Owning a modern smartphone means not only enjoying its functionality, but also being responsible for its identification on global networks. Xiaomi brand devices, which have become incredibly popular due to the ratio of price and quality, like any other technology, have unique digital passports. These codes are necessary to register a warranty, unlock the bootloader, link to a Mi Account or check the device for theft. Often users are faced with a situation when they need to urgently dictate this data to the support service or enter it into a form on the official website, but there is no box at hand.
There are several reliable ways to access this hidden information, and they don’t require you to have access to it.-root The hardware identifiers are factory-stitched and stored in a secure memory area, so you can get them from a locked screen in an emergency. From standard system settings to engineering codes that not all smartphone owners know.
Understanding where to look for this data will save you time and nerves at a critical time. Whether you have a budget Redmi or a flagship Xiaomi, the principles of access to information remain the same across the MIUI and HyperOS ecosystem. Let's move from theory to practice and look at specific algorithms of action.
Use of the Engineering Menu through USSD-code
The fastest and most time-tested way to find out device identifiers is by using a special system query, which works at the core level of the Android operating system, so it is available even if the smartphone is not connected to the Internet or installed on it. SIM-You don't have to look for the right items in the confusing settings menu.
Just open the standard Phone app and go to the dial tab. Enter the *#06# combination. Once you enter the last grille symbol, the system automatically recognizes the command and opens a pop-up. The screen instantly displays all the key information about your gadget.
- 📱 IMEI 1 and IMEI 2 – unique numbers for each SIM card slot used by telecom operators to identify a subscriber in the network.
- 🆔 Serial Number (SN) — Serial number of the device, which is often required to register on the official website or when contacting the service center.
- 📟 MEID — network-identifier CDMA (It is important for some models sold in the region).
Please note that if your smartphone supports two SIM-The maps, you'll see two different IMEI-This is normal, because each radio module must have its own unique identifier. IMEI The 15-digit system is the main parameter by which police can track a stolen phone or block its use from a particular operator.
What if the code doesn't work?
Search for information in system settings
If for some reason you are unable or unwilling to use USSD-And the way that you do that is you duplicate all the information that you need in the operating system interface, and it's more visual and convenient if you want to copy a number or take a screenshot of it to send to someone, and the path to data can vary slightly depending on the version of the shell. MIUI or hyperos.
To start, unlock the screen and find the Settings icon (cogs). Scroll down the list and select About. This is where all the technical information about your device is collected. At the top of the screen, you'll see the logo of the system version and the image of the smartphone.
The algorithm of actions depends on the firmware version:
- 🔍 In the new versions MIUI You need to find the line “All characteristics” or immediately see the list of parameters, which will be indicated IMEI and serial number.
- 📋 In some assemblies, you need to click on the logo several times in a row «MIUI» or "HyperOS" to open an extended menu with technical information.
- 📑 Also, the data can be hidden inside the General Information section, where you need to go from the main menu About the phone».
It is important to note that this section also shows MAC-The address of your Wi-Fi module and Bluetooth, which you may need when setting up a router or a corporate network where access is only allowed for trusted devices, and copying numbers from here is secure and requires no special permissions.
💡
The About Phone menu is the only legal way to find out the serial number and IMEI if the smartphone screen is broken and the touchscreen does not work, but the image is still visible (when connecting the mouse).
Physical label and original packaging
The most reliable source of truth that can't be changed software is a factory sticker, which is on the back of the smartphone (if the design permits) or on the box in which the device was sold, the only way to check the IMEI if the phone doesn't turn on at all.
The box from Xiaomi or Redmi always has a white label with barcodes.
- 📦 Model of device (e.g, M2102J20SG).
- 🔢 IMEI (usually two numbers for two slots).
- 🏷️ Serial number (S/N).
- 🌐 Regional marking (Global, EU, CN).
If you have a smartphone with a removable back cover (which is common in older models), the label is under the battery. In modern monolithic designs, the sticker is often glued to the back panel or to the tray for the storage of the device. SIM-- The card. SIM-Maps are a small but important detail: on many Xiaomi models IMEI It's engraved right on the metal bar where the SIM is inserted, and you'll have to remove the tray with a paper clip to check it.
⚠️ Warning: Never throw away a smartphone box immediately after you buy it, keep it safe for at least a year (warranty period). In the event of a theft or loss of the device, a photograph of the box with the label will help the police and the operator identify your gadget faster.
Checking through Mi Account and official website
Xiaomi’s modern ecosystem is tied to a single account, and if your smartphone is tied to Mi Account and has internet access, you can find out its number remotely, even if the phone itself is not at hand (for example, it is lost), and this works thanks to the Find Device feature.
Go to i.mi.com from any computer or phone, log in using your Mi Account login and password. Once logged in, select Find Device, your device list will display the model, and when you click on it, you will see detailed information, including IMEI and lock status.
This method is especially useful for authenticating the device before buying from hand. The seller can show a screenshot from his personal account, which will confirm his rights to the device. However, be careful: make sure that the seller logs out of the account after checking, or simply ask him to dictate the number from the settings.
Table: Comparison of methods for obtaining a number
To organize the information and choose the most convenient way for you, we have prepared a comparison table that will help you understand which method is best used in a particular situation.
| Method | Screen on required | Required. SIM-map | Data reliability |
|---|---|---|---|
| Code *#06# | Yes. | No. | Tall. |
| Settings (About the phone) | Yes. | No. | Tall. |
| Box/Sticker | No. | No. | Maximum |
| Tray SIM-map | No. | No. | Tall. |
| Mi Account (Site) | No (remotely) | Internet is required | Tall. |
As you can see from the table, having a working screen is critical to software methods. If the display is broken down into porridge, but the phone responds to touch, you can try connecting it. USB-mouse-wise OTG-adapter and repeat the actions in the settings, otherwise there is only a box or tray of the SIM card.
Authentication and status of the device
Knowing your number is half the battle. It's important to be able to use that data to verify the status of a device. There are many restored or counterfeit models in the electronics market. Xiaomi's official website provides a service for warranty and authentication.
Go to mi.com/verify, enter IMEI or serial number, and also captcha, and the system will give the result:
- ✅ Valid – original device, activation and end date warranty correct.
- ❌ Invalid – number not found in the database, perhaps the device was assembled artisanally or the number is broken.
- ⚠️ Expired – Warranty is over, but the device is original.
It can also check if the phone is on the stolen list (although there is no global database of stolen phones, some local carrier databases can display lock status). If you buy a used phone, be sure to check the IMEI on the box, in the settings and on the site. All three values must match.
⚠️ Attention: If IMEI The phone and the box are different, a sure sign that the motherboard in the phone has been replaced, perhaps by a non-original or a different device.
💡
When buying a used Xiaomi, pay attention to the region of the device. If the settings indicate the region “India” or “China”, and the phone is sold as “Global Version”, this can mean flashing. IMEI reconciliation on the global Xiaomi site will help identify inconsistencies.
