Toll-free subscribers pay significant premiums so that others may contact them directly without having to pay for a long-distance call. Toll-free numbers begin with 800, 866, 877 or 888. Unfortunately, calls placed from such toll-free numbers often show up on caller ID devices without further identification. Fortunately, free databases provide information about such numbers, including ownership.
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.
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.
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.
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.
If you're having trouble finding information about a toll-free number, consider hiring a private investigator. To find a qualified investigator, contact your state professional private investigator association (PI Magazine lists all state associations. Under "PI Links" in the top blue bar at Pimagazine.com, select "State Associations-USA"). Request an investigator who specializes in phone number searches.
