The serial number (SN) of Xiaomi devices is a unique numerical code that allows you to identify the gadget in the manufacturer’s database, which can not only verify the authenticity of the smartphone, but also find out the date of production, the region of sale and even the history of warranty service, but not all users know where to find this number and how to use it correctly for verification.
In this article, we will examine all the official and informal ways to check Xiaomi by serial number, including hidden MIUI features, online services and diagnostic tools. Particular attention will be paid to the risks of buying fake devices, from inconsistencies in characteristics to the complete lack of support from Xiaomi. If you plan to buy a used smartphone or doubt the originality of the new device, this guide will help to avoid fraud.
Where to find the serial number on a Xiaomi device
Serial number (SN) can be found in several places, both on the device itself and in the software.
- 📱 On the box - usually on a barcode sticker (format: SN: XXXXXXXXXXXX or S/N: XXXXXXXXXXXX).
- 🔧 In settings - the path: Settings → The phone. → General information → Serial number.
- 🔋 Under the battery – on some models (for example, Redmi Note) 4X) number is duplicated on the sticker under the cover.
- 🖥️ Through ADB — Adb shell getprop ro.serialno command will be used SN even on a locked device.
Important: on fake devices, the serial number can be swapped or duplicated with other gadgets. For example, scammers often use SNs from real Xiaomi, but they enter them into the clone firmware, so a visual match is not enough, you need a comprehensive check.
💡
If the serial number on the box and in the phone settings do not match, it is 100% a sign of a fake or re-enhanced device.
Xiaomi’s official services for SN check
Xiaomi provides several tools for device verification, and the most reliable is the official support site, where you can check warranty status and authenticity.
- Go to Mi Verify (for global models) or Mi Auth (for Chinese versions).
- Enter the serial number (SN) and IMEI (can be found in Settings → About Phone → SIM Status).
- Fill in the captcha and press Verify.
The system will produce one of three reactions:
- ✅ "Authentication passed - original device, warranty valid.
- ⚠️ "Authentication failed" — SN Not found in the database (possible fake or device not for your region).
- ❌ "This device has been reported as lost/stolen" — Blacklisted gadget (stolen or blocked by previous owner).
| Service | URL | Checks | Limitations |
|---|---|---|---|
| Mi Verify | global/verify | Authenticity and guarantee | Does not work with Chinese models (CN ROM) |
| Mi Auth | order.mi.com/auth | Originality for China | Requires a Chinese phone number for SMS-confirmation |
| IMEI.info | imei.info | Model and year of issue | It does not guarantee authenticity, only technical data. |
⚠️ Note: Xiaomi services may give an error "Too many requests" when used frequently, in which case try to repeat the check after 24 hours or use the same method. VPN s IP country for which the device is intended (e.g. India for Redmi global version).
Checking through hidden menus and engineering codes
If official services are not available or you doubt their results, you can use hidden MIUI menus, which are designed for service centers, but are also available to ordinary users.
The most useful teams:
- 📞 Model code and SN: Enter in the call ##4636## → Choose Phone Information.
- 🔍 Equipment test: ##6484## – checks camera, sensors and display (fakes often give errors).
On fake Xiaomi engineering menus can:
- Not at all (the code does not work).
- Show incorrect data (for example, the Redmi Note 10 Pro model, and the menu displays the Samsung Galaxy).
- Issuing a “Network locked” error is a sign of a locked or re-flashed device.
Model match in ##4636### and box | No errors in ##6484##| Correct IMEI in *#06#| Production date in service menu (must coincide with model release year)

How to recognize a fake by serial number: 5 key signs
Fraudsters are constantly improving their ways of cheating, but there are constant markers of fakes that give out a clone even when the SN matches:
- Incorrect SN format: Xiaomi original numbers are XXXXXXXXX (9-12 characters, letters and numbers) and fakes often use random 1234567890 or repeating characters.
- Model and SN mismatch: The first 2–3 characters of the serial number encode the model. For example, for the Redmi Note 9 Pro, it could be the M200... Check the match in the Kimovil database.
