Buying a smartphone is always an exciting process, especially when it comes to the popular Xiaomi brand. The electronics market is full of offers, and among them it is easy to stumble upon restored devices or, worse, fakes. Which is why the question of how to check the phone for warranties or not becomes a priority for every buyer, it directly depends on whether you can count on free repairs in case of a breakdown.
The Chinese giant's verification system is well developed, but it requires care, and its warranty status is tied not just to a check, but to the unique identifiers of the device itself. In this article, we'll take a look at all the methods available, from official services to hidden engineering menus, and learn to distinguish the original from the replica and understand whether your gadget has expired.
Ignoring verification can backfire. Imagine a situation where a smartphone screen goes off a month after you buy it, and the service center tells you that the device was listed as activated two years ago. To avoid such scenarios, you need to know where to look for reliable information. We'll look at both online services and verification methods without the Internet.
Why do I need to check the status of the device
Many users believe that having a box and a check automatically guarantees service, a dangerous misconception. Xiaomi's official warranty is often tied to the date of the device's first activation or first online registration. If the phone was activated long before you bought it, its free service may already be exhausted.
And there's also the risk of buying something called a gray product, which is original, unofficially imported, and may have global firmware, but your country's authorized service centers may not be able to repair it, and IMEI checks you to see where the device originated.
⚠️ Warning: Buying a smartphone with your hands without prior verification IMEI You can use official databases to get a lottery with a low chance of winning, and you can buy a device that's been stolen or locked under a contract.
Also, the check is necessary to identify the interlaced cases: Unscrupulous sellers can replace a broken screen or back cover with non-original parts, giving the phone a new one, and a mark of previous requests to the service can be stored in the database.
💡
The most reliable way to verify the legality of the device is to check the IMEI on the box, in the system and in the warranty card with the data on the official website of the manufacturer.
Check by IMEI via the official Mi Verify website
The fastest and most reliable way is to use the Mi Verify portal, which is a global system that aggregates data on all released devices. First, you need to know the IDs of your smartphone, and you can do this by looking under the back cover (if it is removable), looking at the box or settings of the system.
From the smartphone menu, go to Settings → Phone → General information. There you will find the IMEI and SN strings. Copy this data. Next, open your browser and go to mi.com/global/verify. Enter CAPTCHA and the numbers you ask for.
- 📱 Enter the 15-digit code. IMEI field-wise.
- 🔢 Enter the serial number (SN), If the system requires additional verification.
- ✅ Press the Verify button and wait for the result.
- 📅 Pay attention to the expiration date of the warranty if it is displayed.
If a site says "Product verification successful," it means you have the original, but it's normal to not know the warranty expiration date at this point, and it often requires registration with a Mi Account to activate the countdown.
Use the Mi Store app to activate
In some regions, including Russia and the CIS, the Mi Store app, formerly called Services and Support, is still relevant, and it is a good method for not only checking the status, but also officially starting the countdown of the warranty period, if it has not already begun.
Run the app on your device. It's usually pre-installed on your system. If you delete it, you can download it. APK-In the main menu, find the "Authentication" or "Warranty" section.
It is important to understand the difference between the global version and the Chinese version, which, for the Chinese version (CN Version) with the global firmware, may not work or show the wrong region, in which case the warranty can only be valid in the country of purchase, that is, in China.
| Parameter | Global version (Global) | Chinese version (CN) | Indian version (IN) |
|---|---|---|---|
| Guarantee region | Country of Purchase/Europe | China | India |
| Support | Complete for RF/CIS | May be missing B7, B20 | Specific frequencies |
| Checking the site | It's stable. | Requires VPN/China region | Separate portal |
| Tongue in a box | Russian, English | Chinese, English | Hindi, English |
If the app shows that the device is not found, it may mean that it is not yet registered in the activated device database, which often happens with new models in the first weeks of sales, in which case it is worth waiting or contacting the seller.
What if the device region is not the same as yours?
Checking through the engineering menu and USSD-code
When you don't have access to the Internet, or you need to quickly check the hardware with what's written on the box, you use built-in commands to output information directly from the smartphone's communication modules, which helps identify oversold or cloned IMEIs.
Open the Phone app and type the universal code *#06#. All identifiers will appear on the screen instantly: IMEI 1, IMEI 2 (for two-simulated models), serial number and MAC-This data should match one-to-one with the sticker on the box.
*#06# - IMEI and SN display
#6484## - Engineering Menu (CIT)
#4636## - Testing menuFor a deeper diagnosis, you can use the CIT menu. Enter ##6484##. This is a hidden section for hardware testing. You can check the sensor, the cameras, the microphones. While this does not give direct information about warranty, a broken CIT menu is a sure sign of deep flashing or forgery.
⚠️ Warning: Do not change the settings in the engineering menu unless you know exactly what they are responsible for. Resetting the screen or communication module calibration can lead to malfunctioning of the device, which is difficult to fix software.
Compare the number of IMEIs. If you have a dual-symbol phone and the code only gives out one number or strange characters instead of the second, it's a sign of serious hardware modification.
💡
Take a picture of the IMEI screen immediately after the box is turned on, which will be your proof that the device was intact when it was unpacked, if you have to argue with the seller.
Analysis of the guarantee card and check
Paper media still play an important role, especially in post-Soviet countries, and Xiaomi’s official retail warranty is often provided by the store, not the manufacturer, in the first 14-30 days, so the check is critical.
The warranty card must include the model of the device, its serial number, IMEI, date of sale and the seller's seal; the absence of a seal or an indistinct record can cause a denial of service; check whether the model in the documents matches the real one (for example, M2102J20SG).
- 📄 Check the availability of round stamp of the store on all pages of the ticket.
- 📅 Make sure the date on the check matches the activation date (if known).
- 🔍 Look for a hologram or a special distributor sticker on the box.
- ✍️ Make sure the seller has entered the device data legibly, without corrections.
E-checks are now considered paper checks, save a letter from the store or a screenshot from the bank's personal account with a note of purchase, and when you contact a service center, you often just need to give an order number or show it. QR-bank-app.

Frequent problems and ways to solve them
Users often experience a situation where the site writes "Invalid IMEI" or shows the expiration date of a warranty that has already passed. In the first case, this may mean that the device is too new and the base has not yet been updated, or it is a deep fake. In the second case, the phone may have been activated earlier (window sample, return).
If the site doesn't see the device, try to enter data without spaces and dashes. Sometimes it helps to change the browser or use incognito mode. For Chinese versions, you may need to switch the region on the site to China.
If there is a discrepancy between the box and the system, immediately bring the device back to the store, which is the basis for a refund as for goods with defective configuration or identification, the operation of such a phone may be unsafe.
⚠️ Attention: If IMEI If you read "000000000..." or have many zeros, it's a sign of a modem malfunctioning software or using illegal methods to unlock the bootloader, and you can refuse to repair it even for money.
The standard warranty is 12 months, but under consumer protection laws in many countries, it is up to the seller to prove the user's innocence in the first 6 months (and sometimes even a year).
