Understanding Hermès Date Codes and Serial Numbers

Check out our Hermès collection and Birkin bags!

Every authentic Hermès bag carries a secret language etched into its leather, a quirky dating system that quietly hints at when and where your treasured piece was made. Hermès date codes and serial numbers act as the bag's DNA, offering clues about its manufacturing year, the craftsman behind it, and its authenticity, details that can seriously affect value and peace of mind.

With so many convincing fakes swirling around the luxury market, collectors and enthusiasts really need to get a handle on these mysterious markings. Whether you're eyeing a vintage Kelly at auction or just want to double-check that Birkin you scored, decoding these stamps might save you from a costly mistake.

Let’s dig into the evolution of blind stamps, how to actually find these tiny markings on different bags, and what to look for when you’re authenticating. You’ll see how to crack Hermès’s cryptic code, spot red flags, and why these little stamps matter so much in the world of high-end handbags.

Key Takeaways

• Hermès date codes reveal the manufacturing year and craftsman info, key for authentication and value
• These blind stamps have shifted from circles to squares to bare letters since 1971
• Proper authentication means looking at more than just the date code; craftsmanship and materials matter too

What Are Hermès Date Codes and Serial Numbers?

Hermès puts two main marking systems on their bags: date codes (to show when your bag was made) and serial numbers (to ID the craftsman who made it). Together, they’re crucial tools for anyone buying or selling Hermès.

Purpose and Importance in Authentication

Date codes and serial numbers work as primary authentication markers for genuine Hermès bags. Every real Hermès bag has them, so they’re essential for checking legitimacy.

The date code tells you the year your bag was made. That matters, some years are more collectible than others, and collectors will pay extra for bags from certain eras.

Serial numbers point to the artisan who crafted your bag. It’s a personal touch and a nod to Hermès’ old-school approach to quality. Each craftsman adds a bit of accountability with their mark.

Authentication experts always check both markings when they’re evaluating a bag. Placement, font, and depth have to fit Hermès’ standards for that year. Counterfeiters often mess up these details.

Key Differences Between Date Codes and Serial Numbers

Feature	Date Code	Serial Number
Purpose	Year of manufacture	Specific craftsman
Format	Single letter (sometimes with shapes)	Alphanumeric combo
Location	Varies by style/year	Usually near date code

The Hermès date code is a single letter, sometimes surrounded by a circle or square. From 1945-1970, it was just a plain capital letter. Circles came in 1971-1996; squares took over in 1997.

Serial numbers mix letters and numbers, but they don’t follow the same system as date codes. They’re unique to each craftsman and batch.

Both are "blind stamps", pressed into the leather, no ink or color. It keeps things subtle while still providing authentication.

The Hermès Blind Stamp Decoded

The blind stamp system gives you the production year and the craftsman’s identity. Knowing how to find and read these marks helps you authenticate and trace your bag’s story.

Understanding the Blind Stamp System

We call it a "blind" stamp because Hermès presses it into the leather, no ink, just a tactile impression. This kicked off in 1945 and has gone through five eras since.

From 1945 to 1970, Hermès used simple letters. Then came the circle era (1971-1996), then square stamps (1997-2014).

Since 2015, the format changed again. Modern bags show an "L LL NNN LL" pattern: the first letter is the year, the rest identify the craftsman.

Each era uses the alphabet a bit differently. For example, the D square stamp marks the year 2000, which helps date bags from the square era.

Blind Stamp Information: What's Included

Your Hermès date stamp gives you two things: production year and craftsman ID. The year is a single letter; craftsman info changes by era.

Bags before 1945 don’t have stamps. From 1945-2014, you’ll see a letter (sometimes with a shape) and craftsman marks nearby.

Modern stamps (since 2015) combine everything into one code. First letter = year, others = artisan.

Some 2011 bags have weird double-blind stamps with overlapping letters. It’s a known quirk, not a sign of a fake.

Distinguishing Hermès Date Stamps from Other Stamps

The blind stamp stands apart from other bag markings. It’s always pressed into the leather, never printed or painted.

Look for it in different spots depending on the bag. Birkin and Kelly bags usually have it inside the interior pocket or along the seams.

Don’t mix up the date stamp with size, model, or hardware stamps. The Hermès date stamp sticks to the alphabetical code system.

A real stamp feels crisp and clean to the touch. The letters should be evenly pressed and lined up nicely inside their shapes (if there’s a shape).

Locating Hermès Date Codes on Your Bag

The hermès date stamp location jumps around depending on model and year, but we’ll help you hunt them down. Most date codes are blind stamps tucked away in the leather, hidden from plain view.

