The fashion house of Hermès has been around for over 180 years. In those years they have designed many iconic items, most of them that come with a great history. When buying a vintage Hermès bag, you can easily find out how old it is using the date stamp.

What is the Hermès date stamp?

Hermès items don’t have a serial number or a date code, but there is still a way to find out how old your bag is. Hermès uses date stamps, often referred to as “blind stamps” or “craftsmen stamps”. When you understand how to read the date stamp, you will be able to tell which year the item was manufactured. The stamp can also be used to authenticate the bag, however, there are many counterfeit Hermès products that have a fake authentication code or stamp. Just because an item has a stamp, doesn’t mean that it is real! Hermès also does not issue authenticity cards with their bags, they have never done this before, and will probably never start.

Do all Hermès items have a date stamp?

All leather items made by Hermès after 1945 have a date stamp, that cannot be seen from the outside. The Hermès date stamp corresponds with the year of the manufacturing date of the item. This is different from a serial number, since all items made in one year get the same stamp.  In addition to this date stamp, you can find another stamp next to it that indicates the area at the atelier (workshop) where the bag craftsman works.

Hermès also uses a different kind of stamp to indicate different types of exotic leathers used in an item. This extra stamp can be found next to the branded “Hermès, Paris, Made in France”. However, a lot of vintage Hermès bags have no stamps at all, this doesn’t mean that they are not real.

Where to find the date stamp?

The date stamps used by Hermès are embossed with a hot iron and are always placed on the inside, or a place where it cannot be seen from the outside. The first places you should look for the Hermès date stamps are:

  • On either side of the strap
  • Inside of the bag
  • Under the tab (depending on the model)

In general, each type of bag has its own specific area where the code can be found. However, this can change depending on the year. For example, the date stamps on the Hermès Birkin and Hermès Kelly can often be found on the exterior arm or interior panel of the bag. While the Hermès Constance commonly has the stamp on the middle interior panel.
