LUCERNE prefixes in area code 574

NANPA records 3 assigned NXX blocks to rate center LUCERNE in area code 574, 0.7% of the 403 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. 3 holders hold those blocks, the largest being ONVOY, LLC - IN (1), TON80 COMMUNICATIONS, LLC (1), FRONTIER NORTH, INC.. - IN (1). The earliest assignment on record here is 2018-09-19 and the most recent 2022-01-13. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots. The same rate center name also appears in area code 660 – overlay codes cover the same geography, so a rate center is served by all of them.
