Louis Vuitton has been placing date codes in almost every newly manufactured bag, wallet and small leather piece since the early 1980s. Sometimes date codes are hidden and may be difficult to find, but in most cases they are visibly stamped on the lining or onto an attached tag.
Louis Vuitton has changed the date code configuration multiple times, but the date code will always contain letters and/or numbers. Below is a quick guide to deciphering the meaning of date codes.
Early 1980s and Before: No Date Codes.Louis Vuitton did not use date codes before 1982, therefore older vintage pieces can not be pinpointed as accurately as newer ones.1982 to Mid 1980s Date Codes: Three or Four Digits.Louis Vuitton changed the date code system in the mid-Eighties to include letters that indicate the factory where pieces were manufactured. Like in the early 1980s, the first two numbers indicate the year, and the last one or two numbers indicate the month.
In 2007, Louis Vuitton changed the four digit numbering system. Instead of indicating the month an item was manufactured, the first and third numbers now represent the week. The second and fourth numbers still represent the year. The letters continued to represent the specific factory where the item was manufactured.
