BARTONVL prefixes in area code 940

NANPA records 10 assigned NXX blocks to rate center BARTONVL in area code 940, 2.0% 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 FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (3), GRANDE COMMUNICATIONS NETWORKS, INC. - TX (3), LEVEL 3 COMMUNICATIONS, LLC - TX (1). The earliest assignment on record here is 2001-05-17 and the most recent 2023-12-21. 8 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
