DENVERCITY prefixes in area code 806

NANPA records 4 assigned NXX blocks to rate center DENVERCITY in area code 806, 0.5% of the 734 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 VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1), BANDWIDTH.COM CLEC, LLC - TX (1). The earliest assignment on record here is 2002-06-19 and the most recent 2015-02-18. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
