SNFC JUNPR prefixes in area code 650

NANPA records 22 assigned NXX blocks to rate center SNFC JUNPR in area code 650, 3.1% of the 717 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. 8 holders hold those blocks, the largest being PACIFIC BELL (15), METROPCS, INC. (1), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (1). The earliest assignment on record here is 2001-08-22 and the most recent 2023-04-07. 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 codes 415, 628 – overlay codes cover the same geography, so a rate center is served by all of them.
