Note (October 2026): This article originally sent readers to an online IMEI checker, but Apple removed that iCloud.com tool in January 2017 and Justwebworld has never offered its own checker. The steps below now follow Apple’s current on-device check.
To check the iCloud Activation Lock status of a used iPhone or iPad, turn the device on. On iOS or iPadOS 15 or later, a locked device shows an “iPhone Locked to Owner” screen. If you instead see a passcode Lock Screen or Home Screen, it has not been erased; if setup asks for the previous owner’s Apple Account, it is still linked. The device is ready only when the Hello screen appears.
Key Takeaways
- Activation Lock is part of Apple’s Find My feature and turns on automatically when Find My is turned on.
- Apple removed its public online Activation Lock checker (which accepted an IMEI or serial number) in late January 2017, so the check is now done on the device itself.
- A used iPhone or iPad is ready to use only when it shows the Hello screen and never asks for the previous owner’s Apple Account.
- Sellers should sign out of their Apple Account and use Erase All Content and Settings; according to Apple, erasing the device turns off Find My and Activation Lock.
- If you are locked out of a device you own, Apple accepts an Activation Lock support request when you have proof of purchase.
Please remember, if you intend to buy a used iPhone or iPad (or an older iPod touch, a line Apple discontinued on May 10, 2022), you have to check the iCloud activation lock status of the device and see if this option is activated. Knowing this info will save you a lot of time and troubles.
If you are wondering why it is important to check the Activation lock status of the device and why exactly this applies only to users of Apple gadgets, then do not worry, we will explain all that you need to know in detail.
iCloud Activation Lock Status (iCloud Checker)
The iCloud Activation lock status is part of Apple’s Find My feature: it is designed to prevent anyone else from using an iPhone or iPad that is lost or stolen, because the owner’s Apple Account password is required before the device can be erased or reactivated. Find My also lets the owner mark a device as lost, which locks the screen with a passcode and shows a custom message, and in the most extreme cases erase the device remotely.
A remote erase is a last resort, but according to Apple, Activation Lock continues to deter anyone from reactivating the device even after it has been erased remotely.
Why it is important to know the Activation lock status of the iOS device?
There are several reasons to check the iCloud Activation Lock status of any used Apple device before you buy it. The most important one is that the lock is designed to stop anyone except the account owner from using the device.
If you buy an Apple device and the “Find my iPhone” feature (now part of the Find My app) is still on, then after the iPhone is erased the setup process will ask for the previous owner’s Apple Account (formerly called Apple ID) and password.
Unless the previous owner enters that password or removes the device from their account, you will not be able to finish setup or use the iPhone. Apple’s advice is to hand the device back to the seller so they can enter their password, or to ask them to remove it from their account.
Justwebworld does not offer an Activation Lock checker tool, and Apple removed its own public online checker on iCloud.com in late January 2017. The reliable check today is the on-device method Apple describes, explained below.
How to see the iPhone activation lock status
Until January 2017, buyers could check online whether the Find my iPhone security option was enabled. The old method (no longer available) worked like this:
- The buyer opened Apple’s Activation Lock checker page on iCloud.com in a web browser.
- That page showed the iCloud activation checker interface; it has returned a “Not Found” error since late January 2017.
- The buyer entered the IMEI or serial number of the iPhone, iPad or iPod touch to see whether the feature was enabled or disabled.
- The page then asked for a captcha verification code.
- After pressing Continue, the status appeared on screen. For the method that works now, see the on-device check below.
One more point applies to sellers. Before you pass an iOS device to a new user, sign out of your Apple Account and erase the device; according to Apple, erasing an iPhone or iPad with Erase All Content and Settings turns off Find My and Activation Lock. While you own the device, keep Find My, and therefore Activation Lock, turned on, because it protects the device and your data if it is lost or stolen.
If a device you already own is locked, the legitimate route is Apple’s own process: sign in with the Apple Account used to set it up, or start an Activation Lock support request with proof of purchase. Checking whether Activation Lock is on before you pay is strongly recommended for anyone buying an iOS device from a second-hand seller, and the on-device check below is the way to do it. 🙂
How Do You Check Activation Lock on a Used iPhone or iPad Today?
Apple’s current guidance is to check the device in person before you pay, because there is no longer a public online checker. Apple applies this advice to any iPhone or iPad bought from someone other than Apple or an Apple Authorized Reseller.
- Turn on or wake the device. On iOS or iPadOS 15 or later, a device protected by Activation Lock shows an “iPhone Locked to Owner” screen. Apple says not to take ownership of a device that shows it.