- Mi Account history: The original device is tied to a Xiaomi account when it is first turned on. If the seller claims that the phone is new, but in Settings → Mi Account → The device is not, it is a fake.
- Different SNs in the system and on the box: even if the numbers differ by 1 character, it is a sign of a flashing or clone.
- Suspiciously low price: If the Xiaomi 13 Pro sells 30% cheaper than the market, the probability of counterfeiting is 99%.
Example of a fake SN
Critical detail: fakes often mimic even official Xiaomi services, creating fake checkout pages. Always make sure the URL starts with https://www.mi.com/... or https://order.mi.com/... – scammers use domains like mi-verify.ru or xiaomi-auth.top.
What to do if the serial number does not pass the check
If official services give an error or the data do not match, do not rush to return the device.
| Problem. | Possible cause | Decision |
|---|---|---|
| SN not found in the database | Device for another region (e.g., Chinese version in Europe) | Try Mi Auth service with VPN (IP China) |
| The "Too many requests" error | Too many requests from your IP | Wait 24 hours or use a different IP |
| SN match, but IMEI doesn't | Reflashing or replacing the motherboard | Check the history of repairs through Settings → About the phone → Status |
| Device blacklisted | Stolen or blocked by the previous owner | Require the seller documents on deregistration |
If you bought a device with a problem SN, try:
- 📧 Contact Xiaomi for support (email: support)@mi.com) with pictures of the box, check and screenshots of the error.
- 🔄 Return the goods to the seller – under the Consumer Protection Act (Article 18), you have the right to a refund within 14 days.
⚠️ Note: If the device is locked through Mi Account (requires a previous account when reset), it cannot be unlocked legally. The only way out is to return it to the seller or use it as a brick!

Alternative methods of authentication
If the SN test did not give a clear result, use additional methods:
- 🔍 Verification IMEI: Type *#06# and compare both IMEI It's a box of data. IMEI IMEI.info – the model and the year of release must coincide.
- 📦 Packaging analysis: The original Xiaomi boxes have a hologram with microtext (you can see the Mi logo when zooming in). The barcode should be read by apps like Barcode Scanner and lead to the model page on mi.com.
- 🛠️ Equipment test: Install CPU-Z or AIDA64 — Check that the processor, memory and screen match the specifications stated. For example, the Redmi Note 11 Pro+ The Mediatek Dimensity 920 chip should be in the system, not Helio. G88 (quintessentially).
For maximum certainty, combine all methods.
- Check the SN on Mi Verify.
- Compare IMEI on IMEI.info.
- Run the test equipment in ##6484##.
- Check the package for the presence of a hologram.
💡
If at least one of the tests is not passed, the device is guaranteed to be unoriginal. Even if the SN and IMEI match a fake, the test often comes out of the equipment (for example, a non-functioning NFC or a camera with lower resolution).
Risks of using devices with fake SN
Buying Xiaomi with a fake serial number is fraught with not only moral, but also technical and legal problems.
- 🚫 Lack of updates: fakes don’t get official firmware MIUI, Which leads to security vulnerabilities.
- 🔌 Charging problems: Clones often use substandard batteries that swell or quickly lose capacity.
- 📵 Blocking by the operator: if IMEI fake phone can be blocked in the network (especially relevant for the 4G/5G model).
- 💰 Loss of warranty: even if the device is original, but SN Replacement, service center will refuse repairs.
- ⚖️ Legal liability: in some countries, the use of devices with counterfeiting IMEI/SN is considered a violation of the law (for example, in India - a fine before the 50 000 rupees).
The most dangerous scenario is when the fake is externally identical to the original, but has:
- Cut-down specs (e.g. Redmi Note 12 Pro with 8MP camera instead of 200MP)
- Uncertified hardware (processor from Unisoc instead of Snapdragon)
- Malware (embedded viruses to steal data).
⚠️ Note: Xiaomi counterfeits are often sold on sites like AliExpress or Avito with the wording “1-1 copy” or “premium quality replica”; these devices are not only unsafe, but can also be confiscated by customs when shipped.
