Print Amazon FNSKU labels on Zebra printers

FNSKU (Fulfillment Network Stock Keeping Unit) barcodes identify your items inside Amazon FBA. US prep centers and sellers print them on thermal stickers with Zebra desktops every day. This guide covers FNSKU product labels (not the shipping face on the Amazon box).

Typical FNSKU label size

• 2×1 or 2.25×1.25 — most common for unit labels
• 1.5×1 — smaller products / jewelry-style packs
• Use 203 DPI unless your printer is 300 DPI and you design for 300

Stock ideas: shop 2×1 and 2.25×1.25 rolls. Size chart: thermal sizes.

Workflow — Amazon export → Zebra

1. In Seller Central / your prep tool, export the shipment or listing FNSKUs with title/SKU quantities.
2. Save as CSV with columns like fnsku, title, condition, qty.
3. Open app.mylabelmaker.com.
4. Set artboard to 2×1 (or your stock size) and correct DPI.
5. Add a barcode element mapped to {{fnsku}} (CODE128 is typical) plus human-readable FNSKU text and short title.
6. Import CSV, preview, print the quantity you need (duplicate rows or print count per SKU as required by your process).

Amazon compliance tips

• Cover or remove competing scannable barcodes (UPC) when Amazon requires FNSKU-only labeling.
• Print dark, high-contrast barcodes with adequate quiet zones.
• Do not scale barcode images — use native barcode objects.
• Test-scan before labeling an entire shipment.

Hardware that works well

• 4" desktops (ZD420/ZD421) for both FNSKU and 4×6 carton work
• 2" desktops (ZD411) dedicated to product stickers
