Selling on Amazon involves understanding various barcodes and identifiers that play critical roles in inventory management and product tracking. These barcodes, including ASINs, FNSKUs, SKUs, and GTINs (UPC/EAN), streamline product listing, shipping, and fulfillment. By mastering Amazon’s barcode system, sellers can optimize their operations and prevent errors.
Key Amazon Identifiers
ASIN (Amazon Standard Identification Number)
- Definition: A 10-character alphanumeric code Amazon assigns to every product in its catalog.
- Purpose: Helps catalog and locate products on Amazon.
- Example: A popular book might have the ASIN “B07XQXZXJC.”
ASINs allow sellers and buyers to identify products easily within the platform’s vast inventory. Learn more about managing product listings on our Amazon Listing Optimization page.
FNSKU (Fulfillment Network Stock Keeping Unit)
- Definition: A barcode unique to your seller account for tracking FBA (Fulfilled by Amazon) inventory.
- Purpose: Links your inventory to your account and avoids commingling with other sellers’ products.
- Example: “X000123456” could represent your unique inventory item.
FNSKUs are essential for private-label sellers who want to maintain inventory integrity. Check out our guide to Amazon Account Management.
SKU (Stock Keeping Unit)
- Definition: A customizable alphanumeric code sellers create for internal inventory tracking.
- Purpose: Helps manage product variations such as size, color, or style.
- Example: “MW-16oz-Mint” might denote a 16-ounce mint-flavored mouthwash.
GTIN (Global Trade Item Number)
- Definition: A universal identifier that includes UPCs (Universal Product Codes) and EANs (European Article Numbers).
- Purpose: Used globally to identify branded products and required for most Amazon listings.
- Example: A UPC might be “012345678905.”
GTINs must come from GS1, the official organization for issuing them. Learn more about Amazon Fulfillment Processes.
Manufacturer Barcodes vs. Amazon Barcodes
Manufacturer Barcodes (Stickerless)
- How It Works: Amazon uses the product’s GTIN (UPC/EAN) for inventory tracking.
- Best For: Resellers and branded products.
- Pros:
- Eliminates the need for additional labeling.
- Works well for products with consistent GTINs.
- Cons:
- Commingling Risk: Amazon may mix your inventory with identical products from other sellers, affecting quality control.
Amazon Barcodes (FNSKU Labels)
- How It Works: Amazon assigns an FNSKU to each product, which must be labeled on every unit.
- Best For: Private-label and custom products.
- Pros:
- Prevents commingling, ensuring only your inventory is shipped to customers.
- Enhances accountability for quality and returns.
- Cons:
- Requires additional time and resources to print and apply labels.
How to Switch to Amazon Barcodes
Transitioning to Amazon barcodes offers more control over your inventory. Follow these steps:
- Enable Amazon Barcode Labeling:
- In Seller Central, navigate to Fulfillment Settings > Barcode Preference and select “Amazon Barcode (FNSKU).”
- Generate Labels:
- Download the FNSKU labels directly from Seller Central on the Inventory page. Click the three dots on the right of the product.
- Coordinate with Your Factory or Prep Center:
- Provide instructions on label placement (e.g., cover existing manufacturer barcodes).
- Use a thermal printer for high-quality, durable labels.
- Test a Small Batch:
- Ship a small batch with FNSKU labels to verify smooth processing.
Real-Life Example: Stickerless vs. Amazon Labels
Imagine selling a private-label mouthwash:
- With Manufacturer Barcodes, Amazon may commingle your inventory with another seller’s product if they use the same UPC. If their product is lower quality, customer complaints could harm your brand.
- With Amazon Barcodes, your inventory ties uniquely to your account, eliminating risks of mix-ups.
Tips for Labeling and Shipping
- Use High-Quality Labels: Ensure barcodes are clear and placed on flat, scannable surfaces.
- Avoid Duplicate SKUs: Maintain unique SKUs and FNSKUs to prevent confusion.
- Consolidate Shipments: Combine smaller shipments to save costs and minimize processing delays.
