STONE prefixes in area code 606

NANPA records 4 assigned NXX blocks to rate center STONE in area code 606, 0.6% 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. 4 holders hold those blocks, the largest being CSC WIRELESS, LLC (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), CSC VOICE, LLC (1). The earliest assignment on record here is 2019-03-28 and the most recent 2019-09-03. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
