COTULLA prefixes in area code 830

NANPA records 5 assigned NXX blocks to rate center COTULLA in area code 830, 1.0% of the 496 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. 5 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (1), FRACTEL, LLC (1), LEVEL 3 COMMUNICATIONS, LLC - TX (1). The earliest assignment on record here is 2001-03-02 and the most recent 2020-06-23. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
