Introduction: Why you need to authenticate Xiaomi devices
One in three smartphones in the world today is a fake, and Xiaomi’s brand is no exception. According to the company, up to 15 percent of devices sold under its brand name in the secondary market are counterfeit. The authentication code is a unique digital “passport” of a product that allows you to distinguish the original from a copy before you buy it.
In this article, we will examine all the official ways to authenticate Xiaomi equipment, from Redmi and POCO smartphones to Mi Band smartwatches and routers, you will learn what codes are (IMEI, SN, verification code from the sticker), how to decrypt them through Xiaomi services and what to do if the data do not match, and also reveal the scheme of fraudsters who forge even official verification certificates.
Xiaomi authentication code types: how they differ
Xiaomi devices have three main types of identifiers that are used for authentication, often confused, but each has its own purpose:
- 🔢 IMEI — Unique 15-digit code of a mobile device (smartphones, tablets) tied to a modem and does not change when resetting settings.
- 🆔 Serial number (SN) — identifier of a particular instance of equipment (from smartphones to routers) The format depends on the model (for example, the Redmi Note 12 has 14 characters, the Mi Band 7 has 12 characters).
- 🏷️ The check code from the sticker is a 20-digit combination under the protective layer on the box. Used for a one-time check through the Xiaomi website.
Important: IMEI and SN can be checked an unlimited number of times, and the code on the sticker can only be checked once, and if you've already activated the device, you can't recheck it through that code, and fraudsters often open boxes, remove the protective layer, and forge stickers -- a product that seems to have no autopsy marks when they buy it.
Where to look for authentication codes on Xiaomi devices
The location of the identifiers depends on the type of device, and below is a table with the exact places where to look for codes for popular categories of Xiaomi equipment:
| Type of device | IMEI | Serial number (SN) | Verification code |
|---|---|---|---|
| Smartphones (Redmi, POCO, Mi) | Sticker under the battery, Settings → About the phone → General information, box | There. + tray-tray SIM-map | Sticker on the box (under the protective layer) |
| Smart watches (Mi Band, Watch) | — | On the back of the body (under the strap), in the Mi Fit application | The sticker on the box |
| Routers (Mi Router, AX3000) | — | Underbody sticker of the device | The sticker on the box |
| Laptops (Mi Notebook) | — | Sticker under the battery, in BIOS (F2 when booting) | The sticker on the box |
⚠️ Note: On counterfeit devices, codes are often duplicated or consist of repeating digits (e.g., 123456789012345). IMEI and SN It always has letters and numbers in random order, and if you see a sequence like 888888888888888, you're 100% fake.
Take a picture of the sticker on the box (before opening)
Compare the SN on the box and in the device settings
Check the IMEI with *#06# (must match the sticker)
Use the official Xiaomi service for verification code-->
How to verify authenticity through Xiaomi’s official service
The only reliable way to confirm originality is to use the official verification tool from Xiaomi.
- Go to the site. mi.com/global/verify (The domain should be global, not regional. mi.com/ru).
- Enter the 20-digit verification code from the sticker on the box (not SN or IMEI!).
- Enter the captcha and press Verify.
- The system will show the model of the device, the date of production and status (Genuine - original, Fake - fake).
🔍 What to do if the service makes an error:
- 📦 The code's already used. → The device was opened or forged sticker.
- 🌐 "Invalid code" → You may have entered SN instead of a verification code, or it's a fake.
- 🔄 The site won't open. → Check it out. VPN (The service may be blocked in some regions).
Example of the real service response for the original Redmi Note 12
⚠️ Warning: Fraudsters create copies of the official service on domains like mi-verify[.]com or xiaomi-auth[.]net. Always check the address bar - the real service only works on the domains. mi.com/global/verify. Fake sites can show false Genuine status even for counterfeit devices.
Alternative methods of authentication
If the verification code has already been used or not (for example, on used devices), use these methods:
1. Verification of IMEI through databases
IMEI smartphones Xiaomi can be checked through international databases:
- 🔍 IMEI.info – shows the model, year of manufacture and country of manufacture.
- 📱 SNDeeP.info – specializes in Chinese brands, provides detailed information about firmware.
On counterfeits, IMEI is often owned by another brand (such as Samsung or Huawei) or marked as Blacklisted (stolen/blocked).
Serial number analysis (SN)
Xiaomi’s serial number contains encrypted model and production date information, such as the K65A1B2C3D4E5F6 SN, which stands for:
- K65 is the model code (Redmi Note 12 = 2304).
- A1B2 is the week and year of production (e.g. 3223 = 32nd week of 2023).
- C3D4E5F6 is a unique device identifier.
💡
To find out the model by code in SN, use the MIUI ROM database. Enter the first 4-6 characters of SN - the system will show the exact model and modification.
3. Check through the Mi PC Suite app
If the device is already activated, connect it to a computer with the Mi PC Suite installed. The program automatically checks the SN with the Xiaomi base and shows the warranty status. Note: on fakes, the Mi PC Suite either does not recognize the device or gives an error Device not supported.
Signs of fake Xiaomi devices: what to look for
Even if the authentication codes match, counterfeiting can be traced indirectly, and here are 10 warning signs to alert:
- 📦 Box: No holographic sticker, font blurred, colors dull (original - bright orange-white packaging with a clear logo).
- 🔋 Charging: There is no marking on the power supply unit MDY-11-ED (Xiaomi 33W) or MDY-12-EU (for 67W).
- 📱 Firmware: In Settings → Phone number listed. MIUI Global, but the default language is Chinese.
- 🔊 Speakers: Sound is quiet, wheezing (originally clear high and low frequencies).
- 📸 Photos in low light are obtained in grainy (Xiaomi originals use the Night Mode 2.0 algorithm).
- 🔄 Updates: In Settings → Update of the system no new versions MIUI (The latest relevant - check here).
- 💰 Price: Over 30% off the market average (e.g. Xiaomi 13 Pro for $30,000) ₽ 60,000 ₽).
- 🔧 Assembly: gaps between the case and the screen, backlash buttons (the originals have a perfect fit).
- 🔒 Bootloader: In Settings → Additionally. → There is no unblocking status item for developers OEM.
- 📡 Network: 4G is unstable or there is no support for ranges B20 (800 MHz) (checked through ##4636##).
💡
The most reliable sign of a fake is the lack of official firmware. → The phone is always coded for the model (e.g, 23013RK75C For the Redmi Note 12 Pro+). On copies instead of code is an arbitrary set of characters or the name of the model in words (RedmiNote12Pro).
What to do if the device is a fake
If the test showed that your Xiaomi device is counterfeit, proceed by the algorithm:
- Collect evidence: Photo of a box with stickers (especially the verification code); screenshots of errors in checking on mi.com/global/verify; check or screenshot of the transfer of money to the seller.
Please contact the seller:
Write a claim demanding the return of money or replacement of goods, specify article 18 of the Law on Protection of Consumer Rights (for Russia), in most cases, sellers make concessions to avoid complaints on the site.
File a complaint to the site:
If you bought it on Wildberries, Ozon or AliExpress, use the return form. Attach proof of forgery - sites usually side with the buyer.
Notify Xiaomi:
Write in support of Xiaomi with a description of the situation, the company maintains a database of scammers and can help with the identification of the seller.
⚠️ Note: Do not try to reflash the fake device official MIUI — Counterfeit smartphones are often built on incompatible chips (e.g. MediaTek Helio). G35 Instead of the claimed Snapdragon 685, and the firmware for the original simply kills them.
