What Is GS1 Barcode

June 23, 2026

What Is a GS1 Barcode?

A GS1 barcode is a globally standardized barcode format developed by GS1, an international organization responsible for creating universal product identification standards.

GS1 barcodes store product information in a machine-readable format that can be scanned using barcode scanners, mobile devices, or POS systems.

Businesses use GS1 barcodes to:

Identify products
Track inventory
Improve logistics
Simplify retail operations
Support global commerce
Improve supply chain visibility

GS1 standards ensure that products can be recognized consistently across different retailers, marketplaces, warehouses, and distribution systems.

Why GS1 Standards Are Important

Without standardized barcode systems, businesses would struggle with:

Inventory inconsistencies
Duplicate product identifiers
Supply chain confusion
Retail integration issues
Product tracking limitations

GS1 standards solve these problems by creating a universal identification framework used globally.

This allows:

Retailers
Manufacturers
Distributors
E-commerce platforms
Logistics providers

to exchange product information efficiently and accurately.

Types of GS1 Barcodes

GS1 supports several barcode formats depending on industry needs and product requirements.

Common GS1 barcode formats include:

EAN/UPC barcodes
GS1-128 barcodes
DataMatrix codes
QR codes with GS1 Digital Link
ITF-14 barcodes

Different barcode formats are designed for:

Retail products
Logistics packaging
Healthcare products
Warehouse management
E-commerce systems

How GS1 Barcodes Work

GS1 barcodes contain structured product data encoded into scannable symbols.

The barcode typically includes:

Company prefix
Product identifier
Serial information
Batch numbers
Expiration dates

When scanned, the system instantly retrieves product data from inventory or retail databases.

This simplifies:

Checkout processes
Inventory tracking
Product authentication
Warehouse management
Logistics coordination

How to Get a GS1 Barcode

Many businesses search for how to get a gs1 barcode when launching products or entering retail distribution channels.

The process typically involves several steps.

Register With GS1

Businesses first need to register with their local GS1 organization.

Registration provides access to:

A GS1 company prefix
Unique product identifiers
Barcode generation standards
Global product registration systems

The company prefix becomes part of the product identification structure.

Obtain GTIN Numbers

After registration, businesses receive GTINs (Global Trade Item Numbers).

GTINs uniquely identify individual products and product variations.

Different product sizes, colors, or packaging formats usually require separate GTINs.

Generate the Barcode

Once GTINs are assigned, businesses can generate GS1-compliant barcodes using approved barcode software or platforms.

The barcode must follow GS1 formatting standards to ensure:

Accurate scanning
Retail compatibility
Global recognition

Add the Barcode to Packaging

After generation, the barcode is added to:

Product packaging
Labels
Shipping cartons
Product documentation

Proper placement and sizing are essential for scan reliability.

Test the Barcode

Before mass distribution, businesses should verify:

Scan quality
Print accuracy
POS compatibility
Retail system recognition

Poor barcode quality can create supply chain and checkout issues.

How to Use GS1 Barcode

Businesses often ask how to use gs1 barcode systems effectively across retail, logistics, and inventory operations.

GS1 barcodes support multiple operational functions.

Retail Checkout Systems

Retailers scan GS1 barcodes at checkout to:

Retrieve pricing information
Update inventory automatically
Simplify transactions
Improve checkout speed

This reduces manual entry errors significantly.

Inventory Management

Warehouses and retailers use GS1 barcodes for:
