Do I need active listings in all European countries?

If there has ever been an offer for your product on another marketplace, you need to have an active listing in this country. Otherwise it is not possible to use pan-European shipping (PAN EU). For example: If your products are listed in six marketplace countries but you only have active offers in five of these countries, PAN EU is not possible.
Caution: Amazon often creates listings for you in other European countries without you knowing. Be sure to double-check your ASINs on all marketplaces!
