NANPA records 5 assigned NXX blocks to rate center DILLEY in area code 830, 1.0% 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 FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), TELNYX LLC (1), PEERLESS NETWORK OF TEXAS, LLC - TX (1). The earliest assignment on record here is 2001-05-14 and the most recent 2007-06-12. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
