WAUPACA prefixes in area code 534

NANPA records 4 assigned NXX blocks to rate center WAUPACA in area code 534, 4.1% of the 98 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. 4 holders hold those blocks, the largest being TON80 COMMUNICATIONS, LLC (1), ONVOY, LLC - WI (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1). The earliest assignment on record here is 2015-07-24 and the most recent 2021-04-08. 4 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 715 – overlay codes cover the same geography, so a rate center is served by all of them.
