CROCKER prefixes in area code 573

NANPA records 4 assigned NXX blocks to rate center CROCKER in area code 573, 0.5% of the 786 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 MISSOURI, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (1), LEVEL 3 COMMUNICATIONS, LLC - MO (1). The earliest assignment on record here is 2004-03-10 and the most recent 2015-06-17. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
