How to view Xiaomi device ID: from IMEI to serial number

Every Xiaomi owner will have to find out the unique IDs of their device, which may be needed to unlock the bootloader, restore access to the Mi Account, verify the originality of the gadget, or even for warranty maintenance. But where exactly to look for these cherished numbers? Spoiler: there are at least three types, and each is responsible for its function.

In this article, we'll look at all the current ways to get IMEI, serial number (SN) and unique device ID, from standard MIUI/HyperOS menus to hidden engineering commands, and why some methods stop working after resetting and how to pull out IDs if the smartphone doesn't turn on.

1. Standard Ways: Where Xiaomi Hide ID in Settings

If your Redmi, POCO, or Xiaomi is working properly, you can start looking for IDs from the built-in menus, and the manufacturer has provided several ways to access this information, which is enough for 90% of tasks.

The most obvious route is through Settings → About the phone. Here in the General Information block you will find:

• 📱 Device model (e.g. Redmi Note 12 Pro)+ 5G)
• 🔢 IMEI (one or two for devices with two SIM-map)
• 🆔 Serial number (SN) — unique 11-14 symbolism

On HyperOS (new firmware for flagships in 2026) the path has changed a little: Settings → The phone. → All the features. And on the Xiaomi Pad, the information is hidden deeper in Settings. → System system → Note that if you have an eSIM device, next to the IMEI may display an inscription EID — It's an embedded ID. SIM-map.

💡

On some models (e.g. Xiaomi) 13T Pro) the serial number is duplicated on the sticker under the slot SIM-This is convenient if the phone is not turning on, but the case is not damaged.

2. Codes for the engineering menu: quick access to hidden data

When standard settings do not help (for example, after a reset or if the About Phone menu is not available), service services come to the rescue. USSD-They work on all Xiaomi devices, regardless of version. MIUI or hyperos.

Open the Phone app and enter the following combinations:

• 📞 *#6# - will show IMEI (One or two for Dual-SIM)
• 🔧 ##4636## - opens the Testing menu, where you can see the phone information section IMEI and serial number
• 🔍 ##225## - Alternative way to view calendar information (sometimes contains a calendar) SN)

An important nuance: on some models (for example, POCO F5), after entering the code #06#, IMEI may not appear immediately - you have to click on the status bar at the top of the screen.

3. Physical tags: where to look for IDs on case and packaging

If the smartphone is not turned on or locked, the identifiers can be found on physical tags, and the manufacturer duplicates the key information in three places:

1. Sticker under the lid SIM-maps contain IMEI, The serial number and model are relevant to most Redmis and POCO.
2. Box of the device - on the label with a barcode are indicated IMEI and SN (sometimes QR-code).
3. Battery – On some older models (e.g. Redmi 4X), the serial number is directly applied to the battery.

Beware of counterfeits: on counterfeit devices, IMEI can be forged (for example, consist of one zero or repeat popular combinations), and you can check the originality on IMEI.info - enter the code and compare the data with the ones listed on the box.

4. ADB-commands: how to pull out ID computer

If the phone is on but the settings are restricted (e.g., because the screen is locked), you can connect to it via ADB (Android Debug Bridge), which requires pre-activation of USB Debugging in the Developer Menu.

Here's the step-by-step instruction:

1. Connect your smartphone to your PC through USB-cable.
2. Open the command line (Windows) or the terminal (macOS/Linux).
3. Enter the command to check the connection: adb devices must appear serial number of the device.
4. Get IMEI: Adb shell service call iphonesubinfo 3
5. Get the serial number: adb shell getprop ro.serialno

On HyperOS devices, the command for IMEI may not work – instead, use:

adb shell dumpsys iphonesubinfo

In the output, look for the Device ID strings (this is IMEI).

5. Special Applications: When Standard Methods Fail

If none of these methods worked (for example, after a complete reset or damage to the firmware), third-party utilities will come to the rescue, they can read identifiers even from locked or “bricks” (devices that do not pass the boot).

Top.-3 tested applications:

• 🛠️ MIUI Hidden Settings – Shows advanced information about the device, including hidden devices ID.
• 🔍 Device ID by EVOZI — lead out IMEI, SN, Android ID other technical data.
• 📱 AIDA64 — professional iron analyzer, where in the "System" section there is a tab "IMEI".

Warning: some annexes (e.g, IMEI Changer) promise to “restore” or “modify" IMEI, But using them can lead to a loss of warranty or even a network lock. IMEI — This violates the laws of many countries.

💡

ID-reading applications only require super-user (root) rights in the case of corrupted firmware, and they run without additional permissions on standard devices.

6. Black screen or brick: how to find the ID of a broken device

Things get more complicated if the smartphone doesn't turn on at all, neither in normal mode nor in Fastboot, and a combination of physical tags and specialized software will help.

Algorithm of action:

1. Check the sticker under SIM-card and box - if IMEI It can be used to unlock through Mi Account.
2. If the device is detected by the computer in Qualcomm 9008 mode (checked in Device Manager), use the Mi Flash Tool utility - it will show the serial number when you connect.
3. For devices on the MediaTek processor SP Flash Tool is suitable - in the connection logs there will be a string with Serial Number.

⚠️ Note: If you see a message Unauthorized device when you connect to the Mi Flash Tool, it means that the Mi Account is not authorized to firmware this device.

The last chance is to contact Xiaomi’s service center with a purchase check, and using the serial number from the database, they will be able to restore access to the device (if it is not blacklisted due to theft or fraud).

7. Frequent mistakes and how to avoid them

Even experienced users sometimes have trouble finding an ID, and here are the most common pitfalls and ways to get around them:

• 🔄 IMEI slipped off → This means that the firmware was installed incorrectly (for example, via Fastboot without saving it). NVRAM). Solution - restore backup of the modem partition.
• 🔒 Serial number is not accepted on the Xiaomi website → Check the symbol register (SN It's capital-sensitive, and it's not space-sensitive, sometimes it's 0 instead of O).
• 📵 Code *#06# is not working → For some operators (for example, Tele2) USSD-Requests are blocked. Try another one. SIM Or use the engineering menu.

⚠️ Note: If you bought the device from hand and found that IMEI The phone and the box are not the same, and there are two options: either the seller has replaced the motherboard (which cancels the warranty), or it is a fake. In both cases, contact the seller for a refund - such devices can be blocked by the operator at any time.
