There are many ways to search for and learn more about any phone number, but you may not have to do as much as you think. You may only need to get a general idea of where a number came from to determine if you know the person or if you want to answer the phone the next time that number calls. You can see what you can find out through the area code of any number. When you receive a call from the 650 area code, you can learn something about the caller.
One of the first things you’ll learn about the 650 area code is that it covers only a small geographic area in north central California. This area is just outside of the San Francisco area. It is a coastal area of the state, and that should tell you that it is a highly populated area. There are two counties involved with the area code and those are San Mateo and Santa Clara County.
Now you have a general area, but you can get more information from the rest of the phone number. The area code is the first three digits of a ten-digit number. Then you want to look at the next three numbers that are called the prefix. Those may tell you the name of a smaller city, or are in use in a more urban area. You have to search for the prefix within the 650 area code, as prefixes are reused in each area code.
You’ll find that the call can come from anywhere in the area code, obviously, but there are some larger areas that are the most likely sources. These would include the cities of Palo Alto and other areas such as Menlo Park, Brisbane, Atherton, Redwood City, and South San Francisco.
Although there are many places and sources you can use to find out about calls from the 650 area code, you can find everything you need in a few places. There are great websites that can help you when you need to know more about a phone number, but a name may not be necessary.
