HARBSNALPN prefixes in area code 619

NANPA records 10 assigned NXX blocks to rate center HARBSNALPN in area code 619, 1.3% 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. 5 holders hold those blocks, the largest being BANDWIDTH.COM CLEC, LLC - CA (3), ONVOY, LLC - CA (2), PACIFIC BELL (2). The earliest assignment on record here is 2014-06-13 and the most recent 2021-03-01. 9 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 858 – overlay codes cover the same geography, so a rate center is served by all of them.
