As an online seller, you need accurate barcodes for your products to list on Amazon and other marketplaces. But what happens when you’re unsure how to create barcode for your product? The confusion over whether to use tools like the Amazon barcode generator often leads to listing rejections and tracking issues. In this blog, we’ll guide you on how to create barcode for product successfully. We'll also explain why using legitimate, globally accepted identifiers is critical to avoiding listing and operational errors.

EAN/GTIN Importance

Why You Need a Barcode, Business & Marketplace Reality

A barcode is a unique product identifier recognised globally. It’s essential for selling both offline and online, especially on platforms like Amazon.
Most e-commerce platforms, including Amazon, require barcodes for:

  • Listing products
  • Managing inventory
  • Enabling scanning at fulfilment centres


Without a valid barcode, your product may face:

  • Rejected listings
  • Scanning failures at retail points of sale
  • Inventory discrepancies
  • Issues with global markets and export compliance


The Amazon barcode generator or a product barcode generator is useful, but they must be linked to authentic identifiers like GTINs (Global Trade Item Numbers). Only a valid barcode will ensure your products are accepted globally, maintaining trust and compliance.

What Happens If You Try to Buy Barcodes Online from Random Sources?

Many small businesses try to buy barcodes online from third-party sellers, assuming it's a cheap shortcut. However, this can cause a range of issues:

  • Duplicate barcodes - Randomly generated barcodes may conflict with other products.
  • Marketplace rejection - Many platforms use central registries, and invalid codes won’t pass validation.
  • Inventory errors - Using unverified barcodes leads to mismatches in stock and delays.
  • Listing suppression - Invalid codes lead to listings being hidden or rejected.


Choosing a product barcode generator that’s not authorised can be a false economy. Although you save money upfront, the legal and operational issues you face later are far more costly.

The Only Legitimate Way to Get Your Barcode in India

The only way to get valid, globally accepted barcodes is to register through an authorised source. In India, GS1 India is the recognised body that allocates GTINs with the “890” prefix for Indian products.

Steps to Register Your Barcode:

  • Visit the official registration portal - Go to the GS1 India "Register for Barcodes" page.
  • Submit business details - Provide documents like PAN, GST (if applicable), and business proof.
  • Choose your barcode plan - Based on the number of products or company needs (e.g., for many SKUs or individual codes).
  • Pay the registration fee - Based on your chosen plan.
  • Receive GTINs and access tools - Once verified, you get your GTINs with an “890” prefix.
  • Generate barcodes - Create barcode images in the required format (EAN, UPC, etc.) and use them for listings, packaging, and inventory management.


Having your barcode issued through GS1 India ensures your products are globally recognised and compliant with marketplaces, retailers, and export regulations.

 

Which Barcode Type Do You Need?

Selecting the right barcode type is crucial for correct product representation:

  • 1D Barcodes (EAN/UPC) - Ideal for retail consumer products and POS scanning.
  • Logistics Codes (GS1-128, ITF-14) - Used for shipping cartons and pallets.
  • 2D Barcodes (QR, DataMatrix) - Best for traceability, batch data, and product info.


GS1 India offers guidance on choosing the right barcode type during registration. Incorrect barcode types may affect scanning at retail points or lead to compliance issues.

 

How Valid Barcodes Support Marketplaces & Retail Channels

GS1 India’s barcodes are not only accepted by Amazon but by all major e-commerce and retail platforms. They ensure smooth product listings and compliance.
Benefits of using valid barcodes include:

  • Faster product listing approval
  • Accurate POS scanning

Tips Before You Register

Before registering for your barcode, ensure you're ready by following this checklist:

  • Confirm your business registration documents (PAN, GST, turnover).
  • Estimate how many SKUs you need barcodes for.
  • Understand whether you need a company prefix or individual codes.
  • Prepare your product data (descriptions, variants, packaging).
  • Know your primary selling channels (retail, e-commerce, export).

Conclusion

Creating a barcode for your product isn’t just a technical task; it’s a strategic decision. Without a legitimate barcode, you risk rejection and delays in retail and online sales. Using tools like the Amazon barcode generator can help you create barcode images, but these must be linked to a globally valid product identifier. By registering through GS1 India, you ensure compliance and avoid future complications. Follow the registration steps and generate accurate, universally accepted barcodes for seamless product listings, better compliance, and smoother supply chain operations.
