SHEBOGNFLS prefixes in area code 920

NANPA records 6 assigned NXX blocks to rate center SHEBOGNFLS in area code 920, 0.8% 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. 4 holders hold those blocks, the largest being LEVEL 3 COMMUNICATIONS, LLC - WI (2), ONVOY, LLC - WI (2), WISCONSIN BELL INC (1). The earliest assignment on record here is 2005-05-03 and the most recent 2023-04-14. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