Popular Models and Where to Look

Birkin bags put their hermès date stamp inside the front flap, usually left side near the closure. It’s subtle, and you’ll need good light to spot it.

Kelly bags hide date codes in similar spots. Check inside the flap or along the interior sides where the leather meets hardware.

For Constance bags, look inside the main compartment, along the interior walls or near the closure.

Evelyne bags usually have date codes on the inside side panels. The perforated design doesn’t mess with stamp placement, so check the smooth leather inside.

Lindy bags keep their stamps inside the main compartment, often on the side walls where they’re safer from wear. The relaxed shape actually makes the stamp easier to find than on more structured bags.

Variations by Year and Bag Style

Date code placement has changed a lot over Hermès’ history. Pre-2000 bags sometimes have stamps in more obvious places, while newer ones tuck them deeper inside.

Vintage hermès bags from the 1970s or 80s might show stamps near the base or on prominent interior spots. These were easier to find but wore down faster.

Modern bags hide hermès date stamps to keep them safe from daily use. Smaller bags (like Mini Kelly or Birkin 25) squeeze stamps into tiny spaces, so you’ll have to look closely.

Special editions and exotic leathers play by their own rules. Crocodile and alligator bags usually have stamps where they won’t mess up the scales, and limited editions might add extra markings.

How to Read Hermès Date Codes

Hermès uses a letter and shape system for manufacturing years, with different formats from 1971 onward. The system went from circled letters (1971-1996) to squared letters (1997-2014) to bare letters (2014-present). 2014 is a transition year.

The Letter and Shape System Explained

Each date code starts with a letter for the year. Sometimes, extra letters show the craftsperson’s workshop.

From 1971 to 1996, the year letter sits in a circle. They go from A to Z, then start over.

Between 1997 and 2014, the year letter moves inside a square. Bags from this era are easy to spot.

After 2014, Hermès switched to bare letters, no shapes. It’s a cleaner look and still in use.

Workshop letters help ID the artisan. These extras add authentication value and link your bag to its maker.

Transition Years and Notable Exceptions

2014 is tricky because Hermès changed systems mid-year. You’ll find some bags with squared letters, others with bare letters.

Early 2014 bags usually have the square format; later ones go bare. Both are legit for that year.

Stamp placement and clarity sometimes get weird during these shifts. It’s more about manufacturing changes than fakes.

Some limited editions or special orders might have different stamps. If you’re unsure, a pro authenticator can help.

Date Code Charts and Year References

Here’s how the letters line up:

A = 1971, 1997, 2023
B = 1972, 1998, 2024
C = 1973, 1999, 2025

It keeps going alphabetically, with each letter standing for years about 26 years apart. Hermès skips I, O, and Q to avoid confusion.

To nail down the year, check the shape (circle, square, or bare) and other bag features like hardware and construction.

Keep this chart handy when shopping. The combo of letter, shape, and bag details gives you the full story for authentication.

Date Codes for Authenticity: Tips and Best Practices

Date codes are your first defense against fake Hermès bags, but you need to look closely and consider the context. The details matter, from stamp sharpness to the production timeline.

Spotting Fakes Through Stamp Details

We’ve seen plenty of fake Hermès bags with bad date stamps that give them away. Real stamps are crisp and deeply pressed into the leather, never fuzzy or shallow.

The letter should sit perfectly in its shape (circle or square). Counterfeiters rarely get this right.

Font consistency is huge. Hermès sticks to specific lettering, and it stays the same across all real bags from a given era.

Fake stamps often show uneven depth or look “burned” into the leather instead of cleanly pressed. The leather should have a slight indentation, not discoloration or rough edges.

Location is key. After 2016, Birkin and Kelly bags need stamps on the left interior side. Older ones should have them on the strap area.

Cross-Referencing Bag Details and Production Years

We always make sure the hermès date code matches the bag’s claimed specs. This catches a surprising number of fakes.

Double-check online resources to see if Hermès actually made your model, size, leather, and color that year. Some combos were only available for a short time.

Hardware styles change over time. Older bags have different clasps, zipper pulls, and metal finishes than newer ones.

Stitching and construction methods have evolved too. If a bag claims it’s from 2010 but looks like a 2020 build, something’s off.

Serial numbers should line up with date codes. The craftsman number is separate but helps confirm authenticity when both match up.

Avoiding Common Misinterpretations

People often misread date stamps because of bad lighting or not knowing the code system. Always use bright, direct light, a magnifying glass doesn’t hurt.

Transition years cause confusion. 2014 bags might have square or bare stamps, thanks to Hermès switching things up.

Don’t assume newer is better. Some collectors love vintage, and old date codes don’t mean a bag’s fake or low quality.

Special editions sometimes have unique stamps. Check your specific model before calling a stamp “wrong.”

