TOOELE prefixes in area code 435

NANPA records 30 assigned NXX blocks to rate center TOOELE in area code 435, 6.0% of the 501 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. 17 holders hold those blocks, the largest being QWEST CORPORATION (5), T-MOBILE USA, INC. (4), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-02-02 and the most recent 2023-08-09. 23 of them are in thousands-block pooling, so those prefixes are shared between carriers in 1,000-number lots.
