UVALDE prefixes in area code 830

NANPA records 14 assigned NXX blocks to rate center UVALDE in area code 830, 2.8% 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. 8 holders hold those blocks, the largest being SOUTHWESTERN BELL (4), NEW CINGULAR WIRELESS PCS, LLC - IL (3), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-04-05 and the most recent 2023-12-21. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
