Whether you're preparing to sell your Oppo smartphone, request a new repair, or verify your second-hand purchase. One of the first steps is to get the serial number. Now, performing an Oppo serial number check is a straightforward process that takes only a few seconds. Depending on whether your phone is operational or turned off, there are three ways to locate the exact serial number of your Oppo phone, and here's how to do it.
Check Oppo Serial Number Using Phone App
The fastest way to find your Oppo phone's serial number and IMEI information is by using a secret Oppo code in your phone's dialler. This works universally across ColorOS and eliminates the need for digging through system menus.
- Launch the Phone app on your Oppo phone, open the keypad and dial *#06#.

- A screen will instantly pop up displaying your device's serial number (or EID).
Find Serial Number in Settings App
You can also use the Settings app to find the serial number, similar to how you check IMEI number on Oppo phones. The Settings app shows a bunch of hardware details, including your phone's serial number, and here's how to find it.
- Launch the Settings app on your Oppo phone and go to About device > Status.

- Scroll down this page to find a complete list of your hardware identifiers and locate the Serial number section to view your phone's serial number.

Check Oppo Serial Number from Original Retail Box
If your phone has a dead battery, a damaged display or simply will not turn on, you can still perform an Oppo serial number check without accessing the software.
- Grab the original packaging your phone came in and look at the bottom or sides of the box for a white barcode sticker that reads either 'Serial Number' or 'S/N'.

- When shipped new, Oppo phones come with a small sticker on the lower back. If you have not peeled this off yet, your serial number and IMEI can be found on it.
- If you retained the paperwork like the purchase invoice alongside the retail box, it should contain both the serial number and IMEI code right on the top or bottom.
And that's how you can check the serial number on Oppo phones. Once you know your phone's serial number, you can visit Oppo's official warranty portal to check the warranty on Oppo phones or find your Oppo phone's model number. All you need to do is enter the serial number in the empty text field and follow on-screen instructions. If you own a phone other than Oppo, here's how you check serial number on any Android phone.
