FLORENCE prefixes in area code 601

NANPA records 3 assigned NXX blocks to rate center FLORENCE in area code 601, 0.4% 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. 2 holders hold those blocks, the largest being WINDSTREAM MISSISSIPPI, INC. (2), COMCAST IP PHONE, LLC (1). The earliest assignment on record here is 2005-07-25 and the most recent 2015-06-23. 2 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, 541 – overlay codes cover the same geography, so a rate center is served by all of them.
