MULBERRY prefixes in area code 863

NANPA records 13 assigned NXX blocks to rate center MULBERRY in area code 863, 2.8% of the 472 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. 9 holders hold those blocks, the largest being FRONTIER FLORIDA LLC DBA FRONTIER COMM OF FLORIDA (3), METROPCS NETWORKS, LLC (2), PAETEC ITEL, LLC (2). The earliest assignment on record here is 2001-05-25 and the most recent 2023-08-16. 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 336, 479, 620, 743 – overlay codes cover the same geography, so a rate center is served by all of them.
