SOMERSET prefixes in area code 830

NANPA records 4 assigned NXX blocks to rate center SOMERSET 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), TWC IP ENABLED SERVICES, LLC (1), PEERLESS NETWORK OF TEXAS, LLC - TX (1). The earliest assignment on record here is 2003-02-13 and the most recent 2003-02-13. 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area codes 220, 534, 582, 606 – overlay codes cover the same geography, so a rate center is served by all of them.
