As one of the most sought-after luxury brands in the world, Hermès bags such as the iconic Birkin, Kelly, and Constance are often the targets of counterfeiters. For collectors, fashion enthusiasts, and those looking to buy a pre-owned piece, knowing how to authenticate an Hermès bag is crucial to ensuring you're investing in an authentic and valuable item. In this blog, we will provide you with expert tips on how to authenticate an Hermès bag like a pro, so you can spot the fakes from the real deal with confidence.

Know the Key Characteristics of an Authentic Hermès Bag
Before diving into the specific details of authentication, it's important to familiarize yourself with the key characteristics that define a genuine Hermès bag. These features are consistent across all authentic bags:
- High-Quality Craftsmanship: Hermès bags are handmade with the utmost attention to detail. They showcase the brand's craftsmanship, and any signs of poor stitching or uneven finishes should raise a red flag.
- Timeless and Classic Design: Authentic Hermès bags are known for their classic and timeless designs. Any bag that feels too trendy or out of place with the established Hermès aesthetic is likely a counterfeit.
- Luxury Materials: Genuine Hermès bags are made from the finest exotic leathers (such as Togo, Epsom, Clemence, Crocodile, Ostrich, etc.) and are finished with top-quality hardware. If the leather feels flimsy or the hardware looks cheap, it’s a sign the bag may be fake.
Examine the Stitching
One of the most obvious ways to authenticate an Hermès bag is by inspecting the stitching. Hermès bags are renowned for their precise, even, and flawless stitching. Here’s what you should look for:
- Even Stitching: Authentic Hermès bags feature perfectly uniform stitching with no stray threads or inconsistencies. The stitching should be tight, straight, and have the same color as the leather.
- Number of Stitches: For the majority of Hermès bags, there are 5 stitches per inch. The stitching should be tight but not so tight that it distorts the leather.
- Color of Thread: The stitching should be in a neutral or matching color to the leather, although in some rare cases, Hermès does use contrasting threads (such as for special edition bags). If the stitching stands out in a strange or unnatural color, it’s likely a fake.
Check the Hardware
Another way to authenticate an Hermès bag is by checking the hardware—the lock, clasp, key, and any other metal elements on the bag. Hermès hardware is made with precise craftsmanship and luxurious materials, such as gold, palladium, or rose gold. Here’s what to look for:
- Weight: Authentic Hermès hardware is typically heavier than counterfeit versions, which are made with cheaper materials.
- Engraving: On real Hermès hardware, you’ll find the brand’s signature engraving, usually saying “Hermès Paris” and sometimes a serial number or year code. The engraving should be clear, well-defined, and symmetrical.
- Finish: The finish on Hermès hardware is always smooth and flawless. If the hardware feels rough, bumpy, or uneven, it’s likely a fake.
Inspect the Leather Quality
Authentic Hermès bags are crafted from the highest-quality leather available. Each type of leather used by Hermès has unique characteristics, so it’s essential to understand what to look for with different leather types:
- Togo Leather: This is a textured leather with a soft, grainy feel. Authentic Togo leather will have a uniform, textured pattern with no visible imperfections.
- Clemence Leather: Clemence leather is a smooth, supple leather that has a subtle, natural sheen. It’s soft to the touch, and any wrinkles or lines should be natural, not forced.
- Crocodile and Alligator Leather: These leathers should have distinctive scales that are uniform and well-defined. The pattern should look natural and consistent.
- Ostrich Leather: Ostrich leather has a signature “pores” or “bumpy” texture. The bumps should feel soft and smooth rather than rough or inconsistent.
If the leather feels synthetic, overly stiff, or inconsistent, it's a clear indicator that the bag is fake.
Check the Bag's Shape and Structure
Hermès bags are meticulously crafted to have perfect proportions, symmetry, and structure. Counterfeit bags often have irregular shapes, uneven corners, or poor construction that makes them look sloppy. Here’s what to check for:
- Shape and Structure: The bag should stand firm and maintain its shape, whether empty or full. Hermès Birkins and Kelleys, for example, should have clean, sharp edges with a defined silhouette.
- Corners: The corners of the bag should be neatly finished, with no loose threads or visible imperfections.
- Floppy or Stiff Bags: If the bag appears too floppy, rigid, or lacks proper structure, it’s likely a counterfeit.
Inspect the Blind Stamp and Date Code
Every authentic Hermès bag has a blind stamp that indicates the year of production and sometimes the artisan who created it. This is one of the most crucial authentication steps. Here’s how to check:
- Blind Stamp Location: The blind stamp is typically located on the interior of the bag, often near the inner flap or interior pocket.
- Date Code: The stamp will include a letter and symbol, which represent the year of production. For example, "A" might indicate the year 2017, and so on. Pay close attention to the font and placement—a genuine Hermès stamp is always clear and uniform.
- Consistency: Compare the blind stamp with authentic examples you find online or in-store. If it appears fuzzy, poorly stamped, or inconsistent with the typical Hermès design, it’s likely a fake.
Review the Packaging and Documentation
Authentic Hermès bags typically come with luxurious packaging and documentation. Here’s what you should expect:
- Dust Bag: Genuine Hermès dust bags are made from soft, high-quality fabric, and they should fit the bag snugly.
- Box and Ribbon: Hermès bags usually come in a signature orange box with a brown ribbon tied around it. The box should be sturdy and have the brand name clearly printed.
- Receipt and Tags: Ensure that the receipt and any tags that come with the bag are from an authorized Hermès boutique. Fake bags often come with poorly printed receipts or generic tags.
Consult an Expert
If you’re still unsure about the authenticity of your Hermès bag, it’s always a good idea to consult a professional. Many luxury consignment stores and online platforms offer authentication services, where experts can help you determine if your bag is genuine or fake. Alternatively, you can reach out to an authorized Hermès store for a formal authentication.
Authenticating an Hermès bag requires a keen eye for detail and knowledge of the brand’s design and craftsmanship. By following these tips and inspecting the stitching, hardware, leather, and blind stamp, you’ll be able to confidently authenticate an Hermès bag like a pro. Remember, when in doubt, always seek help from an expert to ensure you’re investing in an authentic and valuable Hermès piece.
