned NXX blocks to rate center ESTES PARK in area code 970, 0.8% of the 786 blocks assigned in the code. A rate center is the billing geography a block is allocated to – NANPA truncates the name to ten characters, so read it as a NANPA label rather than a town. 5 holders hold those blocks, the largest being QWEST CORPORATION (2), ELECTRIC LIGHTWAVE LLC DBA ALLSTREAM (1), BANDWIDTH.COM CLEC, LLC - CO (1). The earliest assignment on record here is 2009-10-07 and the most recent 2022-02-18. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 748 – overlay codes cover the same geography, so a rate center is served by all of them.
