You may have certain location restrictions for your campaign, like only allowing certain countries or requiring claiming the prize in-person.
We recommend specifically including the restrictions in your post caption, especially for more complex location restrictions.
If you have location restrictions, verify them with the winner
We do our best to automatically detect the winner's location and give you the information, but this isn't always accurate. So if you have location restrictions, we highly recommend verifying that a winner is qualified to claim the prize before approving the winner.
