The question of determining the date of purchase of a mobile device often arises when buying a used gadget, checking the warranty, or trying to find out the real age of the device. Manufacturers of smartphones based Android rarely display this information on the main settings screen explicitly, which creates additional difficulties for the user. However, there are several proven methods that allow you to identify this parameter without contacting a service center.
Knowing the exact date of activation or first sale allows you to avoid purchasing refurbished devices passed off as new, and also helps in disputes with the seller. In this article, we will analyze in detail native verification methods through the system menu, service codes and ecosystem accounts, which will help you get reliable information right in your hands.
Checking through the "About phone" menu and status logs
The most obvious, but not always obvious, way is an in-depth study of the section Settings → About phone. Depending on the version shells (MIUI, One UI, ColorOS) and version Android, the location of the information may differ radically. Some manufacturers, such as Xiaomi or Samsungsometimes duplicate information about certification or first activation in the legal sections of the menu.
Pay attention to items containing the words "Status", "Legal Information" or "Certification". In rare cases, especially in stock versions of Android on devices Google Pixel or Moto, the date of the first registration of the device may be embedded in the status logs, accessible only through special engineering menus or ADB commands, but trying to find it in the base menu is still the first step.
If the standard path does not produce results, try searching for information o warranty period. Often the system will display the warranty expiration date, from which you can mathematically subtract one year (the standard period) to arrive at an approximate purchase date. This is not always accurate, since the warranty may be extended or activated with a delay, but it gives a guideline.
⚠️ Attention: Data in the "About phone" menu can be changed programmatically when flashing the device or using custom recovery. Do not consider this information legally significant without confirmation from other sources.
If the menu indicates the end date of the warranty, subtract 12 months from it (standard warranty) to get the approximate activation date of the device.
Using service codes and the engineering menu
A more reliable method is to use hidden service codeswhich provide access to technical information about the device. Entering a combination of characters in the Phone application allows you to call up the testing menu, which often contains the first activation log or production date. The most universal code for devices on chips Qualcomm and many others is ##4636##.
After entering the code, the "Testing" menu will open. You need to go to section Information about the phone. Scroll down to the very bottom of the list. In some firmware there is a field Uptime or the date of the last reset, but sometimes you can also find the date of the first registration on the network. The interface of this menu may differ: on some devices it is a text log, on others it is a graphic table.
For devices Samsung the code often works *#12580*369#, which displays a summary table with information about the software and, in some cases, the date of build or sale. For Xiaomi the code ##6484##is useful, opening the CIT engineering menu, where in the "Version" section you can find the firmware build date, which indirectly indicates the age of the device (the purchase date cannot be earlier than the build date).
- 📞 Enter
##4636##in the dialing application to access general Android test menu. - 📅 Look for the fields "Registration date", "First boot time" or "Purchase date" in the list that opens.
- 🏭 For Samsung try
*#12580*369#, and for Xiaomi -##6484##to check the date assembly.
Analysis of Google account and synchronization data
If hardware methods do not work, let's turn to the digital footprint. The smartphone Android is inextricably linked with the account Google. The date the device was first synced to your account or the date the device was added to your trusted list can serve as an excellent marker of the time of purchase. This information is stored in the cloud and is more difficult to falsify than system logs.
Go to the security settings of your Google account through a browser or other device. Go to section Security → Your devices. Find your smartphone in the list. Often, the phrase “Last Activity” or “Added” will appear next to the model name. If the device was reset and set up again, the date may update, but if you have been using the phone since purchase without resetting, this date will be as accurate as possible.
It is also worth checking your purchase history in Google Play. Find the first free app you downloaded on this phone right out of the box. The installation date of this application will serve as a reliable indicator of when the phone was first turned on and connected to the Internet. This is especially useful if you remember that you downloaded, for example, a messenger or a game on the first day of use.
⚠️ Attention: If you performed a hard reset, the date the device was added to your Google account will be updated to the current one. In this case, the method with application installation history will be more accurate.
Checking by IMEI through official databases and warranty services
The most objective method, independent of the settings of the phone itself, is checking using a unique identifier IMEI. This number is assigned to the device at the factory and does not change when flashing. You can find out by typing the code *#06# on the call screen or by looking at the sticker under the battery (if it is removable) and on the box.
