OKLD MN-PD prefixes in area code 510
NANPA records 204 assigned NXX blocks to rate center OKLD MN-PD in area code 510, 26.0% of the 785 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. 20 holders hold those blocks, the largest being PACIFIC BELL (64), NEW CINGULAR WIRELESS PCS, LLC (39), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (28). The earliest assignment on record here is 2001-08-22 and the most recent 2021-11-18. 100 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 341 – overlay codes cover the same geography, so a rate center is served by all of them.
