PIONEER prefixes in area code 419

NANPA records 3 assigned NXX blocks to rate center PIONEER in area code 419, 0.4% of the 783 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. 2 holders hold those blocks, the largest being FRONTIER NORTH, INC. - OH (2), NEW CINGULAR WIRELESS PCS, LLC - IL (1). The earliest assignment on record here is 2001-04-26 and the most recent 2001-04-26. 3 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 209, 567 – overlay codes cover the same geography, so a rate center is served by all of them.
