CHILLICOTH prefixes in area code 660

NANPA records 9 assigned NXX blocks to rate center CHILLICOTH in area code 660, 1.7% of the 518 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (3), NEW CINGULAR WIRELESS PCS, LLC - IL (2), LEVEL 3 COMMUNICATIONS, LLC - MO (1). The earliest assignment on record here is 2001-05-10 and the most recent 2019-08-01. 8 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, 309, 641, 740 – overlay codes cover the same geography, so a rate center is served by all of them.
