WHEATON prefixes in area code 630

NANPA records 31 assigned NXX blocks to rate center WHEATON in area code 630, 4.0% of the 782 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. 8 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (17), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (3), PAETEC ITEL, LLC (3). The earliest assignment on record here is 2001-04-11 and the most recent 2005-03-02. 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 320, 331, 417, 785 – overlay codes cover the same geography, so a rate center is served by all of them.
