DANDRIDGE prefixes in area code 865

NANPA records 5 assigned NXX blocks to rate center DANDRIDGE in area code 865, 1.0% of the 506 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 BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (2), AT&T ENTERPRISES, LLC (1), TON80 COMMUNICATIONS, LLC (1). The earliest assignment on record here is 2004-08-19 and the most recent 2022-01-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
