Pallet Labelling Systems: Complete Guide (2026 Buyer’s Guide)

If your warehouse team has ever scanned a pallet and come up empty, or received a shipment with a smeared, wrinkled label that brought your receiving line to a halt, you already understand the cost of getting pallet labelling wrong.

Pallet labelling systems are the backbone of modern supply chain operations. They ensure every unit that leaves your dock and arrives at a distribution centre can be identified, tracked, and processed without human error. In 2026, with retail, grocery, and pharmaceutical compliance requirements tightening across Canada and North America, having the right pallet labelling solution isn’t optional; it’s a competitive requirement.

This guide covers everything: what pallet labels actually contain, the GS1 and industry standards that govern them, where to physically place them, which type of pallet labellers suits your operation, and how labelling integrates with the rest of your end-of-line packaging, including your pallet wrapping machine.

1. What Is a Pallet Labelling System?

A pallet labelling system is any combination of hardware, software, and label media designed to print, apply, and verify identifying information on a pallet or the stretch-wrapped load sitting on top of it.

At its simplest, a pallet labelling system could be a warehouse printer and a person with a label gun. At the other end of the spectrum, it’s a fully automated print-and-apply labeller integrated into your conveyor line, reading real-time data from your WMS (Warehouse Management System) and applying four-sided labels at production speed.

Regardless of the technology involved, all pallet labelling solutions serve the same fundamental purpose: give every pallet a unique, machine-readable identity that can be tracked from the point of packing to the point of delivery.

This identity, typically encoded as a barcode and associated human-readable text, is what retailers, 3PLs, and distribution centres use to receive, slot, and process your goods. It’s also what regulatory bodies reference for traceability in food, pharma, and chemical supply chains.

2. What Information Goes on a Pallet Label?

Pallet labels vary by industry, trading partner, and compliance requirements, but most pallet markings contain some combination of the following data fields:

Mandatory / near-universal

•       The Serial Shipping Container Code (SSCC), the pallet’s unique ID

•       GS1 barcode (typically a GS1-128 linear barcode)

•       Ship-from address (manufacturer or 3PL)

•       Ship-to address (retailer DC or customer)

•       Purchase order (PO) number

•       Bill of lading (BOL) number

Common additional fields

•       Product description and item count

•       Lot/batch number

•       Production date and/or expiry date

•       Country of origin

•       Net weight / gross weight

•       Carrier name and route/PRO number

•       Store/DC number (required by major grocery and retail chains)

•       GTIN (Global Trade Item Number) for the items on the pallet

•       QR codes for advanced mobile scanning

Regulated industries add

•       Serialized tracking codes (pharmaceutical, DSCSA compliance)

•       UN/hazmat classification (chemicals)

•       Temperature or handling requirements

The label format most widely recognized in North American supply chains is the GS1-128 label, which organizes all of this data using standardized Application Identifiers (AIs), a coding system that tells scanners exactly what each data field means.

3. GS1 Standards and SSCC Codes Explained

What is GS1?

GS1 is a global non-profit organization that manages product and logistics identification standards. Its roots go back to 1973, when the U.S. grocery industry adopted linear barcodes to automate checkout scanning. Today, GS1 operates in over 110 countries and provides the data standards that underpin most commercial supply chains worldwide.

In Canada, GS1 Canada manages company prefix assignments and standard compliance, meaning if your company ships goods to major retailers like Walmart, Loblaw, Sobeys, or Canadian Tire, you’re almost certainly operating under GS1 standards already.

What is an SSCC?

The Serial Shipping Container Code (SSCC) is the unique identifier assigned to each logistic unit, in this context, each pallet. It is an 18-digit number. In a GS1-128 barcode the SSCC is preceded by Application Identifier (00), which tells scanners that the field that follows is an SSCC rather than a product code. The 18 digits themselves break down into four parts:

SSCC component	Description
Extension digit (0–9)	Expands the range of unique combinations available
GS1 company prefix	Your organization’s unique ID, issued by GS1
Serial reference	a unique number generated at packing time (usually sequential)
Check digit	a calculated digit that validates the SSCC hasn’t been misread

 

Think of the SSCC as a pallet licence plate. The number itself contains no product information; instead, it serves as a key that references a record in your ERP or WMS containing everything about that pallet: contents, quantity, batch, destination, and more.

