Owning a modern smartphone from the Xiaomi brand or its sub-brands, such as Redmi and POCO, requires careful attention to warranty obligations. Often owners are faced with the need to confirm the purchase of a device for maintenance, but can not find a paper check. Fortunately, there are several reliable ways to recover this information using digital traces left by the device itself.
The relevance of this topic is dictated by the fact that the official warranty period is calculated from the date of purchase specified in the check, not from the date of production or activation. If you lose the purchase document, knowing the exact date can be a decisive factor when contacting an authorized service center. In this article, we will discuss all available methods, from simple visual checks to the use of system codes.
Search for information in the system settings of the smartphone
The most obvious, but not always working, method is to check the About Phone menu. In newer versions of the MIUI and HyperOS shell, developers often hide the exact date of activation or sale, leaving only the date of production. However, in some regions and on certain models, this information is still available for viewing without using third-party utilities.
To start the check, you need to go to Settings → About Phone → All settings. Here you should carefully examine the list of characteristics. If you are lucky, you will see a line “Purchase Date” or “Activation Date”; otherwise, it will only show the production date, which may differ from the purchase date by several months, which is critical for warranty service.
It is worth noting that the availability of this information on the menu depends on the policy of the distributor and the firmware version. Global versions of software often do not have this feature, while Chinese builds may contain more detailed data. If the menu is empty, do not despair - there are deeper methods of verification.
⚠️ Note: The production date on the box or in the settings does not constitute legal proof of the start of the warranty period.The service center has the right to count the warranty from the production date if you do not provide a check, which may reduce the support period for the production date. 3-6 months.
Verification through Mi Account and Cloud Services
If you have used your Mi Account since the first day of your device’s turn on, it could have been stored in the company’s cloud, which is one of the most reliable ways, since linking the device to the account often fixes the activation time stamp. To verify, you must log in to the official Mi Cloud website or through the Security app on another Xiaomi device.
Once you go to the device management section, you can see a list of all the gadgets that have ever been connected to your profile. By getting stuck your cursor or clicking on a particular model, you can sometimes see detailed information, including the approximate time of first sync, which often coincides with the time of initial setup of the smartphone after purchase.
- 📱 Go to the Settings menu → Mi Account on the phone itself.
- 🌐 Log in to cloud.mi.com via your browser on your computer.
- 🔍 Find the Devices section and select your smartphone from the list.
- 📅 Check the date of the first entry in the synchronization or activation log.
It is important to understand that this method only works if you have not performed a full reset (Wipe Data) with the deletion of the account before checking. If the device was reset and re-linked, the date can be updated, in which case it is better to use the check on the unique IMEI identifier.
Use of box code and factory marking
The physical packaging of a smartphone is a storehouse of information that many users throw away immediately after unpacking. There is always a barcode sticker on the end of the box with basic information. In addition to IMEI and serial number (SN), it often specifies the date of production in the format of GGMM (year and month).
Although the date of manufacture is not the same as the date of purchase, it gives an upper age limit for the device. Knowing that the phone could not have been purchased before it was manufactured, you can argue your position in the service center. For example, if the box is the date 05/23 (May 2023), and you bought the phone in June 2023, then the absence of a check will not be fatal, since the warranty period is still valid.
In addition, some boxes, especially those intended for CIS markets, may have additional markings from the importer with the date of importation of the lot, which is an indirect confirmation that the device was on sale at a certain period.

Take a quality photo of the sticker from the back of the box immediately after you buy it and save it in cloud storage.This will replace the lost check in many situations.
Requesting data from the seller through the online office
In the digital age, paper checks are becoming a thing of the past, giving way to electronic counterparts, and if you bought a smartphone from a large network store or on an official marketplace, you have a high chance of recovering your purchase information through a customer’s personal account, whether it’s retailers like M. Video, DNS, Citilink, or sites like Ozon and Wildberries.
You need to log into your account on the store's website, find the "My Orders" or "Shopping Archive" section, which stores a complete transaction history with exact dates, amounts and lists of goods, you can re-download the check or statement, which will be legally valid on a par with the original paper, the electronic check contains all the necessary details for the warranty event.
If the order was made a long time ago and does not appear in the main list, try using a history search or contact the store's technical support service, calling the phone number to which the account was registered. Operators often have access to archives for the last time. 3-5 years.
⚠️ Note: When buying from hand (on Avito or from friends), it is almost impossible to restore a clear date of purchase through the store if the first owner did not keep the documents.
Analysis of IMEI and serial number on official resources
The most technically accurate way is to verify the unique IMEI (International Mobile Equipment Identity) identifier, which is assigned to each phone during production and contains encoded model and batch information. To begin the check, you need to know your IMEI by dialing *#06# in the phone app.
The resulting code can be entered on specialized aggregator sites or on the official Xiaomi warranty verification portal, the system will give the status of the device whether it is activated or not, as well as an approximate date of first registration on the network. Although the exact date of purchase may not be displayed there, the activation date often serves as a starting point for the countdown of the warranty period in authorized centers.
There are many online services that show more detailed information on IMEI, including color, memory and region of release, but be careful and use only proven resources to avoid passing your data to fraudsters.
☑️ Verification of the status of the guarantee
IMEI results may vary depending on the region for which the device is released. Global (Global) and Chinese (CN) versions are verified through different databases. If the phone is grey (introduced by parallel imports), warranty information may not be available in your country, even if it is still valid in the country of origin.
Comparison of methods and confidence table
Each of these methods has its advantages and limitations. To choose the best option, you need to understand what information you are looking for: a legal date for the court and service or just curiosity about the age of the gadget.
| Method of verification | Accuracy of date | Conditions required | Legal force |
|---|---|---|---|
| Electronic check | 100% (Exact date) | Access to an email or store account | Tall. |
| Phone settings | Average (Date of activation) | Internet and Mi Account availability | Low. |
| IMEI check | Average (Date of first registration) | Working modem and network | Medium |
| Marking on the box | Low (Date of production) | Preserved packaging | Absent. |
As you can see from the table, the most reliable source is an email check or bank statement confirming a transaction, all other methods provide only indirect data that can be used by the service center only if you are loyal to the customer or as an additional argument.
What to do if no one method helps
The situation of a check lost, an account deleted and a box thrown away is complex, but not hopeless, in which case consumer protection legislation comes into effect, which often allows for the use of witness statements or bank statements (if the payment was by card) as proof of purchase.
You can contact the bank through which the payment was made and request an archived statement of the movement of funds for a specific date, the purpose of payment often indicates the store and sometimes even the check number or product model, this document, certified with the bank's seal, Xiaomi service centers accept on a par with the cashier's check.
Can I get my check back in the tax office?
It is also worth trying to contact the store, even if you do not remember the exact date. If you paid with the loyalty card of this store or the phone number was recorded when you bought, the operator can find the transaction through the customer database. Always keep digital copies of important documents to avoid similar problems in the future.
