Apple has removed its Activation Lock status checker on iCloud.com at some point in the past few days. The tool enabled users to enter the serial number or IMEI of an iPhone, iPad, or iPod touch and find out if the device is secured with Activation Lock, helping buyers avoid purchasing a device locked to another user.

An individual purchasing a used iPhone on eBay or another website, for example, was able to request the device's serial number and use Apple's tool to verify that Activation Lock had been turned off. If the device was still locked, or if the seller refused to provide the serial number, then it was likely lost or stolen.

The iCloud page where the tool was available now returns a "Not Found" page aka 404 error. Apple also removed the following reference to the tool from a related Find My iPhone support document earlier this week:
How do I check for Activation Lock before purchasing a used device?

When you buy an iPhone, iPad, iPod touch, or Apple Watch from someone other than Apple or an authorized Apple reseller, it is up to you to ensure that the device is erased and no longer linked to the previous owner's account.

You can check the current Activation Lock status of a device when you visit icloud.com/activationlock from any Mac or PC.
Apple has not explained why it removed the page. The company did not immediately respond to a request for comment.

Activation Lock, enabled automatically when you turn on Find My iPhone, is designed to prevent anyone else from using your iPhone, iPad, iPod touch, or Apple Watch if it is ever lost or stolen. A device with Activation Lock enabled requires the owner's Apple ID and password before it can be used, even if it is erased or reactivated.

Last year, a number of users who purchased a brand new iPhone experienced an Activation Lock issue where their device was locked to someone else's Apple ID. Apple disabled Activation Lock for affected users upon being provided proof of purchase, but it is unclear if the strange issue factored into the page's removal.

Activation Lock was introduced alongside iOS 7. The tool to check the Activation Lock status of a device had been available since October 2014.

I've wondered before if that tool allowed someone to abuse it to extract some information that they wouldn't otherwise be able to know.

For example, assuming they can get around the captcha, it could be a way to compile a list of all serial numbers and whether they are icloud locked, and thus compile a statistical analysis of what the odds are model by model of finding an icloud locked device.

Apple is closing doors for reselling/buying used iPhones (since this makes it nearly impossible for buyers provided with a serial or IMEI number to check wether an iPhone is locked or not before buying). If this isn't temporary, i don't see any other reason Apple is doing this except draining the market for used iPhones and selling new ones.

I wonder why, it was extremely useful. Maybe they are updating it?

I was worried about it too until I remember that when I bought a new iPhone 7 it was locked via activation lock (brand new, out of the box). When I took it back to the Apple Store the manager unlocked it for me. So perhaps Apple has simply decided proof of purchase is enough? (I hope not, as making "proof" of purchase is incredibly easy, but maybe ...)

It was probably because the bad guys were using it as well. They wouldn't just take it down for no reason. The con's outweigh the pro's on this occasion.

There's no "probably" about it. There's video showing Chinese operations set up to reset the serial numbers of stolen iOS devices in mass quantities, and Apple's Activation Lock checker is a vital part of the process.

And then you have a lot of news recently about brand new iPhones being locked to an Apple ID right out of the box because their legitimate serial numbers have been illegally assigned to a stolen device.

It's a tough problem to solve, but until Apple has a solution, they're not going to continue helping thieves.

It was useful to people buying used iPhones. When someone buys a used iPhone, Apple gets none of that money. Now you know why.
If I can sell my used iPhone at a higher price, I am more willing to pay a high price for a new iPhone. Already today, when I ponder whether to get a new iPhone or iPad, I do check used prices for my current device first to calculate the effective cost of a new iPhone or iPad.

Why the heck does Apple keep removing helpful features? I swear, every week there's something that Apple gets rid of. What is going on??

The question being asked is, "Why would Apple remove this tool?" and the answer is, "Because it is being used by thieves."

It's not that hard to solve. Just sign each serial number with a cryptographic key, and have the bootrom check the signature. If the signature is not valid, the device cannot boot.

Sure, current devices are SOL but moving forward this problem can be solved.

I watched one of the videos, it's pretty crazy. The thief actually desolders the flash memory from the iPad, puts it in a programmer, resets the serial number to one that's unlocked, and re-solders it back into the iPad. Absolutely nuts how much effort people will go through to bypass activation lock.

thats not what I asked

Very well... if you watch the video, you will see that these thieves use software to generate a bunch of new "potential" replacement serial numbers. However, there is no way to know if the serial number is currently locked or not. Only Apple's Activation Lock tool (now removed) can tell them that.

Without the tool, they can go ahead and take a guess, and pick a serial for reassignment. But they won't know if that serial is locked or not until they solder the flash chip back into the device, power it up, and attempt activation.

If you're dedicated, you can keep trying until you get lucky, or destroy the device in the process of desoldering/resoldering the flash chip. But as far as mass theft goes, it becomes a lot less feasible, as the process just potentially got a lot more time-consuming.
