Retail barcodes are entering a major period of change. Traditional UPC and EAN barcodes have supported product identification for decades, but businesses increasingly need to carry more information than a standard 1D barcode can hold.

GS1’s 2027 initiative is designed to expand retail point-of-sale systems so they can read approved 2D barcodes alongside traditional linear barcodes. Importantly, 2027 is a readiness goal for retail scanning capability, not a date when every existing UPC barcode suddenly becomes unusable.

What Is Changing With 2D Barcodes?

Traditional retail barcodes mainly provide a product identifier such as a GTIN. When the barcode is scanned, the retailer’s system uses that number to locate information such as product name and price.

A 2D barcode can carry considerably more structured information in a smaller space.

Depending on the chosen GS1 solution and business use case, it may support information such as lot numbers, expiration dates, serial numbers, or links to additional digital product information.

This gives businesses an opportunity to use a barcode for more than basic checkout identification.

Why Is Retail Moving Toward 2D Barcodes?

Modern retail operations require more detailed product information. Businesses are working to improve traceability, inventory visibility, recalls, expiration management, consumer information, and supply chain efficiency. Traditional linear barcodes were not designed to handle all of these requirements directly.

2D barcodes provide greater data capacity and can support both operational and consumer-facing applications.

For example, product data connected through a 2D barcode may help a business provide information about ingredients, recycling, product instructions, or other digital resources while still supporting product identification.

What Does the 2027 Goal Actually Mean?

One of the biggest misunderstandings is that every business must remove its existing UPC or EAN barcode in 2027.

That is not the goal. The industry objective is for retail point-of-sale systems to be capable of reading and processing defined GS1-compliant 2D barcodes by the end of 2027, in addition to existing linear barcodes. GS1 also expects the transition to happen gradually, with 1D and 2D symbols coexisting for some time.

Businesses therefore should think of 2027 as part of a transition rather than an overnight replacement.

Which 2D Barcode Might Be Used?

There is not one universal 2D barcode that will automatically replace every UPC.

Different applications may use different GS1-supported data carriers. Two important options include GS1 DataMatrix and QR Codes used with GS1 standards.

The right choice depends on the product, industry, information requirements, and where the barcode needs to be scanned.

For example, a business focused heavily on traceability may have different requirements from a consumer brand that wants to connect shoppers with online product information.

This is why businesses should begin by defining their use case rather than choosing a barcode simply because it is newer.

Retailers Should Review Their Scanning Systems

Retailers need to determine whether their existing point-of-sale equipment can read 2D symbols.

Many modern imaging scanners already have 2D capabilities, but hardware is only one part of the process. Software must also be able to interpret the information correctly and send the required data to the appropriate business systems.

Testing should therefore include the complete process.

A scanner successfully recognizing a QR Code or DataMatrix symbol does not automatically mean the point-of-sale system is prepared to process all of the information carried within it.

Brand Owners Should Review Packaging Early

Manufacturers and brand owners should avoid waiting until a packaging redesign is already complete before considering 2D barcode requirements.

Barcode size, location, available packaging space, print quality, and the possibility of temporarily carrying both 1D and 2D symbols can affect the overall layout. Early planning allows the packaging team to reserve appropriate space and test symbols on the actual product.

This is especially valuable for small packages where available label space is limited.

Data Quality Will Become Even More Important

The ability to encode more information also creates greater responsibility for keeping that information accurate.

If expiration dates, batch details, serial numbers, or digital product information are associated with a barcode, businesses need reliable processes for generating and maintaining that data.

A more capable barcode cannot fix incorrect source information.

The transition should therefore include both barcode preparation and improvements to the systems that manage product data.

Start With a Practical Transition Plan

Businesses do not need to change every product at once. A practical approach is to review current barcode systems, identify priority use cases, check scanner capabilities, assess packaging space, and test 2D solutions on selected products.

