WILLIAMSBG prefixes in area code 606

NANPA records 8 assigned NXX blocks to rate center WILLIAMSBG in area code 606, 1.3% of the 639 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 POWERTEL KENTUCKY LICENSES, INC. (2), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - KY (2), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2). The earliest assignment on record here is 2012-02-27 and the most recent 2020-08-19. 6 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 231, 283, 319, 413 – overlay codes cover the same geography, so a rate center is served by all of them.
