BARTOW prefixes in area code 863

NANPA records 22 assigned NXX blocks to rate center BARTOW in area code 863, 4.7% 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. 13 holders hold those blocks, the largest being FRONTIER FLORIDA LLC DBA FRONTIER COMM OF FLORIDA (5), BANDWIDTH.COM CLEC, LLC - FL (3), ONVOY, LLC - FL (2). The earliest assignment on record here is 2001-11-01 and the most recent 2025-05-30. 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 code 478 – overlay codes cover the same geography, so a rate center is served by all of them.
