A Quick No Caller ID Trick: *67
One of the quickest and easiest ways to hide your number from the person you’re calling is to use the *67 trick when you’re dialing. That will make your number register as ‘Private’ to the person you call. You’ll have to do it for every call you want to make with a hidden number, but if you only need to hide your number now and then, this is a good option for keeping your number private.
Use the Hide Number No Caller ID Trick
Almost all Android devices on most mobile carriers offer the option of hiding your number by default, making it unnecessary to input *67 every time you call. Here’s how to block your cell phone number using your phone’s built-in Hide Number feature. This no caller ID trick will make it so that your number never shows up when you ring someone. Instead, it will display as Blocked, Private, or No Caller ID. If you want your number to display again temporarily, you can preface the number you’re calling with *82. Alternatively, if you want to turn off your number block, repeat the steps above, and at the last one, select Network Default or ShowNumber.
Ask Your Carrier To Block Your Number Directly
If your device doesn’t have the option to block your number directly, then you may need to ask your carrier to do it for you. Sometimes this can be completed with the official application.
Verizon App: Instructions for how to block your cell phone number on Verizon. AT&T App: Details on how to make your number unknown on AT&T. Sprint App: A guide on how to call someone without showing your number on Sprint. T-Mobile App: Information on how to call someone anonymously on T-Mobile.
If the above call blocking services don’t support your device within the official apps, try contacting your carrier directly. They can usually block your ID for you.
Use a Burner Number
If none of the above no caller ID tricks work, you can buy a prepaid phone, often referred to as a burner or disposable number. Many paid-for services let you route your calls, texts, and picture messages through a temporary number.
Limitations to Hiding Your Phone Number
There are some calls that you can’t hide your number from. Toll-free services and 911 emergency services will always be able to see your number, whatever you do. Some third-party applications can allow someone to get around any number obfuscation you put in place, so none of these methods are guaranteed.
