Who checks and verifies whether I am registered?

The packaging register is centrally managed and monitored by the ZSVR. The ZSVR also works with other authorities (customs authorities, trade supervisory offices). In addition to this regulatory oversight, marketplaces such as Amazon and eBay are increasingly taking their own action and checking their sellers' LUCID registrations. You cannot simply hope that no one will ever catch you — there are multiple layers of enforcement. Regulatory checks are random, but with over 20,000 proceedings initiated per year, the chance of being checked is real. Marketplace enforcement is even proactive: if your registration lapses, the marketplace can suspend your account before any regulatory penalty is imposed.
