Do all Dior bags have serial numbers?

No, Dior bags don't all have serial numbers. In fact, the brand uses date codes in place of them. The date code begins with a two-digit number that represents the manufacturing year. A two-letter code specifying which factory produced the bag comes next. At the end of the date code is a four-number sequence. The first and third numbers correspond to the month of production, and the second and fourth numbers tell you the calendar date. For example, a date code ending in 1212 means the date of production was November 22. On 1stDibs, find a variety of expertly vetted Dior bags.
