NORTHRUP prefixes in area code 979

NANPA records 3 assigned NXX blocks to rate center NORTHRUP in area code 979, 0.7% 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. 3 holders hold those blocks, the largest being TEXAS COMMUNICATIONS, INC. (1), FRACTEL, LLC (1), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (1). The earliest assignment on record here is 2004-06-03 and the most recent 2021-03-02. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
