The code that hides your phone number when making a call in North America is *67. When you dial this code before a phone number, your call recipient will see "Private," "Anonymous," or "Blocked" on their caller ID instead of your actual number.
To block your number from being displayed temporarily for a specific call: Enter *67. Enter the number you wish to call (including area code). Tap Call.
No, *67 doesn't work in Australia; the correct code for per-call caller ID blocking on mobile phones is #31#, while 1831 (or sometimes 1832 to show your number) works for landlines, but you can also set a default in your phone's settings or use carrier-specific codes like Telstra's. For hiding your number in Australia, use #31# before the number, or check your phone's settings to block it by default for all calls.
*67 is a calling feature that allows you to hide your phone number when making calls. When you dial *67 before a phone number, your caller ID is blocked, and the person you are calling will see "Blocked," "Private," or "Unknown" on their caller ID instead of your actual phone number.
Steps to Hide Your Number with *67
When you use *67, your number will appear as “Private,” “Anonymous” or “Blocked” on the recipient's screen.
Yes, \*67 still generally works on most U.S. carriers to block your caller ID for a single call by dialing \*67 followed by the number (e.g., \*675551234567), showing up as "Private" or "Blocked," but it won't work for toll-free or emergency numbers and may be blocked by some recipients. This per-call feature hides your number but doesn't change your phone's settings permanently, and you can use other methods like carrier settings or apps for consistent blocking, notes USA Today and Times of India.
Yes, *67 only hides your number from the person you're calling but doesn't make you completely anonymous. Phone companies and authorities can still trace the call if necessary. It only provides privacy on the recipient's caller ID, not complete anonymity.
Enabled: You can display your Caller ID for a single outgoing call. Press *67, call the destination phone number, then press #. Disabled: You can hide your Caller ID for a single outgoing call. Press *82, call the number, then press #.
Using *67 blocks caller ID from appearing on the recipient's phone, but it does not make the call untraceable. Law enforcement can request call records from phone carriers to identify the originating number, even if *67 was used. Trace requests typically require a valid legal basis, such as a subpoena or court order.
Hang up the receiver, pick receiver back up and press *57 (star-five-seven) immediately following a threatening or harassing phone call, and before making another call. To activate the feature on a multi-line phone (more than one phone number):
Yes, *69 can work in Australia for Call Return on some networks like Optus, but Telstra uses *10# for a similar service, and it often involves per-use charges; however, mobile networks often store caller ID, making landline-style codes less universal, with features depending on your specific provider and service plan.
How to figure out a no caller ID number. You can uncover an unknown caller ID by using the *69 or *57 feature codes, third-party apps, or by contacting your phone service provider. Unknown callers could be hiding their identity to try and scam you, so it's important to check them before you fall victim.
*69, a code widely available in North America, allows you to redial the last incoming call that you missed. The service is provided by most telephone service providers and operates by storing the caller's phone number, allowing you to quickly connect back to them.
Did you know there are similar numbers you can dial to respond to these anonymous callers? The first one is *69, which traces the number of the last person who called you. It works even for anonymous or hidden calls, so you can get the phone number and the exact time they called.
*69 will dial the number of the last party to call you so long as they did not block caller ID and the number reported is valid. This is also carrier dependent. it's rather pointless today as you can dial the last number that called you by tapping on the last call in your call log.
To make your number unsearchable on the internet, you'll have to remove it from sites such as people search platforms and other data brokers, public records, and social media platforms. By doing so, your phone number will also be removed from Google, as pages that are removed will be dropped from Google's index.
While *69 may work in some cases, a better option is to:
No, you *cannot use 67 for text messages; it only works for hiding your caller ID on phone calls by displaying "Private" or "Unknown," but it won't hide your number for texts. To send anonymous texts, you need to use built-in phone settings to hide your number (if available with your carrier) or use third-party apps like Google Voice or Hushed for a separate number.
Dialing *77 on your phone activates Anonymous Call Rejection, blocking incoming calls from private or blocked numbers, making anonymous callers hear a message to hang up and try again. It's a landline/VoIP feature (like AT&T, CenturyLink) to stop spam/prank calls but can sometimes vary by carrier or state, potentially connecting to emergency services (like *87 to turn it off).
Signs someone has blocked your number
Dialing *68 will disable the Caller ID for the next outbound / external call only. Selecting a line and dialing this feature code will result in a prompt on the phone display as well as an audible message: "Caller ID is BLOCKED for the next outbound call only." We hope you find this new feature code useful!
Unfortunately, if the user is using *67, there isn't a way to figure out what the number they are calling from is. Depending on your phone, you might have the option to block that call instance from happening again, but we're unsure if this would block all unknown numbers.
If you want to stop phone tracking, you can change your phone settings, switch to a private browser, configure your app permissions more carefully, or use a VPN.
Solution. Call trace allows you to dial the code *57 to trace the phone number of a call that was received. This service is used to trace harassing calls which warrant law enforcement or legal action. If you do not intend to take legal action, then an alternative is to use Call Return with *69.
