PIPE CREEK prefixes in area code 830

NANPA records 4 assigned NXX blocks to rate center PIPE CREEK in area code 830, 0.8% 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. 3 holders hold those blocks, the largest being SOUTHWESTERN BELL (2), MATRIX TELECOM, LLC. S/I/I TNCI - TX (1), PEERLESS NETWORK OF TEXAS, LLC - TX (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
