Make Anonymous Cell Phone Calls

With cellphones, now everyone’s a walking caller id. Here’s how to make a call on your mobile without revealing its number.

From a tipster on Lifehacker:

I needed to call someone from my cell but I didn’t want them to get my number from their caller id. I know to use *67 at home when I want to do this but cell dialing is different – you don’t get that double dial tone to let you know you are now restricting your number. With your cell, just start the number you are calling with the *67, as if the phone number begins with those three digits. The important thing to remember is that you will need to put the 1 in before the area code, as cells don’t normally need the 1.

For example, enter *6719175551212 before hitting the talk button will lead the receivers caller id to read “restricted.”

    this smells highly carrier-specific. try it out calling an office phone or something before you start crank calling the ex.

    I found this on …it is an alternative to restricting your number, I know I don’t pick up when I cannot see caller ID. This way you get the person to pick up and you number dissapears after a week.

    “Safe Talk is a new service in the UK that allows you to generate a temporary phone number to use for 7 days to give to people you don’t trust/know.

    It’s simple – text CALL to 80876 and get a temporary number that diverts to your mobile phone for 7 days, and keep your own number safe – until you know if they’re nuts or not!

    Each number costs £1.50, and you can choose to either extend your usage of the number after seven days or cancel it. Avoiding confrontation seems very British-y, but this service should do well in the US for daters.”

    Jules says he could do it on his T-mobile. He writes:

    “Hey, love the site. I’ve been reading since the first day, but since I’m shy I’ve never commented before ;-)

    Anyhoo, I’ve always wanted to make my cell phone number private, so I tried what you suggested. I’m with T-Mobile, by the way.

    I did a test call from my cell to my office phone and my info came up. I then called using *67-1-(XXX) XXX-XXXX and lo! I came up as private.

    So it works on T-Mobile, at least.

    “What you say in this article is not news. The phone companies introduced *67 at the SAME TIME that they introduced Caller-ID, which is decades ago.

    Personally, I’ve been using *67 ever since I got my first cell phone, 14 years ago.

    Also, you don’t need a “1” when dialling on your cell phone. You never need a one and using *67 doesn’t make it so that you need a one. All the numbers in the memory in my cell phone start with *67 and none of them has a one.

    Think back to the days before you needed a “1” on your landline phone. Why did they introduce it? If you think about why they introduced the “1” on the landline phones you’ll realize why you NEVER need a one on a cell phone.

    “I just read the new post about anonymous cell phone calls, so I thought it might be a good idea to send you the link to this site my friend told me about. It’s called It lets you make phone calls from the site. You type in what you want to say, and a robot voice will do the talking for you. There’s a “premium” option with more robot voices and customizable caller ID. I’m thinking about getting it and prank calling my entire office.

    Have fun!

    Worked with my Cingular phone this morning, thanks for the tip.

  8. Jillsy says:

    Works on Verizon, but the call only goes through if I put “1” before the phone number.

  9. Bubba Barney says:

    I tested it on Qwest/Sprint and it worked. Didn’t need to use a 1 either.

  10. Yes, but does it cost something to use this feature?

  11. Treved says:

    I have Verizon, and I NEVER use the “1”, and I never get charged.

    What number shows up on their bill… if any? When I block caller id from my cell, I am concerned about my # showing up on their bill. I have the same concern here. Anybody know?

    I know I am late to this conversation because I just stumbled across it. No one here mentioned the one fatal flaw in using *67. Although it does block your phone number from appearing on the persons Cell Phone Caller ID, it nevertheless DOES appear on their phone detail. In fact, someone called me twice the other day with a blocked number but they hung up both times. I went online and looked at my bill. THERE IT WAS…the number of the person who called and hung up. Be careful!