Context is more important than the stamp alone. Pair date code checks with hardware, stitching, and provenance for real confidence.

Beyond the Code: What Else to Check on a Hermès Bag

While the date code tells you when a bag was made, you need to look at artisan marks and overall construction for a full authentication.

Artisan Initials and Additional Markings

You’ll often spot craftsman initials stamped near the Hermès date code. These show who made the bag.

Where to Look:

• Usually near the date stamp
• Sometimes on hardware
• Occasionally inside pockets or hidden spots

The artisan stamp is one or two letters. It’s tough for counterfeiters to copy them well.

Check for other authentic marks, too. Some bags have leather type stamps or special edition indicators. Made in France stamps should look clean, never smudged.

Hardware engravings are another giveaway. Real Hermès bags have crisp, evenly spaced letters on clasps and buckles. The depth and sharpness of these marks often separate real from fake.

Assessing Overall Craftsmanship and Quality

Beyond serial numbers or Hermès date codes, let's talk about the bag's actual construction. Real Hermès bags have stitching that's almost hypnotically straight, every saddle stitch lines up, and the tension feels just right.

Key Quality Indicators:

• Stitching: Hand-stitched, no weird gaps or loose threads
• Leather: Smooth grain, but you'll notice natural quirks or tiny imperfections
• Hardware: Feels heavy and solid, with flawless plating
• Edges: Hand-painted and sealed, no rough spots

The leather should feel both soft and structured at the same time. Look for those little grain patterns and subtle differences that only real hides show. Fakes usually go overboard with uniformity and end up looking plasticky.

Weight really makes a difference with hardware. When you pick up a genuine Hermès, the hardware feels hefty, counterfeits almost always skimp here and use lighter, hollow bits. The plating should look perfect, with no chips or weird discoloration if the bag's been cared for.

Frequently Asked Questions

Hermès date codes use single-letter stamps to show production years, and the format changes, sometimes a circle, sometimes a square, sometimes just a letter. Authenticating means checking if the stamp's in the right spot, matches the right year, and if the craftsman area code fits with the rest.

How can I tell the production year from the stamp on my Hermès bag?

Check the first letter in your Hermès stamp, it tells you the year. From 1971 to 1996, you'll see the letter inside a circle.

From 1997 to 2014, Hermès put the letter inside a square. After 2014, they dropped the shapes and just used bare letters.

Each letter lines up with a specific year, so you need to match the letter and its format to the right time period to figure out when your bag was made.

What do the different symbols and letters mean in Hermès serial codes?

Hermès skips the usual serial numbers and uses blind stamps with their own meanings.

That main letter? It shows the year. Extra letters or symbols tell you which craftsman or workshop area made the bag.

These codes help Hermès track where each piece comes from. When you put the codes together, you get a unique ID for every handmade item.

Is there a reliable method to verify the authenticity of Hermès serial numbers?

For real Hermès stamps, the format has to fit the production period. You want to see the right letter shapes, clear impressions, and the stamp in the right spot.

The stamp should make sense with the bag's leather, hardware, and construction style from that era. Fakes often mess up the letter format or use impossible year combos.

Pros check more than just the date stamp, they look at everything from stitching to hardware. The stamp helps, but it's not the only thing that matters.

Where can I find the date stamp on my Hermès accessory, and how can I decipher it?

You'll usually spot the date stamp on the inside leather surfaces. On Birkins and Kellys, it's inside the main compartment.

Wallets and smaller pieces hide stamps on inner pockets or card slots. They're embossed into the leather, not printed, so look for a subtle impression.

Some stamps are tricky to see, good lighting or even a magnifying glass helps. The impression should blend in with the leather, not feel out of place.

Can you explain the significance of the new 2025 stamp on Hermès items?

The 2025 Hermès date stamp sticks with the bare letter style they've used since 2014. This stamp lets us spot current production pieces in the wild.

New stamps matter for resale and for double-checking authenticity. A fresh stamp means the latest Hermès craftsmanship and standards.

Collectors love tracking these yearly stamp changes to follow production trends. The 2025 stamp? It's just the latest twist in Hermès' ongoing coding story.

Are there any tips for using an Hermès code checker app effectively?

Honestly, apps can help you figure out the year, but they're not enough to guarantee authenticity. If you're serious about verifying a Hermès piece, don't rely just on an app, it can't catch everything.

Use the app as a quick reference or a way to get started. But always double-check what you find. Compare the app's info with other sources or trusted guides. That extra step can make a big difference.

If you want real peace of mind, go to a professional authenticator. Apps are helpful once you know the basics about Hermès stamps and how they're supposed to look, but they're not the final word.
