How to find out the ID on Xiaomi phone: IMEI, serial number and MIUI ID

Each Xiaomi smartphone has unique identifiers that you might need to unlock a bootloader, restore access to your Mi Account, verify the originality of the device, or contact a service center. But where exactly do you look for this data? Depending on the situation, you may need an IMEI (International Mobile Equipment Identifier), a serial number (S/N), or a MIUI ID, an internal firmware code.

In this article, we will discuss all the current ways of obtaining ID on Xiaomi phones, Redmi phones, POCO And Black Shark, from the standard settings menu to the hidden engineering commands, and we'll focus on the nuances for dual-use devices. SIM-And if you're not sure what kind of ID you want, you'll find at the end of this article, you'll find a little bit of a copy of the card. FAQ explainably.

1.How to find out IMEI on Xiaomi through phone settings

The easiest and most versatile way is to use the standard Settings menu.It works on all models, including the Xiaomi 13T Pro, Redmi Note 12 and POCO F5, regardless of the MIUI version (even on MIUI 14 and later).

Instructions:

• 📱 Open the Settings app (cog icon on the home screen).
• 🔍 Scroll down and select About Phone (on some firmware – About Device).
• 📋 Tap on item All characteristics (or General information).
• 🔢 Find a line. IMEI — One or two numbers will be listed here (for devices with two support). SIM-map).

If you have duality SIM-model (e.g. Xiaomi) 12S Ultra, you'll see two. IMEI: IMEI 1 (first) SIM) and IMEI 2 (second) SIM). Both numbers are useful for unlocking the operator or checking through services like IMEI.info.

⚠️ Note: Some firmware (especially custom) may have a section about the phone hidden, in which case use alternative methods from the following sections.

2.Recognize the IMEI and serial number through code *#06#

Universal. USSD-*#06# is available on all Xiaomi smartphones, including older models like Redmi 4X And new flagships like Xiaomi 14, which doesn't require an internet connection and takes less than 5 seconds.

How to use:

1. Open the phone (calling) application.
2. Enter *#06# (as if you were dialing a number).
3. Press the call button (green tube).
4. A window will appear on the screen with IMEI, serial number (S/N) and other service information.

The advantage of this method is that it works even if the phone is not activated (for example, after purchase) or locked with a pattern lock. However, on some firmware (for example, MIUI Global Stable for the European region), the code may not display the serial number - only IMEI.

3.Where to find the serial number and IMEI on the box and under the battery

If the phone is not switched on or locked, the identifiers can be physically recognized by being listed on the box and under the back cover of the device, a method that is relevant for owners of Xiaomi with a non-removable battery (for example, the Redmi Note 11 Pro+) and older models with a removable battery (for example, the Redmi 3S).

Where to look:

• 📦 On the box: IMEI and the serial number is indicated on a barcode sticker (usually at the bottom or side of the package).
• 🔋 Under the battery: on older models (until 2018) sticker with IMEI It's under the battery. It's on new devices, POCO X5 Pro) – under the back cover, but it is difficult to reach it without special tools.
• 📄 In the warranty card: if saved, there are duplicated all identifiers.

Some models (such as Black Shark 5 Pro) IMEI may be indicated SIM-Check it in bright light. If the sticker is erased, try to restore the number through the engineering menu.

⚠️ Attention: If IMEI The box and the phone don't match, which may indicate a motherboard swap or a gray device.

4. How to find out MIUI ID and other hidden identifiers

MIUI ID is a unique firmware code that can be used to debug, unlock the bootloader or restore it via Fastboot. It can't be found in standard settings, but there are two reliable ways to do it:

Method 1: Through the Engineering Menu (CIT)

• 📱 Open the phone app and type ##4636##.
• 🔧 In the menu that appears, select Phone Information.
• 📝 Scroll down to the block. MIUI Version - there will be a line here MIUI ID (for example, V12.5.3.0.RKHCNXM).

Method 2: ADB (for advanced users)

If the engineering menu is blocked, use ADB:

adb shell getprop ro.miui.ui.version.code

This command will return the current MIUI ID, and it requires Platform Tools and enabled USB Debugging.

5. Verification of ID through computer (Fastboot and Mi Flash Tool)

If the phone is not turned on or locked, the identifiers can be retrieved via Fastboot or Mi Flash Tool, USB-Cable and basic knowledge of working with the command line.

Instructions for Fastboot:

1. Turn off the phone and press Volume Down + Power to enter Fastboot mode.
2. Connect the device to the computer.
3. Open the Command Prompt in the Platform Tools folder and type: fastboot getvar all
4. In the conclusion, find the lines: serialno - serial number. imei - IMEI (may be several lines for dual SIM).

For the Mi Flash Tool:

Download the utility from the official Xiaomi website, connect the phone in Fastboot mode and press Refresh. the program automatically determines the serial number and other identifiers.

⚠️ Note: If you output fastboot getvar all instead of IMEI The id is displayed as zeros (imei: 0), meaning that the identifier is erased (for example, after a failed firmware) and can only be restored through a service center or specialized services like IMEI Server (risky!).

💡

If you often work with Fastboot, save the output of the command fastboot getvar all to a text file. This will help you quickly find identifiers when you access the service or unlock the bootloader.

6. Third-party applications for ID verification

If standard methods don't work (for example, on custom firmware), you can use third-party utilities, and we tested them on Xiaomi, Redmi and POCO - the best options:

• 📲 CPU-Z (show IMEI, serial number and processor information).
• 🔍 AIDA64 (Detailed information about the device, including MIUI ID Android → System system).
• 🛠️ DevCheck (convenient interface with data export to file).

Warning: Avoid obscure applications that request unnecessary permissions (such as accessing SMS or contacts).Some utilities (such as IMEI Changer) can irreversibly damage system files if used to change identifiers.

💡

Applications like CPU-Z or AIDA64 are secure, but they don’t guarantee 100% accuracy. For formal procedures (unlock, warranty), use data from settings or physical labeling.

7. Frequent mistakes and how to avoid them

When searching for IDs, users often face typical problems, and here are the most common ones and ways to solve them:

• 🔄 IMEI not displayed in the settings → Check if the Phone section is hidden in custom firmware. Try the code *#06#.
• 🔋 Phone's off. → Use data from the box or Fastboot (section 5).
• 🔒 Loader locked. → IMEI You can find out through fastboot getvar all, but you will need official permission from Xiaomi to unlock it.
• 📱 Two. IMEI, but single-sim phone → This is normal for some models (e.g. Xiaomi). 11T Pro where the second slot is reserved under eSIM.

If you suspect that the IMEI is tampered with (e.g., consists of single digits or repeated combinations), check it through the IMEI.info service.
