GAINESBORO prefixes in area code 931

NANPA records 5 assigned NXX blocks to rate center GAINESBORO 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. 2 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TN (3), TWIN LAKES TEL. COOP. CORP. (2). The earliest assignment on record here is 2005-10-19 and the most recent 2014-02-26. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 540, 826 – overlay codes cover the same geography, so a rate center is served by all of them.
