OSHKOSH prefixes in area code 920
NANPA records 40 assigned NXX blocks to rate center OSHKOSH in area code 920, 5.1% 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. 18 holders hold those blocks, the largest being WISCONSIN BELL INC (12), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (7), T-MOBILE USA, INC. (2). The earliest assignment on record here is 2001-02-05 and the most recent 2023-01-13. 25 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 308 – overlay codes cover the same geography, so a rate center is served by all of them.
