Amazon Product Barcode, Types, Roles, and Requirements

Amazon Product Barcode, Types, Roles, and Requirements

Amazon Product Barcodes help identify, track, and manage items within its extensive database.

Different types of barcodes, such as UPC (Universal Product Code) and FNSKU (Fulfillment Network Stock Keeping Unit).

To start with Amazon barcodes, you must register your products with GS1, which manages global barcode standards. Once registered, you can create unique barcodes for your products in various formats, including EAN and GTIN-12.

Understanding Amazon Barcodes

Amazon product barcodes assist in tracking and managing products throughout the fulfillment process, from the seller to Amazon’s warehouse until it reaches the buyer.

The Universal Product Code (UPC) is an essential barcode for Amazon products. A UPC is a 12-digit code used primarily in North America to register a product and create a scannable barcode. You need a UPC barcode number to list your product on Amazon.

Another Amazon product barcode is the Fulfillment Network Stock Keeping Unit (FNSKU). The FNSKU is a unique identifier for your product when using the Fulfillment by Amazon (FBA) service. It helps Amazon correctly label and track your products in their warehouses. If selling through FBA, you’ll need to use FNSKU labels.

Different types of products require different barcodes. Amazon books, CDs, and DVDs require an International Standard Book Number (ISBN). This 10- or 13-digit number is essential for selling these items on Amazon, and obtaining an ISBN can be done in various ways.

Finally, be cautious with overlapping barcodes. Avoid applying multiple barcodes when shipping products to Amazon, which may result in errors. A common mistake is using both UPC and FNSKU barcodes on a product. Cover the UPC barcode with the FNSKU when using FBA to avoid this.

Types of Barcodes Used in Amazon

What is  Amazon Seller SKU

UPC Barcodes

UPC Barcodes, or Universal Product Codes, are commonly used in the United States for identifying retail products. When you list a product on Amazon, they typically require a unique, valid UPC barcode for each product variation, such as size or color. Applying a UPC barcode to your product ensures accurate identification and tracking in the Amazon marketplace.

EAN Barcodes

European Article Numbers (EAN) are similar to UPC barcodes but used predominantly in Europe. They play the same role in identifying retail products, and Amazon equally accepts EAN barcodes for product listings. It’s essential to have a unique EAN barcode for every product variation you intend to sell to avoid any mix-ups in the inventory.


The Amazon Standard Identification Number (ASIN) is a unique 10-digit alphanumeric code assigned to products on Amazon’s marketplace. Every product listed on Amazon has an ASIN to help customers and sellers identify the correct item. Unlike UPC and EAN barcodes, ASINs are exclusive to Amazon, which doesn’t apply to other retail platforms.

FNSKU Barcodes

Amazon FNSKU

Fulfilled by Amazon (FBA) sellers often use FNSKU (Fulfillment Network Stock Keeping Unit) barcodes for their products. FNSKU barcodes are unique identifiers Amazon assigns to products stored in their fulfillment centers. Using FNSKU barcodes helps ensure the correct product is picked, packed, and shipped to customers when ordering.

Role of Barcodes in Amazon FBA

Inventory Management

As an FBA seller, you must have proper Amazon product barcodes that adhere to Amazon’s guidelines. These include UPC, EAN, and GTIN codes for product identification. Additionally, you’ll need to use Amazon’s FNSKU barcodes, which are unique to your products and account, to ensure accurate inventory tracking.

Staying organized with barcodes allows Amazon to allocate the correct products to the right customer orders. This will prevent errors when fulfilling your orders and simplify the returns process if necessary.

Product Labeling

Proper labeling is crucial when selling on Amazon FBA. Your products must be labeled with the necessary Amazon product barcodes in their retail packaging or possibly on the product itself, depending on your specific product type and business model. This ensures that Amazon can efficiently locate, handle, and ship your items to customers.

Adhering to labeling guidelines helps you maintain a professional image and prevent customer complaints due to incorrect items being shipped. Make sure all labels are scannable and visible on your packages.

