Serial number (SN) and IMEI — This is your device's passport, and you can find it in a number of places, but scammers often forge the very tags that are easiest to change (like the sticker on the box or the data in the settings).

Official sources SN/IMEI (From most reliable to least reliable):

• 📄 Under the battery (for models with removable cover: Redmi) 4A, Redmi 5A et al. - here SN It is often duplicated on the label along with IMEI.
• 📦 The box is on a barcode label (but it's easy to fake!). Pay attention to the quality of the print: the original text is clear, without blurring.
• 📱 Phone Settings: Go to Settings → The phone. → General information. This is the display. IMEI, Serial number and Model.
• 🔋 Sticker under the lid SIM-The originals have a matte, microtext that's hard to read without a magnifier.

• 🔢 It consists of 14-16 characters (numbers and Latin letters).
• 📅 The first 4-6 characters often encode the date of production (e.g. 202305). = May 2023).
• 🏭 The latter symbols may indicate the manufacturer (e.g, CN — China, IN — India).

2. Check through the official Xiaomi website (global and regional)

The most reliable way is to check the serial number against Xiaomi’s database, but there are some nuances: the official service does not work for all regions, and “gray” dealers sometimes register fakes in the system.

Step 1: Checking the Global Website

1. Go to the Mi Verify page (works for global models: Mi 11, Redmi Note 10 Pro, etc.).
2. Enter. SN or IMEI check-in.
3. If the device is original, the system will show the model, activation date and warranty status.

Step 2: Checking on regional sites

• 🇨🇳 For Chinese models (Mi) 13 Ultra, Redmi K60): order.mi.com/imei
• 🇮🇳 For the Indian market: mi.com/in/verify
• 🇷🇺 For Russia: no official verification service, but you can use Mi Account (see next section).

⚠️ Warning: If a site gives an error "This device does not exist" - it does not always mean a fake:

• The device is new and not yet registered in the database (relevant for fresh models).
• SN entered with an error (check the register of letters!).
• The phone is designed for a different region (e.g., the Chinese model is checked on order.mi.com, not the global site).

3. Hidden engineering menus: check without the Internet

If you don’t have internet access or you suspect that a vendor may have “swapped” your firmware, use service codes. They work for all Xiaomis, regardless of region or version. MIUI.

Method 1. Code ##4636##

1. Open the Phone app and type ##4636##.
2. Go to the tab Information about the phone.
3. Check the lines: IMEI — The serial number -- if it's empty or if it says zero, it's fake. The build number -- the originals have the model name, ingres_global For the Redmi Note 11).

Method 2. Code *#06#

This code displays IMEI Compare it to the data on the box and in the settings. If the numbers don't match, it's either a fake or a phone with a cross-flash. IMEI (which is illegal in most countries).

Method 3. Checking through Fastboot (for advanced users)

1. Turn off the phone and press Volume Down + Power to log into the Fastboot.
2. Connect the device to the PC and type the command: fastboot getvar all
3. Find serialno and imei, which cannot be forged without physical interference with the board.

Enter the code ##4636## and check IMEI|Call *#06# and compare it to the box|Check the assembly number in "Phone Information"|Run fastboot getvar all (for experienced users)

-->

⚠️ Warning: For fakes, engineering menus are often missing or blocked, and if nothing happens after you enter the code or if there is an error, this is cause for concern.

4.Verification via Mi Account and Xiaomi Cloud

If the phone is already activated, it can be checked through a linked Mi Account, a method that is useful when buying a used device to show if the phone was blacklisted (stolen/lost).

Instructions:

1. Go to the Mi Account website and log in.
2. Go to the Devices section.
3. Find your phone on the list. It's displayed here: 📱 Model of the device 🔢 IMEI (but not a serial number!) 📅 Date of first activation

IMEI

What if the device is not displayed in your account?

• 🔄 Maybe the previous owner didn't untie the phone. → Mi Account → Get out.
• ❌ If the phone is not tied to the account at all – this is a sign of a fake or “gray” firmware.

💡 Useful tip: Before buying a used Xiaomi, ask the seller to temporarily link your Mi Account to your phone. After checking, you can untie your account. This will protect you from buying a stolen device (such phones are often blocked through the Mi Cloud).

💡

If a vendor refuses to show a linked account or settings menu, it is a red flag. The original devices do not have hidden restrictions on access to system information.

5. Signs of counterfeiting that give even the "perfect" copies

Xiaomi fakes are divided into three types:

1. Low-quality copies (easily identified by the plastic case, blurred logo).
2. "Gray" replicas (externally identical to the original, but with a simplified "iron").
3. Clones with flashing (the most dangerous - use the original board, but with a substituted one) SN/IMEI).

How to recognize a fake by the "little things":

• 🔊 The sound is dynamic: the originals have low frequencies, clear, no wheezing".
• 📸 Camera: Take a photo in HDR-Fakes often have artifacts (green/purple spots).
• 🔋 Charging: Original Xiaomi supports fast charging (e.g., fast charging, 33W For Redmi Note 12, fakes heat up and charge slowly.
• 🤖 Firmware: Go to Settings → The phone. → Version. MIUI. The original version of the shell corresponds to the model (for example, MIUI 14.0.5 for Mi 13) Fakes often have outdated or "castom" firmware.

⚠️ Warning: One of the most reliable signs of a fake is that it doesn't update. Try manually checking for updates in Settings. → The phone. → If the system says "Updates are not available" on a model that was released less than a year ago, that's a cause for suspicion.

Test for "broken" IMEI

• Enter *#06# and write it down. IMEI.
• Remove the lid. SIM-maps and compare the numbers with the sticker under the battery (if possible).
• If IMEI The phone is 100% unoriginal (possibly stolen or assembled from spare parts).

💡

Even if the serial number is checked on the official website, it does not guarantee originality. Fraudsters can register fakes in the database through gray channels. Always combine verification methods!

6. Alternative Verification Methods (for experienced users)

If you don’t trust standard methods or suspect that the data in the system is tampered with, use these techniques.
