You will still find the same two letters followed by four number format, however instead of using the staggered month and year, Louis Vuitton is now using a staggered Week of the Year and Year formula… so that… a date code that says SD 0077 is not a bag that was made in July of 2007, but is a bag that was made in the 7th week of the year 2007- so mid-to-late February of 2007. January 2007: Date Code changes to weekly format.Īgain, for whatever reason, Louis Vuitton made another change to the date code format beginning in January 2007. Using the number and letter combination- Louis Vuitton (and all of us!) can tell where and when that particular item came to be! Take the piece below for example (sorry, eBay limits my image size on Guide pictures…) These letters are an abreviation for the factory where that particular piece was manufactured. Later in the 80’s, Louis Vuitton started using a production code that consisted of the same three or four numbers as above… followed by two letters. Late 80’s: Three or Four Numbers Followed by Two Letters Obviously, if the month were October, November, or December… the last number would actually be two numbers… so a glasses case made in November of 1983 would have the date code 8311.īack “in those days” a date code was a date code… a number that could give you the general date when the item was manufactured. The first two numbers represent the year, and the last number represents the month. If you look carefully, you can see the number 831 near the bottom.
