SANDUSKY prefixes in area code 419

NANPA records 24 assigned NXX blocks to rate center SANDUSKY in area code 419, 3.1% 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. 9 holders hold those blocks, the largest being OHIO BELL TEL CO (6), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (4), NEW CINGULAR WIRELESS PCS, LLC - IL (4). The earliest assignment on record here is 2001-05-08 and the most recent 2002-04-19. 13 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 567, 810 – overlay codes cover the same geography, so a rate center is served by all of them.
