List of All OnePlus Secret Codes and Service Codes (2023)

This post will provide a comprehensive list of all the OnePlus secret and service codes. Although you may primarily use the Phone Dialer for making calls, it has additional functionalities beyond that. Your OnePlus device contains numerous hidden codes that can be activated or enabled directly from the dialer. Some codes display hardware and software information, while others can reset your device. Additionally, you can access an Engineer Mode, Test Mode, and hidden menus through the dialer.

There are many codes specific to carriers like T-Mobile and AT&T. However, trying out all of them is not recommended just because they have some benefits. You should read their descriptions carefully and only use the ones you need. Additionally, some codes only work on certain OnePlus devices and may not work on others. It is important to confirm if the code applies to your specific device before trying it out.

Also, some of these codes might be region-specific as well. Unfortunately, the only way to check them is to try them out if they work out as intended, well and good, otherwise, move over to the next one. As far as the activation of these codes goes, it might work on either of the two days. While some get executed automatically after entering the last digit, for others, you might have to hit the Call button. With that said, here are all the OnePlus Service Codes and Secret Codes that you should check out. Follow along.

Check IMEI Number

IMEI or International Mobile Equipment Identity is a unique 15 digit number associated with every device. This is among the most important piece of information about your device and could come in handy in a wide array of sections. For example, if you have lost your device but have the IMEI number with yourself, you could interact with the concerned authority and blocked your device right away.

Likewise, it might also come in handy when you are about to exchange your device. There are two ways through which you could check this number, the first one is via the device’s Settings menu but that requires quite a lot of effort. A much easier route involves using the below OnePlus smartphone service and secret code:

*#06# _____ Show IMEI & MEID 
*#66# _____ Show & Encrypt IMEI & MEID

Engineering Mode

The Engineering Mode on your OnePlus devices is a diagnostic tool menu that could be used for checking the proper functioning of various software components. Likewise, this menu is also used for after-sales service support or for troubleshooting various issues. To access this menu, you will have to enter the below-mentioned command:

*#36446337#

Once you do so, you will be taken to the Factory Mode with tons of options. These include the Network Set, Protocol Test Switch, Charging Settings, Qualcomm, RGB Sensor Test, Touch key test, among others.

Reset Device

You could also reset your device just by entering a few OnePlus smartphone service and secret codes on your dialer. If the device is not working as expected, or you wish to perform a hard reset for any of the other concerned reasons, you could head over to Settings and do the same. Or a shorter route involves using the dialer and using the below-mentioned codes.

Furthermore, there are also variations to these codes. While some lets you only delete data, others allow you to remove Google Account while the third one completely wipes the firmware and then reinstall it. In this regard, here are all these codes. Proceed ahead with caution, you have been warned!

*#8778# ______________ Resets device, can be canceled 
*#*#7780#*#* _________ Erases Google account, third-party apps, & all associated data. Can be canceled 
*#*#947322243#*#* ____ Instant Data Wipe 
*2767*3855# __________ Completely wipes device & reinstalls firmware

Call Tweaks

OnePlus also beholds a ton of service and secret codes related to calling.