GS1-128 vs. GS1 DataMatrix vs. QR Code

Most pallet labels in use today carry a GS1-128 linear barcode, the tall, narrow barcode format you’ll recognize from shipping labels. It’s fast to scan with fixed and handheld readers, and is required by most major retailers.

Increasingly, labels also carry a GS1 DataMatrix or QR code as a secondary symbology, particularly in pharmaceutical and regulated industries where more data (serialization, expiry) needs to be encoded in a compact format.

The grocery and CPG sector is part of a broader industry shift toward 2D barcodes, driven in part by the GS1 Sunrise 2027 initiative. Sunrise 2027 sets a target by which retail point-of-sale systems should be able to read 2D barcodes alongside traditional 1D barcodes. It is an industry ambition rather than a hard legal mandate, and 1D barcodes will continue to be accepted, but the momentum is pushing wider 2D adoption across supply chain labelling.

If you’re specifying new pallet labellers in 2026, make sure your print engine supports both GS1-128 and 2D symbologies to stay ahead of this shift.

4. Pallet Labelling Standards: Industry by Industry

There is no single universal pallet labelling regulation that applies to every industry everywhere. What exists instead is a patchwork of:

•  GS1 baseline standards (globally applicable, widely adopted)

• Retailer-specific compliance requirements (Walmart, Amazon, Costco, and Loblaw each have their own)

• Industry-specific regulations (CFIA/FDA for food, Health Canada/FDA for pharma, TDG for chemicals)

• Internal SOPs that your warehouse and distribution partners impose

Here’s a breakdown of the most important pallet labelling standards by sector:

Food & Beverage

Canada’s Safe Food for Canadians Regulations (SFCR) require lot-level traceability for most foods. This means each pallet must carry enough information to trace it back to the specific production batch, making SSCC, lot number, and pack date essential fields.

Major grocery retailers, including Sobeys, Metro, and Loblaw, have published their own vendor compliance guides specifying exact label formats, mandatory data fields, and label placement requirements. Failure to comply often results in chargebacks.

Pharmaceutical

The Drug Supply Chain Security Act (DSCSA) in the United States requires serialized tracking at the item, case, and pallet level. In Canada, Health Canada’s traceability initiatives mirror many of these requirements. Pharmaceutical pallet labels must include the SSCC, GTIN, lot number, and expiry date, and increasingly, a GS1 DataMatrix encoding these four data elements together.

Chemicals & Hazardous Materials

Pallets containing dangerous goods must carry TDG (Transportation of Dangerous Goods) compliant markings in Canada, including UN number, hazard class, packing group, and proper shipping name. These requirements are separate from and in addition to standard inventory labelling.

Retail / E-Commerce

Amazon, Walmart, and other large platforms publish detailed routing guides and packing standards that dictate label placement, label size (typically 4" × 6"), barcode quality grades (typically a minimum of GS1 Grade C), and specific Application Identifiers. Repeated non-compliance can result in receiving refusals or vendor fines.

Automotive

The automotive sector commonly uses AIAG (Automotive Industry Action Group) standards, which specify their own label format, barcode type, and placement rules for kanban and production pallets.

5. Seven Pallet Label Placement Rules You Must Follow

Even a perfectly printed label fails if it’s placed in the wrong location, at the wrong angle, or covered by stretch wrap. These seven placement rules apply across virtually all pallet labelling standards:

Rule 1: Apply at least two labels on opposing sides

Place identical labels on two sides of the pallet that face in opposite directions, specifically the sides accessible from the two fork entry angles. This ensures that even if one label is obscured by an adjacent pallet or warehouse racking, a scanner can still read the other.

For pallets that will be slotted into double-deep racking, apply a third label on a third face so that at least one side is always visible.

Rule 2: Labels must be vertical, no more than 5 degrees of tilt

Machine readers, fixed scanners, ASRS systems, and depalletizers are calibrated for upright labels. A label tilted more than 5 degrees from vertical can render barcodes unreadable by automated systems. Use label applicator guides or automated applicators to ensure consistent vertical alignment every time.

Rule 3: Labels must be flat, no creases, bubbles, or wrinkles

Any deformation of the label surface distorts the barcode geometry. Even minor wrinkles can cause adjacent barcode bars to merge visually, making the code unscannable. Apply labels to a smooth, dry surface and use applicators that press labels flat during application.

