NEENAH prefixes in area code 920

NANPA records 20 assigned NXX blocks to rate center NEENAH in area code 920, 2.5% 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. 9 holders hold those blocks, the largest being WISCONSIN BELL INC (9), ONVOY, LLC - WI (2), LEVEL 3 COMMUNICATIONS, LLC - WI (2). The earliest assignment on record here is 2003-02-05 and the most recent 2023-12-19. 12 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 274 – overlay codes cover the same geography, so a rate center is served by all of them.
