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

For most people, ordering an online authentication is the fastest and most cost-effective way to accurately determine the authenticity of your design item. Turn around time for online authentications is usually 2 business days. We start counting business days as soon as we receive all the photos we need to start the authentication so be sure to include all the requested photos.

If you plan to resell your pre-owned bag in the future we highly recommend a Certificate of Authenticity (COA). We’ll provide you a PDF version of your Certificate of Authenticity which can be used when selling your designer bag in the future. This is a very valuable tool in ensuring that you get the maximum possible value for your used designer bag.

If you are considering purchasing a consignment bag from an online auction and need a quick authentication we do offer expedited services with a turn around of 24 hours or less. This means that we can authenticate a bag you are considering purchasing to help you avoid buying a knockoff bag online.

Order An Online Authentication

The pricing for our online authentications is listed below.

To start your order, click on the authentication service that matches your needs and begin the checkout process. You’ll be asked to fill out a form with several questions that will help us authenticate your design item. Please note that quality photos of the bag and specific areas are required to complete your authentication.

Order Instructions:

  1. Select the type of authentication you want and click “Order Now”
  2. Submit authentication payment through our secure Stripe payment portal.
  3. After payment processes, you will be directed to a page with final steps to get us your bag images or the listing link for the bag you want to pre-purchase authenticate.
  4. Once we have your completed authentication questionnaire and all the images requested, we’ll start your authentication.
  5. After we’ve completed your authentication we will provide the completed authentication, item identification or Certificate of Authenticity to you via email to the address provided on the order screen.

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 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
