WINCHESTER prefixes in area code 931

NANPA records 15 assigned NXX blocks to rate center WINCHESTER in area code 931, 2.8% 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. 9 holders hold those blocks, the largest being POWERTEL NASHVILLE LICENSES, INC. (3), LEVEL 3 COMMUNICATIONS, LLC - TN (3), BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (3). The earliest assignment on record here is 2002-05-02 and the most recent 2022-03-01. 12 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 217, 447, 540, 603 – overlay codes cover the same geography, so a rate center is served by all of them.
