You Have an IEC Code — So Why Does a Foreign Buyer Still Want a DUNS Number?
If you're already an IEC (Import Export Code) holder, you might assume you're fully set up for international trade — and for customs clearance and legal compliance, you are. But many Indian exporters discover, often mid-negotiation with a foreign buyer or platform, that having a GSTIN, IEC, or CIN isn't always considered sufficient on its own.
Here's why: your IEC code, GST number, and CIN are all valid only within India. A DUNS number is the one identifier in this list that's recognized and verifiable internationally — which is exactly what many foreign buyers are actually asking for when they request a "business verification number." This page explains exactly what each of these identifiers does, why they're not interchangeable, and how to get a DUNS number to complement your existing IEC registration.
A D-U-N-S Number is always free and is issued only by Dun & Bradstreet. Scalix Tech is an independent consulting service — we are not affiliated with, endorsed by, or authorized by D&B, or with DGFT. We never charge for "issuing" the number itself. What we offer is documentation guidance and application support, focused on getting your business details consistent across your IEC, GST, and DUNS records.

DUNS Number vs IEC vs GSTIN vs CIN — What's the Actual Difference?
Indian regulatory registries serve domestic clearance and tax compliance, while DUNS provides the standardized credentials required globally:
None of your Indian-issued identifiers give a foreign buyer an independent, internationally standardized way to verify your business exists, is legitimate, and is creditworthy. A DUNS number does exactly that — which is why it keeps coming up even after you've already completed your IEC registration.
When Exporters & IEC Holders Actually Need a DUNS Number
Bidding on Global Tenders
Many foreign government and multilateral tenders specifically ask for a DUNS number alongside your financial and compliance documentation.
International Marketplaces
Platforms and supplier directories serving global buyers often require a verified DUNS number as part of vendor onboarding verification.
Multinational Supplier Chains
Entering a supplier relationship with a multinational company — large global companies frequently rely on Dun & Bradstreet's verification before onboarding.
Foreign Buyer Due Diligence
International buyers increasingly prefer suppliers with a confirmed, verifiable identity, since it reduces risk on international financial transactions and shortens delays.
Global Business Credit Profile
Building a global business credit profile — highly useful for exporters planning to scale, seek trade financing, or work with multiple international partners over time.
If you're only trading domestically or your current buyers haven't asked for one, you may not need a DUNS number yet — but it's worth having ready before you start negotiating with new international partners, since requests for it often come up later in a deal than expected.
Documents Required for DUNS Number Registration as an Exporter / IEC Holder
IEC Certificate
Demonstrates your trading status and is commonly referenced as supporting evidence of your international trade activity.
Business Registration Certificate
Certificate of Incorporation, GST Certificate, or Udyam Registration, depending on your business structure.
PAN Card
Of the business entity.
Registered Office / Business Address Proof
Should match your IEC and GST records exactly.
Authorized Signatory Details
Name, designation, and a reachable phone/email for D&B's verification process.
Contact Information
Business phone number, email, and official website, since these will appear in your D&B business profile and are often what foreign buyers check first.
Financial Records
Larger exporters or those bidding on bigger international contracts may be asked to provide financial information to help D&B assess business stability.
The detail that matters most for exporters specifically: your business name and address need to match exactly across your IEC certificate, GST registration, and DUNS application. Since foreign buyers and international platforms may cross-check your DUNS profile against your IEC or company registration, even small inconsistencies can raise questions during their due diligence process.
How to Apply for a DUNS Number as an Exporter — Step by Step
Ensure the following structural steps are strictly completed to align your active registry profiles:
Check if your business already has a DUNS number. If you've worked with foreign buyers, banks, or international platforms before, D&B may already have a record. Search the official D&B database by your business name first.
Gather your IEC certificate and core business documents — PAN, GST certificate, and Certificate of Incorporation if applicable.
Confirm your registered address is current and matches your IEC and GST records exactly.
Apply on the official Dun & Bradstreet India website, selecting the entity type that matches your business structure.
Enter your business name and address exactly as they appear on your IEC certificate and GST registration.
List a reachable authorized signatory for D&B's verification process.
Be prepared to share basic financial information if you're a larger exporter or applying in connection with bigger international tenders.
Submit and track your application, responding promptly to any D&B follow-up requests.
How Long Does It Take?
Per Dun & Bradstreet's own published guidance, standard DUNS number registration can take up to 30 business days. Standard processing is free; D&B also offers its own optional paid expedited service for exporters needing a faster turnaround — particularly relevant if a foreign buyer or tender has a tight deadline. This is D&B's own paid tier, not something any third party controls.
IEC Context: Worth comparing to your IEC timeline for context: IEC registration through DGFT is typically completed within just a few working days once documents are submitted, since it's a different process entirely. It's worth applying for your DUNS number well before you expect a foreign buyer or international platform to ask for it, rather than scrambling once a deal is already in progress.

Common Mistakes Exporters Make With DUNS Applications
Avoid these structural missteps to ensure seamless verification clearance:
1. Indian Identifier Assumptions
Mistake: Assuming IEC, GST, or CIN is sufficient for international verification
None of these are recognized or independently verifiable outside India — a DUNS number is what actually closes this gap for foreign buyers.
2. Profile Inconsistencies
Mistake: Business name inconsistency between IEC certificate and DUNS application
Even tiny differences can raise questions and trigger delays during a foreign buyer's legal due diligence process.
3. Skipping Database Audits
Mistake: Applying without checking for an existing DUNS record first
Exporters who have worked with international clients before sometimes already have an active profile without realizing it.
4. Financial Preparedness
Mistake: Not having financial documentation ready when bidding on larger tenders
Some applications, especially for bigger exporters, require structured financial declarations to assess business stability.
5. Outdated Dynamic Profiles
Mistake: Treating the DUNS number as a one-time task rather than keeping the profile updated
If your business address, ownership, or financial details change, your D&B profile should be updated too — an outdated DUNS profile can seriously undermine credibility.

Frequently Asked Questions
Is a DUNS number required to get an IEC code?
No — IEC registration through DGFT runs on PAN, address proof, and bank details, with no DUNS requirement. A DUNS number is a separate, additional step that becomes relevant once you're dealing with foreign buyers, international tenders, or global platforms that ask for it specifically.
If I already have an IEC code, do I still need a DUNS number?
It depends on who you're trading with. Your IEC authorizes you to legally import/export from India, but it isn't recognized internationally. If a foreign buyer, international tender, or global marketplace asks you to verify your business identity, a DUNS number is typically what they're actually asking for.
Is the DUNS number free for exporters?
Yes. The standard D-U-N-S number application is completely free and issued directly by Dun & Bradstreet. Our fees, when you use our service, cover only documentation guidance and application support, never the number itself.
What’s the difference between a DUNS number and a CIN?
A CIN confirms your company is legally incorporated under Indian law, but it isn't valid or verifiable outside India. A DUNS number is recognized internationally and is what foreign buyers and institutions typically rely on instead.
Can a sole proprietor exporter with an IEC get a DUNS number?
Yes — DUNS number eligibility isn't limited to incorporated companies. Proprietorships, partnerships, and LLPs engaged in export can apply, generally using their IEC certificate alongside their other business documents as supporting evidence.
How long does it take to get a DUNS number after getting an IEC?
These are separate, unrelated timelines. IEC registration is typically completed within a few working days through DGFT. A DUNS number, applied for separately through Dun & Bradstreet, can take up to 30 business days for standard, free processing.
