ARMSTRONG prefixes in area code 712
NANPA records 3 assigned NXX blocks to rate center ARMSTRONG in area code 712, 0.5% of the 633 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. 2 holders hold those blocks, the largest being WINDSTREAM IOWA COMMUNICATIONS, INC. - NORTH (2), INDEPENDENT NETWORKS, LLC (1). The earliest assignment on record here is 2018-02-01 and the most recent 2018-02-01. 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 codes 217, 361, 447, 660 – overlay codes cover the same geography, so a rate center is served by all of them.
