Where to Find iPhone Serial Number Finding your iPhone's serial number is straightforward and essential for warranty checks, support, or verifying authenticity—especially with the latest iPhone 16 series making headlines in early 2026 for their advanced A18 chips and repair-friendly designs. Apple's official guidance, updated as recently as December 2025, emphasizes quick methods that work across all models, from the original iPhone to current ones.

Primary Method: Via Settings App The fastest way, recommended by Apple Support, is through your iPhone's built-in Settings—no extra tools needed.

  • Open the Settings app (gray gear icon).
  • Tap General , then About.
  • Scroll to find Serial Number (a 12-character code like "F7KX123ABC45"). Tap and hold to copy it for easy sharing.

This works on every iPhone, including eSIM-only models like iPhone 14 and later, and takes under 30 seconds.

If Your iPhone Isn't Handy: Remote Options Lost your phone or buying used? No problem—here are reliable alternatives pulled from Apple's docs and user- tested tips.

Method| Steps| Best For| Notes 15
---|---|---|---
Apple ID Account| Go to appleid.apple.com, sign in, select Devices > your iPhone.| Remote access, lost/stolen phones| Lists serial, IMEI too.
Original Packaging| Check the barcode label on the box (upright orientation).| Buying/selling used devices| Matches device exactly.
Computer Connection| Connect to Mac (Finder) or PC (Apple Devices/iTunes), select device.| Detailed info with IMEI/EID| macOS Catalina+ uses Finder.
SIM Tray (Older Models)| Eject tray; engraving on back (iPhone 6s or earlier).| Physical inspection| Not on newer models.

Dial *#06# in the Phone app for IMEI (related but distinct from serial).

Pro Tips from Forums & Trends Recent Reddit threads and YouTube guides (like those from late 2025) highlight using serial to check if it's new (starts with "M"), refurbished ("F"), or replacement ("N") via Settings > About > Model Number. For warranty, visit checkcoverage.apple.com—enter the serial to see expiration dates, a hot topic amid 2026's rising refurbished market. Bold highlight : Always cross-verify with Apple's site to avoid scams, as forum users warn about fake serials in secondhand sales.

TL;DR at Bottom
Easiest: Settings > General > About. Remote: Apple ID or box. Verify warranty online.
