BELVEDERE prefixes in area code 415
NANPA records 15 assigned NXX blocks to rate center BELVEDERE in area code 415, 1.9% 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. 7 holders hold those blocks, the largest being T-MOBILE USA, INC. (7), ONVOY, LLC - CA (2), PACIFIC BELL (2). The earliest assignment on record here is 2002-09-19 and the most recent 2015-08-03. 14 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.
