707 is a North American area code that benefits certain parts of the state of California. As such, it covers a total of fourteen counties, some of which are Yolo, Sonoma, Napa and Mendocino.
Area code 707 also contains one hundred thirty-seven cities or towns that are within these fourteen counties. Some of these are as follows.
This area code has well over six hundred total extensions and the population within these counties and cities is is about one point three million people, with white making up almost all of that number, then followed by Hispanics, then followed up by Asians and finally blacks, leaving the female and male population ratios to be pretty much exact.
This area code was created as a split from 405 in nineteen fifty-nine (1959). Amazingly enough though, the area in which it serves has not once changed in all of those decades, which makes this the longest serving non effected area code in the entire state of California, which is pretty remarkable considering all of the populous growth changes that the state frequently goes through.
If you are curious about what portion of the state is served by this area code, to answer the question it is the very top, north western portion of the state, or the very left hand corner of California.
