To find the serial number on your iPhone, you have several options depending on whether the device is on, off, or accessible:

If your iPhone is turned on and set up:

• Open the Settings app.
• Tap General.
• Tap About.
• Look for the Serial Number listed on this page. You can tap and hold the serial number to copy it if needed

If your iPhone is not set up yet:

• Turn on the device.
• On the initial "Hello" screen, tap the small info icon (ⓘ) in the bottom-right corner.
• The serial number will be displayed along with other device information

If you cannot turn on your iPhone:

• Check the original packaging box; the serial number is printed on the barcode label on the box

• Log into your Apple ID account at appleid.apple.com, then scroll down to Devices , select your iPhone, and view its serial number there

• If you have another Apple device signed in with the same Apple ID, open Settings on that device, tap your name, scroll to the list of devices, select your iPhone, and see the serial number

For older iPhone models:

• The serial number may be engraved on the back of the device or printed on the SIM card tray, depending on the model

These methods cover all typical scenarios for locating your iPhone's serial number
