Significance of 650 Area Code

I don’t know if you notice that there is a three-digit number that precedes a telephone number any time you receive a call from your cell phone. Any time you see the three-digit code 650, it suggests that the call comes from any of the cities or counties listed above. However, there may be an exemption to this. With the use of mobile phone or roaming phone feature, the caller may not necessarily be at any of these cities or counties at the time of calling.

Nevertheless, knowing the counties and cities that the 650 area code covers can guide you when to call a particular person. This is because the person you want to call may be in a time zone that is different from your own.
