Hi,

Thanks for asking, you can Log onto iCloud.com/find and search for your device. Alternately, try the Find My app on a different Apple device that you own. If your iPhone, iPad, or iPod touch isn't included in the list of devices, Find I was not activated. If Find My was not activated, you can still secure your account. you can get the link from apple's official support.

Hello ~ Take a look at the link that I posted…it’s a great article to recommend in this type of question as it gives the OP all the information that that they should need. Keep on helping:)
