Authentication Services


Thank you for your interest in our authentication services. We are proud to provide expert authentications for designer handbags, trunks, and accessories. Whether you are interested in finding out the authenticity of a Louis Vuitton handbag you already own, need to authenticate a Louis Vuitton item you are interested in purchasing online, or want a certificate of authenticity for a piece you are about to sell – our services allow us to assist you with all our pre-owned Louis Vuitton authentication needs.

Online Authentication Services

After reviewing thousands of items through our authentication services we have ended our individual item authentication services.

It’s been a pleasure to review your items and determine their authenticity for the past 10 years.

Instead of an individual authentication we highly recommend purchasing our Authentication Workbook. This 20+ page instant download book covers everything you need to authenticate an item on your own. The best part is, it can be used again and again to help you authenticate an endless amount of items.

Authentication Workbook

Instantly downloadable Louis Vuitton Authentication Workbook that allows you to self-evaluate your Louis Vuitton bag authenticity. Covering everything from materials, date codes, tell-tale signs of fakes and more. Follow this step-by-step guide to determine the authenticity of Louis Vuitton bags over and over for years to come.

Hear What Customers Have to Say . . .

  • Thank you for being so helpful and working with me while I was thinking of purchasing the coveted Louis Vuitton Pochette Metis on eBay. I was able to make the purchase with confidence after you authenticated the handbag. Your attention to every detail was very much appreciated and being that the handbag was an auction item you worked really hard to authenticate it before time was up. I was really nervous about being scammed on eBay, but you and your team did an awesome job! Next time I purchase a luxury item on any pre-owned site I will definitely have you all authenticate it for me! – Kelly O.
  • When I was first looking to purchase a pre-loved Louis, I came across Legos in my Louis’s awesome info on how to spot a fake. When it came time to make a purchase, I wanted to make sure the bag I was buying was authentic and had it authenticated by Legos in my Louis. They were accurate, so prompt and had great customer service. I would use them again if I am to need it. – Samantha S.
  • Forget the hours of researching date codes and trademark stamps trying to navigate as a novice in the world of pre-owned designer handbags.  Handing it over to Betsy to analyze for a nominal fee was extremely easy, with an incredibly quick turnaround. Her extensive knowledge and passion in the field is obvious. Her friendly, yet professional persona was a pleasure to deal with to authenticate my bag. Now I have my go-to person for confidence in future purchase decisions. Lori C.
  • Betsy was great in the whole authentication process. Communication was amazing throughout making sure all pictures were clear and visible and the process was very simple. Thank you Legos in my Louis for making it simple to get my bag authenticated. Happy customer will return for sure! – Missy W.
  • Your authenticity report saved me lots of money. I recently sold my LV on eBay and the lady said it was fake. When eBay didn’t buy her story, she challenged the sale on PayPal. Because of you, not only did I win my eBay case, I won my PayPal case as well. Thank you for your expertise. You were so helpful and stayed in constant communication with me through the process. I would recommend your services to anyone! – Michelle M.
  • I am very happy with the speed, detail, and cost of your service. I wouldn’t hesitate to work with you again.  – Joi C.
  • You provided outstanding customer communication with the fastest of results.  I appreciated your ability to almost read my mind as to what I would need and the report that was provided was in my email before I knew it.  I sold the bag almost immediately and having my report from you gave me a high level of credibility with the customer.  Thank you….a super job …and I would most certainly recommend your services as well as use your services going forward. – Anonymous Denim Sac Plat

  • It was so easy to authenticate my bag.  I was able to easily and quickly upload pictures of my bag, and you requested more photos for those that were not clear enough.  The turnaround was quick, too. – Catherine N.
  • I finally found the perfect Loui but was hesitant to purchase since it was not coming from the store!  I contacted Legos in my Louis to authenticate it. Betsy was very knowledgeable and helpful. She knew what to look for and what were red flags.  I felt very confident making my purchase and now when I take my bag out on the town the stores even acknowledge its authenticity and give compliments! Because of Legos in My Louis I have a beautiful authentic 1987 Louis Vuitton Sac Plat Tote that was made in Paris in perfect condition! I highly recommend Betsy and will be having her authenticate my future purchases! – Heidi B.

  • This is my third time authenticating with you and I feel most comfort working with you. The second time the seller did not respond to messages on sending the dye codes and stamp so we couldn’t complete the process. I believe the response time played a factor, because I was asking for items hours (or days, I can’t totally remember) after I started chatting with her, she probably assumed I was not a serious buyer. -Iljeoma O
