SCHULENBG prefixes in area code 979

NANPA records 4 assigned NXX blocks to rate center SCHULENBG 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 TEXAS COMMUNICATIONS, INC. (1), FRACTEL, LLC (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2004-06-03 and the most recent 2019-09-20. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
