CRYSTAL CY prefixes in area code 830

NANPA records 6 assigned NXX blocks to rate center CRYSTAL CY in area code 830, 1.2% 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. 4 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (3), PEERLESS NETWORK OF TEXAS, LLC - TX (1), SOUTHWESTERN BELL (1). The earliest assignment on record here is 2001-05-11 and the most recent 2005-02-17. 6 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