The 2027 transition is ultimately about giving retail systems the ability to work with more capable barcodes. Businesses that begin testing and planning early can make the change gradually instead of treating it as a last-minute packaging or technology project.

A barcode can be created with the correct number, proper dimensions, and good print contrast but still cause scanning problems if it is placed in the wrong part of the package.

Barcode placement is an important part of GS1 compliance because scanners need clear and predictable access to the symbol. Poor positioning can cause the barcode to bend, wrinkle, become covered, or sit too close to an edge. These issues can reduce scanning reliability even when the barcode itself is technically correct.

For businesses preparing product packaging, placement should therefore be considered during the design stage rather than after the artwork is complete.

Why Barcode Placement Matters

Barcode scanners work best when they can clearly capture the entire symbol.

If a barcode is placed around a corner, over a fold, beneath a flap, or close to an uneven surface, part of the symbol may become difficult for the scanner to read.

Consistent placement also makes scanning faster.

In retail environments, employees often handle hundreds of products during a shift. When barcodes appear in predictable areas, operators can find and scan them more efficiently.

Automated systems depend even more heavily on consistent placement because products must pass through a scanner's field of view without someone manually adjusting the package.

Use Flat and Accessible Areas Whenever Possible

A barcode should generally be positioned on a surface where it can remain flat and visible.

Packaging features such as seams, folds, perforations, sealing areas, and raised edges should be avoided when possible. If a barcode is printed across a package seam, the bars may become distorted when the package is closed. Similarly, a label placed over a rough or uneven surface may wrinkle or lift.

The packaging design should provide enough uninterrupted space for the complete barcode, including the surrounding clear areas required for reliable scanning.

Keep Barcodes Away From Package Edges

Placing a barcode extremely close to the edge of packaging can create several problems. The symbol may be damaged during handling, partly covered by packaging folds, or difficult for a scanner to capture completely.

GS1 placement guidance generally favors positioning barcodes within a predictable area while maintaining sufficient distance from package edges.

For many traditional retail packages, the lower-right area of the back is commonly preferred when the package design allows it.

However, the exact position can vary depending on the packaging type and how the product will be handled.

Avoid Curves That Distort the Barcode

Cylindrical and curved products require additional planning. A barcode placed incorrectly on a bottle, jar, or tube can wrap too far around the surface. This makes it difficult for a scanner to see the complete width of the symbol at one time.

The direction of the bars can make a major difference.

For narrow cylindrical products, barcode orientation may need to be adjusted so the curvature does not distort the symbol excessively.

This is one reason packaging shape should be considered before finalizing barcode artwork.

Bags and Flexible Packaging Need Special Attention

Flexible packages can change shape after they are filled. A barcode that looks perfectly flat on an empty bag may become stretched, folded, or curved once the contents settle.

For this reason, barcode placement on bags should consider how the finished package will actually look during storage and scanning. The symbol should be positioned where the material is likely to remain as flat as possible and away from areas that commonly wrinkle or bulge.

Testing the filled package rather than only reviewing the digital design can help identify these issues early.

Do Not Let Other Design Elements Interfere

Packaging artwork should not interfere with the barcode's usable area. Text, borders, graphics, seals, stickers, or promotional labels placed too close to the barcode may reduce the clear space around it.

The barcode also should not be covered later by price stickers, security labels, or other operational markings.

A packaging team may create a technically correct barcode and then accidentally compromise it during the final design stage by adding another element too close to the symbol.

Barcode placement should therefore be reviewed as part of the complete packaging layout.

Consider How the Product Will Be Scanned

The best barcode position depends partly on where and how scanning takes place.

A consumer product scanned at a retail checkout has different requirements from a shipping case moving through a distribution center.

Large or heavy products may require barcode locations that employees can reach without lifting or turning the item excessively.

Logistics units may also need labels positioned so automated equipment can detect them while they move through warehouse systems.

Understanding the real scanning environment makes placement decisions more practical.

