In 1999, a three-way, two-phase split of area code 707 was scheduled by Pacific Bell such that a new area code (627) would have served most of Napa and Sonoma Counties and small portions of Marin and Mendocino Counties, while another new area code (369) would have served Solano County as well as a small portion of Napa County, beginning in December 2000 and October 2001, respectively.
