CENTRAL LK prefixes in area code 231
NANPA records 4 assigned NXX blocks to rate center CENTRAL LK 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), FRONTIER NORTH, INC. - MI (1), 123.NET, LLC (1). The earliest assignment on record here is 2002-08-12 and the most recent 2015-08-24. 2 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
