IMEI Check on Xiaomi Redmi: A Complete Diagnostic Guide

A modern smartphone is not just a means of communication, but a repository of personal information, banking applications and digital keys. That is why the authenticity of the device you purchase or the already available Xiaomi Redmi gadget is the first priority for many users. A unique hardware identifier known as IMEI is the main passport of your phone, which can not be changed software without violating the integrity of the firmware.

Knowing how to find and verify this number not only ensures that the gadget is original, but also protects yourself from buying a stolen device or a handicrafted machine. In this article, we will discuss in detail all available methods for obtaining code, how to verify it through official Mi channels and how to deal with inconsistencies.

There are several levels of verification, from simple visual comparison of numbers on the box and in the menu to in-depth analysis of the manufacturer's database. IMEI mismatch in the system and on the box in 99% of cases indicates a replacement motherboard or soldering of the communication module. Let's examine each stage of the diagnosis in as much detail as possible.

How to get IMEI through the MIUI interface

The fastest and most affordable method that doesn’t require an internet connection or a box is to use the system’s MIUI shell tools. Xiaomi engineers have envisioned a universal query that works on the vast majority of mobile devices, including the budget Redmi Note series and flagship lines.

To obtain information, you need to open the application "Phone" (number set) and enter the combination *#06#. Once you enter the last character, a pop-up with technical data will automatically appear on the screen. SIM-maps, the system displays two different identifiers: IMEI 1 and IMEI 2, and the serial number of the device (S/N).

An alternative route is through the settings menu, which is especially convenient if the on-screen keyboard is damaged or does not respond to character input. You will need to go along the Settings path → About phone → General information. Here the data is presented in text form, and you can copy it to the clipboard for later verification.

💡

Record or take a picture of the IMEI immediately after you buy it, and if the phone is stolen, the police will only be able to lock the device on that data if you have proof of ownership of the number.

Note that in some cases, especially on devices with two physical slots, an additional IMEI number reserved by the system may be displayed.However, to authenticate, you always need the first two numbers corresponding to the active SIM card slots.

Physical inspection: box, stickers and tray

The second level of verification involves comparing digital values obtained software with physical media. When you buy a new device in a store, the original packaging is the first document that you need to scrutinize. There is always a white label on the back of the cardboard box with barcodes and a basic set of characteristics.

This label shall clearly indicate:

• 📱 Device model (e.g. Redmi Note 12 Pro)
• 🔢 Number. IMEI (or two numbers for Dual SIM)
• 🆔 Serial number (S/N)
• 🌐 Regional marking (Global, CN, EAC)

It is important to note that on older Xiaomi models, the information was duplicated on a removable battery, but in modern devices with a non-removable battery, this method is not relevant. SIM-cards, although in recent revisions Redmi from marking tray often refuse in favor of minimalism.

⚠️ Warning: If the numbers on the box and on the phone menu are different, it is an alarm, such a device could be in repair with a replacement motherboard, be assembled from different parts or be the result of illegal assembly shops.

Carefully inspect the font on the sticker. Xiaomi original products use high-quality printing, the numbers are not blurred and easy to read. Forged labels often have blurred barcodes or differ in the shade of paper from standard factory marking.

Online authentication check on the official website

The most reliable way to verify the legality of the origin of the gadget is to contact the official database of the manufacturer. Xiaomi has developed a special service Mi Verify, which allows you to check the status of the device by its unique identifier.

The verification process is as follows:

1. Go to the official authentication site (usually available at mi.com/verify or via the "Mi Verify" search).
2. Enter the IMEI number or the S/N serial number previously received in the request box.
3. Check the CAPTCHA to confirm that you are not a robot.
4. Press the "Verify" button.

If the device is original and officially shipped to your region, you will see the exact model name, color and status confirmation. If the service writes "Invalid" or shows a model different from yours (for example, you check the Redmi Note 11, and the system gives out Mi 10), this indicates a forgery or cloning of the ID.

If you bought a device in the early days after global sales, it may not yet be available in the global registry, and in such a situation, the absence of data does not always mean a fake, but requires additional attention to other signs of originality.

Comparative table of verification methods

So for convenience, we can organize these methods into a single table, and this will help you quickly orient yourself as to what is the best way to apply it in a particular situation, whether it's to look at a phone in a store or diagnose a device you've already bought.

Using a combination of methods gives the best result, for example, checking the data from the settings menu with information on the official website eliminates the possibility of software spoofing, when a fake number taken from the original device is displayed in the phone menu.

Experienced users also recommend checking for IMEI matching across different parts of the system, such as the About phone menu and the engineering code input data must be identical, and any discrepancies here indicate deep modifications to the system.

Diagnostics through computer and ADB

For advanced users who want to get the most “clean” data directly from the modem, bypassing possible software masking of the shell, there is a method of checking through the Android Debug Bridge debugging bridge (ADB). This method requires connecting the smartphone to the PC via USB and driver installation.

After activating the developer mode and enabling debugging over USB, follow the following steps:

1. Connect the phone to the computer.
2. Open the command prompt (CMD) or terminal in the ADB folder.
3. Enter the command to check the connection: adb devices.
4. Use the query to obtain system properties: adb shell getprop | grep imei.

adb shell service call iphonesubinfo 1

This command will ask the radio module for subscriber information. In the response data stream (which may look like a UTF-16) character set, you will need to search for sequences of numbers corresponding to your IMEI. This method is difficult for a beginner, but it practically eliminates the possibility of software spoofing data at the user interface level.

It is important to understand that working with ADB requires caution. Incorrect use of commands can lead to unstable operation of the system, although the command to obtain properties is safe (read-only) and does not make changes to the file system.

What to do if the IMEI is not defined or is zero

The situation when zeros (000000000000000000000) or the words "Null" are displayed in the IMEI field is critical, which means that the phone's software has lost communication with the communication module or damaged a special part of the memory where personal data of the modem is stored.

The causes of this problem may be as follows:

• 🛑 Firmware failure: Failed update or flash to custom build without saving backup EFS.
• 🛑 Hardware malfunction: Modem dump, damage to antenna plume or oxidation of contacts after moisture hits.
• 🛑 Software Interference: Attempts to unlock the bootloader or obtain superuser rights (Root) with errors.

⚠️ Attention: Phone with zero IMEI You can't log in to the cellular network. You can't make calls, you can't send messages. SMS Use the mobile internet even if Wi-Fi is working properly.

In most software cases, a full reset to factory settings (Wipe Data/Factory Reset) via the Recovery menu helps. If this does not help, you will need to flash the device using the official Mi Flash Tool utility in Clean All mode. However, if the problem is hardware, you can not do without interfering with memory chips or replacing the modem.
