Here is Apple’s advice for lost or stolen devices:
If your iPhone, iPad or iPod touch is lost or stolen – Apple Support
Use the Find My app to locate a lost or stolen device – Apple Support
Facilities to manage/recover a lost or stolen device are predicated on Find My iPad being enabled on the device before it was lost.
If the Find My iPad feature was enabled prior to it being “misplaced”, then if active, you would stand a good chance of locating it. However, if the feature was not activated prior to being misplaced - or the iPad has been inactive for more than 24 hours, the last known location will not be available - and the opportunity to use technical means to recover the iPad have been lost.
