How to check if an iPhone is iCloud locked (Activation Lock)

Activation Lock is Apple's anti-theft mechanism, and it is effective. An iPhone that is still tied to a previous owner's Apple ID is, for all practical purposes, a brick. You cannot set it up, you cannot use it, and recyclers either refuse it outright or value it at nothing. Whether you are buying a used iPhone or preparing to sell one, knowing how to check for Activation Lock takes five minutes and saves a lot of grief.

This guide is specifically about iCloud / Activation Lock, which is separate from network lock (carrier SIM lock). A phone can be free of Activation Lock but still restricted to one network operator, and the reverse is also true. For network unlock checks, see our separate guide on how to check if a phone is unlocked.

What is Activation Lock and why does it matter?

Activation Lock is triggered automatically on any iPhone running iOS 7 or later when Find My iPhone is switched on. It links the device to the signed-in Apple ID at the hardware level. After a factory reset, the phone asks for that Apple ID and password before it can be activated. Without those credentials, the device will not proceed past that screen.

There is no workaround. Apple will not unlock a device without proof of original purchase. Third-party unlock services that claim otherwise are, in practice, unreliable at best and fraudulent at worst. If you buy an Activation Locked iPhone, your realistic options are: find the original owner or accept you have a very expensive paperweight.

For sellers, the situation is equally clear-cut. At Cash My Tech, we cannot accept an iPhone that is still Activation Locked. Every device is inspected before payment, and a phone tied to a previous Apple ID will fail that check. Sellers must sign out of iCloud and turn off Find My before posting their device to us.

Signs that an iPhone is Activation Locked

The most obvious sign appears on boot. If you turn on an iPhone that has been factory reset and it shows a screen reading "iPhone Locked to Owner" or similar wording, Activation Lock is active. The setup screen will ask for an Apple ID and password that you almost certainly do not know.

Other signs to watch for:

• The setup wizard gets to the Apple ID step and asks for credentials belonging to a name that is not the seller's.
• The phone appears fully set up and in use, but the seller is unwilling to demonstrate a clean erase in front of you.
• Settings shows an Apple ID signed in under someone else's name or email address.

How to check before buying a used iPhone

Apple retired its public online Activation Lock status checker several years ago. There is no longer a reliable web tool where you can paste an IMEI and get a definitive answer. On-device checking is the only dependable route.

The only reliable method: watch a clean erase in person

If you are buying face to face, ask the seller to erase the phone in front of you. The sequence is: Settings, then their name at the top, then Sign Out, then erase. After the erase completes, the phone should restart to the "Hello" setup screen and proceed through initial setup without ever asking for a previous Apple ID.

Specifically, look for this during setup:

1. The phone starts up and shows the Hello screen.
2. You select language and region.
3. You connect to Wi-Fi or skip it.
4. The phone does not ask you to enter a previous owner's Apple ID at any point.
5. You reach the "Set Up as New iPhone" option freely, with no lock screen or credential prompt blocking you.

If the phone asks for someone else's Apple ID at any point in that flow, walk away. The device is Activation Locked.

Checking a phone that is currently set up and in use

If the phone is still in the seller's hands and actively in use, go to Settings and tap their name at the top. You should see their Apple ID email address, an iCloud section, and a Find My section. What matters is that the account shown belongs to the person in front of you, and that they can demonstrate signing out on the spot. A seller who hesitates to do this is a red flag.

You can also ask the seller to show you Settings, then General, then About. The serial number shown there can be used to verify warranty status on Apple's website (checkcoverage.apple.com), which at minimum confirms the device is a genuine Apple product registered with Apple.

Buying remotely

Remote purchases carry more risk. At minimum, ask the seller to photograph the Settings screen showing their Apple ID, and to photograph the device at the Hello screen after erasing. Video of the erase process is even better. If a seller will not provide this, treat it as a locked device until proven otherwise.

What sellers must do before selling

If you are selling your iPhone and want to avoid any delays or payment holds, the steps are straightforward. You need to turn off Find My, sign out of your Apple ID, and then erase the device. The full step-by-step walkthrough is in our guide on how to sign out of iCloud before selling your iPhone.

In brief:

1. Go to Settings and tap your name.
2. Tap Find My, then Find My iPhone, and toggle it off. Enter your Apple ID password to confirm.
3. Go back to Settings, tap your name, scroll to the bottom, and tap Sign Out.
4. Once signed out, go to Settings, General, Transfer or Reset iPhone, and tap Erase All Content and Settings.
5. After the erase, the phone shows the Hello screen with no Apple ID linked to it.

Do this before you post the phone. We cannot remove your Apple ID remotely, and a device that arrives still Activation Locked cannot be processed until the original owner clears it.

Already stuck with a locked iPhone?

If you have already received an Activation Locked device and cannot return it, your options are limited.

• Contact the original owner. Only the person whose Apple ID the phone is linked to can remove Activation Lock. If you bought from a private seller, reach back out. If they can log in to appleid.apple.com and remove the device from their account, the lock clears without the phone needing to be physically present.
• Contact Apple Support. Apple may assist in certain circumstances, such as a deceased owner, but they require documentation and the process is not guaranteed.
• No other realistic options exist. Any service advertising a guaranteed Activation Lock removal for a fee is almost certainly a scam.
