LOGANSPORT prefixes in area code 574

NANPA records 18 assigned NXX blocks to rate center LOGANSPORT in area code 574, 4.5% of the 403 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. 7 holders hold those blocks, the largest being FRONTIER NORTH, INC.. - IN (7), OMNIPOINT COMMUNICATIONS MIDWEST OPERATIONS, LLC (3), NEW CINGULAR WIRELESS PCS, LLC - IL (3). The earliest assignment on record here is 2001-07-02 and the most recent 2021-11-22. 15 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 270, 318 – overlay codes cover the same geography, so a rate center is served by all of them.
