How To Print And Encode Style Numbers For Shipping Labels

Style Number An identifier printed or encoded on shipping packaging for the supply-chain purpose described by 'Style Number'. When label accuracy and scan-ability are required by retailers and 3PLs, printing and encoding style numbers correctly on shipping labels prevents delays at receiving and reduces chargebacks.

Preparing shipping labels that include style numbers is a practical exercise in format discipline and technology selection. Logistics teams must decide what to print (human-readable text and barcode), which barcode symbology to use, where to place the label on cartons, and how to integrate label printing with ERP/WMS or vendor portals.

Choose The Right Barcode Symbology

Common choices for encoding style numbers are Code 128 and GS1-128. Code 128 supports compact alphanumeric encoding and scans reliably in warehouse environments. GS1-128 is a GS1-prescribed format that allows application identifiers (AIs) to tag data like GTIN, batch, and quantity on the same barcode. Use 2D codes (DataMatrix or QR) when you need to pack style number, PO, and other metadata into one symbol on limited label space.

Label Content And Formatting

Simpler is better: include the style number in human-readable text near its barcode. If the carton contains multiple SKUs or sizes, also list those attributes. Ensure contrast between barcode and background and avoid placing barcodes across box seams or on corrugated ridges. Standard label elements often include PO number, carton sequence (e.g., 2/4), quantity, and origin.

• Barcode Format: Use Code 128 or GS1-128 for linear encoding; choose DataMatrix for denser encoding needs.
• Human-Readable: Print the style number in plain text under or next to the barcode for visual checks.
• Label Size: Match label size to barcode density to keep bars and quiet zones scannable.

Integrating Printing With Systems

Label data should flow automatically from ERP, PIM, or WMS to thermal printers. Avoid manual label creation when possible: automated templates reduce typos and enforce required fields. Many retailers provide label templates or a portal where suppliers can upload ASN files and print labels that meet retailer specifications.

Printer And Consumable Considerations

Thermal-transfer printers are the industry standard for durable carton labels. They produce moisture- and abrasion-resistant prints and maintain barcode contrast on corrugated surfaces. Select label stock with adequate adhesive for rough handling and storage conditions. Test prints with handheld scanners in a representative environment before full-scale deployment.

• Printer Type: Use thermal-transfer for durable cartons; direct thermal for short-life receipts or tags.
• Ribbon And Label Supply: Match ribbon formulation to label material to prevent smudging and ensure scanability.
• Scanner Testing: Validate labels with both fixed-mount and handheld scanners used by the retailer or 3PL.

Compliance And Partner Requirements

Some retailers mandate specific label formats or symbologies. Review vendor compliance guides and test labels before shipping. Noncompliance can result in receiving delays, refusal of goods, or chargebacks. Keep records of label specifications and versioned templates available to supplier teams and packaging vendors.

Practical Workflow Example

A supplier receives a confirmed PO that lists style numbers and quantities. The ERP generates a carton manifest and label data for each carton. Labels are printed on a thermal-transfer printer using a GS1-128 barcode that encodes style number (as a non-GS1 element) and GTIN/PO via application identifiers. Warehouse staff affix labels to the largest side of each carton, scan during staging, and generate an ASN to the retailer. The retailer’s receiving team scans the barcode and matches cartons to the PO immediately, speeding putaway.

In short, the Style Number must be printed and encoded in a way that supports both machine scanning and human verification. Choose appropriate symbologies, automate label generation, and follow retailer specifications to avoid receiving issues and keep the supply chain moving.
