In this article, we will discuss in detail what types of identifiers exist on Xiaomi phones (IMEI, serial, MIUI ID And others, where to find them and how to use them, and you'll learn about hidden codes, system menus, and even how to recover lost data, and you'll focus on the nuances that are often overlooked in standard instructions, like how to check. ID on a locked phone or what to do if the identifiers do not match the data on the box.

What are the identifiers of Xiaomi phones and why do they need them?

Xiaomi smartphones, like any other device, have several types of unique identifiers, each of which performs a different function and may be required in different situations:

• 📱 IMEI (International Mobile Equipment Identity is the primary identifier for communication networks, needed to unlock the operator, verify originality and recover from theft.
• 🔢 Serial number (S/N) — Unique device code used for warranty service and authentication.
• 🔑 MIUI ID — internal firmware identifier may be required to debug or modify the system.
• 🆔 Android ID — Virtual ID associated with a Google account (sometimes required to recover data).
• 📦 MAC-addresses – identifiers of network modules (Wi-Fi, Bluetooth), necessary for setting up connections.

For example, IMEI It consists of 15 digits and includes information about the model, country of manufacture and serial number of the device, which is often asked to provide when contacting in support or to unlock the bootloader through the official Xiaomi website. IMEI and is usually listed on the box and in system settings.

It is important to understand that some identifiers (e.g. MIUI ID) may change after resetting or flashing, whereas IMEI and serial number remain unchanged throughout the life of the device.

Method 1: Verify IMEI and serial number through phone settings

The easiest and safest way to find out the basic identifiers is through the system menu, which works on all Xiaomi models, including Redmi, POCO and Black Shark, regardless of the MIUI version.

Instructions:

1. Open the Settings app (cog icon).
2. Go to About Phone (sometimes called About Device or Phone Information).
3. Find the item All characteristics or General information.
4. Scroll down to the block. IMEI — There will be one or two numbers (for devices with two numbers). SIM-map).
5. The serial number (S/N) is usually located next to or in a separate location.

On some models (such as Xiaomi 13 Pro or Redmi Note 12), the path may be slightly different:

Settings → About the phone → Device Information → Status

If you have a dual-sim phone, you’ll see two IMEIs, IMEI 1 and IMEI 2, both of which are important, especially if you’re planning to unlock a bootloader or restore access to your account.

⚠️ Note: If the settings are displayed IMEI If you look like 000000000000000000 or Invalid, it means that the ID has been reset or damaged, in which case the phone will not be able to connect to mobile networks, and you will need to restore it through a service center.

Method 2: Use of the USSD-codes IMEI

If you do not have access to settings (for example, the phone is locked), you can find out IMEI specially USSD-This method works even on the screen off if the device is on and there is access to the keyboard of the set.

Enter the following code in the Phone application:

After dialing, a window with one or two numbers will immediately appear on the screen. IMEI (depending on the quantity SIM-This method is universal and works on all smartphones, including Xiaomi, Samsung, iPhone and other brands.

Advantages of the method:

• ⚡ It works without unlocking the phone.
• 🔄 It does not require an internet connection.
• 📱 Suitable for devices with damaged screen (if the sensor is working).

Limitations:

• 🚫 Does not show the serial number or MIUI ID.
• 🔒 On some operators USSD-codes may be blocked (rarely, but occur).

💡

If your phone doesn’t respond to the *#06# code, try typing it in emergency call mode (even when the screen is locked on some models).

Method 3: View IDs on the box and under the battery

If the phone doesn't turn on or you don't have access to it, you can find the IMEI and serial number on the original packaging, and the manufacturer puts that data in stickers or printed text.

Where to look:

• 📦 On the box - usually on the side or underside, next to the barcode.
• 🔋 Under the battery – on some models (for example, Redmi) 4X or Mi A1) IMEI indicated on the sticker under the removable cover.
• 📄 In the warranty card - if it is retained.

Example of location on the box:

It's important to compare the data in the box to the data in the phone settings, and if it doesn't match, it could mean:

• 🔄 The phone was repaired with a replacement motherboard (IMEI might have changed).
• 🚨 Device unoriginal (forgery or "gray" import).

Method 4: How to find MIUI ID and other hidden identifiers

MIUI ID is an internal firmware identifier that may be required to debug, modify a system, or recover from a crash. Unlike IMEI, it is not standardized and can change after a setup is reset.

To get to know him:

1. Activate Developer Mode: Settings → About Phone → MIUI Version (click 7 times)
2. Return to the main Settings menu and open Additional → for developers.

2. Open the command line and type in: adb shell settings get secure android_id
3. For MIUI ID, use: adb shell getprop ro.miui.ui.version.code

Other useful commands for obtaining identifiers:

adb shell getprop ro.serialno # Serial number


adb shell getprop ro.boot.serialno # Alternative serial number




adb shell ip route # MAC- Wi-Fi address

Method 5: Verification of IDs via computer (using Fastboot)

If the phone is not turned on or locked but is responsive to a PC connection, you can find out the IMEI and serial number through Fastboot mode.This method requires installed drivers and the Fastboot tool (part of the Android SDK).

Step-by-step:

1. Turn off the phone.
2. Press the buttons Volume down + Power before the Fastboot logo appears.
3. Connect your phone to your computer via USB.
4. Open the command line and type: fastboot devices If the device is determined, you will see its serial number.
5. For IMEI, use fastboot getvar imei or fastboot oem device-info.

Example of conclusion:

(bootloader)    imei: 861234567890123


(bootloader)    imei2: 861234567890456




(bootloader)    serialno: a1b2c3d4e5f6

This method is particularly useful if:

• 🔄 The phone does not load (hangs on the logo or bootloop).
• 🔒 The screen is locked and you don’t remember the password.
• 📱 You need to check the IDs before the firmware.

⚠️ Note: Fastboot oem commands can be blocked on some Xiaomi models (especially those with a locked bootloader). FAILED (Remote: Unknown command: Unlock the bootloader through the official Xiaomi website.

Frequent problems and their solutions

When working with Xiaomi IDs, users often encounter common errors, and let’s look at the most common ones and how to fix them.

Problem 1: The IMEI is displayed as “Unavailable” or “0000...”

Possible causes:

• 🔧 Nvram file damage (often after incorrect firmware).
• 🔄 Hardware failure of the communication module.
• 📱 The phone was recovered after a complete loss of data.

Decision:

• Flash your phone with the official firmware through the Mi Flash Tool.
• Restore the IMEI with the Engineering Menu (code ##4636## → Phone Information).
• Contact the service center for reflashing nvram.

Problem 2: The serial number on the box and the phone are not the same.

This is a warning sign that could mean:

• 📦 Phone and box from different devices (for example, when buying from hand).
• 🔧 The device was repaired with the replacement of the motherboard.
• 🚨 This is a fake (especially relevant for popular models like the Redmi Note 10 or the Redmi Note). POCO X3).

Decision:

• Check out the IMEI through the official Xiaomi service.
• Compare the look of the phone with the original photos on the manufacturer’s website.
• Check the operation of all sensors and modules (camera, GPS, NFC) – they often work incorrectly on fakes.

Problem 3: You can't get a MIUI ID.

If you don’t see MIUI ID in the developer settings, try:

• Update the firmware to the latest version.
• Use alternative diagnostic applications (e.g., CPU-Z).
• Check if the item is hidden in your version of MIUI (some firmware calls it Unique Device ID).

💡

If you plan to unlock the bootloader or restore access to the Mi Account, always check the IMEI and serial number against the data on the box.Differences can result in a denial of unlock or loss of warranty.
