BIG WELLS prefixes in area code 830

NANPA records 3 assigned NXX blocks to rate center BIG WELLS in area code 830, 0.6% 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. 3 holders hold those blocks, the largest being PEERLESS NETWORK OF TEXAS, LLC - TX (1), SOUTHWESTERN BELL (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2003-11-05 and the most recent 2021-05-27. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
