How to see Xiaomi number: the complete guide to identification

Every Xiaomi, Redmi, or POCO smartphone owner will have to find out their device’s unique identity sooner or later, which may be required when registering a warranty, filling out a bootloader unlock form, getting insurance, or authenticating a gadget on specialized services. Equipment IDs are not just a set of numbers, but the key to managing access rights and servicing your device.

There are several ways to access this information, and they are not always obvious to beginners. Some methods work even if the screen is broken or the system does not boot, while others require full access to the MIUI or HyperOS interface. In this article, we will discuss all the options available in detail so that you can choose the most suitable one for your situation.

Knowing the exact serial number (SN) and IMEI code is critical to security, allowing you to lock a stolen device at the carrier level or check repair history when you buy used equipment, and we'll look at both software methods through settings and physical ways to verify markings.

⚠️ Note: Never give the full data IMEI And the serial number to strangers on the Internet, and the attackers can use this information to clone the IDs or bypass activation blockers.

Use of the Engineering Menu through USSD-code

The fastest and most versatile way to find out a Xiaomi number is to use a special system query, which works on all versions of firmware, including Chinese (China ROM) and global (Global ROM), and does not require an Internet connection.

Enter *#06# on the dial keyboard, and the system will instantly process the request, and a pop-up window with technical information will appear on the screen, and here you will see the basic parameters:

• 📱 IMEI 1 - the primary identifier of the first SIM-maps (for two-symbol models).
• 📱 IMEI 2 - identifier of the second SIM-Cards (relevant to Dual-SIM devices).
• 🔢 SN — Serial number of the device, unique to each instance.
• 🆔 MEID — identifier CDMA (It is rarely used in the CIS, but is present in specifications).

It is important to note that in some models with virtual SIM-The eSIM card can display additional code EID. If your smartphone supports eSIM technology, this number will be specified in a separate line. The data in this menu can not be edited, it is read directly from the protected area of the memory of the processor.

If nothing happens after you enter the code or if you receive a connection error message, it is possible that the Phone application has been replaced by a third-party analogue (for example, Google Phone or Truecaller), in which case you can temporarily install a standard MIUI call or use other methods described below, and the code may not work on devices with heavily modified system software.

Search for data in the menu "About the phone"

If the smartphone screen is functioning normally, the most detailed information can be found in the system settings, which is convenient because the data here is presented in a structured form, and it is easy to copy it. The path to information may vary slightly depending on the version of the MIUI shell or the new HyperOS.

To get data, do the following: open the Settings app, scroll down the list and select About. In the menu that opens, you'll see the logo of the system version and the main features. However, the full information is hidden inside the submenu.

Click on the MIUI Version (or OS Version) several times in a row (usually 5-7 times) and this action activates the hidden Status or Device Information menu.

• 🔍 Status SIM-maps show the status of the network and IMEI slot-in.
• 🏭 Serial number – often duplicated here for convenience.
• 📶 MAC-address - unique identifier of Wi-Fi and Bluetooth modules.
• 📜 Licenses – information about the legal status of the software.

⚠️ Note: New versions of HyperOS may change the path.Look for General Settings» → «About the device» → «Status if the standard path does not work.

The thing about this method is that it shows not only hardware identifiers, but software versions of components, for example, you can see the baseband version here, which is useful for diagnosing communication problems, and you can copy data from here in one click: just press and hold the right line.

💡

To quickly copy the IMEI from the settings menu, click and hold your finger on the number line – a notification will appear “Copied to the clipboard”.

Verification of information on the body and packaging

Physical storage media are indispensable in situations where the smartphone is completely discharged, broken or not turned on. Factory marking is applied to the case and box at the time of manufacture and is the primary source of truth for service centers. This is the hardware layer of identification.

