SUMMERTOWN prefixes in area code 931

NANPA records 4 assigned NXX blocks to rate center SUMMERTOWN in area code 931, 0.7% 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - TN (1), NEW CINGULAR WIRELESS PCS, LLC - GA (1), FRACTEL, LLC (1). The earliest assignment on record here is 2001-03-07 and the most recent 2020-07-15. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
