DEANVILLE prefixes in area code 979

NANPA records 4 assigned NXX blocks to rate center DEANVILLE in area code 979, 1.0% of the 413 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), ONVOY, LLC - TX (1), TEXAS COMMUNICATIONS, INC. (1). The earliest assignment on record here is 2004-03-09 and the most recent 2023-06-22. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
