Buying a used or second-hand iPhone is common, but it’s important to know whether the device is brand new, officially refurbished by Apple, or a replacement unit. Apple Certified Refurbished iPhones are high quality, but non-Apple refurbished ones may have issues.
Here’s how to easily check if your iPhone is refurbished.

1. Check the Model Number (Fastest & Most Reliable Method)
This is the best official indicator.
- Open the Settings app.
- Tap General.
- Tap About.
- Look for Model Number (tap it once if it shows the storage capacity — it will expand to the full model number).
Decode the First Letter:
- M → Brand new iPhone (originally sold as new by Apple or authorized seller).
- F → Refurbished by Apple (Apple Certified Refurbished).
- N → Replacement unit (Apple replaced the original device under warranty).
- P → Personalized (engraved) device.
If the model number starts with F, the iPhone is officially refurbished.
2. Check Warranty and Purchase Date on Apple’s Website
- Go to Settings → General → About and note the Serial Number.
- Open any browser and visit: checkcoverage.apple.com
- Enter the Serial Number and complete the verification.
- The website will show:
- Purchase date
- Warranty status
- Whether the device is still covered
A very recent purchase date on a “used” phone or mismatched information can indicate it is refurbished or second-hand.
3. Physical and Visual Inspection
- Build Quality: Genuine new iPhones have perfect finishing. Look for scratches, glue marks, or uneven gaps around the screen and buttons.
- Screen: Check for micro-scratches or yellowish tint (common on some refurbished screens).
- Battery Health:
- Go to Settings → Battery → Battery Health & Charging.
- New iPhones usually show 100% Maximum Capacity with low cycle count.
- Refurbished ones may have slightly lower capacity even if recently replaced.
- Accessories: Original packaging, cables, and charger should match Apple standards. Cheap or mismatched accessories are a red flag.
4. Other Verification Methods
- Activation Lock & iCloud: Make sure the iPhone is properly reset and not linked to someone else’s Apple ID.
- Apple Store App: If you have the Apple Store app, check your devices section — refurbished units may show special indicators.
- IMEI Check: Use websites like imei.info or your carrier’s IMEI checker to see the device history (blacklist status, original carrier).
- Performance Test: Run benchmarks or observe heating, charging speed, and camera quality. Refurbished phones from non-Apple sources may underperform.
5. Buying Tips to Avoid Fake Refurbished iPhones
- Buy from Apple’s Official Refurbished Store, authorized resellers, or trusted platforms with return policies.
- Always ask for the original invoice and box.
- Prefer devices with remaining Apple warranty.
- Avoid deals that seem “too good to be true.”
- For second-hand purchases, meet in person and test thoroughly.
Common Signs of Non-Apple Refurbished iPhones
- Model number starts with F but sold as “new.”
- Low price with poor packaging.
- High battery cycle count on a “new” phone.
- Unusual software glitches or heating issues.
- Missing original accessories.
Conclusion
The simplest way to check if your iPhone is refurbished is by looking at the Model Number in Settings → General → About. A model starting with F confirms it is Apple-refurbished, while M means it was originally sold as new.
Always combine multiple checks — model number, serial number on Apple’s website, physical inspection, and battery health — for complete confidence. Knowing this information protects you from overpaying or buying low-quality devices.
