FOSTORIA prefixes in area code 419

NANPA records 6 assigned NXX blocks to rate center FOSTORIA in area code 419, 0.8% 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. 3 holders hold those blocks, the largest being CELLCO PARTNERSHIP DBA VERIZON WIRELESS - OH (3), OHIO BELL TEL CO (2), PEERLESS NETWORK OF OHIO, LLC - OH (1). The earliest assignment on record here is 2001-07-23 and the most recent 2019-10-03. 4 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, 989 – overlay codes cover the same geography, so a rate center is served by all of them.
