CRETE prefixes in area code 708

NANPA records 7 assigned NXX blocks to rate center CRETE in area code 708, 0.9% of the 784 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - IL (2), ILLINOIS BELL TEL CO (2), ONVOY, LLC (2). The earliest assignment on record here is 2005-12-21 and the most recent 2021-10-05. 6 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 402, 464, 531, 701 – overlay codes cover the same geography, so a rate center is served by all of them.
