Navigating Amazon's barcode requirements can be challenging for sellers. With multiple options available—manufacturer barcodes, Amazon barcodes, and Transparency codes—it's crucial to understand their differences and applications to optimize your fulfillment process.
1. Amazon Barcodes: The Electronic Product Identity
Amazon Barcodes (also called FNSKU labels) serve as unique identifiers for products in Amazon's fulfillment network. These codes, typically beginning with "X0," function as digital fingerprints for inventory tracking. Sellers must apply these labels when choosing not to use manufacturer barcodes for product identification. While sellers can print and apply these labels themselves, Amazon also offers paid labeling services through FBA.
2. Manufacturer Barcodes: The Original Product Identifier
Manufacturer barcodes (UPC or EAN codes) represent the standard product identification system used globally. These pre-existing codes simplify listing setup but come with an important consideration: using manufacturer barcodes means participating in Amazon's commingled inventory program, where identical products from different sellers may be stored together.
3. Transparency Codes: Anti-Counterfeiting Protection
Amazon's Transparency program provides unique verification codes marked with a distinctive "T" logo. These codes serve as anti-counterfeiting measures, allowing brands to authenticate products and protect their intellectual property. Transparency codes must remain unobstructed by other labels and clearly visible for scanning.
4. When Amazon Barcodes Are Mandatory
Certain product categories require Amazon barcodes instead of manufacturer codes:
- Topical products: Skincare, cosmetics, and haircare items that directly contact consumers
- Perishable goods: Food, medicine, and other time-sensitive products
- Consumer packaged goods: High-volume items like cleaning supplies and personal care products
- Products with unscannable original barcodes: Items where manufacturer codes become illegible after packaging
5. Obtaining Amazon Barcodes
Sellers can acquire Amazon barcodes through two primary methods:
- Inventory Management: Navigate to "Manage Inventory" in Seller Central, select products, and choose "Print Item Labels" from the action menu
- Shipment Creation: During FBA shipment setup, access the "Label Items" section to generate printable files compatible with either thermal or laser printers
6. Choosing Between Barcode Types
Consider these factors when selecting barcode options:
- Availability and scannability of existing manufacturer codes
- Product category requirements
- Inventory commingling preferences (manufacturer codes enable shared inventory)
7. Barcode Application Best Practices
Ensure proper label implementation by following these guidelines:
- Maintain high print quality for optimal scanning
- Use Amazon-recommended label dimensions
- Select durable label materials to prevent damage during transit
- Apply labels to flat, unobstructed packaging surfaces
8. FBA Labeling Services
For sellers preferring not to handle labeling, Amazon provides professional barcode application services for a fee. This optional service can streamline operations and reduce logistical burdens.
Mastering Amazon's barcode system enables sellers to enhance operational efficiency, comply with platform requirements, and potentially improve inventory management. Proper implementation of these identification systems forms a foundation for successful marketplace participation.
