How to Add Products on Amazon Seller Central

Many new Amazon sellers have a common question: “How do I add my products in Seller Central?” It’s an understandable one — navigating through Amazon Seller Central can be intimidating when you sign in for the first time. 

Whether you’re creating a new product detail page from scratch or listing your product on an existing Amazon ASIN, adding products is something all sellers need to know how to do. 

In this article, we’ll go over adding products to an existing listing and creating a brand-new product listing in Amazon Seller Central.

How to list items on Amazon: the two ways

Listing products on the platform is a process that may sound confusing but I promise, it’s straightforward. 

If you are in the reselling business through models such as retail arbitrage, online arbitrage, wholesale, or through books, you’re likely reselling products that already exist on Amazon. 

This means that you don’t have to create a brand new listing from scratch because Amazon does not want duplicate listings of products for sale. If you resell other brands’ products, your offer will be on the same listing as other sellers’. 

For example, if you search for a product on eBay, you will likely see multiple listings for the same product. Whereas on Amazon, you’ll only see one listing.

If you are selling a private label product (or a product not yet on Amazon) you will need to create a brand new listing, which requires a few more steps. 

Stay with me; I’ll go over how to do both.

How to add a product to an existing Amazon listing 

If you are selling books or selling products through arbitrage or wholesale, here’s how to list your product for sale when the same product already exists on Amazon. 

For this example, let’s say you have a wholesale account with a brand that sells dog treat bags, and there’s already an active listing for that exact product on Amazon. 

Step 1: Get the ASIN of the product you want to sell

You can find the ASIN (Amazon Standard Identification Number) in the listing URL or under “Product details.” 

Note: if you are selling a product with multiple variations, make sure you are on the correct variation before copying the ASIN. 


Step 2: Go to Catalog, then click on “Add Products” in Seller Central and search for the ASIN

Step 3: Choose the condition of the item and click “Sell this product”

Step 4: Create your offer

In this step, enter your selling price (Standard Price) and item condition (Offering Condition Type), then choose between two options for your Fulfillment Channel: Merchant Fulfilled (FBM) or Fulfillment by Amazon (FBA). If you select Merchant Fulfilled, another option will prompt you to add the quantity. If you choose Fulfilled by Amazon, the prompt will redirect you to create an FBA shipment

“Contribution SKU” is a unique product identifier that only you will see. The SKU is usually used to help you keep track of inventory. For the product above, for example, you can make the SKU something like “DG_Pouch_01.” This section is optional and if you do not choose your own SKU, Amazon will assign you one at random. 

Once you have added your information, click on “Save and finish” at the bottom. 

Your product will now be added to your “Manage Inventory” section in Seller Central.

If you’re using FBA as your fulfillment method, your listing will become active once Amazon receives your inventory.

How to create a brand-new Amazon listing

If you are selling a product that is not yet listed on Amazon, here is how to list an item on Amazon.

Step 1: Go to “Add a product” in Seller Central

Then click on “I’m adding a product not sold on Amazon.”

Step 2: Select your product category

Step 3: Enter your product information 

In this next section, you will enter all of the information about your product, such as the Product Name (title), price, brand name, manufacturer, product ID, images, fulfillment, and so on. 

When entering your product ID, such as a UPC barcode, make sure you purchased it from GS1. Amazon will verify with GS1 that your UPC is legitimate.

Once you fill in all the necessary information about your product, click on “Save and finish.” Now your product will be listed on Amazon!

How to add products via upload

If you are uploading multiple products simultaneously, using a product spreadsheet is an excellent method. If you are not very familiar with Amazon Seller Central, I would not recommend this method of adding products.

Uploading an inventory file to Seller Central can be challenging, so only use this method if you are proficient in spreadsheets. 

Step 1: Go to “Add products via upload” in Seller Central

Step 2: Follow the steps Amazon lays out

First, choose a template to get started. Next, choose the marketplace you need a spreadsheet for and download it.

The template will download and you can upload into a spreadsheet program.

Step 3: Open your template in a spreadsheet program

Once you generate your template, open the file in Excel or Google Sheets. In the sheet, you will see multiple tabs at the bottom. 

Find the instructions on how to fill out the template, definitions, examples, and the template to be filled out. 

Read the directions carefully and check out Amazon’s example templates if you have trouble filling out specific columns. Amazon also shows an example of adding a product with variations called a parent-child listing. 

