How to Find Out Who a Toll

1. Review your voice mail or answering machine for messages accompanying the call from the number in question. Many toll-free subscribers leave messages identifying themselves and explaining the reasons for their calls.
2. Conduct a reverse number search. Enter the number as it appears on your caller ID in the search field of your preferred Internet search engine.
3. Look up the number in a toll-free directory. One such directory is the National Tollfree Directory, which contains advertising listings of business toll-free numbers submitted by businesses (which means not all toll-free numbers are listed). Go to Internettollfree.com/800-number-reverse-lookup.html. In the center of the page, in the 'Find a Business' box, enter the phone number, press the 'Search' button, and review the results. If the toll-free number is in the database, information about it will be displayed.
4. Research the number in a user database. 800notes.com is a user database of phone numbers, including toll-free numbers, which provides user-supplied information such as the content of calls received, who owns numbers, frequency of received calls and more. Enter the toll-free phone number in the box toward the top of the web page, press the 'Search' button, and review the results.
