AURORA prefixes in area code 630

NANPA records 55 assigned NXX blocks to rate center AURORA in area code 630, 7.0% 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. 12 holders hold those blocks, the largest being ILLINOIS BELL TEL CO (21), T-MOBILE USA, INC. (11), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (5). The earliest assignment on record here is 2001-04-11 and the most recent 2021-01-25. 35 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 207, 218, 234, 252 – overlay codes cover the same geography, so a rate center is served by all of them.