- Unlock the device. If the passcode Lock Screen or the Home Screen appears, the device has not been erased. Ask the seller to erase it completely before you take it.
- Begin setup. If setup asks for the previous owner’s Apple Account information, the device is still linked to their account. Hand it back so the seller can enter their password.
- If the seller is not present, contact them and ask them to remove the device from their account using a web browser.
- Look for the Hello screen. According to Apple, a device is ready for you to use when you see the Hello screen.

Online IMEI Checker vs On-Device Check
| Method | Status as of October 2026 | What it needed |
|---|---|---|
| Apple’s Activation Lock page on iCloud.com | Removed in late January 2017 (it became available in October 2014) | IMEI or serial number of an iPhone, iPad or iPod touch |
| “iPhone Locked to Owner” screen | Current, on iOS or iPadOS 15 or later | Turning on or waking the device |
| Setup process check | Current | Starting setup and watching for a request for the previous owner’s Apple Account |
What Should a Seller Do Before Handing Over an iPhone?
Apple’s support guide lists these steps for an iPhone or iPad running iOS 26 or later:
- Back up the device, and unpair any Apple Watch that was paired with the iPhone.
- Open Settings, tap your name, scroll down and tap Sign Out, then choose to erase the device or sign out without erasing. If asked, tap Sign out of iCloud and Store.
- Go to Settings, then General, then Transfer or Reset iPhone, and tap Erase All Content and Settings. Enter the device passcode if asked, then tap Erase.
- If the device uses an eSIM, choose to erase the eSIM profile as well.
- Remove the old device from your list of trusted devices.
On iOS 18 or earlier, the Sign Out step asks for the Apple Account password and a tap on Turn Off. Apple also notes that you should check Parts and Service History for any “Finish Repair” message before a trade-in. Sellers who no longer know their password can follow this guide on how to reset an iCloud password.
What If the Device Is Still Locked After You Bought It?
Apple documents three legitimate ways to remove Activation Lock:
- Enter the original credentials: the Apple Account and password, or the device passcode, used to set up the device.
- Remove it on the web: the previous owner signs in at iCloud.com/find, selects the device and chooses Remove This Device. Apple says this works for offline devices, and for an iPhone it may work even when the phone is not offline.
- Start an Activation Lock support request: Apple accepts these from people who have proof of purchase documentation.
Devices owned by a business or school are handled by that organization’s IT department. Apple’s documentation does not list any third-party “iCloud unlock” service among these routes, so offers of that kind should be treated with caution.
Which Apple Devices Use Activation Lock?
| Device | Activation Lock requirement (per Apple) |
|---|---|
| iPhone and iPad | Turns on automatically with Find My |
| Apple Watch | watchOS 2 or later |
| Mac | macOS Catalina or later, on a Mac with the Apple T2 Security Chip or Apple silicon |
| Apple Vision Pro | visionOS |
According to Apple, each time an iPhone or iPad is activated or recovered, it contacts Apple to check whether Activation Lock is on. The lock can also protect individual parts: a previously used part taken from a device that was protected by Activation Lock is ineligible for service under the Apple Limited Warranty or an AppleCare plan. That is one more reason to buy from reputable sellers, as covered in this guide to buying second-hand tech on eBay, and to review the wider iPhone security guide once the device is yours.
Frequently Asked Questions
Can I still check iCloud Activation Lock status with an IMEI number?
Not through Apple. Apple’s public checker on iCloud.com, which accepted an IMEI or serial number, was removed in late January 2017. Apple’s current guidance is to check the device itself: look for the “iPhone Locked to Owner” screen and make sure setup reaches the Hello screen.
What does “iPhone Locked to Owner” mean?
The “iPhone Locked to Owner” screen means the device is protected by Activation Lock and is still linked to someone’s Apple Account. Apple advises buyers not to take ownership of any used iPhone or iPad that shows this screen.
Does erasing an iPhone remove Activation Lock?
Erasing an iPhone with Erase All Content and Settings on the device turns off Find My and Activation Lock, according to Apple, though the owner may need to enter their Apple Account password. A remote erase through Find My is different: the device stays activation locked afterward.
Can Apple remove Activation Lock for me?
Apple accepts an Activation Lock support request if you have proof of purchase documentation for the device. Otherwise, the lock has to be removed by the account owner, either on the device or at iCloud.com/find.
Is Activation Lock the same as Find My iPhone?
Activation Lock is a feature included in Find My. It turns on automatically when Find My is turned on, and the Apple Account password is then required before anyone can turn off Find My, erase the device or reactivate it.
