How to find out the ID of the phone Xiaomi: the complete guide

Owners of Xiaomi, Redmi and Poco smartphones often face the need to identify their device, which may be required when linking an account, restoring access to the Mi Cloud or contacting technical support. The concept of “phone ID” in the ecosystem of the Chinese manufacturer can be interpreted in different ways: it can be a unique account ID, device serial number or IMEI code.

Misunderstanding of what code is required in a particular situation often leads to errors in data entry, for example, to untie the account after resetting the settings, you need a Mi Account ID, not IMEI. At the same time, to verify the authenticity of the gadget on the official website will require Serial Number.

In this article, we will take a detailed look at all the ways to obtain identifiers, going from standard system settings to using the engineering menu and ADB commands. You will learn to distinguish between identifiers types and understand where to look for the desired digital sequence depending on your goal.

Differences between account ID, IMEI and serial number

Before you start searching for numbers, you need to clearly understand the difference between the main identifiers. Mi Account ID is a unique number of your profile in the Xiaomi cloud system. It is assigned automatically when you register and is not tied rigidly to hardware, it can be transferred to another phone.

Unlike an account, IMEI (International Mobile Equipment Identity) is an international mobile device identifier that is sewn into a device modem and unique to each device, which is used by carriers to block stolen phones and service centers to verify warranties.

The third important parameter is SN (Serial Number), or serial number, which is the manufacturer's factory number for tracking batch and release date, and often it is the SN that is required to activate an extended warranty or authenticate a site.

• 📱 Mi ID: needed to log into the cloud, search for the device and synchronize data.
• 📡 IMEI: It is necessary to lock the lost phone and work in cellular networks.
• 🏭 SN: Used for warranty service and originality verification.

Confusion between these codes is the most common mistake, and if a service asks for an ID to unbundle an account, IMEI will not work. Always specify what you need.

How to find out Mi Account ID through smartphone settings

The easiest and most secure way to find your account ID is to look at your system settings, which works on all current versions of the MIUI shell and the new HyperOS. You don’t need third-party apps or complex manipulations.

To start, open the Settings app and find the Mi Account section (usually at the top of the list). If you are already logged in, you will see your name and avatar. Click on the name bar or the account details button.

The menu that opens, often hidden under Profile or Security, will display an ID field. This is the digital sequence you're looking for. In some versions of the firmware, it may be hidden and require an additional tap to display.

💡

If you don’t see the ID field in your profile, try clicking on the avatar 5-7 times in a row – this is a hidden method of activating the extended menu in some versions of MIUI.

Write down this number or take a screenshot, which you will need if you want to remove the device from the trusted list through the web version of the site or if you forget the password from the account.

Search for IMEI and serial number in the system

When you need a hardware ID, the algorithm changes slightly, and you can find IMEI and SN in the same menu that displays device information, which is standard procedure for any model, whether it is a budget Redmi or a flagship Xiaomi.

Go to Settings → About the phone. This is a summary of the Android version, MIUI version, processor and memory. Find the All settings line or just scroll down to the General Information block.

You'll see the items in the list. IMEI (There can be two if the phone supports two. SIM-maps) and serial number (SN). Clicking on the line with IMEI, you can copy the number to the clipboard, which is convenient for later insertion into forms on the site.

Note that on dual-symbol models, IMEI 1 refers to the first slot and IMEI 2 refers to the second. When you lock a lost device, the operator usually needs one of them, but it is better to provide both.

Use of the engineering menu and USSD-code

There is a universal way to access technical information that works even if the system interface is partially blocked or glitches, using an engineering menu through a set of special code, a method considered classic for the Android platform.

Open the Phone app and type *#06#. No dialing is required, the menu will open automatically after the last character is entered. The main identifiers table will instantly appear on the screen.

Here you'll see:

• 🔢 IMEI 1 / IMEI 2: Basic identifiers of communication modules.
• 🆔 MEID: identifier CDMA-Networks (relevant to some regions).
• 📦 Serial No: serial number of the device.

The advantage of this method is that it's fast, you don't have to wander through the settings menu, but you can't copy text directly from here, you have to rewrite the numbers manually or take a picture of the screen.

Checking identifiers on the box and case

If the phone is turned off, discharged or in a “brick state”, software methods will not help, in such cases, the only clue is the physical media, Xiaomi manufacturers are obliged to apply data to the packaging and, in some cases, to the case itself.

The back of the original box always has a white barcode label on it, and it's IMEI, S/N (serial number) and P/N (part number), and it's duplicated the information that's been sewn into the phone's memory.

On some models, especially those with a fixed battery, the information can be duplicated in fine print on the back of the smartphone itself. However, in modern thin models, this practice has gone away, leaving only engraving on the tray for the user to use. SIM-cards (rarely encountered).

⚠️ Warning: Never throw away a smartphone box immediately after you buy it. Keep it for at least a year. In case of breakage, theft, or warranty issues, a photo of the label from the box is often the only proof of ownership of the device.

The matching of numbers on the box and in the menu (*#06#) is the main sign that you are not a “rephab” (restored by artisanal means) phone, but the original device.

Using ADB commands for advanced users

For those who are not afraid of the command line, there is a most accurate method of obtaining all identifiers, including hidden ones. Using USB debugging (ADB) allows you to pull information directly from system files, bypassing the graphical interface.

To start, activate the developer mode. Go to Settings → About Phone and quickly click on the MIUI version 7 times. Then, in advanced settings, turn on USB Debugging.

Connect the phone to your computer and start the ADB console. Enter a command to obtain system properties:

adb shell getprop | grep -E "ro.serialno|ro.bootloader"

This command will output the serial number and other technical parameters, and a broader query can be used to obtain a complete list of identifiers:

adb shell dumpsys iphonesubinfo

💡

The ADB method gives access to data that can be hidden in a normal interface, but requires drivers and minimal PC skills.

This method is especially useful if the phone screen is broken but the sensor is partially working, or if the system is booting but the settings menu is not available due to errors.

Summary table of identifiers and their assignments

And to structure the information, you can use a table to help you quickly navigate what code to look for in a particular situation, and not all identifiers are equal in importance.

As you can see from the table, Mi Account ID is about software and services, and IMEI and SN are about hardware, and understanding this difference will save you from many errors when filling out forms.

In today's digital security environment, knowing these codes becomes a must-have skill for the user: Keep them in a safe place, separate from the device itself.