Many official websites of manufacturers (Samsung, Apple, Huawei, Xiaomi) have warranty verification pages. By entering the IMEI or serial number, the system will show the warranty status and, critically, the activation date. For most brands, the warranty activation date coincides with the date of the first sale or first registration of the device in the operator's network. The difference may be several days due to logistics, but this is the most accurate method.
There are also third-party IMEI checking services that aggregate data from various databases. They can show not only the date of sale, but also the repair history, operator blocking status (Blacklist) and the original sales region. Be careful when using paid third-party resources and give preference to official brand portals.
| Verification method | Data accuracy | Prerequisites | Risk of counterfeit |
|---|---|---|---|
| Phone settings | Low | Menu access | High (firmware) |
| Service codes | Medium | Working module communications | Average |
| Google account | High | Availability of account | Low |
| Check by IMEI | Maximum | IMEI knowledge | Minimum |
IMEI check on the manufacturer’s official website is the “gold standard” and gives the most reliable warranty activation date, close to the date purchases.
Physical markers: packaging and documents
Do not ignore analog sources of information. The original packaging of the smartphone contains a lot of useful data. A label with a barcode, IMEI and production date is usually stuck on the side or bottom of the box. The production date (Manufacturing Date) always precedes the date of purchase. If the difference between them is more than 6-12 months, there is a possibility that the phone has been in the warehouse for a long time or is a display sample.
Also check the set of documents. The warranty card, if filled out by the seller, must contain the store's stamp and the date of sale. This is the only legally significant document for service centers in the event of a breakdown. The purchase receipt (cash or electronic) is also irrefutable evidence of the date of purchase.
Inspect the device itself. The presence of micro-scratches on the charging ports, abrasions on the edges or traces of dust in the speaker may indicate that the phone was used long before it came to you. If the seller claims that the phone is “new in a sealed box”, and the production date on the box is two years ago, this is a reason for a thorough check.
What to do if the dates on the box and in the system do not match?
The discrepancy between the production date on the box and the activation date in the system is normal (the phone could be in a warehouse). However, if the date in the system (activation) is significantly earlier than the date indicated on the receipt, this is a sign of a refurbished (refurbished) device or a used product sold as new.
Specifics of different brands and shells
Different manufacturers have different approaches to storing proprietary information. Owners Samsung should pay attention to the application Samsung Members. In the "Diagnostics" or "About Phone" section inside this application, sometimes more detailed information about the status of the device and the remaining support period is displayed, which allows you to indirectly calculate the age.
Users Xiaomi (MIUI/HyperOS) can find the activation date in the service menu, but it is also worth checking the link to the Mi account. In the Mi Cloud cloud settings, the date of the first authorization is often stored. For owners OnePlus i Oppo it is important to check through the official support application, which pulls data from the company's servers by serial number.
Stock Android devices, such as Google Pixel, Motorola or Sonyare most often relied upon to be checked via IMEI on the support sites of the corresponding brands, since their system menu is maximally cleared of diagnostic data for the end user. In such cases, third-party applications from the Play Market may be useless without root access.
☑️ Algorithm of actions when buying a used phone
⚠️ Attention: Menu interfaces and Service codes may change with firmware updates. If the code does not work, try entering it without pressing the call button or check the relevance of the code for your specific model on the Internet.
Frequently asked questions (FAQ)
Can I change the date of purchase in the phone settings?
The system activation date recorded on the manufacturer’s or Google’s servers cannot be changed through normal settings. However, the date in local logs or the “About phone” menu can theoretically be changed if you have root access and edit system files, but this is difficult and requires high skills.
What to do if the IMEI on the box and the phone do not match?
This is a critical sign. Either the phone has undergone major repairs with the board replaced, or it is a device assembled from parts (Frankenstein phone), or a box from another device. It is highly not recommended to buy such a phone, as there may be problems with the warranty and blocking.
Does the code *#06# show the date of purchase?
No, the code *#06# displays only the IMEI and serial number. To obtain the date, you must use the received IMEI to check on the manufacturer's official website or in specialized services.
How to find the date of purchase if the phone does not turn on?
If the phone does not turn on, it is impossible to check the date through the settings. The only option is to find the box and documents (receipt, warranty card). You can also try checking the IMEI indicated on the box sticker on the manufacturer's website to find out the expected activation date.
Does a factory reset affect the display of the date of purchase?
A Factory Reset clears user data and can update the "last used" date in the Google account, but does not change the production date or the date of first activation of the warranty on the manufacturer's servers. Therefore, checking by IMEI remains relevant even after a reset.
