Your Android phone has a set of hidden dial codes built right into the dialer app. Punch one in and you can pull up your device’s IMEI, check network certification details, run hardware diagnostics, or manage how calls get forwarded, all without downloading a single app.
Working Android Secret Codes
Every code below still runs on current Android software, though a few depend on your carrier supporting call forwarding and call waiting features.

How to redeem codes in Android
You don’t need any special menu or app to run these. Everything happens straight from the phone app you already use to make calls.
*#06#, *#07#, and the ones with double asterisks and pound signs run automatically the moment you finish typing them. Codes such as *#67#, *#61#, #31#, *31#, *43#, and #43# need you to tap the green Call button before anything happens.You’ll know a code worked when a pop-up screen or new menu appears on top of the dialer, showing the requested information or confirming the setting change. If nothing happens after you tap Call, your carrier likely doesn’t support that particular feature.

How to get more Android secret codes
These dial codes come from the underlying network and telephony standards your phone uses, not from a single app or developer pushing out updates. Because of that, new codes don’t show up on a regular schedule the way in-game rewards do. Your safest bet is checking your device manufacturer’s official support pages, since some brands add their own extra service codes on top of the standard set, and confirming any code against your carrier’s documentation before relying on it for something important like call forwarding.
Do these codes cost anything to use?
No. Every code listed here is a free, built-in feature of the Android dialer and your phone’s network connection. You’re not charged for entering them.
Why didn’t a code work on my phone?
A code can fail to run if you mistype an asterisk or pound sign, if your carrier doesn’t support that specific network feature, or if the software build on your phone has removed the underlying service menu, as happened with the expired code above.
