In 2025 S.T. Dupont introduced its Digital Passport, secured by blockchain technology. Each passport is unique to a single piece and holds its own information — serial number, technical user manual and ownership history — and can be passed on to future owners.
A meticulously secured, tamper-proof certificate that protects your piece against counterfeiting and attests to its origin.
Activating extends the international warranty by six months — two and a half years in total. Without activation the warranty remains two years.
Gift or resell your piece together with its passport: the ownership history follows the object and protects its value on the secondary market.
Whether your piece was purchased online, in a boutique or from an authorized partner, it is eligible if it meets all four conditions below.
Please note: some ranges are currently excluded — notably limited editions / Haute Création and leather goods. Entering your serial number on the platform automatically tells you whether the piece is eligible.
Open your phone camera and scan the QR code on the “Digital Passport” card that came in the packaging. The activation page opens straight away.
Go to certification.st-dupont.com, or to the S.T. Dupont website under S.T. Dupont › Services › Digital Passport › Traceability, then choose “Request your digital passport”.
Three very simple steps, in less than a minute.
Using your phone camera, scan the QR code printed on the card supplied in the packaging. You can also open the activation link directly from a computer.
The certificate landing page appears. Tap the activation button to begin — this is what will guarantee the authenticity and ownership of your S.T. Dupont piece.
Enter the product serial number, then your ownership details. Attach a photo of your proof of purchase (invoice or receipt) and select the point of sale from the dropdown menu.
If your point of sale is not listed, tick “I can’t find my point of sale” and type the name in by hand. Fields marked with an asterisk are mandatory.
Once the information is complete, simply confirm. The request is then checked and processed as quickly as possible by the S.T. Dupont certification team, who will write to the address you provided.
You will receive an email from S.T. Dupont confirming the activation. Click “My personal space”, then log in to your S.T. Dupont account — or sign up if you do not have one yet.
Your piece now appears in “My Collection”. Open it to reach the details and associated services, then tap “Download my digital passport”.
Each passport is unique and tied to a single piece. It brings together the serial number, the product features, the activation and warranty-end dates, the place of purchase and the ownership history.
From your personal space, choose “Verify a digital passport”, enter the piece’s unique identifier and validate. This is the tool to use before buying a piece second-hand.
Your own personal QR code is displayed there too, so you can present your certificate at any time.
Whether you are gifting or reselling your piece, the passport follows it and protects its value.
Logged in to your account, open the relevant piece, expand the “Services” section and choose “Transfer my digital passport”.
Indicate whether this is a gift (“Offer my product”) or a resale (“Resell my product”).
You can add a personal message and photos of the piece. Then enter the new owner’s first name, last name and email address, review all the information and confirm.
An automatic message is generated for the recipient, which you can send by email or messaging app. They then activate the passport from the link they receive, creating their account and confirming the product information.
Available only from the customer’s personal account, on the web or mobile version.
Logged in to your account, open the piece, expand “Services” and select “Lock my digital passport”.
Select Loss, Theft or Other, add a comment if needed, then confirm with “Validate” — or “Cancel” to abort.
A confirmation screen appears: your digital passport, along with all associated services, is now locked.