The location (stickers) depends on the design of the particular device. On modern Xiaomi smartphones with a non-removable battery, the information is most often located in the following places:

• 📦 On the back cover is a fine print at the bottom, often requiring careful consideration in good lighting.
• 🗑️ In the tray. SIM-maps – on some models (for example, the old Redmi Note) the data is microscopically applied to the metal frame of the tray.
• 📄 On the box - a special sticker with barcodes on the side or back wall of the package.
• 🧾 In the warranty card – the data is often copied by the seller or pasted in the form of a sticker.

The factory sticker usually has a few lines on it. IMEI (International Mobile Equipment Identity and S/N (Note that the box may also have a code on it. MAC and ICCID (if the test was included in the test SIM-The data on the box and the system must be completely identical.

When buying a device from hand, be sure to check the numbers on the box (if any) with those displayed in the menu *#06#. The discrepancy even in one digit indicates that the device case has been changed, or you are in front of a restored device ("ref"), assembled from different parts. This is a critical point for assessing the real value of the gadget.

Use of Mi Cloud Account and Google Services

In the cloud age, physical access to a device is not always necessary to obtain its identifiers. If your Xiaomi smartphone has logged in to your Mi Account and synced, the device data is stored on the company's servers, which works even if the phone is lost or stolen.

To view the information, go to the official website of the cloud service at i.mi.com. Sign in using your username and password from the Mi Account. After logging in, go to the Devices section (or click on the smartphone icon in the upper corner), and a list of all gadgets associated with your profile, showing their models and serial numbers, will be displayed here.

Alternatively, Google services are used, and if the phone has been synced to a Google account, information can be found through the Find Device service (android.com/find). However, Google often hides the full IMEI for security reasons, displaying only the model and approximate location. Mi Cloud provides more detailed technical information in this regard.

This method is especially useful for checking whether your account has been lit on someone else's device. If you see an unknown serial number on the list, it is recommended to immediately change your password and check active sessions. Regular monitoring of connected devices is part of basic digital hygiene.

Comparison of IMEI, SN and MAC identifiers

Users often confuse different types of identifiers as synonymous, but each performs a unique function in the mobile and electronics ecosystem, and understanding the difference will help you fill out documents and communicate with technical support.

The table below provides a detailed comparison of the main number types used in Xiaomi devices:

Note the "Variability" column. While technically advanced users can change the IMEI (a process known as "IMEI change" or "IMEI repair"), in most countries this action is illegal and punishable by law. Serial number (SN) is almost impossible to change without replacing the motherboard, since it is stored in a protected memory area (RPMB).

When you contact an authorized Xiaomi partner service center, you will always be asked SN and IMEI. These data allow engineers to see the history of the device: date of activation, previous repairs and region of origin. If you plan to rent the phone under warranty, make sure that these numbers on the case match the data in the check.

💡

Serial number (SN) is the main key to warranty service, while IMEI is required for mobile networking.

Frequent problems and ways to solve them

Users may encounter anomalies in the search process, such as zeros (000000000000000000000000) or dashings in the IMEI field, indicating a serious problem: either the NVRAM partition (where the modem calibration data is stored) is damaged or the antenna module's plume has moved away.

If you see zeros instead of IMEIs after flashing the device, the partition structure is likely to have been damaged, in which case standard recovery methods will not help. You will need to use specialized engineering software (for example, QCN files for Qualcomm processors or MTK tools for MediaTek) to restore factory identifiers. Without the correct IMEI, the phone will not be able to register with the operator network.

Another common situation is data discrepancy, where you have one number on the settings menu, and a sticker under the battery (if it's removable) or in the check, another number, which is a red flag, which is probably a device made from several ("Frankenstein"), or it's been officially restored in the factory, but the sticker has been forgotten to re-patch, and it's risky to buy one of these devices from hand.

⚠️ Attention: If IMEI lost after the system update, in any case do not try to reset to factory settings (Wipe Data) without creating a full backup.

To diagnose the modem, you can use a hidden test menu. Enter the code ##4636##. Select "Phone Information" here, which shows the actual registration status on the network. If the IMEI field is empty or zero, the problem is hardware-software in nature and requires the intervention of specialists.
