MEDFORD prefixes in area code 541

NANPA records 48 assigned NXX blocks to rate center MEDFORD in area code 541, 6.1% 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. 11 holders hold those blocks, the largest being QWEST CORPORATION (16), NEW CINGULAR WIRELESS PCS, LLC (7), UNITED STATES CELLULAR - OR (6). The earliest assignment on record here is 2001-10-23 and the most recent 2015-03-16. 29 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 339, 458, 580, 609 – overlay codes cover the same geography, so a rate center is served by all of them.
