FREDERCKTN prefixes in area code 573

NANPA records 6 assigned NXX blocks to rate center FREDERCKTN in area code 573, 0.8% 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. 4 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - MO (3), LEVEL 3 COMMUNICATIONS, LLC - MO (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2001-05-01 and the most recent 2006-09-29. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 220, 235, 724, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
