Amazon is asking for my FDA registration number: which number do they mean

Updated 2026-08-24

Amazon’s box is not an FDA form

When Seller Central asks for an “FDA registration number,” that request comes from Amazon, not from FDA. FDA does not issue a single public number that proves a product may be sold on a marketplace.

What number, if any, exists depends on the product category. Handing Amazon the wrong identifier, or a number printed on a vendor’s “FDA certificate,” does not make the listing lawful. It only fills a field.

Food and dietary supplements: a facility number, not a product number

Facilities that manufacture, process, pack or hold food for consumption in the United States must register with FDA unless an exemption applies. Dietary supplement facilities sit inside that food-facility rule.

The number assigned at registration belongs to the facility. It is not a product SKU, not an approval, and FDA does not publish food-facility registration information. FDA’s own import page says food facility registration is confidential: you cannot look another firm’s number up, you have to ask the firm.

If Amazon is asking the brand owner for “your” number, the number they usually want is the contract manufacturer’s food facility registration, not a number the Amazon store invented.

Cosmetics: FDA uses the FEI

Under MoCRA, manufacturers and processors register cosmetic facilities and responsible persons list each marketed product. FDA intends to use the FDA Establishment Identifier (FEI) as the facility registration number. If the firm does not already have an FEI, it has to obtain one before registering.

FDA states, in plain language, that cosmetic facility registration and product listing is neither an approval programme nor a promotional tool, and that FDA does not issue certificates for those filings. A PDF headed “FDA certified cosmetic” is not an FDA document.

What is never the right number

An NDC is for drugs. A 510(k) number is for devices. A D-U-N-S number is the unique facility identifier FDA wants on a food-facility registration; it is not itself an FDA registration number. An EIN is a tax number. None of these is a substitute for the category-correct FDA filing.

FDA does not approve dietary supplements. There is therefore no supplement “FDA approval number” to paste into Amazon. If a supplier sold you one, it was not issued by FDA.

What we do when Amazon is blocking the listing

The first job is to name the product category correctly: food, dietary supplement, cosmetic, drug or device. The second is to identify which facility actually has to be registered, and which number that facility already holds.

Food or supplement facility registration is $299, or $499 bundled with a year of US agent. MoCRA cosmetic facility registration including one product listing is $549. Amazon or ecommerce claim review is $249 per listing, which is the right service if the block is about words on the page rather than a missing number.

Common questions

Can I look up another factory’s FDA food facility registration number?

No. FDA states that food facility registration is confidential and not available publicly. You have to ask the firm.

Is a D-U-N-S number the FDA registration number?

No. FDA requires a unique facility identifier on food facility registrations and recognises the Dun and Bradstreet D-U-N-S number for that. The DUNS identifies the plant. The FDA registration number is issued after the facility registers.

Does MoCRA give me a certificate I can upload to Amazon?

No. FDA does not issue certificates for cosmetic facility registration or product listing, and says those filings are not a promotional tool.

My supplier sent a document with an “FDA number.” Can I use it?

Only after you know which FDA programme it came from and that it belongs to the facility that actually makes or packs your product. Many of those documents are not FDA filings at all.

If I fill Amazon’s field, is the product FDA approved?

No. Filling a marketplace field does not change the legal status of the product. Registration is not approval.
