10 Code to Check if Phone is Hacked or Tapped (2024)

Sommaire

In this guide, I have shared various important codes to check if your phone is hacked or is being tapped. Phone tapping is a criminal offense (unless performed by police) to overhear someone’s telephonic conversations.

When a phone is hacked by miscreants, its data and other important information may be stolen. The device can also be accessed by miscreants after they hack it. Thankfully, certain codes, called USSD codes, allow a user to know whether their phone has been tapped or hacked.

What are USSD Codes?

USSD stands for Unstructured Supplementary Service Data. Users can access security-related information on their smartphones by entering USSD codes using the phone dialer app.

1. How to Know if Someone is Listening to Your Phone Calls?

Dial *#61# on your phone dialer to find out if someone else is listening to your calls or has access to messages that you receive on your phone.

If you find any discrepancies in the call forwarding, you can disable the settings by dialing ##61#.

2. Who Receives Your Phone Call When Your Phone is Unreachable?

Dial *#62# to find out who receives your phone calls and text messages when your device is unreachable.

To reverse the setting in case you notice the hack/tapping, enter the code ##62# from your phone number.

3. Who Receives Your Phone Call if You Are Busy on Another Call?

When you are busy on a call another call arrives on your number but it is redirected to the hacker’s number. To know if that is the case, dial *#67#.

To stop calls from being redirected to other numbers, disable the setting by dialing ##67# using your phone app.

4. Universal Code to Know Who Taps into Your Phone Call When You Are Busy/Unreachable/Do Not Answer

Instead of using different USSD codes for different purposes, here is one code you can use to know if your phone has been hacked/tapped.

When you dial *#004# you will know who is receiving your calls when you are busy on another call or unreachable. If you see any unauthorized settings changes, revert it to the default by dialing ##004#.

5. Understanding Unconditional Forwarding Code

In unconditional forwarding, the victim doesn’t know if his calls are being forwarded to someone else. Whether the victim receives the call or not, the incoming call is forwarded to the hacker.

The unsuspecting victim won’t even know if calls are immediately forwarded to someone else. Thankfully, there is a diversion code to detect this hack and revert it.

6. How to Use The Diversion Code?

Using code *#21# you will know if someone else is accessing your calls and messages via unconditional forwarding. To change the settings, open the phone app and dial ##21# to erase all hacked unconditional forwarding settings.

7. Net Monitor Utility Code

The code is *#*#197328640#*#*, and it provides information about all the information received or sent from the phone. It even includes the phone’s location.

Dial the above code on your phone dialer.
From the menu, select UMTS Cell Environment > UMTS RR Information,
Note down the cell ID number > Tap on the back button to go to the main menu.
Now, tap MM Information > Serving PLMN. Also, note down the local area code visible on the screen.
On your PC/phone browser access any net monitor website.
Enter the cell ID number and local area code you obtained.

You will know if any other unauthorized number has access to your phone calls and messages on your phone.
