How to Get Info About a Phone Number Free

1. Use a reverse search service to see if name and address information is available about the telephone number through a free online directory. There are many to choose from, and one is listed in the Resources section. This is the easiest way to get free information about a phone number unless it is unlisted.
2. Visit a phone call tracking website to see if others have reported receiving calls from the same number. If the number is a business, others may have reported getting calls in an online database such as 800notes.com or whocallsme.com (see Resources). Sometimes the only information will be that the number is known for making hang-up or harassing calls. Often, however, other visitors to the site will have additional information on the caller's name, company and address.
3. Narrow down the area code and prefix. If you cannot find information on the exact telephone number, you can often pinpoint its place of origin by doing some research on the area code and the first 3 digits of the number. There are many online sources for looking up area codes, one of which is listed in the Resources. To find the location of a prefix, search the area code and prefix together in Google (for example, for phone number (312) 555-1234, you would search 312 555). You will see a list of individual and business results, including addresses, which will tell you the number's probable location.
4. Call the number and ask for the information directly from the person who answers. This direct approach is especially good if you have a solid reason for wanting to know, such as receiving harassing calls or hang-ups from the number in question. Even if the person at the other end refuses to give out the information, he will be on notice that you are gathering information and may stop calling you. If the number you're investigating is a business number, you may not even need to ask because the person at the other end will probably answer with the business name.
