Free furniture along side the road may not be the free things that you want. Most won't take such items, and prefer to know that they are sitting on something new, or something that has come from someone with whom they are familiar. That makes sense, and is probably the best way to think about those things. However, when it comes to information, you may want to see what you can get for free before you pay.
If you want to find out more about a phone number, free is the way to go at first. You can always go in a different direction if you can not find what you want through various free tools and sources of information. As with anything else online, you do have to be careful where you get your information. Some sources are not accurate, though when it comes to phone numbers, you can usually go with what you have found.
When a number is completely alien to you, you have two options. One would be to treat that number as if it were a landline, and the other would be to see if the number belongs to someone with a cell phone. Think about landlines first, as they are the easiest to trace. Go to the online residential phone listings (aka the white pages) and use the reverse search. If nothing comes up, the number is unlisted or cellular.
Use search tools like Google, MSN, or other search engines next. See what happens if you search the number. You can also find people finders like Yahoo People to see if they can do a reverse number search for you. You may also find some luck searching through social networks, and the professional networks that people use to make business connections. These have worked in locating many numbers in the past.
Lastly, you can find a free cell phone search that can tell you a bit about almost any phone number. The free version can verify if a number is mobile or not. If so, it can tell you where the contract was bought and through which company. There are also going to be links that go to a paid service that can tell you so much more if you want that type of information.
