How to Block Fax Calls

The FCC rules prohibit unsolicited fax advertisements (under most circumstances). In general, to stop unwanted fax advertisements, you must make an “opt-out” request which must:

• identify the fax number or numbers to which it relates; and
• be sent to the telephone number, fax number, Web site address, or e-mail address identified on the fax advertisement.

If you change your mind about receiving fax advertisements, you can subsequently grant express permission to receive faxes from a particular sender, orally or in writing.

This won't necessarily stop the faxes - especially if they are scammers deliberately violating the law, but it does give you the right to sue them.  So, if that didn't work, what's next?

Try to Identify the Sender

1. Try a Google search of any of the phone numbers on the fax, such as the sending number (if it is present), the respond-to number or removal-me number.
2. Check whether the FCC has already received complaints about the fax: 
   Click here to visit Telecommunications Consumers Division - Unsolicited Faxes and search for the title of the fax in the search box on that page.
3. See if this Junk Fax website has identified the fax:
   click here to search the Junk Fax Index. 
4. Trap  the call - After you receive a junk fax, immediately dial *57. Note the date and time on the fax. You can call the police to report harassing phone calls or call the phone company to do the same and require them to start monitoring your line for more calls. Once the phone company tells you the number,  you have to find the owner of the number.  See this website for more information.
5. Call the Remove-me number and match the response against the table below.
