POINTREYES prefixes in area code 415

NANPA records 8 assigned NXX blocks to rate center POINTREYES in area code 415, 1.0% 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. 6 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (3), NORTH COUNTY COMMUNICATION CORPORATION - CA (1), PACIFIC BELL (1). The earliest assignment on record here is 2015-06-09 and the most recent 2015-06-09. 7 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 628 – overlay codes cover the same geography, so a rate center is served by all of them.
