DE KALB prefixes in area code 815
NANPA records 24 assigned NXX blocks to rate center DE KALB in area code 815, 3.1% of the 786 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. 11 holders hold those blocks, the largest being FRONTIER NORTH, INC. - IL (7), UNITED STATES CELLULAR - IL (4), T-MOBILE USA, INC. (3). The earliest assignment on record here is 2001-05-22 and the most recent 2009-06-10. 15 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 601, 769, 779, 816 – overlay codes cover the same geography, so a rate center is served by all of them.
