DALHART prefixes in area code 806

NANPA records 6 assigned NXX blocks to rate center DALHART in area code 806, 0.8% 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. 4 holders hold those blocks, the largest being XIT TELECOMMUNICATIONS & TECHNOLOGY, INC. - TX (2), VALOR TELECOMM TX, LP-TX #1 DBA WINDSTREAM COMM SW (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (1). The earliest assignment on record here is 2003-04-03 and the most recent 2016-07-25. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
