iPhone (iOS) · System Info
View Device Information on iPhone
The About screen lists identifying and technical details about your iPhone — name, iOS version, model and serial numbers, storage capacity, and carrier information — that support staff and other apps often need.
How to open General & About
- Open Settings → General → About.
- Scroll to find Model Number, Serial Number, or IMEI as needed.
- Tap 'Name' at the top to rename the device for AirDrop and Personal Hotspot.
What you should know
- Device Name is used for AirDrop, Personal Hotspot, and Handoff, and can be renamed at any time.
- Model Number, Serial Number, and IMEI/MEID are all listed for warranty, carrier, or support purposes.
- Available storage capacity is shown alongside the total, distinct from the more detailed iPhone Storage breakdown.
- Legal and regulatory information, along with diagnostic data-sharing preferences, are accessible from this same screen.
Never share your Serial Number or IMEI publicly online, since it can be used in scam attempts to falsely report a device as lost or stolen.
Why it matters
The About screen is the fastest way to get exact, verifiable facts about your iPhone — its precise model, iOS version, and unique identifiers — which support calls, warranty claims, carrier transfers, and insurance claims all typically require. Because the device name shown here is what appears to others during AirDrop or Personal Hotspot, an unclear or default name (like 'iPhone') can make it harder to identify your device among several nearby. It's also the quickest place to confirm exactly which iOS version and model you're running before troubleshooting a problem or checking compatibility with a new accessory or app.
Best practices
- Rename your device to something recognizable but not overly personal (avoiding your full name) so it's identifiable during AirDrop without oversharing identity details in public places.
- Note down your Serial Number and Model Number somewhere safe before selling, trading in, or sending your device for repair.
- Check the exact iOS version here before searching for troubleshooting steps online, since instructions can differ meaningfully between versions.
- Review Diagnostics & Usage sharing preferences periodically if you have specific concerns about sharing crash and analytics data.
Common problems and fixes
- Carrier or support staff ask for information you can't immediately find
- Open Settings → General → About and scroll through — Model Number, Serial Number, IMEI, and carrier details are all listed together on this one screen.
- iPhone shows an unfamiliar or default name to nearby AirDrop users
- Tap 'Name' at the top of the About screen and set a clear, recognizable device name.
- Unsure which exact iPhone model you own when buying a case or screen protector
- Check the Model Number in About and cross-reference it against Apple's published model identifier list to confirm the exact device.
- Storage shown in About doesn't match what's listed under iPhone Storage
- This is expected — About shows total device capacity, while iPhone Storage reflects usable space after system reserves, so the two numbers won't match exactly.
Tips and tricks
- Tap the Model Number line to briefly reveal the raw model identifier code (like 'iPhone15,2'), which can help confirm compatibility with certain accessories or older manuals.
- Copy the Serial Number directly from the About screen with a long-press instead of retyping it manually when filling out a support or warranty form.
Frequently asked questions
Where do I find my iPhone's serial number without the physical device?
If you can't access the device, the serial number is often available in Finder or iTunes if it's ever been connected to a computer, on the original packaging, or in your Apple Account's device list.
Does renaming my iPhone affect my Apple Account or iCloud settings?
No, the device name only affects how it appears locally for features like AirDrop, Personal Hotspot, and Bluetooth pairing, and has no effect on your Apple Account itself.
Is it safe to share my iPhone's Model Number with a repair shop?
Yes, the Model Number alone is not sensitive, unlike the Serial Number or IMEI, which should be shared only with trusted parties like Apple Support or your carrier.
