TIGERTON prefixes in area code 715

NANPA records 3 assigned NXX blocks to rate center TIGERTON in area code 715, 0.4% of the 785 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 NEW CINGULAR WIRELESS PCS, LLC - IL (1), FRONTIER COMMUNICATIONS OF WISCONSIN LLC (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2004-08-13 and the most recent 2025-01-27. 3 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
