How to Check iCloud Activation Lock Status
Quick answer: Go to Apple's official Check Coverage page, enter the iPhone's IMEI or serial number, and look for the Activation Lock line. If it says On, the phone is still tied to someone's Apple ID and cannot be fully used until it's removed.
Why Activation Lock Matters
Activation Lock is Apple's anti-theft feature. It ties an iPhone to the Apple ID that set it up, so even a full factory reset won't make the phone usable by anyone else. If you're buying a used iPhone, checking this status before you hand over cash is the single best way to avoid ending up with an expensive brick.
This is different from a carrier lock, which restricts which SIM cards work in the phone. A phone can be carrier-locked to AT&T or T-Mobile and have Activation Lock on at the same time—they're solved differently. If you're dealing with a carrier lock instead, see our guides for AT&T, Verizon, and T-Mobile devices.
3 Ways to Check Activation Lock Status
1. On the Phone Itself (Fastest)
If you have the iPhone in hand, this is the quickest method:
- Go to Settings > General > About
- Scroll down—if it shows a working Apple ID or asks to sign in, note that
- Try Settings > General > Reset > Erase All Content and Settings. If it asks for an Apple ID password to reactivate afterward, Activation Lock is on
2. Apple's Official Check Coverage Tool
Apple offers a free lookup at checkcoverage.apple.com. You'll need the IMEI or serial number, which you can find on the box, in Settings, or by dialing *#06# on the device. Enter it and look specifically for the Activation Lock field in the results.
3. Third-Party IMEI Checkers
Several paid services also report Activation Lock status, often bundled with blacklist and carrier checks. These cost a few dollars but can be useful if you also need to confirm the phone isn't reported lost or stolen before you attempt an unlock.
Tip: Always check Activation Lock before paying for a used iPhone, not after. Once you've paid, a seller who won't remove their Apple ID has little incentive to help you.
Activation Lock vs. Carrier Lock: A Quick Comparison
| Feature | Activation Lock | Carrier Lock |
|---|---|---|
| Set by | Apple ID / Find My | Wireless carrier |
| Fix requires | Original owner's Apple ID login or removal | Unlock request through carrier |
| Survives factory reset? | Yes | Yes |
| Where to check | Apple Check Coverage | Carrier-specific tools |
What If Activation Lock Is On?
You have three real options:
- Contact the previous owner and ask them to sign out of iCloud or remove the device remotely via Find My.
- Provide proof of purchase to Apple Support, who can sometimes remove the lock if you can show you're the rightful owner.
- Walk away from the deal. If a seller can't or won't remove Activation Lock, that's a serious red flag worth taking seriously.
Once Activation Lock is cleared, you may still need a separate carrier unlock depending on where the phone came from—check our guides for Cricket, Boost Mobile, or MetroPCS devices if that applies to you.
Common Mistakes to Avoid
Don't confuse a SIM lock screen with Activation Lock—they look similar but require completely different fixes. And never pay a stranger online who promises to "remove Activation Lock remotely" without proof; this is a common scam that legitimate services simply cannot deliver on, since only the original Apple ID owner or Apple itself can lift it.
Frequently asked questions
Is checking Activation Lock status free?
Yes. Apple's official Check Coverage tool is completely free and only requires the IMEI or serial number.
Can I remove Activation Lock myself without the original owner?
Generally no. You need either the original Apple ID credentials, Find My removal by the owner, or proof of purchase submitted to Apple Support.
Does Activation Lock affect carrier unlocking?
They're separate systems. A phone can be Activation Lock-free but still carrier-locked, or vice versa—check both before assuming a phone is fully usable.
Where do I find the IMEI to run a check?
Dial *#06# on the phone, check Settings > General > About, or look on the original box or SIM tray.
Will a factory reset remove Activation Lock?
No. Activation Lock survives a factory reset by design—that's exactly what makes it effective against theft.
