Blocking your caller identification means preventing your name and phone number from being displayed on the receiver’s screen when you make a call.
Some people just want the privacy of not having their phone number or name made available to the people they are calling, and blocking caller ID can help with this. There are ways to block your caller ID permanently, or just for specific calls, but it does depend on whether you are using a landline or a cell phone.
Most mobile phones provide the option to turn caller ID on and off, and this should usually allow you to get through to phones that have blocked your number as well. Phones are configured differently and can even vary between carriers, but for cell phones that offer this feature:
- On iPhones: go to Settings > Phone > Show My Caller ID. Then turn off caller ID. This will work for many carriers but not all; for example, Verizon requires that you change these settings on their website rather than on the phone itself.
- On Samsung phones: go to Apps > Settings > My Device. Then select Call, and from there Call Settings > Additional settings > Caller ID. Then select Hide Number.
- On HTC phones: from the Menu, select Settings > Call > Additional Settings > Caller ID. Select Hide Number.
- On LG phones: from the Phone application, select Call Settings. Find and select Caller ID, and then select Hide Number.
- On Blackberrys: from the Phone application, select the Blackberry button > Options > In-Call Settings. Under Restrict My Identity, select Always. Press the Blackberry button > Save.
