Owning a Xiaomi smartphone requires careful attention to its identity, especially if you are planning a hand-held purchase or are making a warranty. IMEI (International Mobile Equipment Identity) is a unique fifteen-digit code that is assigned to each mobile device during production. It is this number that allows you to track the history of the gadget, find out the date of activation and even block it in the event of a theft. For owners of Redmi and Poco, this information becomes critical, as there are many replicas and restored models on the market.
IMEI checks to make sure that you are not looking at a designer of different parts, but rather at the original device that came off the factory line. Inconsistency of codes specified in different places can signal serious repairs or illegal importation of equipment. In today's digital fraud, the ability to quickly and accurately check this number becomes a basic skill of any user.
In this article, we will discuss in detail all available methods of verification, from simple to simple. USSD-Android provides multiple levels of access to this information, and each of them is worth checking. This will help you avoid buying a stolen device or a device with modified firmware.
⚠️ Note: Never post your full post. IMEI Fraudsters can use this number to clone your device or lock your phone through a carrier.
Visual inspection on the body and packaging
The first and most obvious step to take immediately after unpacking or before buying is a physical examination. IMEI It's actually put on a factory sticker on the back of the box, and it's often duplicated on the back of the device, if it's matte, or under the tray. SIM-maps in older models.
So, carefully compare the numbers on the box to the numbers on the system, and the identity of the data is the first sign that the box is "native" and has not changed. If there is one number on the box and another number on the phone, it's a cause for concern. Often, fraudsters re-paint the stickers on the packages of refurbished devices to sell them as new.
Pay attention to the quality of printing barcodes and numbers. On Xiaomi original products, all characters are clear, smooth and easy to read. Blurred numbers or stickers that are easy to peel off may indicate a homemade build. SIM-maps: many models of Redmi Note or Mi IMEI laser-knocked right on the metal frame of the tray.

Use of the engineering menu and USSD-code
The fastest way to find out the ID number is to use standard Android commands. You don't have to install third-party apps or search for settings in the depth of the menu. Just open the Phone app and enter the universal code *#06#. Once you dial the last grille on the screen, the system window with the information will automatically open.
In the window that appears, you will see one or two numbers. IMEI, If the device supports two SIM-And the code can also be displayed here. MEID net CDMA and serial number S/N. This data is read directly from the modem memory, so it is extremely difficult to forge it through the program menu, and if nothing happens after entering the code, it can mean that the firmware of the device is modified or damaged system part.
For a deeper diagnosis, engineers use a hidden engineering menu CIT. To get there, you need to enter the code ##6484## or go to the settings through the debugging menu, and you can check not only the number, but also the radio module in real time, which is especially useful if the phone is not catching the network well or you have problems with determining the number. SIM-map.
💡
If *#06# doesn't work or gives you an error, try restarting the device. In rare cases, on custom firmware, this functionality can be disabled by developers.
Search for IMEI through smartphone settings
If the phone screen is broken or the sensor is intermittent, enter USSD-The code can be problematic, and then the standard operating system settings menu comes to the rescue. MIUI The path to information may vary slightly depending on the shell version, but the logic remains the same for all Xiaomi devices.
You need to go to Settings, then select About Phone, and you need to find General Information or see the data block immediately, and you need to specify all the identifiers you need, and this is a reliable method because the information is taken from the system partition, which is protected from random user change.
For the convenience of users, the copy function is often available in the same menu. By clicking on the corresponding icon or highlighting the text, you can copy. IMEI This is convenient if you need to send data to a service center or register a device on the operator's website. USSD-code.

Authentication check on the official website
Once you get the code, you need to verify its legitimacy. Xiaomi's official website provides a special service to verify the authenticity of products. Go to the authorization or device search page and enter a 15-digit number. The system will check it against the global database of manufactured devices.
If the device is original and has not been tested before, the system will confirm its status. However, if you see a message that this code has been checked many times, it is an alarm. Mass checks often mean that the phone is sold by dealers or was in use, and the site will show the model of the device and the region for which it is intended (Global, China, EEA).
It's important to understand that the site only checks for the existence of a number in the factory database, it doesn't tell you if the phone is wanted or pawnshop-based, but there are other, more specialized services for that, but the official check is the base from which to start, and it confirms that this is not a cheap copy with resold fees.
💡
The official website only confirms the existence of the number in the manufacturer’s database, but does not guarantee that a specific phone in your hands was not stolen.
Analysis through service centers and databases
For more in-depth analysis, you can use third-party, but verified services that aggregate data from operators and service centers, which allow you to see the date of first activation of the device, model and sometimes even warranty status, this is especially true when buying Xiaomi equipment imported from China.
The table below shows the main parameters that can be learned through the different types of checks and their value to the user:
| Verification parameter | Where to look. | What does it mean? | Importance |
|---|---|---|---|
| IMEI match | Box, menu, website | Integrity of device | Critically. |
| Activation date | Official service | Beginning of the guarantee | Tall. |
| Region of version | Manufacturer's website | Global / China / RU | Medium |
| Blacklist status | Operator bases | Theft/Debts | Critically. |
If you bought a global version and the China Version check shows you, you've been sold a re-flashed device. These phones can have problems with notifications, banking applications and communication frequencies. Flashing the Chinese version to a global version often requires unlocking the bootloader, which doesn't always go smoothly.
Frequent problems and possible errors
In the process of validation, users often encounter situations that cause confusion, such as IMEIs that can be displayed as "Null", "Unknown" or consist of zeros, a sure sign of software failure or damage to the NVRAM partition where the modem calibration data is stored, such as after failed firmware experiments or virus attacks.
Another common problem is the discrepancy between software versions and model data, where a site can show one model and the settings indicate another, and this is often the case with devices designed for the domestic Chinese market that have been cross-flashed with global firmware without changing their identities, in which case some features, such as Google Pay or 5G networks, may be limited.
If you find that the phone is blacklisted, you can't use it for its intended purpose: carriers will block access to the network, and it's extremely difficult to get money back for such a device, especially when you buy it from hand, so checking through IMEI databases before transferring money is a ritual.
⚠️ Note: If you enter the *#06# code, you see a message "IMEI null, don't try to search the phone right away. Contact the service, as self-acting can permanently "block" the radio module.
