How do I tell what year my Celine bag is?

To tell what year your Celine bag is, look inside for the date code. You may find it embossed directly on the lining or displayed on a tag sewn into the lining. The code will consist of three sets of numerals separated by hyphens. With most bags, the first and third digits refer to the week of production, and the second and fourth numbers tell you the year of production. For example, 1135 would appear on a bag made the 13th week of 2015. With some older bags, the date code is in sequential order, with the first two digits corresponding to the week and the final two representing the year. Find a range of Celine bags on 1stDibs.
