How do I read a Fendi serial number?
Start with where it is. On newer styles The Vintage Bar places it on the back of the interior brand tag or on a narrow leather tag. The Vintage Bar, Love That Bag etc and Madison Avenue Couture describe 15 to 17 characters, and The Vintage Bar says the groups are separated by dots or dashes. On two bags it dates to 2008, OPA Vintage shows the middle part of the number matching the start of the number marked ART on the shop card, and calls it the model number. EcoRing Indonesia says the first six characters are the style number. None of the guides read for this page says what the other groups mean.
