AGUA DULCE prefixes in area code 361

NANPA records 3 assigned NXX blocks to rate center AGUA DULCE in area code 361, 0.6% of the 538 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 FRACTEL, LLC (1), VTX COMMUNICATIONS, LLC (1), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (1). The earliest assignment on record here is 2011-08-18 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.
