Сodes to check if the phone is tapped or hacked

When someone hacks or taps your phone, your calls, messages, and other data can be forwarded to another person. But don’t panic. If you suspect your phone has been hacked or cloned, open a dialer pad and get all your doubts cleared. Here are the codes to test if your phone has been hacked, so you can stop or unhack it.

Code to show your IMEI: *#06#

Every mobile device has its unique international mobile equipment identity code, or IMEI. Now, the IMEI shortcode has nothing to do with your phone being hacked, but having it saved or written down somewhere safe is a must to file a police report when your device has been compromised. So, before checking any cell phone hacking codes, learn your IMEI by dialing *#06#.

IMEI shortcode is the first code to check to file a police report when the phone is hacked

Show if anyone catches my unanswered calls: *#61#

Scammers can catch your incoming calls and then redirect them to a different line. This is known as conditional call forwarding. You should begin to smell a rat when your phone rings once, and there are no other traces of incoming calls. Or you may not even notice any forwarding as it happens when you simply miss the call. By the way, hackers can use this type of attack to forward your messages to another number.

Show if anyone catches unanswered calls

Using the *#61# code will show you if anyone receives your calls whenever they go unanswered. If you find any strange signs, you can automatically erase these settings by dialing ##61#.  

Code to check call forwarding status: *#62#

Dialing this phone tapping code will answer the question of who receives your text messages and calls when your device is switched off, or you’ve lost connectivity. If this code returns a number, don’t panic — it may simply be your voicemail. But if not, dial ##62# and remove the ears of these hackers and scammers from your calls.

Code to check for call forwarding number: *#67#

This code informs you about the calls and messages sent to other numbers when you’re on another line or reject the call. The response you receive from entering this code will reveal if someone is after you. If it's an unknown number and not your own, simply dial ##67#.  

Code to check all call forwarding information: *#004#  

After dialing this code, you’ll have the full picture on conditional phone forwarding. In other words, you will see who receives your calls or messages when:

  • You’re out of reach
  • You’re busy on another line
  • You reject the call
  • You don’t reply to a call.

So feel free to use this code instead of *#61#, *#62#, and *#67#. You can also erase all conditional forwarding settings by dialing ##004# from your original number.

Code to turn off all forms of phone redirection: ##002#

Once you’ve established who your calls are being forwarded to, you can turn off all call forwarding. To do this, simply dial ##002#.

Code to turn off all forms of phone redirection

You’ll see the confirmation on the screen that the following forms of call forwarding have been successfully erased:

  • Voice call forwarding
  • Data call forwarding
  • Fax call forwarding
  • SMS call forwarding
  • Sync data circuit call forwarding
  • Async data circuit call forwarding
  • Packet access call forwarding
  • Pad access call forwarding.

Code to check if phone is tapped: *#21#  

Some hackers go further and forward all your calls and messages, no matter if you’re available or out of reach. This type of attack is called unconditional data forwarding or diversion.

 

Such activity is harder to spot. A diversion cancels and redirects calls to another line without even allowing your phone to ring. As a result, it never shows up on your phone bill (unlike conditional forwarding when your phone number technically receives the call).

Code to check if phone is tapped

Dial *#21# and find out if your phone has been hacked this way. If you see that it was, just dial ##21# to erase these settings.

Code to show unknown connections and tracking (for Android): *#*#4636#*#* or *#*#197328640#*#*

Hackers can track your location through your phone. Press *#*#4636#*#* or *#*#197328640#*#* to see if anyone is watching your movements. These are Utility Net Monitor Codes. Dialing these codes can tell you if you’re being tracked or monitored through your mobile phone.

Code to show unknown connections and if someone is tracing you (for iPhone): *3001#12345#*

Similarly, hackers can identify and track your movements on your iPhone. Apple gave Field Test Mode a refreshed look to show you a snapshot of valuable information with the launch of iOS 14.

 

Filed Test Mode is a feature that gives you detailed information about your cellphone’s signal and connection. It’s particularly useful to engineers and cellular operators, but you can use it to see if you’re being traced. Dial *3001#12345#* to open the Field Test app.

 

Once you dial *3001#12345#*, you will be redirected to your connections data storage.

Code to show unknown connections

Code to find your phone if lost or stolen (for Android): *#*#1472365#*#*

This code shows your GPS location. You can use it to test if your GPS information is correct or to find and recover your lost phone. Note: This code works if your phone’s GPS is on.

Code to show the firmware details of your phone’s camera (for Android): *#*#34971539#*#

Checking your mobile phone’s camera details can reveal valuable information, like the number of cameras your phone has and so much more. More importantly, it can tell you if someone has tampered with your camera to spy on you. Use it to ensure that no one has compromised your privacy in this way.

Code to show the MAC address information (for Android): *#*#232338#*#*

Every phone has a unique Media Access Control address, commonly known as the MAC address, which helps identify it when connected to a network. If you suspect you’ve been hacked, dialing *#*#232338#*#* and comparing the MAC address with your network can help you find out.

Code to factory reset your phone (for Android): *#*#7780#*#*

If you’re giving your phone away or selling it, performing a factory reset may be helpful. A factory reset erases all the information, settings, and data on your phone — including data related to your apps and accounts like Google. This protects your privacy and makes it easier for the person who’ll be receiving your phone.

Code to wipe your smartphone clean of all data (for Android): *2767*3855#

If you’re concerned that someone may have hacked your phone to spy on you and want to rid your phone of any viruses and malware, consider performing a hard reset. This will remove most viruses on it, as it completes a complete wipe of your phone. It will also remove and reinstall all firmware on your device. Always ensure you back up important files before performing a hard reset.

Wrapping up

Using these basic numbers you dial to see if your phone is tapped can help you identify when a spy is watching you or has bugged your phone remotely, so you can get rid of the bug or untap your phone. Yet, depending on your service provider, some of them may not work properly on your device, and you’ll get the “Invalid MMI code” or “failed” notification.  

 

To protect your phone from getting tapped, be careful with giving it to strangers who need to make an emergency call. You can always suggest dialing the required number on your own and using a loudspeaker.
