Hermès Date Stamp Guide: Identify Your Bag’s Year with LegitApp Code Checker

Understanding the Hermès date stamp, also known as the Hermès blind stamp, is one of the most reliable ways to identify the production year of an iconic Hermès Birkin, Kelly, or Constance bag. Unlike many luxury brands that rely on printed serial numbers, Hermès uses a unique blind stamp system — letters and symbols debossed directly into the leather — reflecting the brand’s heritage of craftsmanship and discretion.

To quickly identify your bag's production year, use the LegitApp Hermès Date Code Checker, a free reference tool designed for buyers, collectors, and resellers.

What is Hermès Blind Stamp?

Hermès blind stamp consists of two parts:

1. The Date Stamp: A single letter (sometimes inside a circle or square) that identifies the year of manufacture.

2. The Craftsman Stamp: A unique sequence of letters and numbers identifying the specific artisan or atelier where the bag was handmade.

Hermès Date Stamp Eras Explained

Hermès has used four different date stamp formats over time.

1. Vintage Era (1945 - 1970): Single Letter (No Shape)

2. Circle Era (1971 - 1996): Letter inside a Circle

3. Square Era (1997 - 2014): Letter inside a Square

4. Modern Era (2015 - NOW): Random Single Letter

Each era follows a different logic, which is why using a reliable Hermès date code checker is strongly recommended.

How to Read a Hermès Date Stamp

Golden rule: Always check for a shape first. If there’s neither, use the first character.

For example:

1. If the stamp has a circled letter, that’s the year (e.g., circled Z → 1996).

2. If the stamp has a boxed letter, that’s the year (e.g., boxed J → 2006).

3. No circles or boxes? The first character gives the year (e.g., standalone B → 2023).

How to Use the LegitApp Hermès Date Stamp Checker

2. Identify the letter or symbol and whether it appears with a circle, square, or no shape.

3. Use the LegitApp Hermès Date Code Checker to find the corresponding production year.
