Most Common Barcode Types Used in Retail and Warehousing

Barcodes are essential to modern business operations. Whether you're managing a retail store, a warehouse, or an eCommerce fulfillment center, barcodes play a critical role in tracking inventory, processing sales, and streamlining supply chains. But not all barcodes are created equal. There are many different barcode types, each suited for specific applications. Choosing the right one can greatly impact the efficiency of your operations.

At E.D. Systems Inc., we help businesses implement barcode and scanning systems that improve accuracy and workflow. In this guide, we’ll explore the most common barcode types used in retail and warehousing, explain what makes them different, and help you decide which is right for your needs.

Why Understanding Barcode Types Matters

Barcodes may seem simple, but they serve different purposes depending on the format and environment. Using the wrong barcode type can lead to scanning issues, inaccurate data, or compliance problems with partners or suppliers. That’s why understanding the core barcode types is key for businesses in:

  • Retail
  • Warehousing
  • Manufacturing
  • Logistics
  • Distribution
  • eCommerce

There are two main categories of barcodes:

  • 1D Barcodes (Linear) – A series of black and white lines that represent data.
  • 2D Barcodes (Matrix) – Encodes data both horizontally and vertically, allowing more information in a smaller space.

Let’s break down the most widely used barcode types across retail and warehousing operations.

1D Barcode Types Commonly Used in Retail and Warehousing

1. UPC (Universal Product Code)

Best for: Retail product labeling and point-of-sale scanning

The UPC barcode is one of the most recognizable and widely used barcodes in the world. You’ll find it on nearly every retail product sold in stores.

Key Characteristics:

  • 12 digits in total
  • Used to identify individual retail items
  • Scanned at checkout and used for inventory tracking
  • Easy to scan quickly with most barcode scanners

Why It's Popular: UPC barcodes are the industry standard for consumer goods in North America. They’re ideal for fast scanning at point-of-sale (POS) systems and integrate well with retail inventory systems.

2. EAN (European Article Number)

Best for: International retail and global supply chains

Similar to UPC but with broader global use, the EAN barcode is widely used in Europe and other countries for retail products.

Key Characteristics:

  • 13 digits (EAN-13) or 8 digits (EAN-8 for small packages
  • Compatible with global retail and distribution systems
  • Often used by manufacturers and wholesalers with international reach

Why It’s Important: If your business imports or exports goods internationally, EAN is the barcode type most commonly required by partners and distributors outside the U.S.

3. Code 128

Best for: Warehousing, shipping labels, and product tracking

Code 128 is a high-density barcode used extensively in logistics, distribution, and warehouse management.

Key Characteristics:

  • Supports full ASCII characters (numbers, letters, and symbols)
  • Compact and capable of encoding large amounts of data
  • Commonly used on shipping labels and pallet tags
  • Scanned by most 1D barcode readers

Why It’s Ideal for Warehousing: Code 128 is versatile and efficient, often used for serialized inventory, pallet IDs, and shipping tracking. Its compact format makes it easy to fit onto smaller labels.

4. ITF (Interleaved 2 of 5)

Best for: Carton labeling and bulk shipping

ITF barcodes are used to label cases, cartons, and other bulk packaging. They are readable by industrial barcode scanners even when printed directly on cardboard.

Key Characteristics:

  • Encodes only numeric data
  • Wide and tall bars for high visibility
  • Excellent for low-resolution printing
  • Designed for scanning in tough warehouse environments

Why It’s Useful: Ideal for scanning large packages on conveyor belts, ITF barcodes help maintain efficiency during bulk processing and logistics operations.

2D Barcode Types Gaining Popularity in Modern Supply Chains

While 1D barcodes remain the industry standard, 2D barcodes are becoming increasingly common due to their ability to store more data in a smaller space.

1. QR Code (Quick Response Code)

Best for: Marketing, mobile payments, and in-store engagement

Originally developed for the automotive industry, QR codes are now everywhere—from product packaging to payment systems to inventory labels.

Key Characteristics:

  • Square-shaped pattern of black and white modules
  • Can encode website URLs, contact info, text, or numbers
  • Scannable by smartphones and 2D barcode scanners
  • Error correction capabilities for damaged codes

Why It’s Effective: QR codes are incredibly versatile and easy to use. In warehousing, they’re often used for asset tagging and maintenance tracking. In retail, they support customer engagement and loyalty programs.

2. Data Matrix

Best for: Small items, electronics, and medical packaging

Data Matrix codes are compact 2D barcodes commonly used where space is limited. They’re especially useful in industries that require high traceability, like pharmaceuticals and electronics.

Key Characteristics:

  • Stores large amounts of data in a small area
  • Works well on curved or irregular surfaces
  • Strong error correction for high-reliability scanning
  • Often used to meet regulatory requirements in manufacturing

Why It’s Gaining Ground: With regulatory compliance on the rise in many industries, Data Matrix barcodes are used to ensure traceability and product authentication.

3. PDF417

Best for: Shipping labels, government IDs, and transportation

PDF417 is a stacked linear barcode that combines some 1D and 2D features. It’s commonly used in logistics, including USPS shipping labels and driver's licenses.

Key Characteristics:

  • High data capacity (over 1,000 characters)
  • Encodes text, numbers, and images
  • Durable and scannable under challenging conditions
  • Often used for licensing, compliance, and documentation

Why It’s Practical: PDF417’s ability to store large datasets makes it a valuable tool for applications requiring detailed information on a compact label.

Choosing the Right Barcode Type for Your Operation

The type of barcode your business should use depends on several factors:

  • Industry requirements: Retailers often default to UPC or EAN, while warehouses prefer Code 128 or ITF for internal tracking.
  • Data volume: Need to store more than just a number? A 2D barcode like Data Matrix or PDF417 might be better.
  • Label size: Small products need compact barcode formats like Data Matrix or QR codes.
  • Scanning equipment: Make sure your scanners are compatible with the barcode type you choose. Many modern scanners read both 1D and 2D codes.
  • Compliance standards: Some industries require specific barcode types for traceability, safety, or regulatory compliance.

If you’re unsure, working with a barcode solutions provider can help ensure the right setup for your business.

Why Barcode Type Matters for Efficiency and Accuracy

Choosing the right barcode type isn’t just about compliance or aesthetics—it has real business implications:

  • Speeds up checkouts and inventory scans
  • Reduces data entry errors
  • Improves order accuracy
  • Streamlines warehousing operations
  • Enhances supply chain visibility

When barcodes are selected and implemented correctly, businesses see improved productivity, smoother workflows, and fewer disruptions.
