Understanding Hermès date stamps

Often called a blind stamp, the mark is a production reference impressed into the leather. Older series run alphabetically, while the modern sequence is intentionally non-alphabetical. Craftsman marks or additional symbols may appear nearby and should not be confused with the year letter.

Hermès stamp calculator FAQs

What does an Hermès date stamp tell you?

The date stamp or blind stamp can indicate an approximate production year. It does not identify the model or guarantee authenticity.

Why do some Hermès letters repeat?

Hermès reused letters in different eras. The surrounding shape—plain, circle or square—is essential for determining the correct year.

Where is the Hermès blind stamp?

Its location varies by model and production period. It may be inside the bag, beneath a strap, behind a plaque or near an interior seam.

Can a valid Hermès stamp prove a bag is authentic?

No. Counterfeit items can copy plausible stamps, so the result must not be treated as authentication.

Important: A date stamp, serial prefix or correctly formatted code does not prove authenticity. Results are reference estimates and should be considered alongside construction, materials, provenance and professional authentication.
