LYLES prefixes in area code 931

NANPA records 5 assigned NXX blocks to rate center LYLES in area code 931, 0.9% 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - GA (1), TELEPORT COMMUNICATIONS AMERICA, LLC - TN (1), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1). The earliest assignment on record here is 2003-04-10 and the most recent 2021-11-17. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
