Why Google is asking for your SIREN — e-invoicing in France is arriving for real

Electronic invoicing becomes mandatory in France on September 1, 2026 — vendors are collecting SIREN numbers to route invoices. The email wave is just starting.

Subject line of this morning's email: "Notice: Invoicing changes for your Google Cloud account in France starting September 1, 2026."

Google is asking for my SIREN (French company ID)? Why?

Electronic invoicing — your suppliers are starting to ask for your SIREN, this is the reform arriving, not spam

E-invoicing, of course

It becomes mandatory on September 1, 2026. And to route an invoice to the right company, you need a unique identifier: the SIREN.

So your vendors are cleaning up their records.

What to expect

If you run a company in France, brace yourself: this summer you'll receive a wave of emails — "update your tax information", "provide your SIREN". Google today, the others in the coming weeks.

It's not spam. It's the reform actually arriving.

And you — have you received your first ones, or am I early?
