Where to watch the serial number of the Xiaomi TV: all the ways from the box to the service menu

Xiaomi’s serial number is a unique identifier that can be used in a variety of situations, from warranty registration to fault diagnosis or firmware repair. Without it, you can’t officially contact customer support, activate certain features or even sell the device on the secondary market.

In this article, we’ll look at all the ways you can find the serial number on Xiaomi Mi TV, Redmi Smart TV, Mi TV Q and other models, from the obvious (sticker on the case) to the hidden (service menu and command line). You’ll learn how to find SN even if the TV is not turned on, the remote control is lost or the box is missing. And for convenience, we’ve added step-by-step photo instructions, model matching table and answers to frequent questions.

1.Where to look for serial number on TV body

The most reliable and versatile way is to look at the TV itself, and the manufacturer puts the serial number on the factory sticker that's on the back, but the layout can vary depending on the model and year of production.

Here's where to look:

• 📺 Classical models (Mi) TV 4A/4C/4S): the sticker is located in the lower left or right corner of the back cover, next to the ports HDMI.
• 🔧 Models with metal body (Mi) TV 5 Pro, Mi TV 6): look for a sticker on the plastic insert near the power connectors.

If the sticker is erased or painted over, try to light it up with a flashlight at an angle - sometimes the numbers become visible. You can also gently wipe the surface with an alcohol wipe (do not use abrasives!).

💡

If the sticker is damaged, take a picture of it on the phone at maximum resolution, and then zoom in on the computer – often this helps to disassemble the characters.

Serial number in documents and on packaging

If you buy a new TV, the serial number is duplicated in several places:

Note: on Xiaomi boxes, the serial number can be denoted as S/N, Serial No. or simply SN. Sometimes it is hidden under a protective film - carefully tuck it into the nail.

3. How to find out the serial number through the menu of the TV

If the TV is turned on and you have a remote, the serial number can be found in the system settings, which works on all Xiaomi models with Android TV or PatchWall operating system (including Mi TV 4/5, Redmi Smart TV, etc.).

Instructions:

1. Turn on the TV and press the Settings button (⚙️) remote.
2. Go to the About TV section (About or System Information).
3. Select Status or Device Information.
4. Scroll down to the Serial Number block.

Some firmware may have different paths, such as Mi TV Q1, go to Settings → Device → TV → Model Information. If the menu is in Chinese, look for characters (about the program) or (device information).

4.Methods for a non-working TV

If the TV doesn’t turn on but you urgently need a serial number (for example, for warranty repairs), there are a few alternative methods:

A. Through the service menu (if there is an image but no OS boot)

On some Xiaomi models, you can call the engineering menu with a combination of buttons on the remote or the TV itself:

1. Press and hold Menu + Volume Down on the TV case (or Home + Back on the remote).
2. In the menu, select Device Info or Factory Menu.
3. Look for the SN or Serial strings.

B. Connecting to a computer (for advanced users)

If the TV is defined by the computer as USB-device (e.g. in mode) ADB), You can try to get a serial number through the command line:

adb shell getprop ro.serialno

This will require the enabled debugging mode (Settings → For developers → Debugging over USB) and installed ADB drivers.

5. How to verify the serial number for authenticity

Fake Xiaomi TVs (especially from unofficial sales channels) may be labeled fake. To make sure your serial number is original, use the official services:

Note that the Xiaomi official website must display the serial number along with the model TV and the activation date. If the system produces an Invalid Serial Number error, this may mean:

• ❌ The number is entered with a typo (check the symbols O and 0, I and 1).
• ❌ The device is not original or gray imported.
• ❌ The TV is not activated (it is necessary to connect to the Internet for the first time).

💡

If the serial number does not pass the check, but the TV is purchased in the official store, contact the seller - it is possible that there is an error in the database.

6. Frequent mistakes and how to avoid them

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

Problem 1: The sticker is erased or missing

⚠️ Warning: If the serial number sticker is damaged and the TV is still under warranty, do not try to restore it yourself - this may void the warranty.

Problem 2: Serial number is not displayed in the menu

This may be due to:

• 🔄 Outdated firmware (update TV via Settings) → Update of the PO).
• 🛠️ Custom firmware (try resetting to factory settings).
• 🔌 Internet access (some models require a connection to display) SN).

Problem 3: The number is not suitable for registration of the guarantee

Xiaomi TV serial numbers for the Russian market start with the letters RU or RCN, for the European - with EU. If your SN starts differently, the device may be designed for another region.

7. Alternative identifiers: IMEI, MAC-address

If the serial number cannot be found, other unique identifiers can be used for some operations (such as Wi-Fi connection or diagnostics):

• 📡 MAC-Address: located in Settings → Network → Connection status. Example: 00:1A:2B:3C:4D:5E.
• 📱 IMEI: It's only a TV with a module. 4G/5G (Like Mi. TV LUX). You can see the settings. → On TV. → Status. SIM.
• 🔑 Android ID: It's generated by the system, but it's not permanent. ADB:

adb shell settings get secure android_id

However, these identifiers do not replace the serial number for warranty service or registration with the Mi Account.
