Selling an iPhone requires erasing it first: back up, sign out of iCloud, then use Erase All Content and Settings in Settings.
A phone loaded with years of messages, photos, and logins needs a clean break before it changes hands. How to erase an iPhone before selling comes down to three actions done in the right order: preserve your data, disconnect your accounts, and trigger the factory reset that leaves the device at its Hello setup screen for the next owner. Apple’s own pre-sale guidance lays out the exact steps, and following them is the only way to avoid leaving personal data or a locked phone behind.
What Does Erasing An iPhone Actually Do?
Erasing an iPhone removes all personal content and settings and returns the device to its original out-of-box state. The process wipes photos, messages, apps, accounts, and stored credentials from local storage. It also disables Find My and the underlying Activation Lock so the next person can set up the phone with their own Apple Account. A full erase goes beyond signing out of apps or deleting a few files — it clears the device entirely and prepares it for a new owner.
Apple specifically recommends this full erase before sale, trade-in, or gift. The phone resets to factory condition and the person receiving it goes through the normal setup flow as if the device were brand new.
Erasing An iPhone For Sale: The Three-Step Process
Step 1: Back Up Your Data First
Before erasing anything, save a copy of what matters. An iCloud backup stores photos, messages, app data, and device settings in Apple’s cloud and can be restored to a new iPhone during setup. A computer backup via Finder on a Mac or the Apple Devices app on Windows saves a full device snapshot that includes data iCloud might skip, such as certain accounts and offline files.
Apple lists backup or data transfer as the very first step in its pre-sale checklist. Skipping this step means anything stored only on the phone — including notes saved locally or messages not yet synced — is gone permanently after the erase completes.
Step 2: Sign Out of iCloud and Apple Services
Signing out of your Apple Account before erasing is what disables Find My and turns off Activation Lock. Without this step, the phone stays linked to your account and the next person may see an activation screen asking for your Apple Account credentials — effectively locking them out of the device entirely.
On iOS 26 or later, open Settings, tap your name at the top, scroll down, and tap Sign Out. A menu appears with two choices: Erase this Device or Sign Out But Don’t Erase. Choosing Erase this Device removes your iCloud data from the phone as part of the sign-out process. On earlier iOS versions, the same Sign Out option appears at the bottom of the Apple Account screen without the in-line erase choice, so you proceed directly to the full device wipe afterward.
After signing out, go back to Settings > General > Transfer or Reset iPhone for the final step.
Step 3: Erase All Content and Settings
With your backup complete and your account signed out, open Settings > General > Transfer or Reset iPhone > Erase All Content and Settings. Enter your iPhone passcode when prompted, then tap Continue. If the phone asks for your Apple Account password, enter it — this confirms you own the device and want to remove it from your account for good.
After confirming, tap Erase iPhone. The phone restarts, shows a progress bar as it wipes the internal storage, and eventually lands on the Hello screen. That screen is the signal that the erase worked and the device is ready for its next owner. Do not set it back up if the goal is to sell or trade it in.
Apple’s pre-sale guidance for iPhone and iPad covers the same three steps and includes version-specific details for the sign-out options.
| Step | Action | Why It Matters For The Sale |
|---|---|---|
| 1 | Back up to iCloud or a computer | Preserves photos, messages, and settings before the wipe |
| 2 | Sign out of Apple Account in Settings | Disables Find My and Activation Lock for the next owner |
| 3 | Erase All Content and Settings | Removes all personal data and returns the phone to factory state |
| 4 | Verify the Hello screen is visible | Confirms the erase completed and the device is ready to hand over |
| 5 | Remove SIM card if keeping your line | Retains your cellular plan if not transferring it with the phone |
| 6 | Remove case and screen protector | Lets the buyer or trade-in service assess the physical condition |
| 7 | Leave the phone on the Hello screen | Next owner sets it up fresh with their own Apple Account |
The Computer Restore Method
If the on-device erase cannot complete due to a frozen screen, software issue, or if you simply prefer a wired connection, Apple’s computer restore method works as a reliable alternative. Connect the iPhone to a Mac or Windows PC using a USB or USB-C cable. On a Mac, open Finder. On Windows, open the Apple Devices app. Select your iPhone in the sidebar or device list, then click Restore iPhone. Confirm the action and wait for the process to finish.
The phone restarts, installs the latest iOS version, and arrives at the Hello screen just like the on-device method. This approach is particularly useful when the phone does not boot normally or when the on-device erase option is grayed out due to a restrictions profile or management policy.
What Are The Most Common Mistakes?
Even a straightforward erase process can go wrong in ways that leave data behind or lock the next owner out. The table below covers the errors that come up most often and how to sidestep each one.
| Mistake | Why It Creates A Problem | How To Avoid It |
|---|---|---|
| Skipping the iCloud sign-out | Leaves Activation Lock active so the buyer cannot activate the phone | Sign out in Settings > [your name] > Sign Out before erasing |
| Not backing up first | Local data disappears permanently after the wipe | Back up to iCloud or a computer before starting the erase |
| Confusing sign-out with full erase | Data remains on the phone because only the account was removed | Run Erase All Content and Settings, not just Sign Out |
| Using third-party wipe tools | Unnecessary and unsupported; Apple’s method is certified and thorough | Stick to the on-device erase or computer restore workflow |
| Interrupting the erase process | Can leave the phone in an incomplete or unusable state | Let the phone finish without unplugging or restarting it |
| Forgetting to transfer data to a new phone first | Old phone is erased before the new one is set up | Transfer data to the new device, then erase the old one |
| Stopping at the wrong screen | Phone may appear wiped but still has account data tied to it | Confirm the Hello screen shows before considering it done |
After Erasing: Confirm The Hello Screen
Once the iPhone reaches the Hello screen, the device is fully wiped and ready for its next owner. Do not set it back up — leave it at that screen so the buyer or recipient can go through setup with their own Apple Account. If the phone restarts and shows the setup language picker or the Hello screen, the erase completed successfully.
A quick visual check at this point saves trouble later: the screen should show Hello in several languages and nothing else. If instead the phone asks for a passcode or shows a locked activation screen, the sign-out step was likely skipped and the device is still tied to your account.
Three Confirmation Steps Before Handing Over The Phone
Run through this list before packaging the iPhone for sale or drop-off:
- Data is backed up — an iCloud or computer copy exists and is confirmed complete.
- Apple Account is signed out — Find My and Activation Lock are disabled and the phone no longer appears in your device list.
- Hello screen is showing — Erase All Content and Settings ran fully and the phone is at the factory-setup screen.
Any iPhone that clears these three checks is clean, unlinked from your account, and ready to sell with nothing left behind.
