HIGH HILL prefixes in area code 979
NANPA records 3 assigned NXX blocks to rate center HIGH HILL in area code 979, 0.7% of the 413 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 TEXAS COMMUNICATIONS, INC. (1), NEW CINGULAR WIRELESS PCS, LLC - IL (1), COLORADO VALLEY TEL. COOP., INC. (1). The earliest assignment on record here is 2004-06-03 and the most recent 2013-09-18. 2 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 code 636 – overlay codes cover the same geography, so a rate center is served by all of them.
