If you’re setting up an Amazon Business account and seeing a DUNS number field marked as optional rather than required, it’s fair to wonder what “optional” actually means here. Does skipping it limit what you can do later? Is it worth providing anyway? Here’s the honest answer: for most Amazon Business seller accounts, a DUNS number is genuinely optional — but providing one, when you have it, can strengthen your business profile and smooth out certain verification or B2B trust features down the line.
We cover the broader question of Amazon’s DUNS requirements in our guide, Does Amazon Require a DUNS Number? — this post focuses specifically on the “optional” field you’ll see on Amazon Business.
Why Amazon Marks It as Optional Instead of Required
Amazon Business is built to serve a wide range of sellers and buyers — from small proprietorships to large enterprises — and not all of them have or need a DUNS number to operate legitimately on the platform. Rather than blocking smaller businesses that don’t have one, Amazon treats it as supplementary information: useful for verification and credibility, but not a gatekeeping requirement for basic account setup.
This is different from platforms like Apple Developer or Google Play Console, where organization accounts specifically require DUNS-based verification. Amazon Business takes a more flexible approach, at least for standard account setup.
What Providing a DUNS Number Actually Does for You
Even though it’s optional, a DUNS number isn’t purely decorative on your Amazon Business profile. It can help in a few concrete ways:
- Stronger business verification: Buyers and procurement teams on Amazon Business sometimes look for verified business credentials before purchasing from a seller, especially for larger B2B transactions.
- Smoother experience with related programs: If you later apply for other Amazon programs like Global Selling or certain enterprise-focused features already having a DUNS number on file can save you a step, since some of those programs do require one.
- General business credibility: A DUNS number is recognized internationally as a marker of business legitimacy, which can matter if you’re dealing with larger institutional buyers who cross-check vendors against D&B’s database independently of Amazon.
When It Stops Being Optional
There are situations within the broader Amazon ecosystem where a DUNS number moves from “nice to have” to genuinely required:
- Amazon Global Selling, for certain regions and cross-border programs
- Larger enterprise or government-facing procurement relationships conducted through Amazon Business, where the buyer’s own compliance requirements may specifically ask for DUNS verification
- Brand Registry or certain verification-heavy programs, in specific cases
If you’re only doing standard Amazon Business selling without engaging these specific programs, you can typically proceed without one.
Should You Get One Anyway, Even If It’s Optional?
If you’re planning to grow beyond basic Amazon Business selling, expanding internationally, pursuing larger B2B or institutional buyers, or eventually enrolling in programs that do require DUNS verification, getting a DUNS number now, while it’s optional, can save you a scramble later. It’s free to obtain through D&B’s standard process, so there’s no real downside to having one ready even if nothing currently forces the issue.
If you’re a smaller business focused purely on domestic, standard Amazon Business selling with no near-term plans to expand into those areas, it’s reasonable to leave it for later and revisit only if a specific requirement comes up.

Is a DUNS number required to sell on Amazon Business?
Well, it is not required for most “standard” Amazon Business seller accounts. It becomes more relevant for certain enterprise-focused features and/or specific programs such as Global Selling.
Does having a DUNS number improve my Amazon Business seller profile?
It can assist in building buyer trust and business verification for larger B2B sales, but it does not necessarily need to be used for transactions that are just a matter of selling.
Will I need a DUNS number later even if I don't need one now?
Perhaps, if you grow into programs such as Global Selling or target institutional buyers that need DUNS-verified vendors. One early is worth more than another.
Is getting a DUNS number free even if I only want it as a precaution?
Yes, it is FREE to have a standard DUNS registration with D&B; it’s not always required for something you are doing.
