iPhone warranty and activation date, explained
A 'brand new, sealed' iPhone can have been activated a year ago. A 'six months old' phone can be out of warranty. The activation date is the one fact that does not lie, and Apple's own records will tell you it for free.
When Apple's warranty starts
Apple's one-year limited warranty begins on the date the device is first activated — the first time it is set up on a network — not the day it was bought. AppleCare+ extends that coverage and is tied to the same date. A phone that sat in a shop for months still gets a full year from activation.
Check the activation date
The free activation date check returns the first activation date, the last restore date and the next tether policy. If a seller's story and the activation date disagree, believe the date.
Check the warranty itself
The free Apple warranty check shows whether the device is still covered, until when, and whether it has AppleCare+. It works by serial number or IMEI for iPhone, iPad, Mac and Apple Watch.
What a refurbished or replaced phone shows
An Apple-replaced unit (from a warranty swap) carries the remaining coverage of the original. A third-party refurbished phone shows its original activation date, often years back, and usually no coverage. The full info check puts model, coverage and dates on one screen.

Questions people ask
Does the warranty transfer to the new owner?
Yes. Apple's warranty and AppleCare+ follow the device, not the buyer.
Why does a new iPhone show an activation date in the past?
It was activated before — by a previous owner, by the shop for a demo, or during a return. It is not new.
Can I check a Mac or Apple Watch warranty here?
Yes. Any Apple device answers to its serial number.
Is the activation date the same as the purchase date?
No. Purchase is when money changed hands; activation is when the device first connected. Apple counts from activation.