Rule 4: Place labels outside the stretch wrap, with one critical exception

Labels applied under stretch wrap are effectively inaccessible to most scanners. The plastic film scatters laser light and creates glare that blocks optical readers. Standard practice is to apply pallet labels after wrapping on your pallet wrapping machine. The exception: see Rule 5.

Rule 5: When pallets are unitized together, label each before wrapping

If multiple pallets are stacked and wrapped together as a single unit for transport (a common practice for lightweight goods), any labels applied to the outside of the outer wrap will be removed when the load is separated. In this case, label each individual pallet before wrapping it into the combined load, and also apply a master label to the outside of the combined unit.

Rule 6: Labels should be placed 15–45 cm from the bottom of the top board

Most major retail and distribution standards specify a placement zone: the label should sit between 15 cm (6 inches) and 45 cm (18 inches) from the floor of the pallet load, i.e., near the bottom of the stacked goods, not at floor level. This keeps labels visible whether the pallet is sitting on a dock or elevated on racking.

Rule 7: Barcodes must be high contrast, black on white

GS1 specifications and retailer compliance guides consistently require black ink on a white background for barcode zones. This maximizes contrast for both optical and camera-based scanners, and ensures readability in the variable lighting conditions of real warehouses and trailers. The human-readable text below the barcode should also be in a clean, legible sans-serif font at a minimum of 7–10 pt.

6. Types of Pallet Labelling Solutions

Not all pallet labellers work the same way. The right solution depends on your throughput, label complexity, integration requirements, and budget. Here’s how the main categories break down:

Print-and-apply (PA) systems

A print-and-apply labeller combines a thermal label printer with a pneumatic or servo applicator that places the freshly printed label directly onto the pallet or carton without human involvement. These are the workhorses of high-volume operations.

Print-and-apply systems can be configured for:

•       Tamp application (press-and-hold, ideal for flat surfaces)

•       Blow application (air-jet delivery for moving pallets)

•       Wipe application (label wiped on as the pallet passes)

They integrate with your WMS or ERP via standard data protocols, pulling live job data to print the correct label for each pallet in the sequence. Redemac carries the Evolabel print-and-apply range, a modular, compact system designed for easy installation on any production line and compatible with industry-standard labelling software, including NiceLabel and Evolabel Co-op.

Label applicators (semi-automatic)

Semi-automatic label applicators dispense a pre-printed label in the right position for an operator to apply with consistent placement. The applicator handles the peeling and positioning; the operator completes the application. This is a practical middle ground for operations with moderate volume and some variation in pallet size or configuration.

Labelling systems (automated)

Full automated labelling systems integrate with conveyor lines and are triggered by sensors or upstream signals from your WMS. They can handle multi-face application (two or three labels per pallet) and operate continuously with minimal operator involvement. These are typically deployed at the end of palletizing lines in food, beverage, and distribution environments.

Standalone label printers

Zebra and Toshiba industrial label printers (both available through Redemac) are the right choice when labels are printed at a workstation and hand-applied, as is common in lower-volume operations, receiving areas, or where pallet configurations are too varied for fixed applicators. These printers support thermal transfer and direct thermal printing at print resolutions sufficient for GS1-compliant barcodes.

Mobile label printers

For staging areas, receiving docks, or multi-site operations without conveyor infrastructure, mobile label printers allow operators to print and apply labels anywhere in the facility using a wireless connection to your WMS. Barcode verifier integrations confirm scan quality before the pallet leaves the dock.

7. Manual vs. Automated Pallet Labellers: Which Is Right for You?

This is one of the most common questions operations managers ask when evaluating pallet labelling solutions. The answer depends on four factors:

 

Choose manual / semi-automatic when

•       You palletize fewer than 30–50 pallets per shift

•       Pallet sizes and configurations vary significantly

•       You’re in a start-up or scaling phase and want to delay capital investment

•       Your label requirements change frequently

Choose automated print-and-apply when

•       You run consistent high-volume palletizing (50+ pallets per shift)

•       Retailer compliance chargebacks are a real cost concern

•       You’re already operating a pallet wrapping machine and want to integrate labelling into the same end-of-line flow

•       Your operation requires multi-face labelling for every pallet

•       Traceability and audit requirements demand a reliable, error-proof record

8. How Pallet Labelling Integrates with Pallet Wrapping

Pallet labelling and pallet wrapping are the two final steps in most end-of-line packaging operations, and the sequencing and integration between them matter significantly.