Suspension and Renewal

Non-compliance with Amazon’s barcode and labeling system can lead to account suspension. Accounting for all barcodes, including UPC, EAN, FNSKU, and GTIN (if applicable), is essential. These codes are also crucial when renewing your listings or extending your product offerings on Amazon FBA.

If you face an account suspension, promptly reviewing and rectifying any issues related to barcodes or labeling will increase the likelihood of your account being reinstated. Meeting Amazon’s requirements throughout your sales process keep you in good standing as an FBA seller.

Amazon Product Listing and Barcode Requirements

Listing your products on Amazon requires following certain guidelines to ensure a smooth selling experience. One crucial aspect is understanding and adhering to Amazon’s barcode requirements.

To successfully list a product on Amazon, you need a unique identifier, such as a Universal Product Code (UPC), European Article Number (EAN), or Global Trade Item Number (GTIN). These codes are essential for proper product identification and management within the Amazon marketplace.

If your product doesn’t have a manufacturer barcode or isn’t eligible, Amazon requires Fulfillment by Amazon (FBA) sellers to obtain an Amazon-specific barcode called a Fulfillment Network Stock Keeping Unit (FNSKU). This barcode is unique to your product and limited to Amazon’s use only.

Here are some important tips to consider when dealing with Amazon barcodes:

  • Ensure that each product variation has a unique barcode. Differences in size, color, or package quantity all require distinct identifiers.
  • Based on Amazon’s guidelines, place the barcode on the retail packaging of your product or sometimes on the product itself.
  • Always keep your barcodes clear and scannable to prevent any issues with inventory management or order fulfillment.

Amazon’s product barcode requirements help make your product listings compliant and reduce the risk of potential inventory or sales issues. By following these guidelines and understanding the necessary information about UPC, EAN, GTIN, and FNSKU codes, you can confidently manage your Amazon product listings and ensure a smoother selling experience for you and your customers.

Creating and Obtaining Amazon Product Barcodes

UPC Codes Registration

To acquire a UPC for your Amazon products, register with the GS1 organization. As a seller, it’s crucial to have authentic UPCs for each product variant, including color, size, and material. Registering with GS1 grants you access to unique product codes essential for managing your inventory and distinguishing your products from others.

GS1 and GTIN Standards

The GS1 organization is known for creating a standardized system of unique identifiers, Global Trade Item Numbers (GTINs). GTINs and UPCs serve as the foundation for identifying products across international markets. GS1 upholds strict regulations for correct use to ensure data accuracy and prevent duplicate UPCs from entering the market. Abiding by GS1 and GTIN standards helps businesses maintain transparent product listings and accurate inventory tracking.

GTIN Exemption

In some cases, your Amazon products may not require a conventional GTIN. You can apply for GTIN exemption if your item falls under one of Amazon’s accepted categories. Examples include handmade products, private label items, or instances where you cannot obtain a GTIN from the manufacturer. GTIN exemption allows you to list these products on Amazon without the standard barcodes. Check Amazon’s guidelines for details regarding the GTIN exemption process.

Register your UPCs correctly and acquaint yourself with GS1 and GTIN standards as you build your Amazon product listings. In scenarios where GTIN exemption applies, follow Amazon’s guidelines to ensure seamless listing and inventory management.

Private Label and Branded Products

Scannable Amazon Product Barcodes

Scannable barcodes are crucial when selling private label and branded products on Amazon. They help Amazon track your inventory and ensure the correct product is shipped to customers. There are two common scannable barcodes: manufacturer’s barcodes and SKU labels.

Manufacturer’s Barcodes

Manufacturer’s barcodes, also known as UPCs, are unique to each product and assigned by the product’s manufacturer. When selling branded products on Amazon, you typically use the pre-existing UPC provided by the brand. With private label products, you’ll need to purchase a UPC through an organization like GS1, which oversees the global allocation of authentic product barcodes.

FNSKU Labels

FNSKU (Fulfillment Network Stock Keeping Unit) labels are specific to Amazon and assigned to products when sold using the Fulfillment by Amazon (FBA) service. Also known as the Amazon barcode, FNSKU labels on your product identify and connect to your Amazon Seller account. This ensures that your inventory is properly tracked within Amazon’s warehouses.

