Do these 3 things before closing this tab:
1Fix the driver behind crashes, sound loss and screen glitches2Clear out junk files and repair common Windows errors3Scan for outdated or missing drivers - takes under a minuteThe quickest method is on the watch: Settings → General → About → Serial Number. If the watch is unavailable but still paired, open the iPhone’s Apple Watch app and go to My Watch → General → About → Serial Number. Use the field labeled Serial Number, not IMEI.
Find the serial number on your Apple Watch
- Open Settings on the watch.
- Tap General, then About.
- Scroll until you see Serial Number.
This is the preferred route when the watch is unlocked and working. The same page may show an IMEI on GPS + Cellular models; that is a separate identifier. Menu wording can vary slightly with language, region and software version. Apple’s current instructions are at Apple Support.
Find it from the paired iPhone
- Open the Apple Watch app on the iPhone.
- Tap the My Watch tab.
- Choose General → About.
- Read or copy the value beside Serial Number.
This is useful when the watch is off your wrist, its display is damaged, its battery is empty, or you need to copy the identifier instead of reading small engraving. The iPhone must have the watch paired to it; an unrelated or unpaired iPhone will not reliably show the device.
Find the number on the watch case
Series 1 and later
Apple Watch Series 1 and newer models—including SE, Hermès, Nike and Ultra—have the physical serial number inside the band slot.

First-generation Apple Watch
On the original first-generation model, look for the engraving on the back of the case. Do not open or disassemble the watch to find an identifier. The physical locations are documented by Apple Support.
Check the original box
The barcode label on the packaging can provide the serial number and other product identifiers. This is a useful fallback if the watch is lost, will not power on, or is no longer paired, but a box can be separated from a device—especially in a second-hand sale. Compare it with a digital record, receipt or coverage result when possible.

If a barcode scan adds a leading S, leave that S out when entering the serial number. Apple also says its serial numbers use the numerals 0 and 1, rather than the letters O and I. See Apple’s serial-number guidance.
Use your Apple Account when the watch is unavailable
- Go to account.apple.com and sign in with the Apple Account associated with the watch.
- Open Devices.
- Select the Apple Watch to view the identifiers Apple makes available for that device.
This is an account-based fallback. The watch must be associated with that account, and the available details can vary with account status and Apple’s current interface.

Serial number, IMEI, model number and box code
| Identifier | What it identifies | Which watches show it | Typical use |
|---|---|---|---|
| Serial number | Apple’s identifier for an individual watch | All Apple Watch models | Support, service, coverage and records |
| IMEI | Cellular-network device identifier | GPS + Cellular models only | Cellular, carrier or some claim processes |
| Model number | Product and version identification code | Shown in device information and model-identification materials | Identifying the watch variant |
| Barcode or box code | Packaging identifier or printed representation | Original packaging | Matching the device with purchase records |
If a form asks for the serial number, enter the serial number—not the IMEI. On a cellular watch, scroll through General → About until the distinct Serial Number field appears. Apple distinguishes these fields in its watch instructions.
Check warranty or AppleCare coverage
- Open Apple’s View Coverage page.
- Enter the serial number exactly as displayed.
- Complete any verification Apple requests.
The result is intended to show coverage and AppleCare-related benefits. Availability and displayed details can depend on region, device status and Apple’s online verification flow. A coverage result is not a complete ownership, authenticity or stolen-device check, so do not treat it as conclusive proof that a used watch is safe to buy.

What the serial number is used for
- Apple Support questions and troubleshooting.
- Repairs and service appointments.
- AppleCare or coverage enquiries.
- Insurance, theft-and-loss or other claim support.
- Product registration and record updates.
- Matching a watch with its box, receipt or purchase records.
Apple notes that a serial number may be required for support and certain claim-related processes. Claim handling can involve additional steps or a third-party insurer; entering a number alone does not file or complete a claim. See Apple’s claim-support information.
If the number does not work
- Check every character and preserve the capitalization.
- Remove an accidental leading S added by a barcode scan.
- Confirm that you entered the serial number rather than the IMEI.
- Copy it from the Apple Watch app or Apple Account instead of transcribing engraving.
- Try Apple’s support or coverage page again if it requests sign-in or additional verification.
- Contact Apple Support if the identifier still fails.
A rejected lookup does not by itself prove that a watch is counterfeit or stolen; transcription mistakes, the wrong identifier, account records and Apple’s current verification process can all produce that result.

Buying or selling a used Apple Watch
Cross-check at least two independent records—for example, the watch’s digital About screen, the box, a receipt, the seller’s Apple Account record or an Apple coverage result. A matching serial number helps reconcile records, but it is not by itself proof of ownership or authenticity. Ask the seller to provide the identifier from the watch or paired iPhone rather than relying only on a loose box.
Quick Recap
Record the number safely
- Prefer copying it digitally to avoid confusing 0 with O or 1 with I.
- Keep every character intact; do not add spaces or punctuation unless a form does so automatically.
- Store it in a private password manager or personal record.
- Redact it from screenshots posted publicly unless Apple Support or another trusted service specifically needs it.
Which method should you use?
- Watch works and is unlocked: Settings → General → About.
- Watch is unavailable but paired: Apple Watch app → My Watch → General → About.
- Watch will not turn on or is unpaired: Apple Account, case engraving or original box.
- You need coverage information: retrieve the serial number, then use Apple’s View Coverage page.
