BOOKER prefixes in area code 806

NANPA records 4 assigned NXX blocks to rate center BOOKER 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), PANHANDLE TELECOMMUNICATION SYSTEMS, INC. - TX (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2004-03-18 and the most recent 2019-09-05. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
