How to Print Amazon FBA Labels the Right Way
Beginner’s Guide to Amazon FBA Label Printing
If you’re new to selling on Amazon FBA, one of the first things you’ll need to master is labeling your products correctly. Amazon is strict when it comes to label placement, sizing, and print quality, and getting it wrong can lead to delays, extra fees, or even rejected shipments.
But don’t worry. In this guide, we’ll walk you through every type of label you might need, how to print them properly, and which printer we recommend for a smoother FBA workflow!
The 4 Main Types of Amazon FBA Labels
1. FNSKU Labels (Individual Product Labels)
These are the individual barcodes that identify each unit you send to Amazon. You’ll need to apply one FNSKU label to every product unless Amazon has told you otherwise.
When You Need Them: Always, unless you’re enrolled in Amazon’s system where your items don’t need labels
Size Requirements: Typically 1" x 2-5/8" or 2" x 1"
Label Must Be: Black and white, scannable, and not faded or smudged
2. Shipping Labels
Each box you send to Amazon needs a shipping label that includes both the carrier’s barcode and Amazon’s shipment ID.
Label Size: 4" x 6"
Where to Place: Flat surface on the box, never over seams or corners
Make Sure: There’s one label per box and it’s fully visible
3. Warning Labels
Amazon requires suffocation warning labels on poly bags with openings larger than 5 inches. These can be printed or pre-printed, but they must be clearly visible.
Example: “WARNING: To avoid danger of suffocation, keep this plastic bag away from babies and children.”
4. California Proposition 65 Labels
If you’re selling or shipping certain products to California, you might need to add Prop 65 warning labels.
When Required: Products that contain chemicals on California’s Prop 65 list
The Best Way to Print Amazon Labels
Thermal printing is Amazon’s preferred method for label production, and for good reason:
No ink or toner: No smudging or fading
Fast and reliable: Ideal for bulk label runs
High clarity: Ensures scannable barcodes every time
While you can use a laser printer and 8.5" x 11" label sheets, thermal printers are more efficient, especially as your business grows.
