The fastest way to find an iPhone’s serial number is to open Settings > General > About and look for Serial Number. If you no longer have the iPhone, you can still find the number through your Apple Account, a Mac or Windows PC that can see the device, or the original packaging.
If the iPhone turns on and you can unlock it, this is the simplest method. Apple lists the serial number with other device identifiers in the About screen.
Apple’s current support instructions also show IMEI, EID, and other identifiers on this page. These are different identifiers, so make sure you copy the value labeled Serial Number. See Apple’s official serial number and IMEI guide for the supported methods.
You do not necessarily need the phone in your hand. If the iPhone is still associated with your Apple Account, you can usually retrieve its device information from another signed-in Apple device or from the web.
This method is useful if the iPhone is lost, damaged, sold, or otherwise unavailable.
Apple documents this account-based method in its guide to reviewing devices signed in to your Apple Account.
If you can connect the iPhone to a computer, Apple also provides a computer-based lookup:
This is especially handy when the iPhone’s screen is difficult to use but the computer can still recognize the device.
If you kept the box, look for the barcode label on the original packaging. Apple says the label can include the serial number as well as EID and IMEI/MEID information.
One small detail can prevent transcription mistakes: Apple notes that a barcode scan may show a leading S before a product serial number, but that leading S is not part of the serial number. Apple also states that its hardware serial numbers use the digits 0 and 1, not the letters O and I. See Apple’s serial-number guidance.
Yes. On the iPhone setup screen, turn on the device and wait for the multilingual “Hello” screen. Tap the Info button in the lower-right corner to view available device identifiers before completing setup. Apple includes this method in its official iPhone serial number instructions.
| Identifier | What it identifies | Where you may see it |
|---|---|---|
| Serial number | The Apple hardware unit | Settings, Apple Account, Finder/Apple Devices, packaging |
| IMEI/MEID | The cellular device identity | Settings and, on some models, hardware or packaging |
| Model number | The iPhone model or hardware variant | Settings > General > About |
If a support form specifically asks for a serial number, enter the value labeled Serial Number, not the IMEI or model number. It is also sensible to avoid posting your serial number publicly; share it only with a service, insurer, reseller, or support channel that legitimately needs it.