Step 4: Fill out the template with your product information

Step 5: Upload your file to Amazon Seller Central

Once you fill in your spreadsheet, download the file and head back to Seller Central. 

In the same section where you generated the template, choose “ Upload your inventory file” at the top of the page. 

Add your file, and Amazon will begin processing your spreadsheet. Uploading takes some time; Amazon allows you to enter your email address so you can receive a notification once your file upload is complete.

You can also monitor the status of your spreadsheet by clicking on the “Spreadsheet upload status” tab. 

If your file has any errors, Amazon will let you know what you need to do to correct them.

  1. Hi, I’m selling used books on FBA. Do I use my original SKU I created for each book when I restock a title? Or do I create a new SKU with each restock shipment? Thanks!

  2. Great article. Loved it.

    How can I sell a product already listed but with my own brand. Somebody imports the same product from Chine as the one I got, and I am not able to upload my listing. So if I use the existing ASIN, is it possible to get my own description and brand name? Also, I have more variations than the existing one, so how could I be able to sell all the other variations. I have already bought

    1. Hi Ricardo,

      You cannot list your product on another brands listing. You will need to create your own listing for your brand and variations.

  3. Hello Brian!

    I need help.
    I’m a newbie working with online arbitrage FBA and wanted to join an existing listing. Applied for sale permit, received approval.
    I ordered a product, it has already arrived at the prep center, but when I add the product to the inventory, I do not have active buttons and writes: “Not available”.

    How to solve this problem??
    Thank you

  4. Hi Brian. I am a new seller on Amazon and I would like to know how to send items already listed in Amazon to FBA. I created a listing for the item already and it happens to be branded. Any suggestions would be helpful. Thank you.

  5. I have notebooks I’m going to sell on Amazon. All the notebooks are the same but the color. I have five colors so I bought 5 GTIN barcodes on GS1. How do I list the product? Once I do, how do I send my product to FBA?

  6. Hello !

    I am launching my very first product on Amazon.

    I have a question about the “Brand name” space.

    I don’t have a trademark yet. Can I give a name (new Brand Name) to my product, to put on it as Amazon requires and this will be ” Brand name”?

    No need at this point to register a trademark, right ?

    I don’t want to sell under “generic” because I want my product to be protected at least with a Brand Name.

    Could you please clarify this point ? Thank you !

    1. Hi,

      Yes, you can add any brand name you wish to your Amazon listing, but Amazon will likely require proof. Meaning they will need to see a photo of the product or packaging with the brand name affixed to it. You do not need to get a trademark to use your brand name.

  7. Hi Brian, well done. Can I ask, I am new to Amazon, and I am listing my products that we make ourselves, so new product listings. But I have made some mistakes, now I have deleted them all and want to start again. Can i still add them as new listings or will Amazon remember? I need to still use me barcodes and sku numbers. Thanks for any help, I tried to add one product again but it said.. is your product that same as (and showed me my old listing) 😩

    1. Hi Stephie,

      If you already added the product in Seller Central, there is no true way to delete it from Amazon. You must use that old listing. What was the mistake, and why did you need to delete it? What couldn’t you have fixed? It isn’t very difficult to change a listing even if you made a mistake.

  8. Hi Brian
    Does UPC is necessary for the products to bne listed or ASIN will work well.
    What is the procedure to list product that is already listed on amazon.

    1. Hi Abdul,

      If the product is already listed on Amazon, you use the ASIN of that product to list it in Seller Central. You can also use the products UPC, but not necessary.

  9. Hi Brian, I’ve been trying to upload my product line into the Amazon Seller Central catalogue for about 2 months. I tried adding one by one which did not went well and then uploaded at least more than 20 excel files where I ALWAYS get errors. It’s a very frustrating process and Amazon does not support us in detail. Mostly they answer the phone and then send you an automated reply to fix your error. Do you know any company that does the upload or can help me to upload?

    1. Hi Sol,

      Have you tried uploading them manually instead of using an excel file? Follow the steps in this article. If you still have trouble, search for Amazon freelancers on sites such as Upwork who will be able to help you upload your products.

  10. I sell my products locally but wondering how I can sell them using Amazon. This article cleared all my doubts. Thank you for such informative article. Keep adding more such articles.
