ARMADA prefixes in area code 586
NANPA records 12 assigned NXX blocks to rate center ARMADA in area code 586, 2.2% of the 546 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. 8 holders hold those blocks, the largest being OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (4), NEW CINGULAR WIRELESS PCS, LLC - IL (2), ONVOY, LLCV - MI (1). The earliest assignment on record here is 2002-08-23 and the most recent 2026-05-29. 12 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
