How to Find Xiaomi Device ID: The Complete Guide

Xiaomi smartphone owners often face the need to know the unique identifiers of their gadget, which may be required to register on developer forums, link the device to a Mi Account, issue a warranty, or even debug complex network connections. Device ID is not just a set of numbers, but the key to managing your gadget at a deep level.

Unlike the usual settings, which display the model and version of Android, hidden settings require a more careful approach. MIUI and HyperOS, based on Android, provide several ways to get this information, but they are scattered on different menus. Some data, such as IMEI, are available immediately, and for others, such as Android ID or Device ID, you will have to use special codes or a computer.

In this article, we will look at all possible methods of searching for identifiers, we will look at both standard paths through the interface and advanced ways for power users. Understanding the difference between different types of ID will help you avoid errors when registering with service centers or installing custom software.

Differences between Xiaomi ID Types

Before you start searching, it is important to clearly understand what code you need. Users often confuse IMEI, serial number and program ID, which leads to problems when filling out forms on official sites. IMEI is an international mobile equipment identifier tied to a communication module, which is used to lock a lost phone by the operator.

The serial number (Serial Number or S/N) is assigned by the manufacturer and used for warranty service. At the same time, Android ID is a software hash that is generated when the operating system first activates, and if you do a full reset (Wipe Data), this ID will change, unlike IMEI, which is sewn into the hardware.

There is also the concept of Device ID in the context of the Xiaomi ecosystem, which is a unique key that links your device to your Mi Account, which is often required to unlock the bootloader. An error in one character when entering this code on the unlock site will result in a failure in the procedure, so be extremely careful when copying.

⚠️ Note: Never give your own to strangers. IMEI Knowing these parameters, attackers can theoretically try to clone the device or block it remotely through search services.

Search for ID through standard system settings

The easiest and safest way to find out basic information about the device is to use the built-in settings menu, which does not require you to connect to a computer or install additional software, but you will find not all the necessary codes, but only the basic ones.

To start, open the Settings app and scroll down to the bottom. You're interested in the About Phone item. When you click on it, you'll see information about the model, the MIUI version, and the processor. To find the serial number, you often need to click on the firmware version line several times, or just look at the list carefully, because the layout of the elements varies from one shell to the other.

In some versions of HyperOS and MIUI, the serial number is hidden by default for security purposes. If you don't see the Serial Number field, try quickly pressing 5-7 times on either the MIUI version or the Android version. This action activates the hidden menu or just displays the desired bar.

💡

If there is no serial number in the About Phone menu, try clicking on the MIUI logo icon at the top of the screen several times – in some builds this opens up advanced information.

For more detailed technical information, such as MAC-You can go to the "Advanced Settings" section of the Wi-Fi and Bluetooth addresses, and here you can see the data in a more technical format. MAC-The address is also a unique identifier of the network interface, which may be required to configure the router or corporate network.

Use of the engineering menu and USSD-code

The engineering menu is a powerful tool that is hidden from the eyes of the average user, and it allows you to access hardware tests and learn deep system identifiers, and entering special codes in the Phone application is the fastest way to access this data.

The most versatile code for Xiaomi is ##6484##. Once the last character (*) is entered, the menu will open automatically, without the need to press the call button. Here you are interested in the "Version" or "CI" section, where Device ID and other factory settings are often spelled out. The interface may vary depending on the regional version of the firmware (Global, China, EEA).

Another useful code is *#06#. It displays on the screen. IMEI-The codes for all SIM cards, and the serial number. GSM-It's a device that works even on a SIM card that's off, and it's a pure data set that's easy to rewrite or take a picture of.

• 📱 ##4636## – Test menu, where you can see usage statistics and phone information, including Android ID.
• 🔧 ##6484## - full engineering menu CIT, Available on most Redmi and Mi models.

It is worth noting that on newer versions of Android (11, 12, 13, 14), Google has restricted access to some identifiers through standard APIs, so some codes may not work or show stubs instead of real values, in which case you have to resort to using ADB.

Getting Device ID through a computer and ADB

If the software methods on the smartphone fail, USB debugging comes to the rescue. This is a professional method that requires a computer (Windows, macOS or Linux) and an installed ADB driver (Android Debug Bridge), which guarantees accurate data that is hidden in the system.

