Finding your Apple device's serial number doesn't require digging through dusty manuals or guessing codes. Whether your screen works, your Mac turns on, or your iPhone is powered down, you can locate this unique identifier in minutes using system menus, physical engravings, or your Apple account.
Every Apple product carries a distinct alphanumeric string that proves ownership, verifies warranty status, and helps technicians process repairs. If you're trying to track down this number for an iPhone, Mac, iPad, Apple Watch, or AirPods, skip the guesswork and use these direct paths.
Find Your Serial Number on iPhone, iPad, and iPod Touch
The quickest path to your mobile device's serial number is through the built-in software settings.
- Open the Settings app on your device.
- Tap General, then select About.
- Look for Serial Number in the list. You can touch and hold the text to copy it directly into a support form.
If your screen is unresponsive or your device won't boot past the setup screen, you still have options. On newer models, you can find the IMEI or MEID printed directly on the SIM tray. If the device is sitting at the initial "Hello" welcome screen, tap the small Info button (the letter 'i' inside a circle) in the bottom-right corner to reveal hardware identifiers without completing setup.
For older hardware, check the back aluminum casing, where Apple traditionally engraved the model details and serial digits.
Locate Serial Numbers for MacBooks, iMacs, and Mac Studios
Desktop and laptop Macs offer multiple physical and digital routes depending on whether you're currently logged into the operating system.
Via System Settings
If your Mac boots up normally, click the Apple icon in the top-left corner of your screen and select About This Mac. A window opens instantly displaying your exact hardware specifications and serial number.
Using Terminal
If you prefer keyboard shortcuts or need to pull text programmatically, open the Terminal app from your Applications folder or via Spotlight search. Type the following command and press Enter:
system_profiler SPHardwareDataType | grep Serial
Your hardware serial number populates immediately on the next line.
Physical Inspections
If your Mac won't turn on, flip it over. Apple prints or laser-etches serial numbers on the bottom case of MacBooks near the regulatory text. For desktop units like the Mac mini or Mac Pro, check the bottom plate or the rear port housing.
Uncover Serial Numbers for Apple Watch and AirPods
Smaller accessories lack display menus deep enough for standard text entry, requiring specific navigation paths.
- Apple Watch: Open the Settings app on your watch, tap General, then select About to view your serial number. Alternatively, open the Watch app on your paired iPhone, go to the My Watch tab, and tap General > About.
- Standard AirPods: Open the charging case lid. The serial number is printed clearly on the underside of the lid.
- AirPods Max: Remove the magnetic left ear cushion. The serial number is printed on the aluminum chassis underneath the pad.
Find Serial Numbers Without Physical Access
If your device was lost, stolen, or broken beyond repair, you can still retrieve its serial number through alternative Apple ecosystem records.
Check Your Apple Account Online
Log into your account page at Apple Account using a web browser. Scroll down to the Devices section and click on your missing device to view its serial number, IMEI, and hardware model.
Use a Secondary Apple Device
If you own another Apple product—such as an iPad—that shares your primary account, open Settings and tap your name at the top. Scroll down past your profile details to review every trusted device linked to your account, then tap an item to check its serial number.
Inspect Original Packaging
If you kept the original retail box, look at the exterior barcode sticker. Apple prints the serial number directly beside a barcode labeled with a capital "S".

Common Mistakes to Avoid
- Confusing letters and numbers: Apple intentionally avoids using the letter 'O' and the letter 'I' in serial strings to prevent confusion with the digits zero ('0') and one ('1'). If a typed code fails, double-check those specific characters.
- Including prefix letters: Barcode scans on retail boxes often prepend a leading 'S' character. This letter is a formatting flag for the scanner, not part of your actual hardware serial string.
- Assuming all models match: Don't assume a method for an iPhone applies identically to an iPad or Mac. Always verify your specific device category before tearing down hardware or hunting through settings menus.
Frequently Asked Questions
What does an Apple serial number look like?
Most modern Apple serial numbers consist of a 12-character alphanumeric string. Older legacy devices may use shorter 10-character formats. The sequence encodes manufacturing location codes, production dates, unique identifiers, and model specifications.
Can someone steal my device using its serial number?
No. Unlike an IMEI number on a cellular phone, which interacts with carrier networks, a serial number alone cannot be used by unauthorized parties to track your location, lock your device, or access your personal data.
What should I do if my serial number won't scan?
If digital entry fails or a support form rejects your characters, try typing the string manually. Pay close attention to zeroes versus uppercase letters. If the hardware is damaged, check your original purchase invoice or contact the retail vendor where you bought the product.
Does Apple Care require a serial number?
Yes. When you register a device or file a hardware repair claim, Apple support relies on the serial number to verify coverage eligibility, check warranty expiration dates, and ship replacement parts.
