Hi att950-

Yes, both numbers must match for your warranty protection, if the case is new and still under the warranty period.

This is consistent with all Rimowa case sales and warranties.

I would contact the online seller, or store and bring this to their attention. If this was an Ebay purchase, then file a Resolution Claim with them immediately under " Received goods - Not as Described. "

Send it back and exchange it to a matched set ( Rimowa case ID Nr. and matching barcode warranty booklet Nr.), or ask for a full refund.
