CALUMET CY prefixes in area code 708
NANPA records 13 assigned NXX blocks to rate center CALUMET CY in area code 708, 1.7% 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. 6 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (5), LEVEL 3 COMMUNICATIONS, LLC - IL (3), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-04-12 and the most recent 2016-02-29. 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 code 464 – overlay codes cover the same geography, so a rate center is served by all of them.
