How to Authenticate Hermès Bag

Buying a Hermès bag, especially a Birkin, Kelly, or Constance, is a true investment in preloved luxury fashion. With high-quality counterfeits on the rise, knowing how to authenticate a Hermès bag is essential for anyone purchasing pre owned Hermès handbags. Below is a complete step-by-step guide trusted by collectors and consignment boutiques.

1. Craftsmanship and Materials

Hermès bags are handcrafted by artisans using the saddle stitch technique.
Stitching must be perfectly even, with no loose threads or fraying.
Only premium leathers are used: Togo, Epsom, Clemence, Box, Swift. They should feel rich and natural, never plastic-like.
Hardware (buckles, locks, clasps) should be solid and heavy. Authentic Hermès hardware is engraved with “Hermès” or “Hermès Paris”, in crisp, clean font.

2. Heat Stamp and Logo

Every authentic Hermès bag carries a heat stamp reading “Hermès Paris Made in France.”
Typically found under the front flap or inside the bag.
Font must be sharp, evenly spaced, and pressed directly into the leather—never printed or sloppy.

3. Date Stamp and Craftsman ID

Hermès uses a date code system to mark production year.
Found on the inside flap or leather tab, usually a letter in a shape (e.g., “D” in a square).
Each bag also has a craftsman’s ID code—a number or symbol identifying the artisan.
Always ensure the date stamp aligns with the year the seller claims.

4. Hardware Quality

Authentic Hermès hardware is plated in 18k gold or palladium.
It should feel weighty and luxurious.
Zippers, clasps, and locks should move smoothly and feel sturdy.
Locks and keys should carry matching numbers.

5. Hand-Stitching

Hermès is renowned for its saddle stitching.
Under magnification, each stitch should resemble a neat “X.”
Stitching is consistent, precise, and flawless throughout.

6. Interior Details

Interiors are lined with premium leather, often goatskin or calfskin.
Lining colour complements the exterior.
Look for clean seams, carefully constructed pockets, and no bubbling, glue marks, or uneven lines.
Interior may feature additional Hermès stamps mirroring the exterior.

7. Dust Bag and Packaging

Authentic Hermès dust bags are thick cotton flannel with a drawstring closure.
Usually beige with the brown Hermès logo in the centre.
Packaging includes:
Iconic orange Hermès box with crisp edges.
Branded ribbon and protective wrapping materials.
