Whitepages.com provides a reverse phone number lookup feature for 800 numbers in addition to most other landline numbers. Other websites, such as WhoCallsMe.com, provide listings of user-submitted numbers along with user comments about each number.
To find the information about an 800 number, click on the Phone tab at the top of Whitepages.com. Enter the number in the search bar, and press the Enter key.
If no information is returned on Whitepages.com, the phone number may be Canadian, since Canadian phone numbers share the +1 country code. Canada411.ca provides listings of Canadian numbers. Enter the number in the Reverse Phone Number Lookup section on the main page, and press Enter for information.
If no information can be found on Whitepages.com or Canada411.ca, user-submitted sites such as WhoCallsMe.com may list an 800 number. WhoCallsMe.com lets anyone submit numbers to the site and add comments about them. The site is often used by people to post numbers related to scams and harassment. Be cautious, however, because user-submitted information is not always accurate.
Add your phone number to the National Do Not Call Registry at DoNotCall.gov to stop unsolicited phone calls from American companies. However, criminals and non-American companies often ignore this list.
