FREDECKSBG prefixes in area code 830

NANPA records 14 assigned NXX blocks to rate center FREDECKSBG in area code 830, 2.8% 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (4), FRONTIER SOUTHWEST INC DBA FRONTIER COMM OF TEXAS (3), SPOK, INC. (1). The earliest assignment on record here is 2003-06-19 and the most recent 2023-09-29. 8 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 234, 330, 540, 563 – overlay codes cover the same geography, so a rate center is served by all of them.
