If you’re selling online from India whether through a marketplace, your own website, or across borders you’ve likely come across “DUNS number” somewhere in a seller setup flow or a compliance checklist, without a clear sense of whether it actually applies to you. The honest answer: it depends entirely on which platforms you sell on and how your business is structured, not on the fact that you’re an e-commerce seller in general. There’s no single rule that says “online sellers need a DUNS number” it comes down to specific marketplace and account requirements.
Why This Question Comes Up So Often for E-commerce Sellers
E-commerce sellers tend to encounter DUNS numbers more than other types of businesses simply because so many major platforms, marketplaces, payment processors, and B2B wholesale systems lean on D&B’s verification system to confirm sellers are legitimate businesses, not anonymous individuals. If you sell across multiple platforms, you may run into this requirement on one and not another, which is where a lot of the confusion comes from.
Where It Actually Comes Up for Indian E-commerce Sellers
Amazon: The requirement here isn’t uniform; it depends heavily on which specific Amazon program or account type you’re setting up. Standard Seller Central accounts generally don’t require one, while specific programs like Amazon Global Selling or certain Amazon Business B2B setups sometimes do. We’ve covered this in detail across a few dedicated guides: Amazon Seller Central DUNS Number Requirement, Is a DUNS Number Optional for Amazon Business?, and Amazon Small Business Badge DUNS Number.
Flipkart and other Indian marketplaces: Domestic Indian marketplaces typically rely on GST and standard business registration for seller verification, rather than DUNS-based checks, since they’re primarily serving the domestic market. A DUNS number generally isn’t part of standard seller onboarding here.
Your own website or D2C store: If you’re selling through your own e-commerce site, there’s no inherent DUNS requirement — this only becomes relevant if you’re using a specific payment gateway, platform integration, or B2B wholesale system that happens to require business verification through D&B.
Cross-border and international marketplaces: If you’re expanding into selling on platforms based outside India — certain US, UK, or EU marketplaces, or B2B wholesale platforms serving international buyers — DUNS-based verification is more commonly requested, since it’s a standardized way for a foreign platform to confirm your business’s legitimacy without navigating India’s specific registration system.
App or software-based selling: If your e-commerce business also involves publishing a shopping app, you may separately encounter DUNS requirements tied to organization accounts on platforms like Google Play Console or Apple Developer, which is a different trigger entirely from your marketplace selling activity.
What This Means in Practice
Rather than assuming you need a DUNS number because you’re an e-commerce seller, check the specific onboarding requirements of whatever platform or program you’re actually setting up. If DUNS isn’t mentioned in your specific account setup flow, it’s not required for what you’re doing right now.
When It’s Worth Getting One Proactively
If you’re planning to expand beyond domestic selling — into Amazon Global Selling, international B2B wholesale, or cross-border marketplaces — getting a DUNS number ahead of time can save you a scramble later. Since it’s free and doesn’t expire, there’s no real cost to applying early if international expansion is genuinely part of your roadmap.
If you’re purely focused on domestic platforms like Flipkart or Indian marketplaces with no near-term international plans, there’s no urgency to get one just because the term keeps showing up in general e-commerce guides.
Common Mistakes E-commerce Sellers Make
Assuming every platform treats DUNS the same way: As shown above, requirements vary significantly even within the same company Amazon’s standard Seller Central and Amazon Global Selling have different expectations entirely.
Using a brand name instead of your legal business name: E-commerce sellers frequently operate under a storefront or brand name that differs from their registered legal business name. If you do need a DUNS number, use your exact legal name matching your GST or incorporation documents not your store’s public branding.
Applying for a DUNS number “just in case” without checking first: Since standard DUNS applications are free and this doesn’t hurt, it’s not a major mistake, but it’s worth first checking D&B’s lookup tool in case your business already has one assigned automatically.
How to Apply If You Do Need One
- Check if you already have a DUNS number: using D&B’s official free lookup tool
- Apply directly through D&B’s official website: using your exact legal business name and registered address
- Provide your GST number, PAN, or CIN: wherever the application asks for a tax or registration identifier
- Submit and wait for verification: typically up to 30 business days for standard processing
