ALPHA prefixes in area code 309
NANPA records 3 assigned NXX blocks to rate center ALPHA in area code 309, 0.4% 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. 3 holders hold those blocks, the largest being CITIZENS TELECOM CO ILLINOIS-FRONTIER CITIZENS -IL (1), WOODHULL COMMUNITY TEL. CO. (1), ONVOY, LLC (1). The earliest assignment on record here is 2023-06-26 and the most recent 2023-06-26. 2 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 code 563 – overlay codes cover the same geography, so a rate center is served by all of them.
