Xiaomi Authentication Sticker: Where to Look and How to Verify Your Device

When buying a Xiaomi smartphone or gadget, many users are faced with the question: how to distinguish the original device from a fake? One of the key signs of authenticity is the authentication sticker, a small sticker with a unique code that the manufacturer places on the case or packaging. However, finding it is not always easy: the location depends on the model, year of release and even the region of sale.

In this article, we will discuss in detail where to look for a sticker on different Xiaomi devices (smartphones, smartwatches, routers), how to check it correctly through official services, as well as warn against common errors that can cost you warranties or even money.

What is Xiaomi Authentication Sticker and Why You Need It

An authentication sticker (sometimes called an authenticity sticker) is a security element that Xiaomi puts on its devices to confirm their originality.

• 🔢 A unique 20-digit code (or QR- code) that can be checked on the manufacturer's website.
• 🏭 A serial number of a device that matches the data in the smartphone settings.
• 🛡️ Holographic elements (on new models) that are difficult to fake.
• 📦 Xiaomi logo and sometimes production date.

According to Xiaomi, up to 15% of devices sold in the secondary market (such as on Avito or AliExpress) are counterfeits.

• ✅ Confirm that the device has not been opened (e.g., to replace components).
• ✅ Check for the serial number to match the data in the system.
• ✅ Make sure the gadget hasn't been stolen or blocked by a previous owner.

⚠️ Warning: An authentication sticker is not the same as a warranty card or a IMEI sticker. It verifies the authenticity of the device, but does not replace warranty obligations. For example, if you delete the sticker, the warranty may remain, but authentication will become impossible.

On older models (before 2020), the sticker was often paper-based and easily detached, and on newer devices (such as the Xiaomi 13 Pro or Redmi Note 12), it was applied to the inside of the battery cap or under the removable panel, making it difficult to fake.

Where is the authentication sticker on Xiaomi smartphones

The location of the sticker depends on the design of the smartphone, and below we have updated data for the popular Xiaomi, Redmi and POCO series (information confirmed for 2026).

On some models (such as the Xiaomi 13 Ultra), the sticker can be hidden under a protective film on the back. To see it, gently tuck the film with a nail or a plastic card - the sticker is usually located in the upper left corner.

If you are buying a smartphone with your hands, be sure to check:

- Coincidence of the serial number on the sticker and in the settings (Settings → About the phone → General information)

Integrity of holographic elements (on new models)

- Presence of a duplicate sticker on the box (if it is saved)

- No traces of pasting (fake stickers often glue crooked)-->

⚠️ Warning: On non-removable battery devices (e.g., Xiaomi 12T), the sticker may be under a decorative panel that cannot be removed without damage. In this case, check the code through the official Xiaomi website by the serial number from the settings.

How to check the authentication sticker through the official website

Just checking the sticker doesn’t guarantee the authenticity of the device — it can be forged. To verify the originality, use the official verification service from Xiaomi:

1. Go to https://www.mi.com/global/verify (for global versions) or https://order.mi.com/site/product/auth (for Chinese models).
2. Enter the 20-character code from the sticker or scan the QR- code (if any).
3. Compare the data on the site with the information in the phone settings (Settings → About phone → Model and hardware version).

If the service gives an error "Authentication failed", this can mean:

• 🚫 The device is a fake.
• 🔧 The sticker is damaged or replaced.
• 🌍 The model is intended for another region (e.g., the Chinese version for Europe).

Newer models (e.g. Xiaomi 14) can use a digital verification tool via the Mi Verify app instead of the code, download it from Google Play or AppGallery, scan the QR- code from the sticker, and the system will automatically authenticate it.

💡

If the sticker is damaged but you are confident of the authenticity of the device, take a screenshot of the data from the official verification service and save it.

Where to look for a sticker on other Xiaomi devices (routers, watches, headphones)

Xiaomi is not only making smartphones, but also making smart devices, where the authentication sticker is also present.

On Mi Band devices (fitness bracelets), the sticker is usually absent - instead, the serial number on the box is used, which can be checked through the Mi Fitness application.

For Xiaomi routers, the sticker often contains not only the authentication code, but also the login data to the admin panel (login / password by default).

What to do if the authentication sticker is missing or damaged

The absence of a sticker is not always a sign of forgery. Here are the possible causes and solutions:

• 🔧 The device was repaired — in which case the sticker could be removed (e.g., when you replace the battery). Check repair history through Settings → About Phone → Device status.
• 📦 Box sticker: Some models (e.g., POCO X5) have the main sticker on the package only.
• 🔄 The device is refurbished – such gadgets are often sold without the original stickers, but with a new warranty.

If the sticker is damaged, but you are sure of the authenticity of the device:

1. Contact the official Xiaomi service center with a check about the purchase - they can confirm authenticity through the database.

⚠️ Warning: If you buy a device without a sticker at a price well below market, you may run into a “gray” import (e.g., the Chinese version for Europe) or a fake.

Can I Restore or Replace the Authentication Sticker?

Xiaomi does not officially provide a sticker recovery service, but there are several ways to solve the problem:

• 🛒 Buy a duplicate from official dealers – some stores (such as the Mi Store) sell spare stickers for popular models.

If you removed the sticker yourself (for example, when disassembling the phone), try:

1. Take a picture before it is removed (if it is not too late).
2. Write the code to a secure location (e.g., Mi Cloud notes).
3. When warranty repair, provide a check and data from the device settings.

Warning: Don't buy "original" stickers on AliExpress or Avito - 99% of them are fake. Fraudsters often sell stickers from other people's devices, which can lead to your gadget being blocked when checked.

💡

The only reliable way to verify authenticity without a sticker is to verify the serial number through Xiaomi’s official service. All other methods (including visual inspection) can be deceptive.

Frequent errors when checking authentication stickers

Many users make mistakes that lead to false conclusions about the authenticity of the device, and here are the most common:

• 🔍 The IMEI sticker with the authentication sticker is confusing - they're different! IMEI is needed for network identification, and the authenticity sticker confirms originality.
• 📱 Do not update the firmware before checking - on older versions of the software, the serial number may not appear correctly.
• 🌐 Using unofficial verification sites – scammers create copies of Xiaomi’s service to steal data.
• 🔧 Ignoring autopsy marks — if there are scratches from a screwdriver on the body, the device could be repaired or modified.

Another common mistake is box-only testing, and fraudsters often fake the packaging, but they can't accurately reproduce the sticker on the device itself. Always check the data from both sources!

If you doubt the authenticity, pay attention to the details:

• 🔋 On the original Xiaomi devices, the battery has a holographic sticker with a logo.
• 🔊 Mi Buds headphones in the original have a uniform sound on both speakers (on fakes, often the difference in volume).
• 📶 Xiaomi routers require authorization via Mi Home when first connected (fakes don’t).
