CRYSTAL LK prefixes in area code 815
NANPA records 16 assigned NXX blocks to rate center CRYSTAL LK in area code 815, 2.0% 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. 7 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (7), METROPCS, INC. (2), TELEPORT COMMUNICATIONS AMERICA, LLC - IL (2). The earliest assignment on record here is 2001-03-22 and the most recent 2006-06-06. 9 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 641, 779 – overlay codes cover the same geography, so a rate center is served by all of them.
