SUTHELDSPG prefixes in area code 830
NANPA records 4 assigned NXX blocks to rate center SUTHELDSPG 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 FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (2), PEERLESS NETWORK OF TEXAS, LLC - TX (1), TWC IP ENABLED SERVICES, LLC (1). The earliest assignment on record here is 2003-11-04 and the most recent 2026-07-22. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
