FRNK MAIN prefixes in area code 341

NANPA records 16 assigned NXX blocks to rate center FRNK MAIN in area code 341, 14.2% of the 113 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 FRACTEL, LLC (6), ONVOY, LLC - CA (3), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (2). The earliest assignment on record here is 2019-06-07 and the most recent 2026-08-07. 16 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 510 – overlay codes cover the same geography, so a rate center is served by all of them.
