Find out who is calling and why: Debt collectors, telemarketers, charities, and survey companies often call without leaving a message. Lookup the number to read the reports of other users.
Report telemarketing calls: Make the Do Not Call list offenders notice the problem by reporting their practices. No business wants bad publicity.
Report phone fraud: Did someone try to scam you? Reporting the number is the fastest way to make public aware, and prevent others from falling victim to the scam.
Check out a business: Read other users' feedback about the phone number owner.
You can also report calls you have received if the number is not listed on the site if a look-up of the number yields no results.
Unfortunately, the Do Not Call does not apply in my case. The do not call list excludes calls which are not commercial or do not include unsolicited advertisements.
Political surveys are not commercial in nature and do not include unsolicited ad's. Can you say LOOPHOLE?
Time to head to Verizon Spam Control to block the number.
If you use a different cell phone company, check to see if you can block numbers.
