FAQS

The most common questions from merchants and shoppers answered

Merchants

Is STAMP free for merchants?

Yes, TaxFree transactions are completely free for merchants.

Who guarantees VAT in the event of unvalidated invoices?

Stamp guarantees the VAT amount by pre-authorizing the customer's card at the time of purchase. There's no risk for the merchant.

Does Stamp require technical integration?

No technical setup required; you can get started right away. If you'd like to integrate Stamp with your POS or ERP, you can do so later.

Should I leave my current Tax Free supplier?

No. Stamp doesn't require exclusivity. You can continue to offer your current services and add Stamp as an option, letting your customers choose.

What does my customer need to do at customs?

To complete a Tax Free purchase, your customer must obtain the customs validation required for the country where they made the purchase and for their travel itinerary.

Purchases in Italy: the goods must leave the EU by the end of the third month following the month of purchase. Remind your customer to present the Tax Free invoice and the ID document shown on the invoice to the relevant customs office, and to keep the goods unused and available for possible inspection.

Purchases in Spain: if your customer leaves the EU through Spain, they must present the electronic Tax Free document (DER) at a DIVA kiosk. If the kiosk directs them to customs, they must follow the instructions and keep the goods available for inspection. Your customer must also meet the deadline that applies to their departure from the EU.

If your customer leaves the EU from a country other than the one where they made the purchase: they must follow the procedure of the relevant customs office. For purchases made in Spain, give them or remind them to bring a printed copy of the DER to present at the customs office of exit. Once validated, the customer must email STAMP a photo of the customs validation. This applies to purchases made in both Italy and Spain.

If your customer has a connecting flight or goods in checked baggage: advise them to check with customs where to get the validation before checking in their luggage.

Important: the discount applied at checkout does not replace customs validation. Make sure your customer knows this at the time of purchase.

Why do customers have to provide their phone number and/or email address?

The traveler's phone number becomes their personal access key. It allows them to link their passport and card details once and reuse them for future purchases without having to register again.

Why do customers have to provide their card details?

The card is pre-authorized as a VAT guarantee. This temporary hold ensures that the savings are properly disbursed after validation. Depending on the card type, the amount may appear as temporarily held.

How does customs validation work?

Within 90 days of purchase, your customer must present the invoice upon exiting the EU with the goods still unused and available for inspection.

In Italy: present the invoice to the customs office.
In Spain: Go to the DIVA kiosk at the airport and validate your invoices they will tell u if you need to go to customs or not. 

From another EU country: Submit your paper invoice and send a photo of the stamped invoice to STAMP.

Why do customers have to provide their travel document details?

By law, only non-EU residents can purchase Tax Free. To verify this, you need an official document proving your non-EU residence, such as a passport or national identity card.

Shoppers

Do I need to download an app to use STAMP?

No, it’s not necessary.

You can register by yourself in store and get your personal STAMP ID by scanning the QR code and just share your ID at checkout. Merchants can register you too. Easy and fast!

Why do I have to share my contact details?

They become your STAMP ID. It links your passport and payment card info securely so you don’t have to re-enter them every time you shop in a store that offers Stamp.

What do I have to do at customs?

To complete your Tax Free purchase, you must obtain the customs validation required for the country where you shopped and your travel route.

Purchases in Italy: The goods must leave the EU by the end of the third month following the month of purchase. Present your Tax Free invoice and the identity document listed on it to the appropriate customs office. Keep the goods unused and available for inspection.

Purchases in Spain: If you leave the EU through Spain, present your electronic Tax Free document (DER) at a DIVA kiosk. If the kiosk directs you to customs, follow the instructions and keep the goods available for inspection. Make sure you meet the deadline applicable to your departure from the EU.

If you leave the EU through a country other than the one where you shopped: Follow the procedure at the appropriate customs office. For purchases made in Spain, bring a printed copy of your DER to present to customs at your exit point. Once you have obtained customs validation, email STAMP a photo of the validation. This applies to purchases made in both Italy and Spain.

If you have a connecting flight or goods in checked luggage: Check with customs where to obtain validation before checking in your luggage.

The discount applied at checkout does not replace customs validation.

Why do I need to provide my credit or debit card details?

The store places a temporary hold (pre-authorization) on your card for the VAT amount. This is just a security step, no actual charge, and it ensures your VAT savings are guaranteed after customs validation.

What about my passport or identity card? Why is it needed?

By law, only non-EU residents qualify for VAT-free shopping. Your passport and identity card confirms your residency status and lets you benefit from the VAT exemption.

Can I use STAMP at any store?

STAMP is offered in stores across Italy, including many popular boutiques and shops. 

Look for the STAMP sign and ask for it at checkout!

You can also browse all participating stores directly in the STAMP app, so you always know where you can shop and save.

Do I have to stop using other TaxFree services?

No. STAMP doesn’t require exclusivity. You can use any service you like but once you stop paying VAT upfront, it’s hard to go back to waiting for a refund.
