Where to see the serial number of the phone Xiaomi: all ways with a photo

Xiaomi’s smartphone serial number is a unique identifier that can be used to warranty service, unlock the bootloader, verify the originality of the device or restore data through the Mi Account. Without it, it is impossible to officially unlock the bootloader, activate hidden MIUI functions or prove that the phone is not fake when sold on Avito or Yule.

The problem is that the manufacturer has hidden this number in a not-so-obvious place. Unlike Samsung or iPhone, where it is duplicated on the case and in the menu, Xiaomi’s serial can “disappear” after resetting or flashing. In this article, 5 working ways to find it on any device of the brand (including Redmi, POCO and Black Shark), even if the phone does not turn on.

1. via phone settings (the fastest way)

If the smartphone is working and you have access to the system, the serial number can be found in 10 seconds, which is suitable for all models on MIUI 12-15 and Android 11-14, including the Xiaomi 13T Pro, Redmi Note 12 and POCO F5.

Open the Settings app (cog icon) and follow the path:

Settings → About the phone → All the characteristics

Scroll down to the Model Number block, below the Serial Number (or Serial Number in English firmware) if the line is empty or appears as unknown, so the number has been erased after being reset or firmware, move on to the next method.

Check if the custom firmware is installed.

Reboot the phone.

⚠️ Note: Some models (e.g. Xiaomi Mi) A1/A2 With pure Android) the path to the serial number is different: Settings → System system → The phone. → Serial number, and the number may be hidden behind Status. SIM-map SIM-maps and mobile networks.

2. Through a box, sticker under a battery or tray SIM-map

If the phone doesn't turn on or the serial number is dropped after you've run it, look for it on physical media.

• 📦 Phone box: on a barcode sticker (usually under film). S/N, Serial No. or IMEI/SN.
• 🔋 Under the battery: on some models (e.g. Redmi) 4X, Redmi Note 5 is on a sticker under the removable lid. Careful: if the battery is not removable, don't try to remove it, you risk damaging the plume.
• 📱 Tray SIM-Maps: on older models (Xiaomi Mi 5, Redmi) 3S) The serial number was engraved on a metal tray. It's not on the new devices.

Important: If you buy a phone with your hands, always check the serial number on the box and in the settings. The discrepancy means that the device is either fake or stitched with unofficial software (which makes it unwarranted).

3. through the engineering menu (for advanced users)

If the serial number doesn’t show up in the standard settings, it can be pulled out via an engineering menu (or Engineering Mode), which works even on custom firmware phones, but requires caution – wrong actions can cause the system to crash.

Enter the combination in the phone application:

##4636##

The Test menu will open. Go to the Device Information tab and scroll down, and the Serial Number bar may appear there. If it's not there, try the alternative code:

##284##

⚠️ Warning: Some firmware has blocked the engineering menu, so if nothing happens after you enter the code, then your version is the only one. MIUI Don't try to enter random combinations, it can lead to a hard brick).

4. via computer (ADB or Mi Flash Tool)

If the phone is turned on but the serial number doesn't show up in the settings, it can be pulled out using ADB (Android Debug Bridge), a method that requires debugging over USB and runs on Windows, macOS or Linux.

First, turn on the debugging:

1. Go to Settings → About Phone and 7 times click on the MIUI version to activate the Developer Mode.
2. Return to the main settings menu, open Additional → For developers and enable debugging via USB.
3. Connect the phone to the PC and confirm the debugging permission.

Then download ADB Tools, unpack the archive and type in the command line:

adb devices

If the device is determined, perform:

adb shell getprop ro.serialno

In response, you will receive a serial number in the format XXXXXXXXXXXXXX.

If ADB doesn’t help, try the official Mi Flash Tool:

1. Download the Mi Flash Tool and install it.
2. Connect the phone off in Fastboot mode (clip Volume Down + Power).
3. In the utility, press Refresh – the serial number will appear in the list of connected devices.

1. Install Xiaomi USB Drivers drivers.

2. Use another USB-cable (preferably original).

3. Switch the connection mode from Charging to File Transfer in the notification curtain.-->

5. via Mi Account (if the phone is tied)

If you forget the serial number but the phone is tied to the Mi Account, it can be restored via Xiaomi’s official website, which works even if the device is lost or stolen (but only if it was tied to an account before it went missing).

Go to the Mi Account page and follow the steps:

1. Sign in under your login.
2. Go to the Devices section.
3. Select the phone you want, and the serial number will be listed next to the model.

If the device is not listed, it means:

• 🔄 You didn't tie him to your account.
• 🚫 The phone was untied after resetting settings.
• 🛠️ The device is stitched with unofficial software (for example, LineageOS), which removed the binding.

⚠️ Note: If you buy Xiaomi with your hands, always check if it is untied from the previous Mi Account. → Xiaomi account – if someone else’s email is hanging there, the phone will be locked after a reset (Mi Cloud Lock).

6 If the phone is not turned on: alternative methods

When the smartphone doesn't respond to the power button, the serial number can only be found through hardware tags or specialized software.

• 🔌 Fastboot mode: Connect your phone to your PC, press Volume Down + Power for 10 seconds. If the device is identified in Windows Device Manager as Android Bootloader Interface, the serial number can be pulled through the Mi Flash Tool (see section 4).
• 🛠️ Service center: If the phone does not show signs of life, serial can be recognized only by IMEI (It usually stays in NV-This requires a programmer such as UFi Box or Medusa Pro, which is provided in service centers.
• 📄 Documents: Check the warranty card, check or sales contract - there may be a duplicate of the serial number.

If the phone is drowned, broken or burned, it is impossible to restore the serial number yourself, in which case you can only contact the authorized Xiaomi service center with proof of purchase (check or box).
