GS1-128 / SSCC
GS1 pallet & carton logistics labels
Applies to — Pallet & carton labels for retail supply chains
GS1-128 is a supply-chain barcode that encodes multiple data fields; the SSCC is an 18-digit unique ID for a pallet or carton. Major retailers require pallet and carton labels to follow GS1 standards, with fixed label zones and a minimum print grade. For the material, a 4×6 direct-thermal label suits short-term indoor shipping, while thermal-transfer with a wax-resin ribbon gives weatherproof pallet labels.
What it is
GS1-128 is the barcode symbology that carries multiple logistics fields (the SSCC, plus lot, quantity, dates and more). The SSCC — Serial Shipping Container Code — is an 18-digit “licence plate” that uniquely identifies a pallet or carton through the supply chain.
What retailers require
Major retailers require pallet and carton labels to follow GS1 standards: the GS1 Logistic Label guideline fixes label zones and placement, and print quality should grade at least 1.5 (ANSI C) under ISO/IEC 15416 on a white background so scanners read it reliably. Design to GS1 from the start if you ship into big-box retail.
What material to use
A 4×6 direct-thermal label works for short-term indoor shipping (no ribbon, print on demand). For weatherproof pallet labels that must survive the yard and the supply chain, use thermal-transfer with a wax-resin ribbon. Match the material to how long — and in what conditions — the barcode must stay scannable.
Common questions
Answered
straight.
What is an SSCC?
The Serial Shipping Container Code — an 18-digit unique identifier for a pallet or carton, carried in a GS1-128 barcode. It acts as the "licence plate" that tracks a shipping unit through the supply chain.
What label do retailers require on pallets?
A GS1-compliant label: a GS1-128 barcode with the SSCC, printed to at least a 1.5 (ANSI C) grade and placed in the GS1-specified zones. Use direct-thermal for short-term indoor shipping or thermal-transfer wax-resin for weatherproof pallet labels.
General guidance — not legal advice
This is a plain-English overview to help you ask the right questions — not a legal opinion or a compliance certification. Requirements change and depend on your specific product, market, and packaging. Always confirm with your supplier’s compliance documents and, where it matters, a qualified regulatory advisor.
