HARRISBURG prefixes in area code 618

NANPA records 9 assigned NXX blocks to rate center HARRISBURG in area code 618, 1.1% 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. 5 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (3), FRONTIER NORTH, INC. - IL (2), NEW CINGULAR WIRELESS PCS, LLC - IL (2). The earliest assignment on record here is 2002-05-13 and the most recent 2022-09-09. 7 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 327, 380, 458, 541 – overlay codes cover the same geography, so a rate center is served by all of them.
