USSD and dialer codes by brand

About this tool

A searchable list of Android dialer (USSD/MMI) codes. Filter by brand or search by keyword, then tap a code to copy it. Each entry is tagged by risk.

Tags: info safe to view, caution engineering menus you can misconfigure, destructive wipes your device.

What are secret codes?

These are USSD and MMI codes: short sequences of *, # and digits you type into the phone dialer. The phone (or network) recognizes them and opens a hidden menu or runs an action instead of placing a call.

*#06# (show IMEI) is the most universal. Many others are brand- or model-specific and may do nothing, or something drastic, on the wrong device.

Tips

  • Codes tagged destructive can factory-reset with no confirmation. Don't try them out of curiosity.
  • Many codes are blocked on newer Android versions for security.
  • Engineering menus can change radio/network settings, so note the original values before you touch anything.
  • Codes vary by model and region; a code working on one phone may do nothing on another.

About the Secret Codes Database

Android phones hide a layer of USSD and MMI codes: short sequences you type into the dialer that the phone or network intercepts to open hidden menus or run an action instead of placing a call. They're invaluable for diagnostics and repair, but a few can wipe a device instantly. This database collects codes across major brands, lets you filter by manufacturer or search by keyword, and tags every entry with a clear risk level so you know what you're about to run.

Reading the danger tags

  • info: safe to view; shows information or opens a read-only menu.
  • caution: engineering/diagnostic menus you can misconfigure; note the original values before changing anything.
  • destructive: can factory-reset or wipe your device, sometimes with no confirmation prompt. Don't run these to "see what happens".

How to use a code

Open the phone dialer and type the code exactly, including every * and #. Universal codes like *#06# (show IMEI) work everywhere; most others are brand- or model-specific. On modern Android many codes are blocked for security, so a code doing nothing is normal and harmless.

Frequently asked questions

What are secret/USSD codes?

Short dialer sequences of *, # and digits that trigger a hidden menu or action. They're a built-in feature of the phone and network, not a hack.

Are they dangerous?

Most are safe info or test menus, but codes tagged destructive can factory-reset with no warning. Only run a destructive code if you intend the wipe and have backed up.

Why doesn't a code work for me?

Codes depend on brand, model, region and Android version. Newer phones block many of them. A code that worked on an older device may simply be disabled on yours.

Is *#06# safe?

Yes. It only displays your IMEI number(s) and works on virtually every phone, and it changes nothing.
