I have a quick question regarding my new Diorama bag and the tag inside. I am used to the Chanel ones that have a series of numbers that match the authenticity card, but is Dior different? I notice inside my bag it appears to have a sequence of 2 x numbers, 2 x letters, 4 x numbers ( I think thats what it is as it is hard to read). But my authenticy card is a series of 11 numbers and different. is this normal? I just want to be sure that it is and not a mix up at the boutique. I am only new to Dior so forgive my question if sounds dumb.
