Do Amazon Sellers Need a DUNS Number?

The short answer: not always, but in several important scenarios, yes. While a basic Amazon Seller Central account does not require a DUNS number, Amazon's more advanced programs, including Vendor Central, Amazon Business, and certain verification processes, do use DUNS numbers to verify seller identity. And even when it is not strictly required, having a DUNS number gives your Amazon business tangible advantages in credibility, credit access, and cross-platform expansion.

This article breaks down exactly when you need a DUNS number as an Amazon seller, how it benefits your business, and how to get one.

Amazon Seller Verification Requirements

When you register as a third-party seller on Amazon Seller Central, Amazon verifies your identity through a combination of:

  • Government-issued photo ID
  • Bank account or credit card information
  • Business address verification (utility bill or bank statement)
  • Phone number verification
  • Tax information (EIN for US businesses, or equivalent for international sellers)

For most individual and small-business sellers, this standard verification does not involve a DUNS number. Amazon relies on its own identity verification systems and does not pull data from Dun & Bradstreet for basic seller accounts.

However, that changes once you move beyond the basics.

When Amazon Requires a DUNS Number

Amazon Vendor Central

Vendor Central is Amazon's invite-only, first-party selling platform. Instead of listing products yourself, you sell inventory directly to Amazon at wholesale prices, and Amazon handles the retail side. Vendor Central involves larger purchase orders, net payment terms, and a formal business relationship with Amazon.

During the Vendor Central onboarding process, Amazon frequently requests a DUNS number to verify that your business is a legitimate, established entity. Amazon uses the D&B database to confirm your company's legal name, address, financial standing, and operational history. A DUNS number with a strong business profile can influence whether Amazon extends favorable terms.

If you have been invited to Vendor Central and do not yet have a DUNS number, you should get one before starting the onboarding process.

Amazon Business Seller Registration

Amazon Business is a marketplace tailored for business-to-business (B2B) transactions. It allows sellers to offer quantity discounts, business-only pricing, tax-exempt purchasing, and other features relevant to enterprise buyers.

When registering as an Amazon Business seller, Amazon may request a DUNS number as part of enhanced business verification. This is especially common for sellers who want to participate in government procurement and institutional purchasing, where verified business credentials are non-negotiable.

Amazon Lending and Financial Services

Amazon offers lending programs to qualifying sellers. When evaluating sellers for loans or credit lines, Amazon may pull business credit data that is tied to your DUNS number. A DUNS number with a positive credit history through Dun & Bradstreet can improve your chances of qualifying for better rates and higher limits.

Amazon Brand Registry and DUNS Numbers

Amazon Brand Registry protects your intellectual property and gives you greater control over your product listings. To enroll, you need an active registered trademark. While Brand Registry itself does not require a DUNS number, having one strengthens your application in indirect ways:

  • It proves your business is a verified, operating entity, which can help resolve disputes faster.
  • If Amazon questions the legitimacy of your brand or business, a DUNS number provides an independent, third-party verification point.
  • Sellers with established business credit profiles (which are tied to DUNS numbers) tend to receive quicker resolutions from Amazon support on IP and listing issues.

For sellers serious about brand protection, a DUNS number is a practical complement to your Brand Registry enrollment.

Benefits of a DUNS Number for Marketplace Sellers

Even when Amazon does not explicitly require a DUNS number, there are several reasons to get one:

Building Business Credit

Your DUNS number is the foundation of your business credit profile with Dun & Bradstreet. A strong D&B credit score (called a PAYDEX score) opens doors to better financing, vendor terms, and business credit cards. For Amazon sellers who need inventory financing, this can be the difference between scaling your business and being stuck at your current level.

Credibility with Suppliers and Manufacturers

When negotiating with suppliers, especially international manufacturers, a DUNS number signals that you are a real business with a verifiable track record. Many suppliers in China, India, and Southeast Asia check D&B profiles before extending payment terms or agreeing to custom manufacturing runs.

Government Contract Eligibility

If you sell products that could serve government agencies, a DUNS number (or its successor, the SAM.gov UEI) is required for federal procurement. Many Amazon sellers diversify their revenue by bidding on government contracts, and the DUNS number is the entry point for that process.

Cross-Platform Expansion

A DUNS number is not just useful on Amazon. If you plan to expand to Walmart Marketplace, publish apps, or pursue wholesale distribution, you will need one. Getting it now saves time later. For details on how this applies to small businesses more broadly, we have a dedicated guide.

How to Get a DUNS Number as an Amazon Seller

The process is straightforward and free:

  1. Check if you already have one. Many businesses receive a DUNS number automatically through credit applications or vendor registrations. Use the free DUNS lookup tool to search by your legal business name and address.

  2. Request a free DUNS number from D&B. If no number exists, go to https://www.dnb.com/duns.html and submit a request. You will need your legal business name, physical address, phone number, and the name of a principal contact.

  3. Wait for processing. Free requests typically take 5 to 14 business days for US businesses. D&B may call or email to verify your information. Respond promptly to avoid delays.

  4. Receive your number via email. Once approved, D&B sends your nine-digit DUNS number by email. Save it securely. You will use it for Amazon programs and potentially many other business purposes.

Other Marketplace Requirements: Walmart, eBay, and Beyond

Amazon is not the only marketplace where a DUNS number comes into play. Here is how other major platforms handle it:

Walmart Marketplace

Walmart requires a DUNS number during seller registration. Unlike Amazon, this is not optional. When you apply to sell on Walmart.com, you must provide a valid DUNS number as part of the business verification process. Walmart uses D&B data to confirm your business identity and operational history before granting marketplace access.

If you are an Amazon seller looking to expand to Walmart, get your DUNS number sorted out first.

eBay

eBay does not require a DUNS number for standard seller accounts. However, eBay's managed payments system and its business seller verification process may reference D&B data in certain markets, particularly for high-volume sellers and those in regulated categories.

Shopify and Direct-to-Consumer Platforms

Shopify and similar platforms do not require DUNS numbers. However, if you use Shopify Payments or apply for Shopify Capital, the underlying financial institutions may check your D&B business credit profile.

Google and Apple App Stores

If you sell digital products or have a companion app, both Google and Apple may require DUNS numbers for organization developer accounts. This is especially relevant for Amazon sellers who build branded shopping apps.

Common Questions

Does Amazon check my DUNS number during standard seller registration?

No. Basic Seller Central registration does not involve a DUNS number lookup.

Can I use my DUNS number across all Amazon programs?

Yes. The same nine-digit DUNS number works for Vendor Central, Amazon Business, lending applications, and any other program that requests it.

What if my DUNS number has incorrect information?

Contact Dun & Bradstreet at 1-866-705-5711 to update your records. Incorrect data in D&B's system can cause verification failures on Amazon and other platforms.

Do I need a DUNS number if I sell as an individual?

If you are a sole proprietor selling casually on Amazon, you probably do not need one. But if you plan to grow your business, apply for credit, or expand to other marketplaces like Walmart, getting a DUNS number now is a smart move.

Is the DUNS number the same as my EIN?

No. Your EIN (Employer Identification Number) is a tax ID issued by the IRS. Your DUNS number is a business identifier issued by Dun & Bradstreet for credit and verification purposes. They serve different functions, and you will need both for most serious business activities.

Next Steps

Whether you need a DUNS number for Amazon Vendor Central today or just want to future-proof your business for growth, the process is free and straightforward. Check if you already have a DUNS number using our lookup tool, and if you do not, request one from D&B. It takes a few minutes to apply and a couple of weeks to receive, but it is a credential that pays dividends across every platform you sell on.
