An FEI outlives the registration behind it
This blog has already covered how FDA registration and device listing are two separate duties a firm owes before it can sell in the U.S. at all, and the EU's own version of the same confusion, where a Single Registration Number registers a role rather than a company. The U.S. system carries a third distinction most facility files never separate out: an FDA Establishment Identifier and the device establishment registration built on it are two different records, running on two different clocks, and a file that keeps one field labeled “FDA number” has usually kept only the half that resets every year.
One number is assigned to the address, not the filing
FDA assigns a facility its own FDA Establishment Identifier — an FEI — the first time that physical location's information enters FDA's registration system, under whichever program brought it there first: drugs under 21 CFR Part 207, biologics under Part 607, or devices under Part 807. FDA's own guidance on identifying manufacturing establishments in applications is explicit that a facility already registered under one of those parts keeps that same FEI when it later registers under another. The number belongs to the address, not to the device operation that happened to trigger it, which is why a building that registers a drug operation first and adds a device line later doesn't get issued a second identifier for the second line.
The other number is a filing that has to happen every year
21 CFR 807.22 requires the owner or operator of a device establishment to update its registration and device listing annually, in a fixed window every fiscal year: October 1 through December 31. Missing that window isn't ambiguous under the regulation — the establishment moves into failed-to-register status and isn't considered active for the year it missed. Since the Medical Device User Fee Amendments, that annual renewal also carries its own fee, billed to every registrant and reset by FDA each fiscal year regardless of whether anything about the facility itself has changed. All of that — the window, the status, the fee — is entirely about the registration filing. Nothing in 807.22 touches the identifier the registration happened to be filed under.
A lapsed registration doesn't erase the identifier behind it
Because the FEI belongs to the facility rather than to a given year's filing, a firm that lets its device registration go inactive and later re-registers at the same address isn't issued a new FEI when it comes back. It reactivates registration under the number that was sitting on FDA's books the whole time, inactive registration and all. A facility file that treats a lapsed registration as though the underlying FDA record disappeared is confusing an annual status with a permanent identity, and only one of the two resets on its own each year.
The identifier is the more durable reference, even where the file doesn't expect it
Because the FEI persists across programs and across a given facility's lapses and reactivations, it's the reference FDA's own cross-program identification practice is built to keep stable — not whichever device registration number happens to be current in a given fiscal year. FDA's own import screening tool, PREDICT, pulls FEI numbers into the firm data it uses to match a shipment at the border to a known manufacturer, alongside names, addresses, and registration details for every party in the transaction; a device establishment's own filing status that year is one field among several the system considers, not the key it uses to find the facility in the first place. A facility record that only stores this year's registration number, and treats the FEI as an internal detail not worth keeping separately, has thrown away the one identifier that survives a missed renewal, a name change, or a switch between product lines at the same address.
Where this meets the file
A facility record needs the FEI carried as its own permanent field, distinct from the device establishment registration's annual renewal date and the October–December window it has to clear every year — not one cell that gets overwritten each fiscal year the registration renews. A facility registration tracker built around that split is previewed in the launch catalog. If your program tracks FEI and registration status differently, the shelf takes that correction directly.
