Yes sometimes they have a code on the paper that has your data, but... as far as I know, this is not to track it, cause eventhough you use this number in a track service page, you'll get an error, so, after the shops says that they have sent the order... you cannot know anything until you get it in your house if your lucky, or in the post office, for example in Spain, now, a few months ago no, if the weight is more than 500grs, wich is really really easy, in your home only get a nottification, but nothing else, you have to go to the office to get your order
