OKLD FRTVL prefixes in area code 341

NANPA records 10 assigned NXX blocks to rate center OKLD FRTVL in area code 341, 8.8% 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. 5 holders hold those blocks, the largest being FRACTEL, LLC (5), ONVOY, LLC - CA (2), COMCAST PHONE OF CALIFORNIA, LLC (1). The earliest assignment on record here is 2019-12-03 and the most recent 2024-09-12. 10 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.
