amazonfbashippinglabels are required for each unit or box sent to Amazon’s fulfillment centers. These labels contain critical data like barcodes (FNSKU or UPC), which Amazon uses to track and manage inventory. Incorrect or missing labels can cause delays, lost inventory, or additional fees. Sellers can print these labels themselves or use Amazon’s Label Service for a fee. Understanding label placement, format, and compliance is vital to maintain shipment accuracy and account health. A small oversight in labeling can lead to significant operational setbacks.
