Hermès Date and Authentication

Since 1945, Hermès has employed a unique system of blind stamps—small, embossed symbols on leather—to indicate the year of manufacture and other details. Unlike other luxury brands, Hermès does not include authenticity cards or leather tags; instead, the brand relies on these discreet markings to convey essential information. This guide will help you decipher Hermès date stamps, understand their importance, and locate them on your bag.

What Is an Hermès Blind Stamp?

An Hermès blind stamp is a heat-embossed marking on the leather, typically a single letter or a combination of letters and numbers, that reveals the year of production. Because it is stamped without color, it is called a "blind" stamp. These stamps are deliberately placed in inconspicuous locations, making them difficult to find and even harder to replicate. The blind stamp serves as a crucial authentication tool, as counterfeiters often struggle to replicate the precise embossing and correct coding system.

Why Is the Blind Stamp Important?

The blind stamp is vital for several reasons. First, it helps verify authenticity: if a bag lacks a stamp or the stamp does not match the expected format for its claimed year, it may be counterfeit. Second, the stamp aids in determining the bag's market value. Hermès bags are often considered investments, and their value can vary significantly based on age, rarity, and craftsmanship. Collectors may seek bags from specific years associated with unique designs or high-quality production. Thus, the blind stamp is not just a date marker but a historical record that adds to the bag's story and worth.

Types of Hermès Blind Stamps

Hermès uses various symbols alongside the date letter to convey additional information. Here are some common ones:

Caret (^): Indicates a specific collection or attributes.
Dotted symbols: Denote special orders.
Horseshoe: Signifies a custom-made item.
Double dash: Used for Varanus Salvator lizard skin.
Shooting star: Marks a piece made specially for Hermès employees.
'S' stamp: Designates a sale product, which may have imperfections.

For bags released after 2025, the format changes to three letters followed by two digits, with another two letters on a second line.

Where to Find the Blind Stamp

The location of the blind stamp varies by model and year, but it is always on leather items. Common spots include:

Behind a plaque
Inside the bag, on the top of the side panel
On the reverse side of the closure straps
Inside the exterior pocket

For the Hermès Birkin, pre-2015 bags typically have the stamp on one of the sangles (the narrow leather pieces connected by the front lock). On newer Birkins, look inside the bag at the top left side. Note that stamps can fade over time, so absence does not always indicate a fake.

The Evolution of Hermès Date Stamps

Hermès date stamps have evolved through five distinct eras:

Stage 1: No Stamps (1922–1944)

Before 1945, Hermès bags did not feature any stamps. The leather goods department was established in 1922, but it wasn't until after World War II that the brand introduced a coding system.

Stage 2: Single Letter (1945–1970)

Starting in 1945, Hermès began embossing a single letter to indicate the year. The system cycled through the alphabet, ending with the letter Z in 1970. These early stamps are simple, with no additional symbols.

Stage 3: Letter in a Circle (1971–1996)

From 1971, the date letter was enclosed in a circle. This era saw the introduction of additional symbols alongside the letter, but the encircled letter remained the primary indicator. Bags from this period can be identified by the circle around the letter.

Stage 4: Letter in a Square (1997–2014)

In 1997, the circle was replaced by a square. The letter inside the square continued to denote the year, with the last square stamp being 'R' in 2014. Other symbols might also appear near the stamp.

Stage 5: Streamlined System (2015–Present)

Since 2015, Hermès has used a more complex format: a date letter followed by a craftsman stamp consisting of letters and numbers (e.g., "L LL 123 LL"). The date letter is no longer enclosed in a shape. To thwart counterfeiters, Hermès deliberately mixed letters from the beginning and end of the alphabet, skipping some letters (like S in 2015 and B in 2018). This unpredictability makes it harder for fakes to replicate.
