GRANTSPASS prefixes in area code 541

NANPA records 21 assigned NXX blocks to rate center GRANTSPASS in area code 541, 2.7% of the 783 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. 7 holders hold those blocks, the largest being QWEST CORPORATION (8), UNITED STATES CELLULAR - OR (4), NEW CINGULAR WIRELESS PCS, LLC (3). The earliest assignment on record here is 2001-03-22 and the most recent 2015-12-16. 14 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 code 458 – overlay codes cover the same geography, so a rate center is served by all of them.