Review Placement Before Packaging Goes Into Production

Placement problems are much easier to fix during artwork development than after thousands of packages have been printed.

Businesses should review the barcode on the actual package format, not just on a flat computer screen. Factors such as folds, curves, seams, package filling, handling, and scanning direction can all affect the final result.

Correct barcode positioning supports both GS1 compliance and everyday operational efficiency.

A barcode should not simply be present somewhere on the package. It should be positioned where scanners can find it easily, capture it completely, and read it consistently throughout retail and distribution processes.

Achieving GS1 compliance is a critical milestone for businesses entering retail, healthcare, food, and logistics supply chains but it’s not always a smooth process. Many companies encounter common pitfalls that lead to rejected shipments, chargebacks, or delays. Understanding these typical compliance violations—and knowing how to fix them early can save time, reduce costs, and protect your reputation.

The Risk of Overlooking the Details

Non-compliance often stems from seemingly small oversights. Misassigned GTINs, incorrect barcode symbology, poor print quality, or missing data fields may go unnoticed internally but cause problems for retailers, distributors, or regulators downstream.

Addressing these details proactively ensures your labeling system not only works in theory but performs reliably in real-world supply chains.

Misassigned or Duplicated GTINs

One of the most common GS1 compliance violations is the incorrect assignment or duplication of GTINs. Each product variation must have its own unique identifier; reusing or improperly modifying GTINs for different items undermines inventory accuracy and traceability.

Fixing this problem requires businesses to maintain a centralized, carefully managed database of GTIN assignments—and to audit that database regularly as product lines expand.

Improper Barcode Symbol Selection

Different applications require different barcode types. Using UPC-A or EAN-13 where GS1-128 or ITF-14 is needed can cause scanning failures and system incompatibilities, particularly for cartons, pallets, or regulated goods.

To avoid this issue, businesses should align barcode selection with GS1’s recommended symbol types for their industry and packaging level.

Print Quality and Sizing Errors

Even a properly assigned GTIN and correct barcode symbol will fail if printed poorly. Common mistakes include inadequate contrast, distorted sizing, missing quiet zones, or improper placement.

Verifying print quality early using GS1’s verification tools—and working with experienced label providers helps ensure barcodes meet scannability standards before products reach the supply chain.

Missing Variable Data for Regulated Products

For industries like food and healthcare, variable data such as lot numbers, expiration dates, and batch codes are essential for traceability. Omitting this information or failing to encode it correctly into barcodes is a frequent cause of compliance failure.

Businesses can resolve this by implementing systems that automate the inclusion of variable data at the time of printing, reducing reliance on manual input and ensuring accuracy.

Why Early Action Pays Off

The costs of non-compliance are often hidden until they surface as rejected shipments, chargebacks, or customer complaints. Proactively identifying and addressing common violations ensures that your barcode system performs as intended from day one.

Build a Compliance-First Barcode Program

Common GS1 compliance mistakes don’t have to derail your business. By addressing misassigned GTINs, barcode symbol mismatches, poor print quality, and missing variable data early, businesses protect their reputation and streamline onboarding with major partners.

AccuGraphiX helps companies build compliance-ready barcode systems that avoid these pitfalls, reduce delays, and keep goods moving efficiently through retail, healthcare, and food supply chains. Taking a proactive, informed approach to GS1 compliance ensures your business is ready to meet the highest global standards—right from the start.

GS1 standards are designed as a global framework for product identification and labeling—but the way these standards are applied varies significantly across industries. Retail, healthcare, and food sectors each face unique operational realities, compliance requirements, and stakeholder expectations. Understanding these differences is essential for any business that operates in multiple sectors or plans to expand into new markets.

Core Principles, Different Applications

While the foundation of GS1 standards is the same everywhere—ensuring globally unique product identification and scannable, consistent barcodes—sector-specific rules tailor these principles to industry needs. For example, a grocery item, a pharmaceutical product, and a retail fashion item may all carry a GTIN, but the formatting, labeling, and additional data required will differ depending on their sector.

