HINSDALE prefixes in area code 630

NANPA records 75 assigned NXX blocks to rate center HINSDALE in area code 630, 9.6% 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. 10 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (33), NEW CINGULAR WIRELESS PCS, LLC - IL (15), LEVEL 3 COMMUNICATIONS, LLC - IL (8). The earliest assignment on record here is 2001-04-11 and the most recent 2010-06-28. 40 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 312, 331, 406, 413 – overlay codes cover the same geography, so a rate center is served by all of them.
