Amazon fulfilment centres scan every unit. When a label can't be read, your stock may be delayed or relabelled for a fee. Most problems come from a few simple mistakes.
Scaling shrinks the barcode and moves labels off the sheet. Always print at 100%.
If the product's UPC or EAN is still showing, the wrong code may be scanned. Cover it with the FNSKU label.
Every sellable unit needs its own label - count your units, not your products.
Low toner and worn thermal heads make bars hard to read.
Labels too small for the barcode, or text that runs off the label.
The FNSKU label generator draws sharp vector barcodes with the required clear margin, shortens long titles to fit, and prints the right number of labels for each product from your shipment list.
Print at actual size, one label per unit, with only one barcode visible. These habits keep your FBA shipments moving without extra fees.
