SULLIVAN prefixes in area code 262

NANPA records 3 assigned NXX blocks to rate center SULLIVAN 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. 2 holders hold those blocks, the largest being BRIGHTSPEED OF WESTERN WISCONSIN, LLC (2), TELEPORT COMMUNICATIONS AMERICA, LLC WI (1). The earliest assignment on record here is 2001-06-18 and the most recent 2002-05-14. 2 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 207, 217, 419, 447 – overlay codes cover the same geography, so a rate center is served by all of them.
