Frequently Asked Questions
Everything you need to know about barcode generator for amazon sellers
What barcode does Amazon India require?
Amazon India accepts EAN-13, UPC-A, and ISBN barcodes. EAN-13 is the most commonly used format by Indian sellers. The barcode number should ideally be GS1-registered for brand-registered products to prevent catalog conflicts.
Do I need a GS1 barcode for Amazon?
For brand-registered products, Amazon requires GS1-registered barcodes. For private label products with a GTIN exemption approved via Amazon Brand Registry, you can sometimes use Amazon's internal ASIN system. Check Amazon Seller Central for your specific category's requirements.
What is FNSKU and how is it different from EAN?
FNSKU (Fulfillment Network SKU) is Amazon's internal barcode for products stored in its FBA warehouses. EAN-13 is your product's global product identifier used for the listing. FBA sellers typically need both: EAN for creating the listing, FNSKU on the physical product label sent to Amazon's warehouse.
Can I create a product label with my barcode for Amazon?
Yes. After generating your barcode here, click 'Create Product Label' to open Labeliy's label maker. You can design a complete product label with your brand name, product details, MRP, and barcode — all print-ready.
Can I put the same barcode on all units of the same product?
Yes — all units of the same product variant should carry the same barcode. Different variants (size, color, flavor) each need their own unique barcode number. Mixing barcodes between variants causes Amazon warehouse errors and customer complaints.
Which barcode format should I use for Amazon US vs Amazon India?
For Amazon India, use EAN-13. For Amazon US (Amazon.com), use UPC-A or EAN-13 — both are accepted. If you sell on both, EAN-13 works across all Amazon marketplaces globally, making it the single best format to standardize on.
Who Is This For
If you sell on Amazon India, every listing needs a valid product identifier like EAN or UPC, and every FBA unit needs a scannable label. This page is focused on Amazon sellers who want to quickly generate barcodes that match their catalog and pack them correctly for FBA and Easy Ship orders.
Private-label and brand-registered sellers who manage multiple ASINs benefit most from having a consistent barcode system. Without proper barcodes, Amazon may merge your listing with a similar product from another seller, hijack your Buy Box, or reject your FBA inbound shipment. A GS1-registered EAN-13 is the cleanest solution — it uniquely links your barcode to your brand in Amazon's and GS1's global database.
Once you have your barcode, use Labeliy's label maker to design complete product labels with your brand logo, product name, MRP, net quantity, and barcode — all on one print-ready sheet. This saves you from designing labels in a separate tool and ensures your barcode is correctly sized and positioned on the label.
Why You Need Barcodes
- Amazon requires a valid GTIN (EAN/UPC/ISBN) for most categories, and listing creation is much smoother when barcodes are ready.
- Proper barcodes on each unit prevent inventory mix-ups inside Amazon warehouses and reduce the risk of returns and account penalties.
- Having your own barcode system makes it easier to expand from Amazon to other channels like Flipkart, your own website, and offline retail.
- A GS1-registered barcode protects your product identity — preventing competitors from listing on your page or mixing their stock with yours.
Step by Step
- 1Check whether your ASINs use EAN-13, UPC-A, or ISBN and decide which barcode format you need for each product.
- 2Enter the exact product code you plan to submit in Seller Central and generate a clean, high-contrast barcode.
- 3Test-scan the barcode with a mobile app and confirm the number matches your listing details before printing labels.
- 4Print and apply the barcode stickers on each unit in a flat, visible area that Amazon scanners can reach during inbound processing.
Pro Tip
Keep a master sheet mapping ASIN → EAN/UPC → FNSKU so when Amazon raises a catalog or authenticity query, you can reply with precise code references in minutes rather than hunting through multiple systems.
