LOMIRA prefixes in area code 920

NANPA records 3 assigned NXX blocks to rate center LOMIRA in area code 920, 0.4% of the 785 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. 2 holders hold those blocks, the largest being T-MOBILE USA, INC. (2), FRONTIER NORTH INC. - WI (1). The earliest assignment on record here is 2001-04-18 and the most recent 2021-08-04. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
