With a combined in-house knowledge of over 20 years on reselling and handling luxury designer goods, we have seen all types of bags! By using our in-depth knowledge and as well as using the latest AI technology, we can offer authentication service for luxury designer handbags and much more. We can even do belts and small leather goods such as watches, coin purses and men’s bags and luggage bags.

Unlike other authenticators, we do not believe in authenticating bags from pictures, part of our authenticating process is that we are required to see the bag in person. We believe that you also need to handle the product.

How long will it take?
As soon as the bag has arrived at our London office, the process only takes one day, we can ship your bag out the next day along with a copy of the Luxury Promise Certificate.*

What if the bag is deemed fake?
If your bag does not pass our authentication process, we will reduce our authentication fee by 50%, your bag will be returned, no certificate will be issued.*

£35 per item for all brands
£75 per bag for Hermes only
All authentication comes with a Luxury Promise certificate. Prices include UK delivery only.

Brands we can authenticate:
Balenciaga, Bottega Veneta, Burberry, Celine, Chanel, Chloe, Dior, Fendi, Goyard, Gucci, Hermes, Louis Vuitton, Prada and Saint Laurent.

Next step is to submit your inquiry by email: with your authentication service in your title and we will take care of the rest!

At Luxury Promise, you can buy, sell, restore and authenticate with Confidence!

*Please note the customer is responsible for sending in the bag. Free delivery is only available in the UK. If a bag is deemed to be real or fake we do not get involved with seller disputes outside of Luxury Promise Ltd.
