KERRVILLE prefixes in area code 830

NANPA records 22 assigned NXX blocks to rate center KERRVILLE in area code 830, 4.4% 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. 8 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (7), WINDSTREAM COMMUNICATIONS KERRVILLE, L.P. (5), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - TX (3). The earliest assignment on record here is 2004-01-06 and the most recent 2024-03-20. 10 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
