WALWORTH prefixes in area code 262

NANPA records 3 assigned NXX blocks to rate center WALWORTH in area code 262, 0.5% 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. 3 holders hold those blocks, the largest being FRONTIER NORTH INC. - WI (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1), FRACTEL, LLC (1). The earliest assignment on record here is 2020-02-19 and the most recent 2020-02-19. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
