MICHIE prefixes in area code 731

NANPA records 4 assigned NXX blocks to rate center MICHIE in area code 731, 1.0% of the 395 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. 4 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (1), LEVEL 3 COMMUNICATIONS, LLC - TN (1), FRACTEL, LLC (1). The earliest assignment on record here is 2002-04-25 and the most recent 2021-09-08. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
