The Business Identifier list is empty and nothing can be typed
You open Register e-Invoice, click New Registration, agree to the contract, and reach the Participant Identifier step. The Participant ID is filled with 0225, but Business Identifier stays empty and you cannot type into it.
This field is not a text box. It is a list, and it can only offer identifiers that already exist in your company's PPF directory and are not registered yet. The note under the field states the rule: "Only active identifiers are available for selection. Previously used identifiers are not shown."
When the list is opened on a company that has spare identifiers, it looks like this — each entry carries its type, Code Routage or Suffixe:
Why your list is empty
Your SIREN and your SIRET are each registered only once. If both are already registered — which is the normal state after onboarding — there is nothing left for a new registration to use, so the list is empty. That is not an error; it means you already have the registrations those identifiers allow.
Check what you have on Register e-Invoice. Every row there is one registration that already exists:
Only one registration is used for sending and receiving at a time; the ACTIVE column marks which one.
How to get a selectable identifier
Register a further identifier under your SIREN first. Open Company Settings > PPF Directory. SIREN and SIRET come from INSEE and cannot be added by hand, but Code Routage and Suffixe are yours to define, and each one becomes a new selectable Business Identifier.
The FULL IDENTIFIER column shows the value that will appear in the Business Identifier list — your SIREN, joined with the SIRET, routing code or suffix.
- Click Add New Identifier.
- Choose the Identifier Type: an establishment
SIRET, aCode Routage, or aSuffixe. - Enter the value. A SIRET must be exactly 14 digits; a Code Routage must be attached to a SIRET that already exists in the list.
- Add an optional Label such as
Head OfficeorParis Branchso you can recognise it later. - Save, then return to Register e-Invoice > New Registration. The new identifier is now selectable.
A new identifier is not usable the instant it is saved. Each line carries its own STATUS and ACTIVATION DATE in the PPF directory, and only an Active line can be selected.
If you are moving from another provider
Do not start a new registration. The Register e-Invoice dialog has a second tab, Migrate from Provider, for a SIREN already registered through another plateforme agréée. Using New Registration in that situation is what produces the message that the participant identifier has already been used.
When to contact support
Contact support if the PPF Directory shows no rows at all, if a line stays out of Active status for more than a business day, or if an identifier you can see in the directory never appears in the Business Identifier list. Quote your SIREN and the full identifier you expected.
