In the US, there's a product/service called Phantom Footprints that many dealers offer as an add-on. They affix tamper-evident stickers (the sort that leave a 'tattoo' if removed)/laser engrave a unique identifier that ties the vehicles/parts back to the owner in a database maintained by Phantom Footprints. On some vehicles, getting it installed and registering can even get you a discount on car insurance.
