MACKINAWCY prefixes in area code 231
NANPA records 5 assigned NXX blocks to rate center MACKINAWCY in area code 231, 0.9% of the 572 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. 5 holders hold those blocks, the largest being INTERACTIVE SERVICES NETWORK, INC. (1), AT&T ENTERPRISES, LLC (1), MICHIGAN BELL TEL CO (1). The earliest assignment on record here is 2002-08-27 and the most recent 2020-02-19. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
