How to Check if an iPhone is Original (2026 Guide)

Buying an iPhone is a significant investment, so it's important to verify that the device is genuine before making a purchase. Whether you're buying a brand-new or used iPhone in Sri Lanka, checking its authenticity can help you avoid counterfeit devices, refurbished phones sold as new, or stolen devices.

This guide explains the most reliable ways to confirm that an iPhone is original before you buy.

Quick Checklist

Check How to Verify Recommended
IMEI Number Matches the device and SIM tray ✅ Yes
Serial Number Check on Apple's website ✅ Yes
Activation Lock Must be removed by previous owner ✅ Yes
Parts & Service History Check for replaced parts ✅ Yes
Face ID Should work perfectly ✅ Yes
True Tone Should be available ✅ Yes
Battery Health Check battery condition ✅ Yes

1. Check the IMEI Number

Every original iPhone has a unique IMEI number.

To view the IMEI:

  • Open Settings → General → About
  • Scroll down to IMEI
  • Dial *#06#

The IMEI should match the number printed on the SIM tray (on supported models), original box, and purchase invoice if available.

2. Verify the Serial Number

Go to:

Settings → General → About

Find the Serial Number and verify it using Apple's official warranty and coverage checker.

A genuine iPhone will display its correct model information, warranty status, and activation details.

3. Check Activation Lock

Activation Lock protects stolen iPhones.

  • Erase the phone if buying used.
  • During setup, it should not ask for the previous owner's Apple Account.
  • If it does, do not purchase the device until the owner removes it.

4. Check Parts & Service History

Apple allows users to see whether important components have been replaced.

Settings → General → About → Parts & Service History

You may see:

  • Genuine Apple Part
  • Unknown Part
  • No Parts Replaced

Phones showing "Unknown Part" for the display, battery, or camera may have been repaired using non-genuine components.

5. Test Face ID

Go to:

Settings → Face ID & Passcode

  • Set up Face ID.
  • Lock and unlock the phone.
  • Face ID should work instantly.

If Face ID is unavailable or not working, the device may have suffered damage or undergone unauthorised repairs.

6. Check True Tone

Original Apple displays support True Tone.

Go to:

Settings → Display & Brightness

If True Tone is missing unexpectedly, the display may have been replaced or repaired improperly.

7. Check Battery Health

Navigate to:

Settings → Battery → Battery Health & Charging

Look for:

  • Maximum Capacity
  • Peak Performance Capability
  • Battery Condition

A battery health above 85% is generally a good sign for a used iPhone.

8. Inspect the Physical Condition

  • Check for original screws.
  • Ensure the display sits flush with the frame.
  • Inspect cameras for dust or moisture.
  • Test all buttons.
  • Check speakers and microphones.
  • Verify the charging port functions properly.

9. Test Essential Features

  • Wi-Fi
  • Bluetooth
  • Mobile network
  • GPS
  • Cameras
  • Flash
  • Speakers
  • Microphones
  • Touchscreen responsiveness

Warning Signs

  • Price is unusually low.
  • No serial number available.
  • Activation Lock enabled.
  • Face ID not working.
  • Unknown parts installed.
  • Battery health is extremely low.
  • Seller refuses testing.

Buying Tips for Sri Lanka

  • Buy from authorised or trusted retailers.
  • Always request the original invoice if available.
  • Check the IMEI and serial number before paying.
  • Meet in a safe public place when buying privately.
  • Test every major feature before completing the purchase.

Final Verdict

Checking an iPhone's originality only takes a few minutes but can save you from costly mistakes. Verify the IMEI, serial number, Activation Lock, battery health, and parts history before buying. Whether you're purchasing a brand-new or used iPhone in Sri Lanka, these checks will help ensure you're getting a genuine Apple device in good condition.
