11 Codes to Check If Cell Phone is Hacked or Tapped

Are you wondering what to dial to see if your phone is hacked? Welcome. All carriers have a data forwarding feature that allows you to configure your phone to redirect calls, messages, and voicemail to a different number. Unfortunately, cybercriminals could exploit this, causing various security risks.

That is why these special codes (also known as USSD codes) for hacked mobile phones are essential. They can help you identify if and where your calls and voicemail are being forwarded, revealing signs of phone tampering or hacking. Rest assured, we’ll also provide the codes to stop it.

Read on to discover how to detect if your phone has been hacked and the best ways to stay safe.

Quick list of codes to see if your phone is being tracked or is hacked

5 signs to know if your phone is hacked or tapped

Here are the signs to detect if your phone has been tampered with or infected with spyware:

• Battery draining faster
• Consistent sluggish performance
• Unfamiliar logins
• Abnormal storage use
• Mystery apps you didn’t install
• Suspicious calls or texts
• A sudden surge in data usage
• Annoying spammy pop-ups

If you’ve recently noticed two or more of these signs on your phone, you should investigate the issue immediately.

Understanding USSD codes: The easiest way to identify a hacker 

Unstructured Supplementary Service Data (USSD) is a global communication protocol that mobile phones use to interact with a network operator’s systems. A USSD code is a string of characters, typically starting with an asterisk (*) and ending with a (#), that facilitates network communication. These codes can vary by carrier, device, and even region.

USSD codes are helpful in addition to the basic functions, like changing your PIN or checking your balance. They can also redirect your calls and voicemail to a different number.

Moreover, USSD codes can help you see if your data is being forwarded or your phone is hacked. Thankfully, there are codes you can use to stop it.

Codes to check if your phone is tapped or hacked

A recent report by Deloitte reveals that 67% of smartphone users are apprehensive about the data security and privacy on their devices. So, whether or not your phone is hacked, it’s worth checking. It only takes a few seconds and doesn’t involve additional preparation.

How to use USSD codes to check if your phone is tapped

Here is a quick guide on using USSD numbers to see if your phone is hacked.

1. Open your phone dialer: Navigate to the ‘Phone’ app and find the dialer.

2. Enter the code and tap call: Input the USSD code on the dialer and tap the call button to retrieve the required information.

3. Check the information you retrieved: A pop-up menu will display the requested information. For example, enter *#06# to get your phone’s IMEI number.

Codes to check if your phone is tapped or hacked and how to stop it – Detailed list

The following codes will help you check your phone forward settings and safeguard your privacy.

1. *#06# – To retrieve your phone’s IMEI code

You can dial *#06# to get your phone’s International Mobile Equipment Identifier (IMEI) number, a 15-digit unique identifier for every phone.

Remember to keep the IMEI number private. A malicious actor can block your phone, making it unusable on any carrier.

Moreover, if a hacker obtains your IMEI number and SIM ICCID, they could clone your phone and intercept your SMS messages.

2. *#61# – To check if your missed calls are forwarded to a different number

All mobile phones have conditional and unconditional forwarding. Conditional call redirecting occurs when you meet certain conditions. For example, the condition might be not picking up a call. Malicious actors can intercept this feature by configuring your phone to forward calls to a different number.

You can dial *#61# to see if your missed calls are redirected to another number. You’ll see the number receiving your unanswered calls if the feature is enabled.

SMS call forwarding will also appear under the same menu. This feature works similarly to call forwarding but applies to SMS messages. It also poses a serious risk, as hackers could intercept crucial messages, such as verification codes for logging into your accounts.

If the number looks unfamiliar and you don’t recall configuring this call-forwarding feature, it clearly indicates that someone is intercepting your calls and messages.

3. ##61# – To deactivate missed call redirection

If you detect an unknown number is receiving your missed calls, just dial ##61# to disable the conditional call forwarding feature. To check if you’ve turned it off, dial *#61# again to check the settings. The interrogation message should indicate you’ve disabled the feature.

4. *#62# – To check if your calls are being redirected when your device is turned off or has no signal

This is another conditional redirection feature that only happens when your phone is completely turned off or doesn’t have signals to receive incoming calls.

The *#62# code will indicate whether this feature is activated. You’ll see the number receiving your missed calls if it’s active.

5. ##62# – To disable call forwarding when your phone is off

If your phone redirects missed calls when your phone is out of reach, dial ##62# to deactivate this feature.

6. *#21# – To check if your calls are being redirected

This USSD code indicates if unconditional forwarding is enabled on your phone. The menu is similar to the other examples above but applies to all calls.

