Just last week, 8,261 people got Nomorobo protection!

It's great! Let the phone ring once. If it rings again, it's real. In not, we say, "Gee, Thanks, NOMOMOBO!

It works

Trying to stop or at least limit Robocalls almost became a part time job for me. I would diligently try to use their "press 5 to be removed from our list" [yeah, THAT works!], & even more diligently report the numbers/caller ID in complaints to the Do Not Call Registry. Pretty much to no avail & a losing battle. Then I read about Nomorobo. Gave it a try & OMG, what a difference! An IMMEDIATE difference! A real Godsend --- The peace is wonderful. One little ring & then nothing. Thank you so much!!

This is a service of the telephone company, right? They provide the phone service and they are the ones to ensure they are used properly, right?No?The telephone company doesn't care if their service is used by scammers and annoying callers?They provide a Caller ID so we can decide if we want to accept the call? But only if we go to the phone and examine the caller and number? We still gotta go to the phone, right? Why can't somebody just intersept those calls and stop the ringing?Somebody did?! And it wasn't the phone company?An independent service? And it's free?THANKS! Nomorobo! You enhanced our quality of life and for bringing peace to so many >>> you should receive the Nobel Peace Prize.

Peace has returned to the house. No more ringing only to get a robo voice on the other end. I love this service.

No, I'm still getting the calls.

You are blocking about ten calls a day. This is great. What is the system for my suggesting new numbers to block? Thanks. May I suggest you have a service that requires the caller to type in two random numbers requested by Nomorobo. This would block more robo clls including politicians.
