What is MPN on eBay? – This is a common question new sellers on eBay often ask when trying to list their products. Also, some buyers who have heard of it want to know more about this important concept in selling or buying a product on eBay
. Whatever reason you want to know about MPN on eBay, I am here to help you. This guide will cover in detail what MPN on eBay is all about, how you as a seller can add it to all your listings on eBay, how a buyer can use it to quickly identify the product they want to purchase, the benefits of MPN, and other questions related to it.
What is MPN on eBay?
MPN which stands for Manufacturer Partner Number is a product identifier that helps buyers easily find products they are looking for on eBay. According to Oberlo, there are over 1.7 billion listings on eBay.
So it is hard for a buyer to easily spot the product they want to buy without using MPN.
eBay wants to improve user experience on its platform which was why it announced in March 2015 that sellers of branded items in certain categories must include Manufacturer Partner Number ( MPN) and Globe Trade Item Number ( GTIN) to complete new listings on eBay.
This policy affected previously listed items as sellers had to add MPN and GTIN to their items and relist them manually.
How does MPN work on eBay?
A manufacturer or seller on eBay is required to add a unique code to any product they want to list on eBay. This code which serves as an identifier can be added to the packaging or the product itself. A buyer looking for a particular product from a manufacturer will use the MPN code which is unique to such a product to look for it on the eBay search bar.

For example, a buyer searching for a product on eBay with MKJ73LL/A MPN code will enter it on the eBay search bar and click on Search.
Products with the same MPN code will be displayed in the search results as seen in the screenshot below.

That’s why it is important for a seller to accurately state the MPN of a product they list on eBay; otherwise, shoppers won’t find them on search results. If you are a seller on eBay that sources products in bulk from Aliexpress, it may be hard to manually list and add MPN to all of them on eBay. You can use Aliexpress eBay lister tool which eBay allows to ensure that you list and add MPNs accurately to all categories of products that are affected.
Benefits of MPN on eBay
It is not news that eBay made adding Manufacturer Partner Number (MPN) to certain categories of products compulsory. Although this policy is aimed at improving user experience, eBay sellers tend to benefit from it. That’s why it is advisable you add MPN on any product you list on eBay irrespective of category. Let’s look at the benefits of MPN on eBay.
1. Help buyers find what they are looking for easily
A shopper who sees a product they think will be valuable to them is likely to check the MPN number or any other form of product identifier it has.
If such a shopper shop on eBay, entering the MPN on the search bar on eBay will make it easy for them to identify the product and make a purchase easily. So instead of typing the name of the product and spending much to reading product details to be sure, an MPN code will match the exact product a shopper wants.
2. Product optimization
Competition on eBay is fierce. With over 1.7 billion listings, every seller on eBay will do everything to ensure that their product optimization is on point. Adding an MPN to your listings is part of product optimization. Your product won’t show up on eBay search results when a shopper uses MPN code to look for products to buy.
It is an advantage to your competitor who has done this. Even eBay search algorithms tend to favor products with MPN or any other form of identification like GTIN, EAN, or UPC.
This is because eBay is competing with other ecommerce stores like Amazon and Aliexpress. It wants to offer the best user experience, and grow and retain its users.
3. Boost visibility on search engines
An eBay product with MPN code has a better chance of appearing on search results on Google and Bing. With Google’s shopping section on searches done on mobile devices, ecommerce stores can now appear on search results for specific products shoppers look for. This can create more awareness about your store on eBay and drive more traffic to it.
4. Reduced product return
Since shoppers use MPN to search for products, they are likely to see the exact product they want to buy. This reduces the risk of buying related products which they may complain about and return.
5. Boost sales
A shopper who is using MPN to search for products on eBay is almost ready to buy. This is because they have read and researched about the product before coming to eBay with the MPN to identify it and make a purchase. This reduces cart abandonment and boosts the sales of a seller on eBay.
6. Price accuracy
For a dropshipper that uses Aliexpress eBay lister, you can avoid errors in the price tag of products since the software can add MPN, product description, and prices to corresponding products accurately at the same time.
