The date code on a Hermes bag – historically a letter, sometimes enclosed in a shape – is one of the most useful details for dating a bag and understanding its history, and learning to read this alphabet system is a valuable skill for any collector. This code reveals the year a bag was made, aiding both appreciation and authentication. This guide explains the Hermes alphabet date code, how it has evolved, and how to use it to date a bag.
It is part of our terminology glossary hub and connects to our blind stamp guide.
What the date code is
The Hermes date code is a blind stamp indicating the year a bag was produced, historically rendered as a letter, sometimes enclosed within a shape such as a circle or square. Found among the bag’s markings, it allows collectors and authenticators to determine when a bag was made. This dating information is valuable for understanding a bag’s age, verifying consistency with its features, and appreciating its place in the house’s history.
Understanding the date code enriches both appreciation and authentication, letting you place a bag in time and confirm that its characteristics align with its supposed era. It is one of the key markings collectors learn to read, as our blind stamp guide explores.
The alphabet system
Historically, Hermes used an alphabet system in which each year corresponded to a letter, cycling through the alphabet over the years. This meant that a bag stamped with a particular letter was made in the year assigned to that letter, allowing collectors to date it by referencing the year-to-letter correspondence. The system provided a discreet, elegant way to encode the production year within the bag’s markings.
Because the alphabet cycles, the same letter recurs in different cycles, so context – the bag’s style, hardware and features – helps determine which cycle a letter belongs to. Reference resources that map letters to years are invaluable for accurate dating, as understanding the correspondence is key to reading the code, as our terminology guidance details.
Letters and shapes
The date code has been rendered in different ways over time, including a letter alone, a letter within a circle, and a letter within a square, with the shape indicating which cycle or era the letter belongs to. These shapes help distinguish between the recurring alphabet cycles, so a letter in a square corresponds to a different period than the same letter in a circle. Understanding the combination of letter and shape is essential to accurate dating.
This system of letters and enclosing shapes allowed Hermes to encode the year precisely across many decades, with the shape providing the context needed to place a letter in the correct cycle. Familiarity with which shapes correspond to which eras helps collectors read the code correctly, as our vintage guide touches on.
How the system evolved
The Hermes dating system has evolved over the years, with changes to how the date code is rendered and, more recently, significant updates to the approach. The traditional letter-in-a-shape system was used for many years, but Hermes has updated its methods over time, so the way a bag is dated depends on its era. Understanding this evolution is important, as the system for reading a bag’s date varies depending on when it was made.
Because the approach has changed, collectors need to understand which system applies to a given bag’s era to date it correctly. Staying informed about how the dating system has evolved ensures accurate interpretation, and reference resources that reflect these changes are valuable for dating bags across different periods.

Using it to date a bag
To date a Hermes bag using its date code, locate the code among the bag’s markings, identify the letter and any enclosing shape, and reference a reliable resource that maps the letter and shape to a year. Cross-check the resulting date against the bag’s style, hardware and features to confirm consistency. This process reveals the year of production, adding to your understanding of the bag and supporting authentication, as our blind stamp locator guide explores.
The date code and authentication
Beyond dating, the date code plays a role in authentication, as it should be correctly formed and consistent with the bag’s other features and apparent age. A date code inconsistent with the bag’s style, hardware or construction for the indicated year is a warning sign worth investigating. As with all markings, the date code should be assessed within a holistic authentication rather than relied upon alone, but a correct, consistent code supports genuineness, as our authentication guide stresses.
The recent change to the system
Importantly, Hermes has updated its date-stamping approach in recent years, moving away from the traditional letter-in-a-shape system to a new method. This means bags from the most recent era are dated differently than older ones, and collectors need to be aware of which system applies to a given bag. Staying informed about this change is essential for accurate dating, as applying the old letter system to a newer bag, or vice versa, would lead to incorrect conclusions, as our glossary hub reflects.
Reference resources that account for both the traditional and updated systems are the most reliable, ensuring you date a bag correctly regardless of its era.
Dating vintage bags
For vintage bags, the date code is especially valuable, confirming the era and helping verify that the bag’s features are consistent with its age. A vintage bag’s letter-and-shape code places it in time, aiding both appreciation of its history and authentication. Understanding the dating system relevant to a bag’s period is key, and the date code adds a fascinating dimension to owning a vintage piece with genuine provenance, as our vintage buying guide explores.
Why dating matters to collectors
Dating matters to collectors for several reasons: it establishes a bag’s age and place in the house’s history, supports authentication by confirming consistency, and adds to the story and provenance of a piece. Knowing when a bag was made enriches appreciation and can be relevant to value, particularly for vintage and collectible pieces. The date code thus connects a bag to its moment in time, a detail collectors genuinely treasure.
A tool, not the whole story
While the date code is a valuable tool, it is one element of understanding and authenticating a bag, not the whole story. It should be read alongside the bag’s style, hardware, leather and other markings, and used within a holistic assessment. The date code reveals the year, but the full picture of a bag comes from considering all its characteristics together, as our authentication guidance stresses.
Frequently asked questions
What is the Hermes date code?
It is a blind stamp indicating the year a bag was made, historically a letter often enclosed in a shape like a circle or square. It allows collectors to date a bag and appears among its markings.
How does the letter date system work?
Each year corresponded to a letter cycling through the alphabet, with an enclosing shape indicating the cycle or era. Referencing a letter-to-year map, with the shape for context, reveals the production year.
Why is there a shape around the letter?
The shape – such as a circle or square – indicates which alphabet cycle or era the letter belongs to, distinguishing recurring letters so the code can be dated accurately.
Has the Hermes dating system changed?
Yes. The system has evolved over the years, including updates to how the date is rendered, so the method for dating a bag depends on its era. Understanding which system applies is key to accurate dating.
