PTWASHIGTN prefixes in area code 262

NANPA records 8 assigned NXX blocks to rate center PTWASHIGTN in area code 262, 1.3% 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. 7 holders hold those blocks, the largest being WISCONSIN BELL INC (2), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1), AT&T ENTERPRISES, LLC (1). The earliest assignment on record here is 2021-06-01 and the most recent 2021-06-01. 5 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
