Users often get confused about the Chinese manufacturer’s nomenclature when they see one name on the box and another in the settings, not a system error, but a feature of Xiaomi’s marketing strategy, which releases the same devices under different names for different markets. For example, the popular Redmi Note in China can come to Europe as Poco or Mi, which creates confusion when searching for firmware or accessories.
Determining a specific modification is critical not only for curiosity but also for practical tasks: finding compatible cases, buying original parts or manually flashing the device. If you try to install global firmware on the Chinese version without unlocking the bootloader, the phone can turn into a brick.
In this guide, we will take a look at all the identification methods available, from simple inspection of the case to the use of engineering codes and computer utilities, learn how to distinguish between regional codes, understand the difference between CN and Global versions, and learn where real information about hardware is hidden, which is not always shown in the standard menu.
Visual identification through stickers and body
The fastest and most reliable way to find out basic information about a device is to inspect its physical shell. The back of the original devices always has a factory sticker containing key data. Even if the used phone and the sticker are erased, the information is often duplicated on the box itself in the form of a barcode with an alphanumeric code.
Note the Model line. This is the unique identifier of the hardware platform. For example, the M2101K7BG code tells a power user much more than the commercial name "Redmi Note 10 Pro." It's the code that selects compatible displays and batteries in service centers.
⚠️ Warning: Don't blindly trust the labels on the factory screen protector tape, which often lists the general marketing name of the series rather than the specific modification of your instance.
The region for which the device is released is also important. Chinese versions (CN) often have a two-symbol hybrid slot and support for specific LTE frequencies that differ from European (EU) or global (Global), on the box this is indicated by the corresponding letter indexes at the end of the model number.
💡
Save a photo of the back sticker right after you buy it, and it will erase over time, and you will need that information when you sell the device or contact customer service.
Version definition through the Android settings menu
The MIUI or HyperOS shell interface provides basic information to the user, but it is often hidden behind marketing names. To get to the technical data, you need to go to Settings → About the phone. Here you will see in large print the model name, which may differ from the real code.
To get detailed information, you need to do several taps on the operating system version. Once you activate the developer mode or view it in detail, the system will display the device model string, which is the code you should use when searching for drivers or instructions in forums.
☑️ Checking the data in the menu
It is important to distinguish between the MIUI version and the Android version. The first is the add-on from the manufacturer, the second is the underlying operating system. When searching for firmware, you will need to know both numbers, since switching from one version of Android to another (for example, from 11 to 12) requires different update packages.
Sometimes you can find information about the processor and the amount of RAM in the same menu, but this data can be changed by unscrupulous sellers on AliExpress.
Use of the engineering menu and USSD-code
For more in-depth diagnostics, there is a special mode available through a set of phone codes, which is the gold standard for authenticating components and obtaining hidden build information. Enter the code ##6484## on the dialing keyboard to get into the CIT (Customer Interactive Test) menu.
Not only can you find out the version, but you can also test all the sensors, screens and communication modules, and navigation is done through the menu items, where the "Version" or "Information" section often spells out the exact SKU (Stock Keeping Unit) of the device, which is especially useful if the phone is hand-built and you want to make sure that the screen or battery has not been replaced with cheap ones.
⚠️ Warning: Be careful in the engineering menu. Changing the settings in the sections associated with screen or radio calibration can disrupt the device.
Other useful code — *#06#. It's mapping. IMEI-SIM card codes and, often, serial number (S/N). By serial number on specialized sites, you can determine the date of activation of the device and its initial sales region, which helps to identify “gray” imports.
What if the code doesn't work?
Analysis of characteristics using third-party applications
When standard tools are not enough, specialized utilities come to the rescue, reading data directly from the system files of the kernel, and the leader in this field is the CPU-Z or AIDA64 application, which shows not only the name of the model, but also the real resolution of the matrix, the type of camera sensor and the frequency of the processor.
These programs are indispensable when buying a used phone. Vendors often overclock the software display of memory, but the hardware is harder to fool. If the settings are 8 GB of RAM, and the CPU-Z shows 4 GB, you have a re-energized clone or a device with a modified system partition.
| Parameter | Where to look. | Value for verification |
|---|---|---|
| Model of the device | Settings / CPU-Z | Code like M2101K7BG |
| Screen resolution | AIDA64/Display | Real pixels (not DPI) |
| Android version | The phone. | Basic version (11, 12, 13) |
| Core system | CPU-Z | Kernel Linux version |
Using these applications also allows you to see the exact model of the processor (SoC). In the line of Redmi and Poco often come versions with different chips (for example, Snapdragon and MediaTek) under the same name. Only detailed software will show this difference.
Differences between Global, EU and CN versions
Understanding the difference between regional versions is a key skill of the Xiaomi owner. CN (China) versions often don’t have Google Play preinstalled (although it can be installed), support fewer languages and use other communication frequencies, and their firmware is tailored to Chinese services.
Global versions are designed for the whole world, have full localization, support for all necessary LTE and Band 20 frequencies, which is critical for high-quality communication in rural areas of Russia and Europe. EU (Europe) versions are a subset of global, but with even more stringent radiation standards and sometimes different delivery kit (for example, the lack of a charging unit in new models).
They can be distinguished by the code at the end of the model number or by the first characters of the MIUI version. Global firmware usually has the mark MIUI Global or the letter X in the firmware code, while Chinese ones are MIUI China or the letter C.
💡
Buying the Chinese version (CN) is often cheaper, but requires Google services to be installed on your own and may have trouble with notifications and navigation.
Authentication through the official website
The most reliable way to make sure you are holding the original rather than the fake is to check the IMEI on the official portal. Go to mi.com/global/verify and enter the code obtained via *#06#.
If the site gives an error or shows a device of a different color/model, it is an alarm, it may be a phone made from different parts or a Refurbished that is sold as new, it will also help to know whether the phone was stolen and blocked by IMEI in the country of origin.
Regularly checking the device version helps to learn about available security updates in time. Xiaomi actively patches vulnerabilities, and knowing the exact version allows you to manually download and install a fix if an automatic update for some reason did not come.
