FRNK OLIVR prefixes in area code 510
NANPA records 45 assigned NXX blocks to rate center FRNK OLIVR in area code 510, 5.7% 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. 12 holders hold those blocks, the largest being PACIFIC BELL (25), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (5), SPOK, INC. (2). The earliest assignment on record here is 2001-03-01 and the most recent 2019-02-06. 30 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.
