Understanding Amazon FBA labeling requirements<\/h2>\n\n\n\n

Selling through Fulfillment by Amazon (FBA) can help simplify order fulfillment, but it also comes with specific labeling requirements. Every product sent to an Amazon fulfillment center must have the correct labels applied and placed properly so it can be received, tracked, and shipped accurately.<\/p>\n\n\n\n

Understanding Amazon\u2019s labeling requirements can help you avoid fulfillment delays, relabeling fees, and rejected inventory. Whether you\u2019re using barcode labels, shipping labels, or compliance labels, knowing which labels you need and where to place them is key.<\/p>\n\n\n\n

What labels are required for Amazon FBA?<\/h2>\n\n\n\n

Amazon requires every product sent to a fulfillment center to be properly labeled so it can be received, tracked, stored, and shipped accurately. The labels you need will depend on your product, packaging, and fulfillment setup.<\/p>\n\n\n\n

Most Amazon sellers use some combination of the following labels:<\/p>\n\n\n\n

Product barcode labels<\/h4>\n\n\n\n

Every item sent through FBA must have a scannable barcode. Depending on your product and inventory settings, this may be an Amazon barcode (FNSKU) or a manufacturer barcode, such as a UPC. Barcode labels help Amazon identify your products and ensure you receive credit for each sale.<\/p>\n\n\n\n

Shipping labels<\/h4>\n\n\n\n

Each shipment sent to an Amazon warehouse requires shipping labels generated through Amazon Seller Central. Every box must have a unique shipment label, and palletized shipments require pallet labels that meet Amazon’s requirements.<\/p>\n\n\n\n

Suffocation warning labels<\/h4>\n\n\n\n

Products packaged in poly bags with openings 5 inches or larger, measured when flat generally require a suffocation warning label. Amazon specifies minimum font sizes based on the size of the bag.<\/p>\n\n\n\n

Sold as set labels<\/h4>\n\n\n\n

If multiple items are sold as a single unit, they must be packaged together and labeled as a set to prevent them from being separated during fulfillment.<\/p>\n\n\n\n

Expiration date labels<\/h4>\n\n\n\n
\"Expiration<\/figure>\n\n\n\n

Products with expiration dates must display the date on both the individual unit and the outer carton using Amazon-approved date formats. For most products, dates must be in MM-DD-YYYY or MM-YYYY format. If your packaging uses a different format, cover it with a correct label.<\/p>\n\n\n\n

Amazon also has other specific requirements for expiration-dated inventory,<\/a> including product preparation guidelines. Sellers should review these requirements before shipping products with expiration dates.<\/p>\n\n\n\n

Transparency labels<\/h4>\n\n\n\n

Some brands enrolled in Amazon Transparency <\/a>use unique authentication labels to help prevent counterfeit products and protect brand integrity.<\/p>\n\n\n\n

The exact labels you’ll need depend on the type of products you sell and how they’re packaged. Taking the time to understand Amazon’s labeling requirements can help ensure your inventory arrives ready for fulfillment and moves through Amazon’s network without unnecessary delays.<\/p>\n\n\n\n

Amazon FBA barcode labels: FNSKU vs. UPC<\/h2>\n\n\n\n

Every product sent to Amazon FBA must have a readable barcode. Depending on your product and fulfillment settings, Amazon may require an Amazon barcode (FNSKU) or allow a manufacturer barcode, such as a UPC.<\/p>\n\n\n\n

\n

What is an FNSKU?<\/h3>\n<\/div>\n\n\n\n
\"Example<\/figure>\n\n\n\n

An FNSKU (Fulfillment Network Stock Keeping Unit) is an Amazon barcode that identifies both a product and the seller who owns the inventory. Amazon uses FNSKUs to track products throughout its fulfillment network and ensure the correct seller receives credit for each sale.<\/p>\n\n\n\n

Many sellers choose FNSKU labels to keep their inventory separate from similar products sold by other sellers. FNSKU labels are commonly used for private-label products and stock that requires Amazon barcode labeling.<\/p>\n\n\n\n

What is a UPC?<\/h3>\n\n\n\n

A UPC (Universal Product Code) is a manufacturer barcode used to identify a product regardless of who sells it. Some Amazon sellers use UPCs as their product barcode, while others use FNSKU labels to help keep their inventory separate from similar products sold by other sellers.<\/p>\n\n\n\n

Understanding Amazon barcode types<\/h4>\n\n\n\n

Not sure whether to use an FNSKU or UPC? Choosing the right barcode can affect how Amazon tracks inventory and identifies products throughout the fulfillment process.<\/p>\n\n\n\n

This guide explains the differences between common Amazon barcode types, including FNSKUs, UPCs, ASINs, and GTINs, so you can determine which option is right for your products.<\/p>\n\n\n\n

Depending on your product and fulfillment settings, Amazon may require an FNSKU label or allow you to use an existing manufacturer barcode.<\/p>\n\n\n\n
