LK PRESTON prefixes in area code 605

NANPA records 5 assigned NXX blocks to rate center LK PRESTON in area code 605, 0.7% of the 745 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), VALLEY COMMUNICATIONS, INC. D/B/A VALLEY FIBERCOM (1), ONVOY, LLC - SD (1). The earliest assignment on record here is 2002-09-23 and the most recent 2019-08-26. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
