DOWNERSGRV prefixes in area code 630
NANPA records 56 assigned NXX blocks to rate center DOWNERSGRV in area code 630, 7.2% 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. 12 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (29), MCIMETRO ACCESS TRANSMISSION SERVICES LLC - IL (5), LEVEL 3 COMMUNICATIONS, LLC - IL (4). The earliest assignment on record here is 2001-04-10 and the most recent 2026-07-21. 34 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 331 – overlay codes cover the same geography, so a rate center is served by all of them.
