Code128 vs EAN-13: Which Barcode Should You Use?

Choosing the right barcode format matters. A barcode that works for internal warehouse labels may not be accepted for retail product packaging, and a retail barcode may be too restrictive for internal stock labels. This guide explains the practical difference.

What is Code128?

Code128 is a flexible barcode format that can encode numbers, letters, and many symbols. It is commonly used for internal inventory labels, warehouse locations, picking labels, shipping references, asset tags, and small business product labels.

Because Code128 accepts alphanumeric values, it works well with SKUs such as WINE-DE-2026-001, BOX-A12, or SKU-RED-XL.

What is EAN-13?

EAN-13 is the standard barcode format used on many retail products worldwide. It contains exactly 13 digits and is often connected to official product identification systems. If a product will be sold through a retail chain or marketplace that requires official GTIN/EAN codes, EAN-13 is usually the expected format.

Quick comparison

• Use Code128 for internal SKUs, stock labels, shelf labels, bins, and warehouse workflows.
• Use EAN-13 for official retail product barcodes where a 13-digit product code is required.
• Code128 can contain letters and numbers; EAN-13 is numeric and fixed length.
• Code128 is more flexible; EAN-13 is more standardized for retail packaging.

Which one does BarcodeMaker use?

BarcodeMaker currently creates Code128 labels because it is the most useful format for spreadsheet-based label workflows. It works with SKUs, custom product IDs, warehouse locations, and mixed text values. EAN-13 support can be added later for sellers who need strict retail barcode output.
