BRISTOGRND prefixes in area code 719

NANPA records 3 assigned NXX blocks to rate center BRISTOGRND in area code 719, 0.5% of the 665 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. 3 holders hold those blocks, the largest being ONVOY, LLC - CO (1), CENTURYTEL OF EAGLE, INC. DBA CENTURYLINK (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2007-07-13 and the most recent 2022-01-13. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