How GS1 Compliance Differs in Retail

In retail, GS1 compliance focuses primarily on ensuring that each product variant (size, color, packaging type) has a unique GTIN and that barcodes can be scanned quickly and reliably at checkout. UPC-A and EAN-13 symbols dominate this environment, where speed and compatibility with POS systems are key.

Retailers often require suppliers to submit product data to centralized databases and to follow strict label placement guidelines to ensure smooth scanning at the point of sale.

Unique Needs for Healthcare Labeling

Healthcare adds another layer of complexity. Regulatory requirements such as the FDA’s Unique Device Identification (UDI) rule in the United States mean that labels must contain more than just a GTIN—they may also include expiration dates, batch or lot numbers, and manufacturer information encoded in GS1-128 or DataMatrix formats.

Labels must also meet stringent durability standards, remaining scannable through sterilization, handling, and chemical exposure. For patient safety and regulatory traceability, healthcare GS1 compliance demands precision and reliability at every level.

Food Industry Traceability Requirements

In food production and distribution, traceability is paramount. GS1 standards help businesses track and trace every item from farm to fork. Labels often require not just product identifiers but additional data such as harvest dates, batch numbers, and country of origin.

Food products may also need labels designed to survive cold chain environments, moisture, and rough handling. Label durability and placement are crucial to ensure that traceability is maintained even when goods pass through complex supply chains.

The Role of Variable Data in Sector-Specific Compliance

Many sector-specific requirements involve variable data—such as expiration dates or lot numbers—that must be incorporated into barcode labels accurately and consistently. Customizing barcode systems to accommodate these requirements helps businesses maintain compliance without adding manual steps or risking errors.

Customization Is the Key to Multi-Sector Success

For companies working across retail, healthcare, and food industries, a one-size-fits-all barcode solution is inadequate. Tailoring barcode design, materials, and workflows for each sector ensures that labels perform reliably and meet compliance requirements everywhere they are used.

AccuGraphiX helps businesses build flexible, compliant barcode systems that adapt seamlessly to the demands of multiple sectors. By understanding how GS1 rules differ by industry, companies can design labeling strategies that keep operations running smoothly while protecting customer trust and meeting regulatory standards.

Labeling your products with barcodes may seem like a straightforward step, but when you're dealing with GS1 standards, the details matter. GS1 compliance ensures that your barcodes meet global formatting and identification standards—something required by most major retailers, distributors, and e-commerce platforms.

Whether you're new to barcoding or re-evaluating your current labeling system, following a GS1 compliance checklist can help you avoid delays, chargebacks, or rejected products.

1. Obtain a GS1 Company Prefix

The first step toward GS1 compliance is licensing a GS1 Company Prefix. This prefix links every product you label to your business and forms the base for creating Global Trade Item Numbers (GTINs).

Without a GS1-issued prefix, your barcodes may not be recognized by retail partners or supply chain systems.

2. Assign Unique GTINs to Each Product

Each product variation—size, color, package type—must have its own GTIN. This unique identifier allows for precise tracking, inventory control, and sales reporting.

Avoid reusing or modifying GTINs across different products. Consistency and uniqueness are key to compliance.

3. Use the Correct Barcode Symbol

Not all barcodes are created equal. GS1-compliant products often use the UPC-A or EAN-13 symbols for retail scanning. For shipping cartons or logistics units, GS1-128 or ITF-14 may be required.

Choosing the right barcode format ensures compatibility with your retail partners’ systems and scanning equipment.

4. Verify Proper Print Quality and Sizing

GS1 has strict guidelines for barcode size, placement, and print contrast. Poorly printed or incorrectly sized barcodes may be unreadable by scanners—even if the data is correct.

