IRON CITY prefixes in area code 229

NANPA records 3 assigned NXX blocks to rate center IRON CITY in area code 229, 0.4% of the 685 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 ONVOY, LLC - GA (1), COMMIO, LLC (1), GEORGIA WINDSTREAM, INC. (1). The earliest assignment on record here is 2023-08-17 and the most recent 2023-08-17. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