Manufacturer’s barcodes are primarily used for branded products, while private label products require a unique UPC from GS1. FNSKU labels are exclusive to Amazon FBA and help manage inventory effectively.

Importance of Physical Stores and Retailers

In today’s digital age, one might assume that brick-and-mortar stores are losing significance. However, physical stores remain an important aspect of the modern retail landscape. Even online retailers like Amazon are opening physical stores. Let’s explore the reasons behind their sustained relevance.

Firstly, physical stores offer a sensory experience that online shopping cannot replicate. You can feel the texture of an item, try it on for size, or assess its color firsthand. This tactile interaction gives you confidence in your purchase and reduces the chances of dissatisfaction or returns.

Moreover, shopping in-store allows for instant gratification. You can take home your purchase immediately, avoiding the wait for an online delivery. This also eliminates any shipping and handling fees often associated with online orders.

Furthermore, customer service is a key factor in the continued importance of physical stores. Store employees can provide personalized assistance, answering questions and offering recommendations tailored to your needs. This level of support is difficult to replicate online and can be a deciding factor when purchasing.

Physical retailers also contribute to local economies by creating jobs and generating community investments. Supporting local businesses is a priority for many consumers, who value the positive impact of their shopping decisions on their communities.

Regarding barcodes on Amazon, physical retailers play a crucial role by demanding suppliers to include UPCs on their products to manage inventory efficiently. Amazon and other online retailers also require this system for tracking products, proving the interdependence of online and physical retail.

Considerations for New Sellers

As a new seller on Amazon, it’s crucial to understand the importance of barcodes for your products. Amazon requires that all products have a barcode, usually a Universal Product Code (UPC) before you can list and sell them on the platform source. To help you get started, here are some key points to consider.

Firstly, you must register your brand and obtain selling privileges on Amazon. This will determine whether you choose an Individual or Professional level account. Each level comes with fees and support options, so carefully analyze your estimated sales volume and business needs before deciding.

Next, keep in mind the extra costs associated with barcodes. When selling on Amazon, you must assign a unique UPC to each product or variation. For example, you’ll need nine unique barcode sources if you have a shirt in three colors and sizes. To avoid potential issues with counterfeit or reused barcodes, purchase them from a reputable source.

Understanding your product’s barcode structure is also beneficial. The first digit of a UPC indicates the product type, while digits 2-6 represent the brand or manufacturer number. Familiarity with your product’s barcode can help you smoothly manage inventory and avoid mistakes in product listings.

Lastly, don’t forget about Fulfillment by Amazon (FBA) requirements. To use FBA, you must generate an Amazon-specific barcode called FNSKU and place it on your product or packaging source. This will enable Amazon’s fulfillment center to handle and track your items properly.

Packaging and Labelling Tools

Thermal and Laser Printers

FBA Packaging and Labelling Tools

Thermal and laser printers can be used when printing barcode labels for Amazon products. Thermal printers utilize heat to produce labels and are known for their high-speed printing capabilities, whereas laser printers use toner and are well-suited for printing detailed labels with crisp, clear text.

For instance, the Phomemo M220 Label Maker is a Bluetooth-enabled thermal label printer suitable for barcode, address, and folder labeling. On the other hand, Amazon suggests using Avery 1″ x 2-5/8″ labels that are compatible with laser printers for printing barcodes on matte white removable labels.

Label Service

Besides printing labels on your own, a label service provider can be a convenient option. Label service providers create and print barcode labels and offer formats such as Amazon FNSKU barcodes, UPC, or EAN. This can save you time and resources and ensure precise, professional-quality labels for your Amazon products.

Barcode Scanners

A barcode scanner speeds up the inventory process and manages product data accurately. Barcode scanners come in various forms, including handheld devices and stationary scanning solutions. They read barcode labels on products and communicate product information to your inventory software or computer system. This allows efficient tracking, sorting, and managing your Amazon products during packaging and labeling.
