CALHAN prefixes in area code 719
NANPA records 6 assigned NXX blocks to rate center CALHAN in area code 719, 0.9% 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. 4 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CO (2), ONVOY, LLC - CO (2), QWEST CORPORATION (1). The earliest assignment on record here is 2012-11-07 and the most recent 2023-08-31. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
