If you don't know about Google, you probably don't spend much time online. That's okay, as you don't have to be well versed in the Internet or search engines to use them to find a phone number when you miss someone from your past. Google can be a great tool, and it is easy to use as well. Try this first when you want more information to see if Google may be the only stop you need to make.
When logging on to Google, you can start with the easiest search. Put the name of your friend in the search box to see if you can find any results that are directly related to the person of which you are searching. Common names bring up a lot of results, so you may have to spend some time sifting through. Consider that you may be spelling the name wrong, or that a name has changed if nothing comes up. If that doesn't work, there are other things you can do.
Narrow down the results as best as you can if you are getting just too much to go through. You can get more precise hits on a name if you put a plus sign between the first and last name, or if you put the name in quotation marks. When you do those things, the results with the names together come up, but those that have the two names in different locations within the text will not. That helps greatly with time and accuracy.
If you still find that you are not getting very far, you can move on to something other than the general search tab. You may notice that you have options for things like news, maps, blogs, etc. Try those tabs to see if something comes up for your friend's name. You should try the ones that seem related to your search, but you never know what will come up with each one. It never hurts to try them all.
You may come up with a number, but you want to be sure of the owner before you call. That is understandable. If you want a way to get some confirmation on the currency or the relevance of a number, go to a site that can show you who owns a number .
