JACKSBORO prefixes in area code 940

NANPA records 7 assigned NXX blocks to rate center JACKSBORO in area code 940, 1.4% of the 506 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. 6 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (2), WEB FIRE COMMUNICATIONS, INC. - TX (1), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2003-03-26 and the most recent 2025-01-29. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
