The activation date of a Xiaomi device is primarily determined by when it first connects to a network and registers with Xiaomi's servers. While newer MIUI/HyperOS models may display this date directly in the settings, users typically rely on official online verification tools or Google account logs to confirm the exact date. Method 1: Check via Phone Settings (MIUI/HyperOS)
2) Use the Mi Account (if the phone was signed into one)
- On the phone: Settings > Accounts > Mi Account (or visit account.mi.com and sign in).
- Look for device list or security/registration info; some accounts show the date the device was added.
The most reliable way is through Xiaomi's official product authentication system. Find your IMEI number : Open your phone dialer and enter Settings > About phone > Status Visit the official site : Go to the Xiaomi Product Authentication page Enter details
You will need your 15-digit IMEI number (or IMEI1 for dual-SIM devices): Dial Pad: Enter *#06# to display the IMEI immediately.
. Tapping this will show the date the device first connected to the network.
Enter your device’s IMEI number or Serial Number:
4) Inspect Warranty Card or Box Label
- Some Xiaomi boxes or warranty cards print the purchase or activation date, or include a stamped store date.
- The device box label may include manufacturing date and IMEI; manufacturing date is not activation date but helps judge device age.
E-Warranty: In certain regions (like India), the Xiaomi Service app comes pre-installed and features an "E-warranty card" that lists the exact date the digital warranty was triggered.
