WARTRACE prefixes in area code 931

NANPA records 3 assigned NXX blocks to rate center WARTRACE in area code 931, 0.6% of the 538 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. 3 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2004-10-26 and the most recent 2023-05-15. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
