SNJS NORTH prefixes in area code 408
NANPA records 139 assigned NXX blocks to rate center SNJS NORTH in area code 408, 17.7% of the 787 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. 15 holders hold those blocks, the largest being PACIFIC BELL (72), CELLCO PARTNERSHIP DBA VERIZON WIRELESS - CA (12), MCIMETRO ACCESS TRANSMISSION SERVICES LLC (9). The earliest assignment on record here is 2001-03-08 and the most recent 2012-12-26. 78 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 669 – overlay codes cover the same geography, so a rate center is served by all of them.
