    I always put my numbers on https://www.donotcall.gov but it is currently unavailable due to government shutdown.

    Verizon is very quick to sell new numbers.

    I just press the silver button on the top of the phone and go back to whatever I was doing.

    I heard that putting your number on donotcall.gov was a scam... no?

    Not a scam at all. It worked very well for many years, before the advent of robo-dialers. I shudder to remember the amount of junk calls that I got before the DNC list was implemented.

    No, it's a legit government site voted into law and paid for by tax dollars.

    My new Verizon number went from five a day to zero in less than a week.

    I have never used it, but trapcall.com offers that service. You forward your unknown calls to them, and they forward them back with the real number. It works because they have a toll free number which gives them more billing information about the number calling.

    As emseven mentioned, it's a legit site. It'd be rather difficult for a scammer to obtain a .gov domain.

    With that said, just because you're on the registry doesn't mean telemarketers all pay attention to it. Worst culprits seem to be local companies robocalling; tree services, etc. Also plenty of donation solicitations, they (and politicians) are of course exempted.

    Does anyone have any idea what the difference is between

    No Caller ID

    and

    Withheld


    Get a lot of hang ups with No Caller ID, and Withheld are more likely to have someone on the other end?

    "No Caller ID" is just what it sounds like, the carrier didn't send anything.

    "Withheld" *is* the CID string that was sent.

    Either way don't answer....you have to know that some people do answer and fall for their scam or buy their product, otherwise they would stop.

    I've used it and highly recommended. There may have been a small fee to sign up but it was only US$5 or so a month. I had some middle schoolers start calling me during the day and night for no reason. When I got trapcall it unblocked their number and I called back and talked to their dad. I haven't had a call since. :)

    still don't get that No Caller ID or Withheld.

    I've had someone on the end from both in the past...

    Withheld calls come from several companies I deal with, and NO Caller ID was once a call from the breakdown truck coming to pick up my broken down car, which was his mobile phone, so why is there both and not just one. Both withhold their number?

    Perhaps different carriers have it set up to respond differently when ID is not set up or when one is being blocked? Perhaps people/companies manually set theirs to something custom, which can easily be just "Withheld" or "Unlisted" or whatever else they might want.

    I'd love to know how they can do that. Even from mobiles.

    Change caller ID? Often the carrier will offer the option for that or even to remove caller ID. Then also other apps can be used like Skype or something else where another number can be used to make a call or a number can even be spoofed.

    Don't know what's so hard to understand...

    "No Caller ID" == the carrier didn't send you CID information or the phone didn't detect it.

    "Withheld" == the carrier sent you CID information, it was the string "Withheld". Other strings (or any, or none) is possible.

    See http://en.wikipedia.org/wiki/Caller_ID#Operation

    Contact your cellular provider or see post #13 above. Others recommend Google Voice.

    I had something like that in the 90's. The caller would get a recording that they needed to unblock their number. I think they could press "1" to unblock it and there may have been a few other options.

    I remember that, but I think that was a provider/carrier option that could be requested. Not sure if any mobile carriers really provide that.

    Try calling your carrier. it may just apply to landlines but when I had a landline before I went to just my cell, I had that option on my house phone.

    Do you have verizon by any chance? Not sure if this works but
