For luxury collectors, investors, and Hermès lovers, understanding how to read Hermès date stamps is essential. Whether you're purchasing your first Birkin or expanding an established collection, knowing how to identify the year of manufacture can help authenticate your bag, estimate its value, and appreciate its craftsmanship on a deeper level.

Since 1945, Hermès has used a unique system of symbols, letters, shapes, and—more recently—alphanumeric codes to mark the production year and the artisans who created each piece. These discreet markings are known as blind stamps.

In this comprehensive guide, you'll learn:

• What Hermès blind stamps are
• Why they are important
• How the date stamp system has evolved
• Where to find stamps on different bag models
• How to accurately read date codes from 1922 to 2025+

Let’s begin.

1. What Is an Hermès Blind Stamp?

A blind stamp is a subtle heat-pressed marking placed directly onto the leather of an Hermès item.
Unlike other luxury houses, Hermès does not use authenticity cards, NFC chips, or overt branding. Instead, the brand embeds essential information inside the product itself.

A blind stamp typically reveals:

• The production year
• The artisan’s identifier (craftsman code)
• Special-order or material symbols

It is called a blind stamp because it is hidden, minimal, and often blends into the leather—making it invisible to casual observers and difficult for counterfeiters to replicate.

2. Why Is the Hermès Blind Stamp Important?

2.1 Authentication

Blind stamps are a critical tool used by:

• Hermès artisans
• Resale experts
• Collectors
• Luxury authenticators

Matching the blind stamp to known Hermès production timelines helps confirm whether a bag’s claimed year is accurate. A mismatched or absent stamp is a red flag for counterfeit goods, since Hermès never issues authenticity cards.

2.2 Repair Eligibility

Hermès operates under one of the strictest repair policies in the luxury world:
Only the original workshop that made the bag is allowed to repair it.

The blind stamp helps Hermès identify:

• Where the bag was made
• Which craftsmen completed it
• When it left the workshop

This ensures repairs maintain brand standards and craftsmanship lineage.

2.3 Valuation and Investment

In the resale market, value depends heavily on:

• Edition (classic, limited, special order, rare leathers)
• Condition
• Color
• Hardware
• Year of production

Certain years are highly desirable because they produced iconic colors or exceptional craftsmanship.
Collectors often seek specific years—similar to wine vintages—making the date stamp crucial for valuation.

2.4 Historical Significance

To Hermès connoisseurs, date stamps serve as a historical timeline. Each bag carries:

• The story of its creation
• The artisans behind it
• The era it belongs to

Understanding the stamp deepens appreciation for the bag as an art piece, not simply a fashion item.

3. Additional Stamps You May See on Hermès Bags

A Hermès bag may have 1–5 different symbols beyond the date stamp. These include:

• ^ (Caret) – indicates special characteristics or collections
• Horseshoe Stamp (∩) – Special Order (SO), fully customized
• Shooting Star – created for Hermès employees only
• S Stamp – sold at discounted Hermès sales (may have tiny imperfections)
• Dotted symbols – special-order indicators
• Double Dash – Varanus Salvator (lizard skin)

Hermès Exotic Leather & Custom Symbols

Starting in 2025, Hermès introduced a new standardized format:
Three letters + two digits
(plus a second line with two letters for additional artisan coding)

4. Do All Hermès Bags Have Blind Stamps?

Not always.
A blind stamp is present on:

✔️ Leather bags
✔️ Leather SLGs
✔️ Leather accessories

But not on:

❌ Fabric handbags (they use textile tags instead)
❌ Items made before 1944
❌ Bags where the stamp has faded naturally due to age

5. Where to Find the Hermès Blind Stamp

Hermès changes stamp locations frequently to prevent counterfeiting.
Typical locations include:

• Behind hardware plaques
• Reverse side of the closure strap (sangle)
• Inside the bag along the inner side panel
• Inside an exterior pocket
• On the interior upper-left wall (newer Birkins & Kellys)
• Birkin-Specific

Before 2015: On one of the sangles

After 2015: On the interior left side, at the top panel

 

6. The Complete Hermès Date Stamp Timeline (1922–Present)

Stage 1: No Stamps (1922–1944)

No date stamps were used.
Bags from this era rely on other authentication indicators such as stitching, hardware, and construction.

Stage 2: Single Letter System (1945–1970)

Hermès introduced simple letters, one per year.
No shapes, no additional symbols.

This is the earliest form of modern blind stamps.

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

A major change:

Letter + Circle = Production Year

This system ran for 26 years.
Toward the end of the era, Hermès began adding artisan marks next to the encircled date stamp.

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

The circular shape changed to a square.

This era includes the rise of iconic Birkins and Kellys in exotic leathers and rare colors.

Stage 5: Modern Streamlined Stamp System (2015–Present)

Starting in 2015, Hermès moved to a shape-free alphanumeric format.
The new system looks like:

A AA 123 AA

• First letter = Year (date code)
• Remaining characters = Artisan codes

Important characteristics of modern stamps:

• No circles or squares
• Letters are not alphabetical
• Hermès intentionally skips letters to fight counterfeiting
• Each bag has a unique craftsman identifier
• Placement varies depending on model

For example:
If the date letter is T, the next bag may use D, W, or Z—no predictable sequence.

This unpredictability makes fake production extremely difficult.

7. How to Decode Your Hermès Bag (Quick Guide)

When examining a blind stamp:

Step 1: Identify the main letter

This is the date code.

Step 2: Determine whether the letter is alone, circled, or squared

• No shape = 1945–1970 OR 2015–Present
• Circle = 1971–1996
• Square = 1997–2014

Step 3: Read the second part (letters & numbers)

This is the artisan code indicating the workshop and craftspeople.

Step 4: Check for any additional symbols

Horseshoe, star, dots → special categories.

Step 5: Match the code with the Hermès timeline

This confirms production year and authenticity.
