Owing to European and especially BaFin AML regulations LBB/AB will have to KYC you very correctly. This will be much more exact that UK or USA processes. It would be a bad idea to supply any address at which you are not actually resident.
Furthermore AB will increase its prices in December so as to compensate for its reduced interchange incomefrom your use of the card inside Europe. This is a result of EU regulation which hits in December and limits the "bank pricingc cartel" as well as requiring full price transparency to the merchant.
