NORTHPEKIN prefixes in area code 309

NANPA records 4 assigned NXX blocks to rate center NORTHPEKIN in area code 309, 0.5% 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. 4 holders hold those blocks, the largest being ONVOY, LLC (1), BANDWIDTH.COM CLEC, LLC - IL (1), BRIGHTSPEED OF ILLINOIS, LLC (1). The earliest assignment on record here is 2008-05-15 and the most recent 2021-06-24. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
