USSD codes offer a direct line for Android phone users to access hidden features and useful information. They’re a bridge between the phone and the network services it can tap into. USSD stands for Unstructured Supplementary Service Data, which might sound complicated, but it’s simply a quick access code you enter on your phone’s dialer. These codes start a real-time connection with your mobile network—imagine it as a conversation between your smartphone and the service provider. This Man-Machine Interface (MMI) lets you get information or request services without navigating through apps or web pages.
Here are the most common USSD codes and their general purpose. Remember to use these with caution, as some codes can alter your device settings.

Unlock Your Android’s Potential with USSD Codes
What Are USSD Codes?
USSD codes, also known as “quick codes” or “feature codes,” are special character sequences that can be dialed on your Android phone to access hidden features or information. These codes are often used by technicians and developers, but anyone can use them to unlock various functions on their device.
Common USSD Codes and Their Functions
| Code | Function |
|---|---|
| *#06# | Display IMEI number (International Mobile Equipment Identity) |
| ##4636## | Display phone information, battery status, and usage statistics |
| ##7780## | Factory reset (WARNING: This will erase all data!) |
| 27673855# | Format device (WARNING: This will erase all data!) |
| ##34971539## | Show camera information |
How to Use USSD Codes
- Open your phone’s dialer app.
- Enter the USSD code.
- Tap the call button.
The function associated with the code will usually be executed automatically. Sometimes, you might need to press the call button again or follow additional prompts.
Important Notes
- Not all USSD codes work on all Android devices. Some codes may be carrier-specific or device-specific.
- Use caution when entering USSD codes. Some codes can perform irreversible actions, like factory resetting your phone.
- For a more comprehensive list of USSD codes, consult your phone’s manual or search online for codes specific to your device model.
By using USSD codes, you can access hidden features and settings on your Android phone, allowing you to customize your device and troubleshoot problems. Just be sure to use them responsibly and with caution!
Advantages of Using USSD Codes
One of the biggest pluses of using USSD codes is that they don’t need data. This means you can retrieve information or perform specific phone functions even when you’re out of data or in a spot with poor internet connectivity. They’re also immediate, delivering the info straight to your screen without delay. Since they’re built into the GSM network standard, these codes are universal across Android devices, making them incredibly handy no matter what Android phone you own.
Common Android USSD Codes
USSD codes vary by country and network provider, but there are a few standard ones that tend to work universally on Android phones. For instance:
Check IMEI Number:
*#06#
The IMEI is a unique identifier for your phone. Handy for when you’re dealing with phone repairs or if your phone is lost.Access Device Information:
*#*#4636#*#*
This will bring up detailed information about your phone’s battery, usage statistics, and Wi-Fi connection.
Remember, while these codes are useful, not all of them might work on every Android device as manufacturers can sometimes disable or alter them. It’s a smart move to use these codes wisely and ensure that they’re compatible with your specific phone model and network provider.
Accessing Device Information
Secret USSD codes for Android devices unlock a wealth of data about your handset. They’re handy shortcuts for tech enthusiasts to get device information quickly.
Retrieving IMEI and MAC Address
Your phone’s IMEI (International Mobile Equipment Identity) is a unique identifier, and the MAC (Media Access Control) address is specific to the phone’s network interface. To fetch your IMEI, dial *#06#, and it will appear on screen. For the MAC address, typically, one would navigate through the settings menu, but a USSD code shortcut for this information, if available, varies between manufacturers.
Checking Battery and Storage Status
Your battery health and storage data are vital for keeping your Android running smoothly. While Android typically doesn’t have a USSD code to check battery status, some manufacturers might offer a code that gives you a direct look at battery information and storage statistics. Otherwise, this data is commonly available through the settings menu under ‘Battery’ and ‘Storage.’
Android Secret Codes for Hardware Testing
These codes can test various hardware components to ensure they’re working correctly:
- Camera Firmware: Some Androids let you check the camera firmware, which is the software helping your camera function, with a code like
*#*#34971539#*#*. - System Dump: To collect system dump data, use the code
*#9900#. This can help with debugging by gathering system logs and other info. - Hardware Version: To get phone info about the hardware version, try
*#*#2222#*#*or*#*#3264#*#*.
Remember, not all Android devices support these secret codes due to variations in manufacturers and models.
Advanced Operations Using USSD Codes
