What is a LPN Number on Amazon?

Amazon LPN (License Plate Numbers) are used for Fulfilled by Amazon (FBA) item tracking (mostly with returns) and other internal processing uses, not directly specified by Amazon. LPN stickers will be placed over existing FNSKU stickers or barcodes. 

Amazon’s Definition is:

“A unique serial number that identifies specific items throughout the fulfillment process.”


These stickers are most relevant to a seller when they have products returned from the FBA warehouse in a removal order. 

Why does Amazon use a LPN Sticker?

  • These stickers are used for internal processing and tracking.
  • These numbers are correlated with the Amazon FBA returns report – in order to help track FBA customer returns internally.  

What does the Amazon LPN Sticker Look Like?

  • The LPN sticker will have the same format as the image below:

 How can the LPN Number Help the Seller Identify Amazon Returns?

The LPN number is a great starting place when a seller receives a removal order on the Amazon marketplace. These numbers can be manually scanned into an excel sheet and then be compared against the Amazon FBA report. Using this method will help the seller know why the item was returned to Amazon and for which orders. To identify LPN’s on the FBA returns report please use the steps below:

  1. Go to the Amazon Seller Central Home Page. 
  2. Move your Cursor to Reports and then Return Reports

 3. Click View FBA Reports.

 4. Click the Download Tab.                                                                   

 5. Chose an Event Date and Click Request .csv download.

 6. Once your file is ready, download the excel file and from here you can locate the order numbers returned, the return reason and the LPN number. This report can be compared with your manual returns sheet mentioned previously in this article.

I was fortunate to be part of MAG's first batch of its Advertising Internship Program. The timing was perfect for me as I was looking for an opportunity to learn more about Amazon PPC and at the same time to have hands-on training to work on accounts.Β Β 


When I started my internship, I listed down the things I wanted to learn. And I am happy to say that I've ticked all the boxes! My most favorite was "Optimization Using Bulk Files”. Bulk files and I, we did not get along at first, it was so scary seeing all those data! But I had a great mentor who guided me along the way. He patiently taught me step by step on how to process the data. He was very enthusiastic in answering all of my questions. He supported me until I gained the confidence in uploading my first, second, third (and so on) bulk uploads.Β 


The biggest advantage in working with MAG (and I must say one thing that I always look forward to every week) is its Weekly Ads Training. Every week, we discuss various topics about PPC. Interns/Ads Specialists/Ads Managers, we all share knowledge, information, and updates about PPC. During our discussions, we exchange ideas and feedback. It became an avenue not just to learn a skill, but also to clear any vague or ambiguous PPC topics.Β 


For me, the biggest disadvantage is the work schedule. As an Intern, I have to follow EST timing. The time difference from my location was only 8 hours, but being a morning person, I really struggled to keep myself awake. But if you are a night owl, then this will not be a problem for you.


So if you are considering joining the MAG Advertising Internship Program, my advice to you is to take action - APPLY NOW! The knowledge that you will gain and the skill that you will develop from this program will be invaluable. And who knows? From being an Intern, you might be the next one to be promoted as Jr. Ads Specialist!Β
