Overview

Getting your inventory into Amazon's fulfillment centers requires more than just packing boxes correctly — every shipment must meet specific labeling standards before it can be received and processed. Amazon enforces strict shipping label requirements for all Fulfillment by Amazon (FBA) shipments, and failing to comply can result in delays, rejected inventory, or even blocked future shipments. Whether you're sending small parcel deliveries or full truckloads, understanding these labeling rules is essential to keeping your supply chain running smoothly.

Key Points / What Sellers Need to Know

• Every box needs a unique FBA box ID label — Each box shipped to a fulfillment center must carry its own unique identifier printed directly from your shipment workflow. Labels cannot be photocopied, reused, or modified for other boxes.
• Pallet shipments require four labels — If you're shipping via less-than-truckload (LTL) or full truckload (FTL), every pallet needs four labels placed at the top center of each side.
• Label placement matters — Labels must be placed on a flat surface of the box, never on seams, openings, edges, or corners. Folded or damaged barcodes will cause processing delays.
• Both FBA and carrier labels are required — Your boxes need the FBA box ID label as well as the carrier label (UPS, FedEx, or other shipping provider), both placed where they can be easily scanned.
• Non-compliance can block future shipments — Amazon has warned that failure to properly label boxes may result in restrictions on your ability to send future inventory to fulfillment centers.

Shipping Methods and How They Affect Labeling

Amazon recognizes two primary shipping methods for inbound FBA inventory: small parcel deliveries (SPD) and less-than-truckload or full truckload (LTL/FTL) shipments. Small parcel deliveries involve items packed in individual boxes, each labeled separately for delivery through courier services or local postal carriers. These are typically smaller shipments suited for sellers who are sending limited quantities. LTL and FTL shipments, on the other hand, consolidate individual boxes onto pallets for delivery. The labeling requirements differ slightly between the two — pallet shipments carry the additional requirement of four pallet labels per pallet, positioned at the top center of each side.
