FLORENCE prefixes in area code 541

NANPA records 7 assigned NXX blocks to rate center FLORENCE in area code 541, 0.9% 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. 6 holders hold those blocks, the largest being QWEST CORPORATION (2), LEVEL 3 COMMUNICATIONS, LLC - OR (1), T-MOBILE USA, INC. (1). The earliest assignment on record here is 2001-06-18 and the most recent 2013-08-27. 6 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 254, 256, 458, 601 – overlay codes cover the same geography, so a rate center is served by all of them.
