What should I do with an iPad I found?

An iPhone picked up at a surplus store (if that’s what you meant by Good Will) is very likely Activation Locked, and therefore useless.

If this is Activation Locked, it will never be useful to you. Recycle it.

The All Too Common SAD Reality of Buying a used iPad/iPhone - Apple Community

If the iPhone is not Activation Locked, it can be reset. But you’re here, asking this, so it’s likely locked. Recycle it.

If you picked it up elsewhere and didn’t buy it at a surplus store, why bring it home? Turn it into local police or local lost and found where it was located.

You just need to turn it in at:

• Lost and Found
• Front Desk of nearby building
• Police

Of course the owner is able to track the phone, so if you are carrying it around, then they are able to see your location. There is no way for you to stop that from happening and if you could, a thief would do it as well to prevent the phone from being found. In some cases the owner may have entered contact information when they marked it as lost that will appear on the phone when you turn it on.

There is no reason why you should be carrying the phone around with you. All that you should be doing is to taking it to locations described above, or something similar, so the owner can track the iPhone and be able to pick it up.

Apple do you have any advice or guidance?

Thanks!

This is a user-to-user forum. Apple largely is not here, except to moderate it.

The others are correct. If you found a device, and want to return it to its rightful owner, turn it into a lost & found department or front desk (where the owner would logically come looking for it), or to the police.

Apple isn’t here. Just follow the advice already given. If the owner is tracking the phone then it is the phone they are tracking, not you. So if you’re concerned just make sure the phone is with you for the least possible time by handing it in as advised.
