Model numbers can change as the items are changed over the years. T he greatest advantage of finding a serial number in your Gucci product is that you can use the number to check that the product is real. Important things to note about serial numbers: In the mid 2000's, Gucci eliminated the dot and the dash, using two lines of six digits or a top line of 6 and bottom line of 4 while wallets and small leather goods continued to have one line of digits separated by a dash. With the use of a consistent font, a few more changes were made to the format afterward.
From the mid 1990’s to the mid 2000’s, the pieces would typically have a top line of 3 digits followed with a dash/dot and then 4 digits and the serif font became more consistent with a few changes to the numbers. When Tom Ford became the Creative Director in 1994, the formatting of the serial numbers began to change and now serial numbers included two lines.
