What Is a DUNS Number and Why Food Exporters Need One Before FDA Registration

A DUNS number for FDA registration is the first technical requirement most foreign food exporters run into — and the one that causes the most unexpected delays. Before a facility can submit its FDA food facility registration, it must have a valid DUNS number issued by Dun & Bradstreet. Without one, the registration process cannot begin.

What a DUNS number actually is

A DUNS number is a unique nine-digit identifier assigned by Dun & Bradstreet (D&B) to individual business establishments worldwide. It stands for Data Universal Numbering System. Originally designed for commercial credit reporting, the DUNS number has been adopted by the US government — including the FDA — as a standard way to verify that a business entity is real, located where it claims to be, and distinct from other entities with similar names.

Each DUNS number is tied to a specific physical location. If a company operates three factories, each factory needs its own DUNS number. The number is not transferable: if a facility changes ownership or moves to a new address, the old number becomes invalid and a new one must be obtained. This location-specific design is exactly why the FDA uses it — the agency wants to track individual facilities, not corporate holding structures.

Why the FDA requires a DUNS number before registration

The FDA uses DUNS numbers to cross-reference facility data across multiple government systems. When a foreign food facility registers with the FDA, the agency checks the DUNS record to confirm that the facility name, address, and entity type match what was submitted. This cross-referencing is part of the FDA's broader effort to maintain an accurate, real-time map of the global food supply chain. Without it, the FDA would have no reliable way to distinguish between facilities with similar names or to verify that a registration corresponds to an actual operating site.

The requirement is not optional. The FDA's electronic registration system will not accept a submission without a valid DUNS number. If the number is missing, expired, or tied to a different entity, the registration stalls before it even reaches a reviewer. This is not a soft requirement that can be worked around — it is a hard gate in the system.

What goes wrong during the DUNS application

The DUNS application itself is free, but it comes with pitfalls that catch many foreign exporters off guard. The most common problem is name formatting. D&B records business names exactly as submitted, including punctuation, capitalization, and character encoding. If the name on the DUNS record uses a translated English version of the company name while the FDA registration uses the original local-language name — or vice versa — the mismatch will cause the FDA system to flag the submission.

Address formatting creates similar problems. Many countries use address structures that do not map cleanly onto the US-style format that D&B and the FDA expect. Province names, postal codes, building identifiers, and district names often get rearranged or abbreviated differently across the two systems. A DUNS record showing 'Industrial Zone 3, Block B' while the FDA registration says 'Block B, Industrial Zone 3' can be enough to trigger a verification hold.

Entity type confusion is another frequent issue. D&B classifies businesses by type — manufacturer, wholesaler, retailer, headquarters, branch — and the classification must reflect what the facility actually does. If a factory is accidentally classified as a headquarters or a trading office, the DUNS record will not align with the FDA's expectation that the registrant is a food manufacturing or storage facility.

Processing times and timing risks

Standard DUNS number applications can take 30 days or more to process, though expedited options exist at additional cost. Many exporters do not discover the DUNS requirement until a US buyer asks for proof of FDA registration — and by then, a 30-day wait for the DUNS number alone can push the entire market entry timeline back by weeks. Add the FDA registration processing time on top of that, and a facility that expected to ship within a month is looking at two months or longer.

Corrections add more time. If the initial DUNS application contains errors — a misspelled name, a wrong postal code, an incorrect entity classification — fixing those errors requires a separate update request to D&B, which has its own processing window. Each correction cycle adds days or weeks to the timeline, and none of that time can be used productively toward the FDA registration because the DUNS number must be correct before the FDA submission can proceed.

How DUNS data affects ongoing compliance

The DUNS number is not just a one-time filing requirement. The FDA periodically cross-references DUNS data against its registration records, and if the two fall out of sync — because D&B updated the record, because the facility moved, because the company name changed — the registration can be flagged for review. Keeping the DUNS record accurate and aligned with the FDA registration is an ongoing obligation that many facilities overlook after the initial filing.

Import documentation also references the DUNS-linked facility data. If the DUNS record shows one company name and the import paperwork shows another, customs processing slows down and shipments can be held for additional verification. The data chain from DUNS to FDA registration to import entry must be consistent end to end.
