DFUNIAKSPG prefixes in area code 850

NANPA records 10 assigned NXX blocks to rate center DFUNIAKSPG in area code 850, 1.3% 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. 8 holders hold those blocks, the largest being CENTURYLINK OF FLORIDA, INC. (CENTRAL) (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - FL (1), SOUTHERN COMMUNICATIONS SERVICES, INC. (1). The earliest assignment on record here is 2001-03-22 and the most recent 2018-04-25. 9 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 code 448 – overlay codes cover the same geography, so a rate center is served by all of them.
