How to Find the Serial Number on Your iPhone
Every iPhone has a unique serial number — a string of letters and numbers that identifies your specific device. You might need it to check warranty status, arrange a repair, register your device, report it stolen, or verify authenticity before buying a used phone. The good news is there are several ways to find it, and most take under a minute.
Why Your iPhone Serial Number Matters
The serial number isn't just an administrative formality. Apple uses it to:
- Confirm whether your device is still under warranty or AppleCare coverage
- Identify the exact manufacturing batch and configuration of your device
- Process repair requests at Apple Stores and authorized service providers
- Verify authenticity when purchasing a refurbished or second-hand iPhone
- Support activation lock and theft reporting through tools like Apple's device checker
It's worth knowing where to find yours before you actually need it in a hurry.
Method 1: Find It in iPhone Settings 📱
This is the most reliable method and works on virtually every iPhone running a current or recent version of iOS.
- Open the Settings app
- Tap your name at the top (your Apple ID section)
- Scroll down and tap on your iPhone in the device list
- Your serial number appears on this screen
Alternatively, you can navigate directly:
- Open Settings
- Go to General
- Tap About
- Scroll down to find Serial Number
On most iPhones, you can tap and hold the serial number field to copy it — useful if you're filling out a support form or warranty check.
Method 2: Check the Physical Device
For older iPhones, or if your device won't power on, the serial number may be printed directly on the hardware.
| iPhone Model | Physical Location |
|---|---|
| iPhone 6s and earlier | Back of the device (engraved text) |
| iPhone 7 and later | Generally removed from back; check SIM tray or original box |
| Most models | SIM card tray (small engraved text) |
The text is small — you may need good lighting or a magnifying glass to read the SIM tray engraving clearly.
Method 3: Check the Original Packaging
If you still have the box your iPhone came in, the serial number is printed on a label on the outside of the box, usually alongside the IMEI and model number. This is particularly helpful for finding the serial number of a device you're setting up or one that's been factory reset.
Method 4: Use iTunes or Finder on a Computer
If your iPhone is accessible via cable but the screen is damaged or unresponsive:
On Mac (macOS Catalina and later):
- Connect your iPhone via USB
- Open Finder
- Select your iPhone in the sidebar
- The serial number appears on the summary screen — click it to reveal the IMEI and other identifiers
On Windows or older macOS:
- Connect your iPhone and open iTunes
- Click the device icon near the top left
- On the Summary tab, click where it shows your storage capacity — this cycles through the serial number, IMEI, and MEID
Method 5: Check Apple ID on the Web
If your iPhone is lost or you don't have it with you:
- Go to appleid.apple.com on any browser
- Sign in with your Apple ID
- Scroll to the Devices section
- Select your iPhone — the serial number is listed there
This works as long as your iPhone was signed into that Apple ID account.
Method 6: Check a Previous Apple Receipt or Support Case
Apple includes serial numbers in:
- Order confirmation emails from apple.com
- Repair receipts from Apple Stores or authorized service providers
- AppleCare registration confirmation emails
If you've ever had your device serviced or bought it directly from Apple, searching your email for "serial number" alongside "Apple" may surface it quickly.
Serial Number vs. IMEI: What's the Difference?
These two identifiers are related but serve different purposes.
| Identifier | What It Is | Common Use |
|---|---|---|
| Serial Number | Apple's internal device identifier | Warranty checks, Apple Support |
| IMEI | International Mobile Equipment Identity | Carrier unlocking, theft reporting, network blacklisting |
Both appear in Settings > General > About. For carrier-related issues or reporting a stolen phone to your network provider, you'll typically need the IMEI. For Apple warranty and repair processes, the serial number is what's asked for.
A Few Variables That Affect How You Access It
The method that works best for you depends on a few factors:
- iOS version — older versions have slightly different Settings menu structures, though the General > About path has remained consistent for years
- Device condition — a cracked screen or unresponsive device shifts you toward Finder, iTunes, or the Apple ID website
- Whether you're signed into iCloud — the appleid.apple.com method only works if the device was associated with your account
- Access to original packaging — straightforward if you kept the box; not helpful if you didn't
For most people with a working iPhone, Settings > General > About is the fastest route. But knowing the alternatives means you're covered even when the obvious path isn't available.
