OKLD MN-PD prefixes in area code 341

NANPA records 8 assigned NXX blocks to rate center OKLD MN-PD in area code 341, 7.1% 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. 6 holders hold those blocks, the largest being TELEPORT COMMUNICATIONS AMERICA, LLC - CA (2), ONVOY, LLC - CA (2), BANDWIDTH.COM CLEC, LLC - CA (1). The earliest assignment on record here is 2021-07-07 and the most recent 2025-10-02. 8 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.
