Before you sell: the erase checklist that protects the buyer

Most “buyer locked out” stories on this site start with a seller who meant well. They erased the phone, handed it over, and only later learned that erasing alone does not remove Activation Lock. The buyer is stuck, the seller is embarrassed, and the sale turns into a dispute. This checklist takes ten minutes and prevents all of it. Order matters — do not skip to the erase step.

1. Back up, then check the backup

Back up to iCloud or a computer, then confirm the backup date. A backup you assume exists is not a backup. Check it before you erase anything, because after the erase there is no second chance.

2. Unpair your Apple Watch

If you have a Watch paired to the phone, unpair it from the Watch app on the iPhone first. Unpairing creates a fresh Watch backup and removes Activation Lock from the Watch. Erasing the phone first makes this step harder than it needs to be.

3. Sign out of your Apple Account — this is the critical step

Settings, your name, Sign Out. Enter your password when asked and choose whether to keep a copy of data on the phone (it does not matter — the phone is about to be erased anyway). Signing out turns off Find My and removes Activation Lock. Without this step, the buyer will be asked for your account at setup, and no legitimate process lets them past it.

4. Erase all content and settings

Settings, General, Transfer or Reset iPhone, Erase All Content and Settings. When the phone restarts to the Hello screen in its original language, it is ready to hand over. If it asks for your account instead, you skipped step 3 — go back and sign out properly.

5. Remove it from your trusted devices

On your new phone or at iCloud.com, check your Apple Account's device list and remove the old phone if it is still there. This is housekeeping, but it closes the loop: the old phone should no longer appear as one of your devices, receive your codes, or show up in Find My.

Frequently asked questions

Is erasing enough before selling my iPhone?

No — not on its own. You must sign out of your Apple Account first, so Activation Lock is removed. Erasing without signing out leaves the phone asking for your account, which the buyer cannot provide.

Should I unpair my Apple Watch first?

Yes. Unpairing from the iPhone backs the Watch up and removes Activation Lock from the Watch as well. If you erase the phone first, unpairing gets messier.

What if I already sold the phone without signing out?

Sign in to iCloud.com, open Find My, select the device, and choose Remove from Account. Do that as soon as you realise — the buyer cannot use the phone properly until you do.
