ई-कॉमर्स और मार्केटप्लेस विक्रेताओं के लिए GS1 मानक
Why Amazon, Walmart, and eBay require GTINs, how to list products with GS1 barcodes, and GTIN exemption policies for private-label sellers.
GS1 Standards for E-Commerce & Marketplace Sellers
Online marketplaces increasingly require GTINs for product listings. Amazon, Walmart, eBay, and Google Shopping all use GS1 barcodes as the foundation for product identification, search, and catalog integrity.
Why Marketplaces Require GTINs
GTINs solve the catalog matching problem. Without a standard product identifier:
- Thousands of sellers list the same product with different titles and descriptions
- Shoppers see duplicate listings with inconsistent information
- Price comparison becomes unreliable
- Returns and refunds are harder to process
With GTINs, the marketplace maps all listings for the same product to a single catalog entry, creating a cleaner shopping experience.
Platform-Specific Requirements
Amazon
- GTINs (UPC/EAN) required for most categories
- Brand Registry requires GS1-issued GTINs
- GTIN exemption available for private-label and handmade products
- Amazon verifies GTINs against the GS1 database
Walmart Marketplace
- GTINs required for all listings
- Must be GS1-registered (Walmart verifies against GS1 database)
- No GTIN exemption for standard product categories
eBay
- GTINs required for most categories
- Listings with GTINs receive higher search visibility
- Catalog matching uses GTIN as primary key
Google Shopping
- GTINs required for all products with a GTIN assigned by the manufacturer
- Products without GTINs receive lower ranking
- Google verifies GTIN authenticity
Getting GTINs for E-Commerce
The legitimate process:
- Join GS1 through your local Member Organization
- Receive a GS1 Company Prefix
- Assign GTINs to each product variation
- Enter GTINs in marketplace listings
Avoid: Purchasing individual UPC codes from third-party resellers. These codes may work initially but can be deactivated by GS1 or flagged by marketplaces during verification.
GTIN Exemptions
Some products do not require GTINs:
- Handmade and craft items: One-of-a-kind products
- Vintage and pre-owned: Products manufactured before barcode adoption
- Custom/made-to-order: Unique configurations
- Unbranded generic items: Commodities without manufacturer branding
To apply for an exemption on Amazon, submit a GTIN Exemption request through Seller Central with your brand name and product category.
Enhanced Content with GDSN
Sellers can use GDSN to push rich product data directly to marketplace catalogs:
- Standardized product descriptions and attributes
- High-resolution images
- Nutritional and safety information
- Package dimensions and weights
This eliminates manual data entry and ensures consistency across all marketplaces.
Best Practices
- Register with GS1 before listing on any marketplace (avoids future compliance issues)
- Use the same GTIN across all platforms (do not assign different codes per marketplace)
- Keep GS1 membership active (lapsed memberships cause listing suspensions)
- Update product data when packaging or formulations change
- Monitor marketplace notifications for GTIN-related compliance warnings
