How do I track a stolen iPhone using my iCloud account?

Sorry, but no one on this user to user only forum, can track your phone. And Apple doesn't get involved in lost or stolen devices, so they won't be able to help you either.

Most thieves are pretty smart and put iPhones either in a Faraday bag or wrap them in aluminum foil, making them impossible to track. Most stolen devices are never recovered, no matter what options you may have.

This is all you can do if your iPhone is lost or stolen --> If your iPhone or iPad was stolen - Apple Support

On a final note. You may receive a message saying your phone has been found and it may appear to have come from Apple. It WON'T be from Apple. What the thief is hoping is you'll fall for their scam to get your logon credentials, so they can wipe the phone and sell it to someone, which makes them more money than just shipping it to some tear down facility where it will be taken apart for parts. DO NOT FALL FOR THE SCAM.

My iphone is stolen and its offline......

The phone is "Offline" for one of the following reasons:

The battery has run down

The phone was powered off

The phone is not near any other Apple devices that might pick up a Bluetooth signal from your phone

As iPhone thieves do, the thief has wrapped aluminum foil around your phone or placed it in a Faraday bag, so that the phone cannot send or receive a signal. Any iPhone thief knows this.

The phone has been quickly sold to a "fence" and it is on the way to a remanufacturing plant in China

I'm sorry, but the chances of ever locating a stolen phone, much less retrieving it are a tiny fraction above zero.

Be very careful if you receive a message from "Apple" or "Apple Support" notifying you that your phone has been found and you just need to provide a few more details.....(like your Apple Account and Password)......so the phone can be returned to you.

Apple does not get involved with lost or stolen phones, so any message like this that you might see is a scam that is trying to trick you into providing personal details so the bad guys can get into your phone.

The phone is gone. Contact your carrier to report the theft and ask them to "blacklist" the phone. Good idea to change the Password to your Apple Account as an extra precaution.
