HONOR prefixes in area code 231

NANPA records 4 assigned NXX blocks to rate center HONOR in area code 231, 0.7% 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. 4 holders hold those blocks, the largest being INTERACTIVE SERVICES NETWORK, INC. (1), CHARTER IP ENABLED SERVICES, LLC (1), BRIGHTSPEED OF MICHIGAN, LLC (1). The earliest assignment on record here is 2004-03-24 and the most recent 2021-01-08. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