The standard end-of-line sequence

In most operations, the flow looks like this:

Pallets are built by a palletizer or manual stacking, then passed to a pallet wrapping machine, either a semi-automatic turntable wrapper or an automatic rotary arm wrapper, which applies stretch film to stabilize the load. After wrapping, the pallet moves to the labelling station where print-and-apply labellers apply GS1-compliant labels to two or three faces.

Redemac supplies both pallet wrappers (semi-automatic and fully automatic) and print-and-apply labelling systems, making it straightforward to spec and integrate a complete end-of-line solution rather than trying to connect equipment from different vendors.

Why sequence matters

As covered in the placement rules above, labels almost always need to go outside the stretch wrap so they remain scannable. If your print-and-apply station is positioned upstream of your wrapping machine, your labels will be covered. This is one of the most common and costly end-of-line layout mistakes we see in Canadian manufacturing facilities.

The ideal layout places your labelling station immediately after the exit conveyor of your pallet wrapper, with a label verifier or barcode scanner immediately downstream to confirm readability before pallets are moved to staging.

WMS integration across both systems

Modern pallet wrappers and labelling systems both offer I/O and network connectivity. A WMS-integrated line can trigger wrap cycles and label print-and-apply jobs from the same pallet ID, ensuring that the SSCC assigned to each pallet is consistent between the wrap record and the label, which is important for traceability audits.

10. Common Pallet Labelling Mistakes and How to Avoid Them

Duplicate SSCCs

Repeating an SSCC across multiple pallets is surprisingly common when labels are pre-printed in batches or when a label printer is reset incorrectly. The fix is an automated print-and-apply system that generates SSCCs from a sequentially managed pool, never reprinting the same number twice.

Labels applied before wrapping

Labelling before the pallet wrapping machine processes the load means labels end up under stretch film and can’t be scanned. Restructure your line so that labelling follows wrapping.

Wrong label for the pallet

In operations where multiple SKUs or customer-specific label formats are in use, applying the wrong label to a pallet is a chargeback risk. Poka-yoke solutions include scanners that read pallet contents or a pick label to confirm the correct label template is triggered before printing.

Poor print quality

Worn print heads, incorrect ribbon type, or wrong label media cause faded or incomplete barcodes. Establish a preventive maintenance schedule for your label printers, particularly for thermal transfer heads, which degrade with use. Redemac’s preventive-maintenance service contracts help keep your label printers in peak condition and minimize unexpected downtime.

Placement too low or at an angle

Labels placed near the floor may be obscured by pallet boards, and tilted labels will fail automated scanners. Use label applicator guides or fixed print-and-apply systems with calibrated placement heads.

Frequently Asked Questions

What size are pallet labels?

The most common pallet label size in North American supply chains is 4 inches × 6 inches (102 mm × 152 mm). Some trading partners require 4" × 8" or 6" × 8" for labels carrying more data fields. Always check your trading partners’ compliance specifications before committing to a label size.

Do pallet labels have to be GS1?

GS1 is the dominant standard, but not all pallets require GS1 compliance. Internal warehouse pallets may use proprietary barcodes. However, any pallet shipping to a major retailer, distributor, or cross-border customer almost certainly requires GS1-compliant SSCC labelling.

How many labels does a pallet need?

Most compliance guidelines require a minimum of two labels on opposing sides. Three labels are recommended for pallets destined for deep-racking storage. Some retailer programs specify the exact number and placement zone.

What is a pallet licence plate?

A pallet licence plate is another name for the SSCC barcode label, a unique identifier applied to each pallet that links to a record in your WMS or ERP describing the pallet’s contents, origin, and destination. The term is common in logistics and supply chain discussions.

Can I use a regular office printer for pallet labels?

No. Office inkjet and laser printers are not suitable for warehouse label stock, do not produce the barcode print quality required for reliable scanning, and the media is not designed for warehouse conditions. Industrial thermal label printers such as the Zebra and Toshiba models available from Redemac are the correct tool.

How does pallet labelling connect to inventory management?

Every scan of a pallet SSCC updates your inventory system: receiving, put-away, picking, staging, and shipping transactions all reference the SSCC. This creates a real-time location and movement record for every pallet in your facility, which is the foundation of effective inventory labelling and control.
