ROSELLE prefixes in area code 708

NANPA records 41 assigned NXX blocks to rate center ROSELLE in area code 708, 5.2% of the 784 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. 1 holder holds those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (41). 31 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 224, 312, 331, 630 – overlay codes cover the same geography, so a rate center is served by all of them.
