COAL CITY prefixes in area code 815
NANPA records 5 assigned NXX blocks to rate center COAL CITY in area code 815, 0.6% 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. 5 holders hold those blocks, the largest being CENTURYLINK COMMUNICATIONS, LLC (1), FIRST COMMUNICATIONS, LLC (1), ILLINOIS BELL TEL CO (1). The earliest assignment on record here is 2001-10-23 and the most recent 2019-02-18. 5 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 779 – overlay codes cover the same geography, so a rate center is served by all of them.
