MENOMONFLS prefixes in area code 262

NANPA records 19 assigned NXX blocks to rate center MENOMONFLS in area code 262, 3.0% of the 634 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. 9 holders hold those blocks, the largest being WISCONSIN BELL INC (10), PAETEC ITEL, LLC (2), LEVEL 3 TELECOM OF WISCONSIN, LP - WI (1). The earliest assignment on record here is 2001-07-03 and the most recent 2024-02-08. 13 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