To ensure print quality:

Use high-resolution printing equipment
Follow GS1's minimum size and quiet zone recommendations
Test barcodes using barcode verification tools

5. Maintain Updated Product Data in the GS1 Database

Some marketplaces and retailers require your product information to be registered with GS1’s Global Data Synchronization Network (GDSN). This helps them verify ownership and ensure consistent data across platforms.

Make sure your product listings reflect the latest data, including:

GTIN assignments
Product dimensions and weights
Brand and packaging updates

6. Follow Label Placement Guidelines

Correct label placement helps ensure smooth scanning throughout the supply chain. GS1 recommends placing barcodes on flat, scannable surfaces—away from folds, seams, or edges.

Proper placement reduces scan errors at retail, warehouse, and logistics checkpoints.

7. Keep Compliance Documentation On Hand

Retailers or partners may request proof of compliance, such as your GS1 prefix license or barcode verification reports. Keeping this documentation organized helps streamline onboarding and audit processes.

Laying the Groundwork for Global Readiness

Following GS1 standards isn’t just about avoiding errors—it’s about setting up your business for long-term success. A compliant labeling system builds trust with retailers, ensures operational efficiency, and opens the door to new markets.

By using this checklist as your guide, you can ensure your barcodes meet global standards while supporting the smooth flow of products from shelf to shopper.

In a world where supply chains stretch across continents and retail platforms operate at global scale, credibility is everything. Whether you're launching a new product or expanding into new markets, GS1 compliance signals that your business meets internationally recognized standards—and that matters to your partners, distributors, and customers.

What GS1 Compliance Means for Your Brand

GS1 is the global authority on product identification standards, and compliance ensures that your barcodes meet expectations for format, traceability, and accuracy. When your products follow GS1 standards, each barcode carries essential data—like brand ownership, product type, and packaging level—in a globally accepted structure.

Retailers and distributors see GS1-compliant barcodes as a sign that your business is professional, prepared, and capable of scaling responsibly. It shows that your internal systems are compatible with the larger retail and logistics ecosystem.

Why Retailers Prioritize GS1-Registered Products

Major retailers use automated systems to track inventory, validate shipments, and process sales. If your product barcodes aren't GS1-registered, they may not scan properly, appear in databases, or match expected product listings.

By using GS1-compliant barcodes, you:

• Avoid listing and fulfillment issues on platforms like Amazon or Walmart
  
• Improve onboarding speed with retailers or distribution partners
  
• Reduce the chance of shipment rejections or delays
  
  

Compliance becomes a gateway to more shelf space, better platform placement, and wider visibility.

Trust and Traceability Go Hand in Hand

In regulated industries such as food, healthcare, and cosmetics, traceability isn’t just a feature—it’s a requirement. GS1 standards allow every stakeholder in the supply chain to track products from manufacturing to final sale.

This transparency builds trust by enabling:

• Efficient recalls and quality assurance checks
  
• Verification of expiration dates and lot numbers
  
• Protection against counterfeiting or mislabeling
  
  

Suppliers, retailers, and end customers all benefit from the confidence that GS1-compliant labeling provides.

Supporting International Growth

As your brand expands beyond domestic markets, GS1 compliance becomes even more critical. International supply chains depend on consistent product identifiers to avoid confusion across languages, currencies, and logistics systems.

GS1 barcodes help:

• Standardize product data for cross-border shipping
  
• Align with customs documentation and import/export controls
  
• Facilitate localization without compromising accuracy

Compliance ensures that your product is recognized and accepted by partners around the world.

Positioning Your Business as Retail-Ready

When a business invests in GS1 compliance, it demonstrates readiness to work with large-scale retailers and distributors. It shows attention to detail, commitment to accuracy, and alignment with industry best practices.

For growing businesses, GS1 compliance is not just a technical requirement—it’s a credibility asset. It signals to everyone in the supply chain that your operation is built for reliability and long-term success.
