BERTHOUD prefixes in area code 970

NANPA records 8 assigned NXX blocks to rate center BERTHOUD in area code 970, 1.0% 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. 7 holders hold those blocks, the largest being AMERICAN MESSAGING SERVICES, LLC (2), LEVEL 3 COMMUNICATIONS, LLC - CO (1), PEERLESS NETWORK OF COLORADO, LLC - CO (1). The earliest assignment on record here is 2004-10-27 and the most recent 2024-03-28. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