First, you need to activate the developer mode. Go to Settings → About Phone and press 7 times on MIUI Version. Then the Developer Settings menu will appear. Inside, find the USB Debugging Switch and activate it. When you connect to your PC, confirm the debugging permission on your smartphone screen.

adb shell settings get secure android_id

This command will output your device's Android ID to your console, which is a 64-bit number in hexadecimal format, unique to every application and user, but it's the hash that you use for most system needs. If you need Device ID to unlock the bootloader, it's often found in the system files, but it's easier to use special utilities.

You can also pull out the full log of the device through ADB, which will contain all the identifiers. The adb logcat command gives a stream of events in real time, but it is too large for a quick search. You'd better use the adb shell getprop command, which displays all the properties of the system. You'll need to look for lines that contain "ro.serialno" (serial number) or "ro.boot.serialno."

⚠️ Attention: When working with ADB Be careful with write commands. Entering commands into the console should not contain errors, otherwise you can damage system partitions, although reading properties (getprop) is completely safe.

Definition ID via Mi Account and Cloud Services

Xiaomi's ecosystem stores device binding on its servers. If your smartphone is on and has Internet access, you can find its identifiers through a web interface or other device authorized in the same account. This is especially useful if the phone's screen is broken but the sensor is partially working, or the device is not physically available.

Go to i.mi.com and log in to your Mi Account. Find Device will display a map and list of all gadgets associated with your account. When you select a particular device, it will often display its model and sometimes serial number, confirming that the device is properly registered in the cloud.

The Mi Unlock Tool is used to unlock the bootloader on your PC. When you connect your phone in Fastboot mode and launch the program, it reads a unique Device ID and sends a request to the Xiaomi server. If the account is tied, the server returns the confirmation. In the program logs (munlock.log file), you can find detailed information about which ID was sent to the server.

It is important to understand the difference between your account ID and your device ID. Your account is your account (email/telefon), and your Device ID is the passport of a particular piece of iron, and it is automatically linked when you first log in to your Mi Account on a new device, and you can only unlink it through your phone settings or through a service center if you have a check.

Analysis of information on packaging and body

The most reliable source of physical information is the original smartphone box, and there's always a white barcode sticker on the back or side of the package, and it duplicates all the key identifiers: IMEI, S/N, model and color, and it matches the ones that are stitched in the device's memory.

If there is no box, check the smartphone itself. On some models (especially older or market versions), the information can be laser-painted on the back cover. However, in modern Xiaomi with a single body and glass backs, this marking is not. SIM-Sometimes (rarely) you can find microscopic engravings. IMEI, But you don't have to count on it.

For warranty cases, service centers require IMEI matches on the box, check and system (checked by code *#06#). If you buy a used device, be sure to check these three sources. The discrepancy means that the phone is likely to have been repaired with replacement (motherboard) or is restored informally.

Table of the main identifiers Xiaomi

For convenience, we'll organize the knowledge that we've learned. Here's a table that will help you quickly navigate which ID is what you're looking for and where to find it. Keep this information so you don't get confused by the terms.

As you can see from the table, the persistent identifiers are those associated with hardware. Software identifiers are more dynamic, and understanding this difference is critical when troubleshooting or setting up enterprise security profiles (MDMs).

Problems and Solutions in Finding Identifiers

Often, users are faced with a situation where the fields with the ID are empty or display zeros, this can be due to a software failure, in such cases, it helps to reboot the device or re-assign to Mi Account, sometimes the system simply does not have time to sync the data with the server on the first run.

If you use custom firmware (LineageOS, Pixel Experience), access to the original Xiaomi ID can be limited or changed. Modified bootloader and modified system files (build.prop) can hide real data. In such cases, to get the original S/N you will have to temporarily return to stock MIUI.

• 🔄 Reboot – the first action in the glitches of data display.
• 🌐 Sync – Check the availability of the Internet to update your account data.
• 💻 ADB — Use your computer if your phone can see itself but does not show the data in the menu.

There are also fake devices. There are many Xiaomi replicas on the market. Their code is often copied from the original, so they can show the same Android models and versions in the settings. However, when you try to unlock the bootloader or log into Google Play services, these devices will give an error, since their real Device ID is not listed in the Xiaomi databases.

💡

The most reliable way to know all the IDs at once is to combine the *#06# code for IMEI and the Serial Number box.
