BANDERA prefixes in area code 830

NANPA records 7 assigned NXX blocks to rate center BANDERA in area code 830, 1.4% 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. 6 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1), ONVOY SPECTRUM, LLC (1). The earliest assignment on record here is 2002-02-05 and the most recent 2021-05-27. 7 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
