FLORENCE prefixes in area code 854

NANPA records 11 assigned NXX blocks to rate center FLORENCE in area code 854, 6.0% of the 182 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 TELNYX LLC (1), CSC WIRELESS, LLC (1), IP HORIZON LLC (1). The earliest assignment on record here is 2018-03-02 and the most recent 2026-01-08. 11 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.
