How to find the Xiaomi Redmi serial number: all methods (including hidden ones)

Why Xiaomi Redmi Serial Number Is More Important Than You Think

Your Xiaomi Redmi’s S/N serial number is not just a set of numbers on the box; it’s a unique device passport that comes in handy in the most unexpected situations, such as when you go to a warranty repair service center without it, you won’t be served without it, and if the phone is stolen or lost, the serial number will help you lock it through Mi Account or even track it (provided the device was tied to your account).

But there are less obvious cases: a serial number is required to unlock a bootloader unlock if you decide to flash your smartphone custom firmware. Some banks request an S/N when applying for a loan against technology. Even when selling a phone on Avito or Yula, customers often ask for a serial phone to confirm the originality of the device, which is why every Redmi owner should know where to find it, from the budget Redmi A2 to the flagship Redmi K70 Pro.

Method 1: through phone settings (fastest)

If your Xiaomi Redmi is turned on and running, it will take no more than 10 seconds to do this, and the serial number is stored in system data, and is available even without root permission.

Open the Settings app (the gear icon on the home screen).
Scroll down and select About Phone (or About Device on newer versions of MIUI).
Slip on the item All characteristics (in some models it is called General information).
Find the serial number (S/N) line.

On new smartphones (like the Redmi Note 13 Pro+), the path may be slightly different: Settings → Phone → Device Information → Status. If you don’t find it, search by settings (the magnifier in the upper right corner) and type “serial.”

💡

If the serial number is displayed as unknown or 000000000, it could mean that the phone’s firmware has been changed or the smartphone is unoriginal (replica).

Note: on some models (e.g. Redmi) 9A or Redmi 10C) The serial number can be duplicated in the Status section. SIM-maps (Settings) → SIM-maps and mobile networks → Status. SIM-There's a name for it sometimes called IMEI/SN.

Method 2: through the box and documents (if the phone is not turned on)

If the smartphone doesn't respond to charging or the screen is broken, you can find the serial number on the original package.

📦 A sticker on the end of the box (usually on the right or bottom). S/N or Serial No. next to the barcode.
📄 Warranty card (if saved) The serial number is indicated at the top along with IMEI.
🛒 Check or invoice from the store. In some networks (for example, the Messenger or M. Video), the serial number is broken into the database on the check.

What to do if the sticker on the box is erased?

If the numbers on the box don't read, try lighting the sticker with a flashlight at an angle -- sometimes it helps to see the remnants of the paint, you can also take a high-resolution picture of it and zoom in on your computer. If it doesn't work, go to the store where you bought the phone, they may have a copy of the document with the serial in the database.

Important: on fake Xiaomi models (especially popular models like the Redmi Note 12), the serial number on the box often doesn't match the real one. To check the originality, compare the S/N from the box and from the phone settings. If they're different, you've got a replica.

Method 3: via battery (for collapsible models)

If your Redmi is from older models with a removable back cover (such as the Redmi 4X, Redmi 5A or Redmi 6), the serial number can be found under the battery.

Turn off the phone and remove it. SIM-map

Remove the back cover (a plastic shoulder blade or mediator will be required)

Take the battery off (don’t pull the wires!)

Find the sticker with the serial number on the board under the battery-->

On new models (starting with the Redmi Note 8), the battery is non-removable, and it is not recommended to disassemble the phone without experience - you can damage the plumes.

⚠️ Warning: If you've never taken a smartphone apart, don't try to remove the lid yourself. On adhesive-mounted models (such as the Redmi Note 11), there's a high risk of damaging the tightness of the case, which will lead to moisture.

On some devices (e.g. Redmi) K40) serial number is duplicated on a sticker under the slot for SIM-To see it, you just need to take out the card tray and light it with a flashlight.

Method 4: via ADB (for advanced users)

If the phone turns on but the serial number doesn't show up in the settings (like after a reset or firmware), it can be pulled out via Android Debug Bridge (ADB).

Here's what we need to do:

Download and install ADB Tools on your computer.
Turn on the developer mode on the phone (go to Settings → About phone and 7 times tap on the MIUI version).
Activate Debugging by USB in the Developer Menu.
Connect your phone to your PC and type in the command line: adb shell getprop ro.serialno

If the team doesn’t work, try an alternative:

adb shell settings get secure android_id

It will return a unique device identifier that is sometimes used in place of a serial number.

⚠️ Note: Do not enter unknowns. ADB-commands from the Internet — this can cause a phone to reset or damage to the firmware. Use only verified sources.

Method 5: Mi Account (if your phone is lost)

If your Xiaomi Redmi is lost or stolen, you can try to recover the serial number through the linked Mi Account.

Go to the Mi Account website and log in.
Go to the Devices section.
Select your Redmi from the list. If your phone is connected to the Internet, it will display its IMEI and serial number.

If the device is disabled, the data may not show up, in which case, try to contact Xiaomi support via the feedback form, specifying:

📱 Model phone
🔢 IMEI (if known)
📅 Purchase date and check (if retained)

The serial number in Mi Account is only updated when the phone is connected to the Internet, and if the device is turned off for more than 30 days, the data can be deleted from the system.

What to do if the serial number is erased or not read?

If all of these things don't work, then there are radical measures.

Situation	Decision	Risks.
The serialist was wiped off the box and the phone.	Contact the Xiaomi service center with a check	They can refuse without a warranty card.
The phone doesn't turn on, there's no box.	Use IMEI to restore S/N through support	IMEI must be original (not cloned)
Post-firmware device	Restore the stock firmware through the Mi Flash Tool	Data loss, possible brick
Fake Xiaomi (remark)	Try to find S/N through the engineering menu (#4636##)	On replicas, serials are often fake

If you bought a phone with your hands and can't find the serial number, check it for originality through Mi Verify. This will require IMEI (you can find it using the code *#06#).

💡

Never buy a Xiaomi Redmi without checking the serial number and IMEI. Even if the seller shows a working phone, it can be cloned or stolen.
