Checking your device coverage shouldn't feel like tracking down a classified file. If you're buying a used iPhone or troubleshooting a malfunctioning device, running an Apple warranty check with IMEI or serial number is the single best way to verify what you're holding. Knowing your hardware history protects you from hidden carrier locks, expired support, or stolen property.
Apple handles device authentication through specific hardware identifiers. While Apple's official portal primarily uses the device serial number for warranty status, cellular-enabled devices like iPhones also carry a 15-digit International Mobile Equipment Identity (IMEI) number. This guide breaks down how to find your identifiers, check your coverage correctly, and avoid common traps when assessing pre-owned Apple hardware.
How to Find Your Device IMEI and Serial Number
Before you can check your coverage, you need the unique code assigned to your device. iPhones and cellular iPads have both a serial number and an IMEI. Non-cellular devices like MacBooks and standard iPads rely strictly on a serial number.
Finding Your IMEI on an iPhone
You don't need to dig through menus if you know the quick shortcuts built into iOS.
- Open your phone app, dial
*#06#, and the 15-digit IMEI will appear on your screen instantly. - Navigate to Settings, tap General, and select About. Scroll down to locate your IMEI and serial number.
- Check the physical hardware. On many older models, the IMEI is etched onto the SIM tray. On newer models, it may be printed on the original retail packaging box next to the barcode.
Finding Serial Numbers on Other Apple Devices
If you are verifying a non-cellular device, use these paths:
- Mac: Click the Apple menu in the top left corner, select About This Mac, and locate the serial number listed right under the macOS version.
- Apple Watch: Open the Watch app on your paired iPhone, go to My Watch, tap General, then About.
- AirPods: Open the charging case lid and look at the underside of the lid, or check Settings, then Bluetooth, and tap the 'i' icon next to your connected AirPods.

Running the Official Apple Coverage Check
Apple provides a public portal to verify coverage and technical support eligibility. While third-party tools ask for an IMEI, Apple's native tool requires your device's serial number.
- Go to the official Apple Check Coverage Page.
- Enter your device serial number into the input field.
- Type the CAPTCHA security code displayed on the screen.
- Review the returned details, which include your hardware service coverage, repair expiration date, and telephone technical support eligibility.
If you receive an error stating that the purchase date cannot be validated, it means Apple has no record of when the device was sold retail. You can fix this by logging into your Apple account with proof of purchase or contacting Apple Support to update your device profile.
Understanding What Your Coverage Report Means
When you pull up your device record, you'll encounter specific status terms. Knowing how to interpret them prevents costly mistakes when purchasing secondhand hardware.
- Active Limited Warranty: Your device is within its initial one-year hardware warranty window. Manufacturing defects and hardware failures are covered, though accidental damage is excluded.
- AppleCare+ Active: The original owner purchased an extended protection plan. This covers accidental damage subject to service fees. Always confirm whether the plan stays with the hardware or requires transfer documentation depending on your region.
- Out of Warranty: The standard one-year window or AppleCare plan has expired. Any repairs will require out-of-pocket payment.
- Repairs and Service Coverage Expired: You can no longer get official hardware repairs through standard Apple service channels for free.
Why You Need an IMEI Check for Used iPhones
A standard warranty lookup only tells you half the story. If you're buying a phone from a private seller online, a warranty check won't reveal whether the device is paid off, blacklisted, or tied to someone else's account. That's where an IMEI check becomes essential.
Independent checker tools and carrier databases use your 15-digit IMEI to scan for red flags that Apple's portal leaves out.
- Carrier Locks: Some iPhones are restricted to a specific network carrier. If your report says "Carrier Locked," the phone will only accept SIM cards from that specific provider.
- Activation Lock Status: If Find My iPhone is enabled and tied to an active Apple account, the phone is useless if the previous owner hasn't wiped it. Never buy a device with an active iCloud lock.
- Blacklist and Stolen Status: Carriers flag IMEIs if a phone is reported lost, stolen, or associated with insurance fraud. A blacklisted phone will not connect to cellular networks for calls or data, turning an expensive smartphone into a paperweight.

Common Mistakes to Avoid
People often make avoidable errors when checking device eligibility. Keep these pitfalls in mind:
- Confusing Serial Numbers with IMEIs: Entering an IMEI into Apple's serial-only checker will yield an invalid error message. Use serial numbers for Apple's native site and IMEIs for cellular/network diagnostics.
- Trusting Screenshots from Sellers: Scammers frequently screenshot coverage pages from a completely different, working device. Always verify the serial number or IMEI directly on the physical phone screen via the settings menu.
- Ignoring Replacement Status: If a coverage report indicates that a device has been replaced by Apple, the serial number on the SIM tray or housing might not match the internal logic board if improperly repaired by a third party.
Frequently Asked Questions
Can I check an Apple warranty using only the IMEI on Apple's official website?
No. Apple's official coverage checker tool requires a device serial number. To use an IMEI, you must rely on third-party carrier and hardware diagnostic databases.
What should I do if my purchase date is incorrect on Apple's checker?
If you bought the device brand new and the date looks wrong, Apple doesn't have your sales receipt on file. Contact Apple Support with your original store receipt, and they will update the purchase date to give you your full warranty period.
Does AppleCare+ transfer to a new owner when I buy a used iPhone?
Yes, in most regions, AppleCare+ stays tied to the device hardware rather than the individual owner. As long as the device isn't reported lost or stolen, the remaining coverage transfers automatically when ownership changes.
Why does my phone show as active even though it's brand new in the box?
If an iPhone was purchased from a carrier retail store, some retail activation policies automatically trigger the warranty start date at the moment of sale or inventory scan, even if the plastic wrap hasn't been removed yet.
