How to determine the exact date of purchase of the Xiaomi device: all working methods

Why it’s important to know the exact date of Xiaomi’s purchase

The date of purchase of a smartphone, tablet or other Xiaomi gadget is not just a formality, it depends on the validity of the warranty, the possibility of free repairs, the relevance of firmware and even the market value of resale, for example, if you bought a Redmi Note 12 years ago, and the seller claims that the device is only 3 months old, this is cause for doubt.

Unfortunately, the manufacturer doesn't always specify the date of production on the box or in the settings of the device. And if you bought a gadget from hand or lost documents, it becomes even more difficult to recover information. In this article, we will analyze all the available methods, from official (via IMEI and Mi Account) to alternative (serial number analysis and support).

Spoiler: The most reliable method is to check through IMEI on Xiaomi's website, but it doesn't work for all regions. If your device is bought in Russia, China or India, the odds are high. European models may need additional steps.

Method 1: Check the date of purchase through IMEI on the official website of Xiaomi

IMEI (International Mobile Equipment Identity) is a unique 15-digit code for your device, which not only locks your smartphone when you steal it, but also tells you the date of first activation (which usually coincides with the date of purchase).

How it works: When you first turn on, the smartphone communicates with Xiaomi servers, and this information is stored.

1. Find it. IMEI: 📱 Dial on the phone keyboard *#06# - a window will appear with IMEI. 📦 Look at the sticker under the battery (for removable battery devices) or on the box. 🖥️ In settings: About the phone → General information → IMEI.

Go to the checkout site

• For global models: mi.com/global/verify.
• For Chinese versions: order.mi.com/imei (translator required).
• Enter IMEI and CAPTCHA, press "Verification".

What you will see in the results:

• 📅 Date of first activation (usually) ±1-3 days from a real purchase).
• 🌍 Region of sale (important for warranty repairs).
• ✅ Status of guarantee (valid/expired).

⚠️ Note: If the device was purchased in Europe or the United States, the service may not show the date).

Method 2: Date on the box and documents - where to look

If you have retained the original packaging or documents, the date of purchase can be found without online checks.

Important nuances:

• 📦 The date on the box is the date of production, not the date of sale.
• 🛒 If you bought from an online store (AliExpress, Wildberries, Ozone), check your order history – there is an exact date.
• 🔄 On used devices, the sticker on the box can be damaged or replaced.

💡

If the sticker on the box is erased, try to illuminate it with a flashlight at an angle - sometimes the numbers become visible.

Method 3: Checking with Mi Account (Xiaomi account)

If your device is linked to a Mi Account, you can find your activation history in your personal account, and this method works even for devices you bought a few years ago.

Instructions:

1. Open account.xiaomi.com and log in.
2. Go to the Devices section.
3. Select the desired gadget - the date of the first binding to the account will be displayed.

What to do if:

• 🔄 The device has been reset, the binding date will be updated to the current one, in which case the method will not work.
• 📱 Smartphone is not tied to the account – link it in the settings: Xiaomi Account → Add the device.
• 🌐 Chinese Account – Use the instructions for changing the region.

⚠️ Note: If you bought the device with your hands and the previous owner did not untie it from his Mi Account, the date will be shown incorrectly. IMEI-method.

Link your device to your Xiaomi | account Make sure the date and time on your smartphone are correct | Check the history in the Devices section | Compare the date to the checks (if any)

Method 4: Serial Number (S/N) Analysis – Does it Work?

The network often has instructions for decrypting the serial number (S/N) to determine the date of production, such as the first 4 digits supposedly indicate a year and a week, but in practice this method does not work for most modern Xiaomi devices (starting in 2019).

Why:

• 🔢 Xiaomi has changed the format S/N — It does not now contain a clear date.
• 📊 Even if you decrypt the number, it will be the date of production, not the sale (the difference can be up to six months).
• ⚠️ On fake devices, the serial number can be generated by accident.

If you’re wondering what the old format looks like (before 2019), here’s an example:

• 8H4BM19A05001234 – where 19A05 can mean 2019, Week 5.
• 6U8DQ18C12005678 – 18C12 = 2018, 12th week.

For new models (Redmi Note) 11/12, POCO X5, Xiaomi 13 And newer than that, it's useless. Use it better. IMEI Mi Account.

Method 5: Call for Support or Service Center

If none of these methods work, the last option is official support.

• 🔧 Gadgets with expired warranty (you need to confirm the date for repairs).
