Hermès Stamp Letters Explained: How to Read the Year Code
By The Leather Expert · Glossary Entry
The stamp year code is a letter stamped inside a Hermès bag that indicates the year it was produced, following the house's internal alphabetical dating convention used across most modern production.
How the System Works
Hermès uses a rotating alphabetical system where each letter corresponds to a production year, generally located within a stamped symbol shape that itself changes periodically. Because the alphabet cycles and Hermès occasionally adjusts its own conventions, the letter alone doesn't always map to a single, unambiguous year without additional context.
A single stamped letter carries decades of quiet institutional record-keeping behind it.
Where to Find It
The year stamp is typically located inside the bag, often near the craftsman's blind stamp discussed elsewhere in this glossary. Exact placement has shifted somewhat across different production eras, so its precise location can itself be a helpful clue when dating a piece.
Why It Matters to Buyers
- Helps establish an approximate production year for vintage or pre-owned pieces
- Useful cross-reference alongside other construction and hardware details
- A correct-looking stamp alone doesn't confirm authenticity on its own
- Specialist references exist for buyers who want to date a piece with precision
Frequently Asked Questions
The stamp is typically found inside the bag, often near the craftsman's blind stamp, though exact placement has shifted somewhat across different eras of production.
Yes, because the alphabet is finite, letter codes eventually repeat, so the stamp alone isn't always sufficient to pinpoint an exact year without cross-referencing other construction details.
No, a correct-looking stamp alone doesn't confirm authenticity. Stamps should be assessed alongside overall construction, materials and other details as part of a complete authentication process.
Yes, Hermès has adjusted stamp conventions across different production eras, which is part of why dating vintage pieces accurately often requires specialist knowledge.
