How to make & print Amazon FBA FNSKU labels
From a single product code or an Excel spreadsheet to scan-ready stickers in three steps.
Step 1
Paste a product line or upload CSV
Enter one UPC, EAN, or Amazon X00 FNSKU code above, or upload a spreadsheet with hundreds of SKUs and quantities.
Step 2
Auto-verify check digits & quiet zones
We calculate the 12th Modulo-10 check digit and lock GS1 quiet-zone margins automatically—no pixel sliders to mess up.
Step 3
Download single PNG/SVG or 30-up PDF
Export a single sticker for free, or generate a server-calibrated Avery 5160 30-up US Letter sheet or 2" × 1" thermal roll PDF.

Clone one FNSKU × 30, or mix multiple FBA SKUs on one sheet
Restock runs are either a single product going out in one carton, or a whole catalogue at once. Both land on the same calibrated sheet: 30 identical labels, or a mixed page filled row by row from your CSV.
Clone one code across the page. A full carton of the same item: enter the FNSKU or UPC once, choose 30, and our server PDF engine returns a US Letter PDF with all 30 cells filled.
A CSV with quantities per SKU. Upload the list from your ERP — A needs 10, B needs 20 — and it is paginated, mixed and filled in order. UPC-12, EAN-13, FNSKU and GTIN-14 rows can share a sheet.
Every check digit recomputed first. A wrong Modulo-10 digit is corrected before layout and flagged in the row, so a bad code never reaches a warehouse scanner.

Amazon FNSKU barcode label FAQ
What are the 4 mandatory elements on an Amazon FNSKU sticker?
Per Amazon Seller Central Item Label Specification G200141490, every FNSKU sticker must contain: (1) a Code 128A barcode with 0.25 in left/right quiet zones, (2) the 10-character X00 alphanumeric FNSKU centered under the bars, (3) the product title, and (4) the raw item condition (such as New) at the bottom left.
Should I print a retail dollar price or 'Condition:' prefix on an FNSKU label?
No. Official Seller Central FNSKU labels print only the raw condition value (e.g., New or Used - Like New) in the bottom-left corner and never include retail prices or extra label prefixes that could interfere with warehouse optical scanners.
Can I mix multiple FNSKU codes on a single Avery 5160 30-up sheet?
Yes. While Seller Central often forces one SKU per page, our Full Sheet CSV Batch mode lets you combine e.g. 10 units of SKU A and 20 units of SKU B onto a single 30-up Avery 5160 US Letter PDF.
How much does Amazon charge if my units arrive without compliant FNSKU labels?
Amazon charges $0.55 per unit for FBA Label Service, or $0.35 to $1.50 per unit in unplanned prep service fees if barcodes fail to scan at the fulfillment center.
