OLNEY prefixes in area code 618
NANPA records 16 assigned NXX blocks to rate center OLNEY in area code 618, 2.0% of the 786 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. 9 holders hold those blocks, the largest being NEW CINGULAR WIRELESS PCS, LLC - IL (5), FRONTIER NORTH, INC. - IL (3), ONVOY SPECTRUM, LLC (2). The earliest assignment on record here is 2001-12-06 and the most recent 2023-07-31. 13 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 406, 573, 730, 940 – overlay codes cover the same geography, so a rate center is served by all of them.
