OCONOMOWOC prefixes in area code 262
NANPA records 19 assigned NXX blocks to rate center OCONOMOWOC 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. 11 holders hold those blocks, the largest being WISCONSIN BELL INC (4), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (3), ONVOY, LLC - WI (2). The earliest assignment on record here is 2002-01-15 and the most recent 2024-03-27. 14 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
