MERTON prefixes in area code 262

NANPA records 4 assigned NXX blocks to rate center MERTON in area code 262, 0.6% 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 TELEPORT COMMUNICATIONS AMERICA, LLC WI (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1), WISCONSIN BELL INC (1). 4 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
