Blocking Your Cell Phone Number Permanently:

The most permanent solution is to request a "line block" from your cell carrier.

  1. To do this you simply need to call the customer service for your specific provider and they can block your number. When you do this your number will never show up to anyone.
  2. To call your wireless customer service to block your number, just dial 611 from your cell phone and you will reach them.
  3. If there is a situation where you want your number to show up, you will still have an option. When you have a permanent block on your number you will need to dial *82 before dialing the number you are calling. When you do this your phone number will show up just once for that specific call. (Ex: *82 (555) 555-5555.)

how to block phone numbersBlocking Your Cell Phone Number Temporarily:

Sometimes you may want to block your number from caller ID for a specific call. You might not want someone to know that you are trying to reach them for the 15th time in a row, or you might be calling a business and might not want them to know your number. Whatever the reason, it's easy to do.

  1. If you want to block your number on a call-by-call basis you need to dial *67 before dialing the number. Ex *67 (555) 555-5555.
  2. When you do this you will not have any feedback that it worked. If you want to test it, just call your home phone, or anther phone that has a caller ID from your cell to confirm that the block worked.

One important thing to remember is that your number will not be blocked from emergency services or any toll-free number - it only works when you call businesses and individuals. 

Another strategy you can use is caller ID spoofing, which displays a different name and number than the one you're calling from. Be careful when signing up for a caller ID spoofing service - some fake caller ID services are illegal. There are many other caller ID tricks; however, it's important to be cautious. Anything that shows the caller ID a phone number that belongs to somebody else could be illegal. 

Finally, if you want to have people call you while keeping your main phone number private, you can get a call forwarding service. The person calling you will dial a telephone number that will then connect to your phone - without them knowing your real number.  There are many call forwarding services - a famous one is Google Voice.
