The smartphone market is crowded with devices, and buying a gadget from hand or doubtful sellers always carries risks. IMEI verification becomes a must for any Xiaomi owner who wants to verify the authenticity of his purchase. This unique identifier contains all the key information about the device, hiding the history of its movements and the status of locks.
Many users are faced with a situation where the seemingly perfect device is restored or stolen, which is why it is important to know where to look at the factory code on the box and in the menu of the smartphone to match the data, ignoring this step can lead to the purchase of a useless “brick” that can not be unlocked or used in the networks of operators.
In this article, we will take a look at all the verification options available, how to distinguish the original from the copy using the manufacturer’s official resources and third-party databases, and this knowledge will help you avoid fraud and save you significant money.
⚠️ Warning: Never report your own IMEI-Fraudsters can use this information to clone a number or lock the device through an operator.
What is IMEI and where to find it on Xiaomi
IMEI (International Mobile Equipment Identity) is a 15-digit international mobile device identifier that is assigned to every device in the cellular network at the manufacturing stage, and for Redmi and POCO smartphones, this code is a kind of digital passport, without which normal networking is impossible.
There are several ways to find this number on your device, and the fastest way is to use the engineering menu, so you have to open the Phone app and dial the universal combination:
*#06#Once you enter the last digit, the screen automatically pops up with information. If you have a dual-sim device, you will see two codes: IMEI 1 for first SIM-maps IMEI 2 for the second. You need to write both, but the first one is usually enough to check.
Also, physical marking is always present on the case. On older models, the sticker is under the back cover, next to the battery. In modern monolithic designs, Xiaomi information is duplicated on the factory box and sometimes on the tray for the battery. SIM-cards (requires the extraction of the tray and careful inspection under increasing).
💡
Before buying a used smartphone, be sure to check the IMEI on the box, on the sticker at the back (if any) and on the engineering menu.
Official check on the Mi Verify website
The most reliable source of information is the official portal of the manufacturer, Xiaomi has created a special service to confirm the authenticity of the device, but it is worth noting that this tool is primarily focused on authentication, not on location.
The verification process is simple and doesn't require registration. You have to go to mi.com/verify and enter a 15-digit code. The system will instantly process the request and give the result. If the device is genuine, you'll see the corresponding message and phone model.
- 📱 Enter the code without spaces and additional characters.
- 🌐 Website may be slow due to servers in China, be patient.
- ✅ Green tick means that the device is listed in the database issued.
It is important to note that having a record in the database does not guarantee that the phone is not stolen, it is only confirmation that such a phone was made by Xiaomi.
☑️ Check on the official website
Verification of the activation date and warranty
One of the most important parameters when buying used equipment is the warranty period and the date of the first activation. Xiaomi's official website allows you to check this parameter. Often unscrupulous sellers pass old restored devices for new ones.
For this information, go to mi.com/global/verify. Once you enter the data, the system will show an approximate activation date. If you are told that the phone is “just unpacked” and the service shows activation a year ago, this is a clear sign of resale or recovery.
It also provides an estimate of the end of official support, which is critical for Mi and Redmi Note devices, as it is crucial to getting security updates and Android versions.
⚠️ Note: If the activation date is displayed as “Unknown” or significantly different from the purchase date, this may indicate a gray delivery or flashing of the device, bypassing regional restrictions.
Sometimes the system may not find activation data, which is normal for devices that have never connected to the Internet after a reset, or for very old models that have gone out of support, in which case you should only focus on the external signs and battery status.
Why can the activation date be incorrect?
Third-party services for detailed verification
When official tools are not enough, third-party databases come to the rescue, aggregate information from telecom operators, service centers, and reports of theft, and one of the most popular resources is IMEI.info or Sndeep.info.
These sites provide much more detailed technical information, you can find out the exact model, color, memory capacity, and even the factory where the device was assembled, and for enthusiasts, it's an opportunity to check whether the motherboard or screen has changed.
| Service | Type of data | Cost | Reliability |
|---|---|---|---|
| Xiaomi Official | Authenticity, Guarantee | Free of charge. | Tall. |
| IMEI.info | Specifications, Blacklist | Paid/Free | Medium |
| Sndeep.info | Lockdown status, Theft | Paid. | Tall. |
| GSMA Device Check | Global blacklist | Free of charge. | Tall. |
Using paid reports only makes sense when buying an expensive flagship. For low-end models, Redmi or POCO usually suffices for free authentication. Paid reports often contain information about whether the device is listed in the database of lost or stolen.
How to know if your phone is blacklisted or not
Buying a Blacklist phone is a guarantee of future problems, which are blocked by network-level carriers and cannot be inserted into them, most often involving phones purchased on credit that the owner stopped paying, or stolen gadgets.
GSMA database check is an international standard, and if a phone is listed there, it will be "locked" anywhere in the world, and for Xiaomi owners, this is especially true because the brand is popular globally.
To carry out the check:
- 🔍 Go to the site. imei.info/check or similar.
- 📝 Enter the 15-digit code of your device.
- 📉 Note the status of "Blacklisted" or "Clean".
If you find that the device you bought is blacklisted, you should immediately contact the seller and demand a refund. Using such a phone is not legally possible, and unlocking through gray services is often temporary and unstable.
💡
Being blacklisted most often means that the previous owner has stopped paying the loan for the phone and the bank has applied to lock the device.
Frequent problems and errors in the inspection
Verification often faces technical difficulties; Xiaomi servers can be overloaded, especially during peak hours or when new models are released; System busy or endless download errors are typical symptoms.
Another common problem is region mismatch: If you check the Chinese version of Xiaomi (CN Version) on a global site, the data may be undecided or displayed incorrectly, in such cases, it is worth trying to switch the region on the site to China or use a VPN.
There are also cases where the IMEIs on the box and the phone are different, which is a sure sign that the motherboard or the case has changed in the device. It's not acceptable for the original state. If the numbers don't even match one, you better give up.
Don't trust apps in the Play Market that promise to break through the phone, often just duplicate information that the system already shows, or contain ads, and use a browser and verified web resources.
