MUSKEGO prefixes in area code 262

NANPA records 5 assigned NXX blocks to rate center MUSKEGO in area code 262, 0.8% 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. 4 holders hold those blocks, the largest being WISCONSIN BELL INC (2), LEVEL 3 COMMUNICATIONS, LLC - WI (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