Unconditional forwarding, or call diverting, is a detrimental type of hacking. Unlike call forwarding, call diverting redirects all your calls and messages. If this feature is active, you won’t be able to receive any calls on your phone.

Although call redirection allows you to receive calls before they move to the secondary number, call diversion sends them to a different number before reaching your phone.

7. ##21# – To deactivate unconditional redirection settings 

If you cannot receive calls or notice a call forwarding icon on your phone’s status bar, dial ##21# to disable all unconditional redirection settings.

This will enable you to start receiving calls and messages. You should also contact your provider to check if suspicious activities are associated with your SIM card.

While you might not be able to know the calls and messages you missed, you should change passwords to accounts associated with your phone number.

8. *#004# – Displays all the redirection settings on your phone

This is a useful USSD code for checking your device’s redirection settings. It will display a long list with data in your incoming calls, SMS messages, and voicemail, showing you if they are redirected and which number they go to.

It applies to conditional and unconditional forwarding, acting as a unified solution for the above USSD codes (*#61#, *#62#, and *#21#). If one or more of these codes don’t work, it should do the trick.

9. ##02# – To deactivate all conditional and unconditional forwarding settings 

This is a master code that handles all the work in one swipe. Just dial ##002# to deactivate your phone’s conditional and unconditional redirecting settings.

This code will enable you to remove all previously redirected messages and voicemails, protecting your data from hackers.

10. *2767*3855# or *#*#7780#*#* – To factory reset your phone (Android only)

If you’ve disabled your phone’s redirection settings but still suspect it’s been hacked, you can perform a factory reset to wipe it clean.

So, if you are worried about spyware and other viruses on your phone, dial *2767*3855# or *#*#7780#*#* to fully reset it. This will delete all the settings, data, and third-party apps (including hidden spyware installed to spy on your cell phone).

Besides, here are some alternative ways to factory reset your phone:

• Go to Settings > Backup and reset > Factory data reset for Android.
• For iOS, go to Settings > General > Reset iPhone.

11. *#67# – To check for call forwarding number

This code shows you the calls and messages sent to other numbers when you reject the call or on another line. Dial ##67# if it’s an unknown number.

Bonus: Other useful USSD codes

Many other USSD codes are useful for other purposes, some of which are listed below:

• #31#: This code hides your phone number when making a call. To use it, dial #31# followed by the number you want to call.
• *#*#4636#*#* or *#*#197328649#*#*: This code shows the device information, Wi-Fi details, and usage statistics (applies only to Android devices).
• *3001#12345#: Activate the phone’s field mode and show information about local networks, signal strength, and cell towers.
• *#*#1472365#*#*: Indicate your phone’s ability to locate and connect to GPS satellites (available only for Android devices).
• *#*#34971539#*#*: Shows your phone’s camera factory information.
• *#*#232338#*#*: Displays your phone’s Media Access Control (MAC) address when Wi-Fi connects.
• *#*#4636#*#* or *#*#197328640#*#*: Provides your phone’s factory information, Wi-Fi details, and usage statistics.

Can an antivirus program protect my phone from being hacked?

Having a list of codes to see if your phone is hacked is good, but you, ideally, also need a security program on your device all the time. An antivirus is an essential security tool as it monitors your phone’s operating system and storage in real-time. If it detects a malicious application, it quarantines it to prevent further damage.

Additionally, an antivirus can prevent hacking through alerts. For example, you might receive an email with a malicious attachment that might install a keylogger on your phone.

How can a phone be hacked?

Here are the most common tactics cybercriminals use to hack phones:

• Phishing: Fraudsters manipulate unsuspecting users into revealing personal information by exploiting their fear or curiosity. Popular phishing targets include online document and storage services, webmail, internet portals, and financial service sites.
• Unsecured Wi-Fi networks: Hackers often exploit unsecured public Wi-Fi networks to target unsuspecting users, so be cautious when using them.
• Tracking software: Some malware types, like stalkerware, can track you using GPS, messages, call logs, browser history, images, and more. Unfortunately, this malware can be concealed behind seemingly harmless apps.

Tips to stay safe from phone hacking

Here are some tips to keep your personal information and device safe:

• Monitor your phone’s performance regularly and assess your device’s battery health. If it is losing charge abnormally, try one of the codes above to see if you’re being hacked.
• Open the app list and check for suspicious apps you didn’t install. Mobile malware and spyware often disguise themselves as innocent-sounding apps like ‘Mobile Gallery.’
• Avoid downloading apps from unknown sources, accessing malicious sites, or using public Wi-Fi networks. These are some of the common places hackers target unsuspecting users.
• Never leave your phone unattended, especially in public, as installing spyware only takes a few minutes.
