ROCKFORD prefixes in area code 779
NANPA records 44 assigned NXX blocks to rate center ROCKFORD in area code 779, 12.4% of the 354 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. 31 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - IL (5), ONVOY, LLC (5), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2007-03-27 and the most recent 2026-10-06. 44 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 256, 419, 509, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
