TWIN LAKES prefixes in area code 262

NANPA records 3 assigned NXX blocks to rate center TWIN LAKES 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 LEVEL 3 COMMUNICATIONS, LLC - WI (1), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1), FRONTIER NORTH INC. - WI (1). The earliest assignment on record here is 2002-08-20 and the most recent 2002-08-20. 3 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 codes 505, 507 – overlay codes cover the same geography, so a rate center is served by all of them.
