FLORENCE prefixes in area code 256

NANPA records 29 assigned NXX blocks to rate center FLORENCE in area code 256, 3.7% of the 786 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. 10 holders hold those blocks, the largest being BELLSOUTH TELECOMM INC DBA SOUTH CENTRAL BELL TEL (9), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - AL (7), POWERTEL BIRMINGHAM LICENSES, INC. (4). The earliest assignment on record here is 2001-04-11 and the most recent 2021-08-10. 19 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, 458, 541, 601 – overlay codes cover the same geography, so a rate center is served by all of them.
