FRITCH prefixes in area code 806

NANPA records 4 assigned NXX blocks to rate center FRITCH 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, LD-TX #2 DBA WINDSTREAM COMM SW (2), LEVEL 3 COMMUNICATIONS, LLC - TX (1), ONVOY, LLC - TX (1). The earliest assignment on record here is 2007-07-27 and the most recent 2017-11-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
