📘 US Operational Guide & Compliance Reference: Free Amazon FBA FNSKU Barcode Generator
Amazon fulfillment centers mandate Code 128 barcode symbology for all FNSKU product units. Each label must contain the FNSKU identifier, item description, and condition state (e.g., 'New'). Barcodes printed with less than 0.25 inch (6.35 mm) lateral quiet zones or optical contrast below 75% are subject to unplanned prep service fees of $$0.20$ to $$0.40$ per unit.
FNSKU Dimensions and Label Stock Options
Amazon requires fulfillment labels to measure between 1" x 2" and 2" x 3". The two standard formats across US merchant fulfillment networks are:
- Avery 5160 / 30-Up Laser Sheets: 2.625" x 1.000" (66.67 mm x 25.40 mm). Best for desktop laser and inkjet printers.
- Direct Thermal 4" x 6" or 2.25" x 1.25" Rolls: Compatible with Zebra, Rollo, and Munbyn thermal hardware. No ink cartridges required.
| Label Parameter | Amazon Requirement | SuiteCrate Default |
|---|---|---|
| Barcode Symbology | Code 128 (Subset B) | Enforced Code 128 |
| Quiet Zone (Margin) | Min. 0.25 in (6.35 mm) | Calibrated 0.28 in |
| Human-Readable Text | Title + FNSKU + Condition | Auto-truncated 3-line stack |
❓ Frequently Asked Questions
Can I use an existing UPC barcode instead of an Amazon FNSKU?
Manufacturer UPC barcodes are only permitted under commingled inventory settings. For private label sellers and brand registry protection, Amazon requires an individual FNSKU starting with X00 to prevent stock mixing.
What causes FBA scanning errors at inbound Amazon check-in?
The three most common failure points are inadequate quiet zone margins, smudged thermal printheads causing bar bleed, and selecting "Fit to Page" during printing which distorts label aspect ratios.
Does this tool support bulk printing for multi-ASIN shipments?
Yes. Paste your Amazon inbound shipment manifest with multiple FNSKUs, titles, and quantities to generate a single paginated PDF.
