NEWBURG prefixes in area code 262

NANPA records 11 assigned NXX blocks to rate center NEWBURG in area code 262, 1.7% 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 CELLCO PARTNERSHIP DBA VERIZON WIRELESS - WI (2), UNITED STATES CELLULAR - WI (2), ONVOY, LLC - WI (1). The earliest assignment on record here is 2001-06-05 and the most recent 2023-01-09. 10 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 codes 223, 304, 325, 573 – overlay codes cover the same geography, so a rate center is served by all of them.
