TAMPASTH prefixes in area code 813

NANPA records 33 assigned NXX blocks to rate center TAMPASTH in area code 813, 4.2% of the 782 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. 14 holders hold those blocks, the largest being FRONTIER FLORIDA LLC DBA FRONTIER COMM OF FLORIDA (6), NEW CINGULAR WIRELESS PCS, LLC - GA (5), BANDWIDTH.COM CLEC, LLC - FL (4). The earliest assignment on record here is 2002-01-03 and the most recent 2023-10-18. 30 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 656 – overlay codes cover the same geography, so a rate center is served by all of them.
