Applying FNSKU labels correctly is a critical step when preparing items for Fulfillment by Amazon (FBA). Proper labeling ensures your inventory is received, tracked, and fulfilled accurately by Amazon.
🏷️ Why Proper Labeling Matters
Incorrectly applied labels can lead to:
Inventory being rejected at the warehouse
Delays in receiving your shipment
Misplaced or unscannable items
Additional fees or relabeling by Amazon
Taking a few extra seconds to label items correctly can save hours of troubleshooting later.
📦 When to Apply FNSKU Labels
You should apply FNSKU labels:
After creating your shipment
Before packing your items into boxes
Before sending inventory to Amazon
👉 Every unit must have a scannable FNSKU barcode.
🧾 Step-by-Step: Applying FNSKU Labels
1. Print Your Labels
Download your FNSKU labels from your listing or shipment workflow. Make sure you’re using the correct label size for your printer.
2. Cover Existing Barcodes
If your product already has a manufacturer barcode (UPC/EAN), completely cover it with the FNSKU label.
👉 This prevents Amazon from scanning the wrong barcode.
3. Place the Label Correctly
Apply the label on a flat surface
Avoid edges, corners, or curved areas
Do not place over seams or openings
4. Ensure It’s Scannable
Barcode should be clear and not smudged
No wrinkles or air bubbles
Fully visible (not cut off)
⚠️ Common Mistakes to Avoid
Placing labels over uneven surfaces
Leaving old barcodes exposed
Printing incorrect sizes or low-quality labels
Using damaged or faded labels
💡 Pro Tips
Use a thermal printer for consistent quality
Test scan a label before shipping
Keep labels organized per batch
Label items as you process them to avoid mix-ups
✅ Summary
Applying FNSKU labels properly ensures your inventory is received and tracked correctly by Amazon. Clean, accurate labeling helps prevent delays, errors, and extra fees—making your FBA workflow smoother and more efficient.
