Where is the blind stamp?
On a Birkin or Kelly, the blind stamp is typically found on the interior leather flap (under the main closure) or stamped into the leather beneath the handle. It usually appears as two separate characters: a date letter and a craftsman code (a letter identifying the individual artisan). Only the date letter corresponds to the year of production.
Frequently asked questions
- What is a Hermès blind stamp?
- A Hermès blind stamp is a small embossed letter stamped into the leather of a Hermès bag — usually on the interior flap. It indicates the year the piece was crafted. The stamp is accompanied by a craftsman code (a separate letter identifying the individual artisan).
- How do I read a Hermès date stamp?
- Find the single letter stamped inside your bag and note whether it has a border. Plain letters (no border) correspond to 1945–1970 or 2015–present. Letters inside a circle (○) are from 1971–1996. Letters inside a square (□) are from 1997–2014. Enter the letter and its border style into this decoder to get the exact year.
- Where is the blind stamp on a Hermès Birkin or Kelly?
- On a Birkin or Kelly, the blind stamp is typically embossed on the interior leather flap beneath the main closure, or stamped into the leather under one of the handles. It is usually a small letter — easy to miss unless you look closely.
- Does a correct date stamp prove a Hermès bag is authentic?
- No. High-quality counterfeit bags can replicate correct blind stamps. Authenticity must be verified by examining leather quality, stitching tension, hardware weight, and other physical details alongside the date stamp.
