TUCKERMAN prefixes in area code 870

NANPA records 5 assigned NXX blocks to rate center TUCKERMAN in area code 870, 0.6% of the 785 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 WINDSTREAM ARKANSAS, INC. (2), LEVEL 3 COMMUNICATIONS, LLC - AR (2), CSC VOICE, LLC (1). The earliest assignment on record here is 2004-08-11 and the most recent 2016-07-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
