What Is a DUNS Number? Everything Indian Businesses Need to Know in 2026

If you’re an Indian business owner hearing “DUNS number” for the first time usually because a platform, supplier, or partner has just asked you for one this guide covers everything you actually need to know: what it is, who really needs one, how the process works from India specifically, and a few things that have changed recently that a lot of older guides online still get wrong.

What Is a DUNS Number?

A DUNS number (Data Universal Numbering System) is a unique nine-digit identifier assigned to a business by Dun & Bradstreet (D&B), a private business data company. It’s used globally to identify and verify businesses confirming that a company is real, legally registered, and accurately represented across the records platforms and partners rely on. D&B’s system now covers business records for hundreds of millions of businesses worldwide, making it one of the most widely recognized business identification standards internationally.

Think of it less as a government ID and more as a globally recognized “business fingerprint” , a stable reference point that different platforms and institutions can check against to confirm your business’s identity and basic details.

Who Actually Issues It, and Why It’s Free

D&B issues DUNS numbers directly, and standard registration has no cost. D&B’s revenue comes from separate paid products, business credit reports, data monitoring, and analytics services, not from charging businesses to be issued a DUNS number in the first place. Issuing numbers for free is actually how D&B keeps its global database as complete and useful as possible, since a paywall at the identification stage would work against the purpose of the whole system.

What a DUNS Number Is Not

This is worth being clear on, since a lot of confusion comes from mixing this up:

• It’s not a tax identification number: Your GST number, PAN, or CIN in India (or an EIN in the US) are separate identifiers issued by tax authorities, unrelated to D&B.
• It’s not a business registration or license: Registering your company with the MCA, getting GST registration, or obtaining any other government license is entirely separate from getting a DUNS number.
• It’s not required to legally operate a business in India; You only need one if something specific a platform, supplier, or contract asks for it.

Who Actually Needs a DUNS Number

You typically need a DUNS number if you’re doing one of the following:

• Applying for a global developer or business platform account: Apple Developer, Google Play Console (organization accounts), Microsoft Partner Center, or similar platforms that verify business legitimacy through D&B
• Completing business verification for Meta/Facebook advertising or commerce features: where a DUNS number is one of several accepted verification methods
• Working with international suppliers or B2B partners: who check business credibility through D&B’s database before extending trade credit or entering contracts
• Expanding into cross-border e-commerce: such as certain Amazon Global Selling programs
• Establishing credibility with international clients or investors: where a recognized global identifier can support your business’s legitimacy

If none of these currently apply to you, there’s no urgency to get a DUNS number just because you’ve heard the term doesn’t add anything to your day-to-day domestic operations on its own.

An Important Update: DUNS and US Government Contracting

Here’s something worth correcting clearly, since a lot of older content online still gets this wrong: as of April 2022, the US federal government no longer uses DUNS numbers for federal contracting or grants. The DUNS number was replaced by the Unique Entity ID (UEI), a 12-character identifier generated directly within SAM.gov, the US government’s own procurement system. If you’re pursuing US federal contracts or grants specifically, you now need a UEI through SAM.gov, not a DUNS number though DUNS numbers remain in use for the many other purposes covered above.

This is a genuinely important distinction, since it means DUNS numbers today are primarily relevant for commercial platform verification and B2B credibility, rather than direct US government procurement.

How the DUNS Number Application Process Works for Indian Businesses

1. Check if you already have one: Many Indian businesses already have a DUNS number without realizing it, since D&B sometimes assigns one automatically based on existing supplier or credit records. Use D&B’s official free lookup tool before applying.
2. Apply directly through D&B’s official website for India: The standard process is entirely online and free.
3. Provide your legal business name, registered address, business structure, and contact details: matching your GST registration, MCA filing, or other official documents exactly.
4. Provide your GST number, PAN, or CIN: wherever the application asks for a tax or registration identifier Indian applicants don’t need a US EIN.
5. Submit and wait for verification: which typically takes up to 30 business days for standard, free processing, though many businesses with clean, consistent registration details are verified sooner.
6. Receive your DUNS number by email: once approved.

What Slows Down or Complicates Applications

The vast majority of delays and denials come down to a small set of avoidable issues:

• Name mismatches: using a trade name or abbreviated version instead of your exact legal business name
• Address inconsistencies: a different address than what’s registered with GST or MCA
• Applying before registration is finalized: GST or company registration still pending
• Duplicate applications: not checking whether a DUNS number already exists before applying again
• Limited public record for very new businesses: which can push an otherwise legitimate application into manual review

Is There a “DUNS Number for India” Different From Other Countries?

No. The process is globally consistent Indian businesses use the same D&B registration system as businesses anywhere else, just with locally relevant identifiers (GST, PAN, CIN) substituted wherever the application asks for tax or registration details.

Does a DUNS Number Expire?

No. Once issued, a DUNS number remains valid for as long as your business exists, with no renewal fee. It can change only in cases of major structural change, such as a merger, acquisition, or dissolution of the legal entity it was issued to.

Free vs. Paid: What You Should Actually Expect to Pay For

Standard DUNS registration itself is free, full stop. The only legitimate paid option directly from D&B is expedited processing, which shortens the standard timeline for a fee. Beyond that, some third-party agencies charge a service fee to handle the free application on your behalf — which can be a fair trade if you’re short on time, but isn’t something you’re required to pay for just to get a DUNS number in the first place.
