SO PLACER prefixes in area code 916
NANPA records 25 assigned NXX blocks to rate center SO PLACER in area code 916, 3.2% 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. 10 holders hold those blocks, the largest being PACIFIC BELL (10), NEW CINGULAR WIRELESS PCS, LLC (3), ONVOY, LLC - CA (2). The earliest assignment on record here is 2002-03-22 and the most recent 2021-12-17. 19 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 279 – overlay codes cover the same geography, so a rate center is served by all of them.
