COLLBRAN prefixes in area code 970
NANPA records 4 assigned NXX blocks to rate center COLLBRAN in area code 970, 0.5% 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. 2 holders hold those blocks, the largest being ONVOY, LLC - CO (3), CENTURYTEL OF EAGLE, INC. DBA CENTURYLINK (1). The earliest assignment on record here is 2007-07-09 and the most recent 2026-10-16. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
