# France VAT number (TVA intracommunautaire): format, use and checks

How the French VAT number works: the FR format built from the SIREN, how a company gets it, when it goes on invoices and how to check EU customers on VIES.

## Key takeaways

- The French VAT number is FR, a two-character key and the company's nine-digit SIREN.
- The tax office (SIE) assigns it when the company registers for VAT.
- It appears on invoices, and both parties' numbers appear on reverse-charge invoices to EU businesses.
- Check each EU customer's number on VIES before invoicing without VAT.

"France VAT number" is one of the top suggestions after "France VAT", alongside refund questions from tourists. For businesses, the number matters on every cross-border invoice.

## The format

| Part | Example |
|---|---|
| Country code | FR |
| Key | 12 |
| SIREN | 345678901 |
| Full number | FR12345678901 |

The key is calculated from the SIREN. Some keys contain letters.

## Getting it

The SIE assigns the number when the company registers for VAT, usually during formation through the guichet unique. It is visible in the company's professional space on impots.gouv.fr.

## Using it

- On every invoice you issue as a VAT-registered business.
- With the customer's number on reverse-charge invoices to EU businesses, plus "autoliquidation".
- In the European services declaration for B2B services to other EU countries.

## Checking customers

A Paris agency invoicing a client in Belgium checks the Belgian number on VIES. If valid, it applies the reverse charge. If not, it asks the client before invoicing, since the VAT treatment depends on it.

## Getting paid

EU customers pay by SEPA into an IBAN; with SEPA Instant, the money often arrives in seconds. Customers outside the euro area pay more cheaply into local details in their own currency.

## Paying into France: the local rail

## Where Rivet fits

Rivet gives French companies EUR details with an IBAN on Growth, plus GBP and USD details, so customers in and outside the EU pay locally. Rivet is not a bank; regulated partner institutions hold the funds. See [EU VAT OSS for non-EU sellers](/blog/eu-vat-oss-for-non-eu-sellers).

## Questions

### How do I find my French VAT number?

On your professional space at impots.gouv.fr, or on letters from your SIE. It is derived from the SIREN.

### Is the VAT number the same as the SIRET?

No. SIRET identifies an establishment (SIREN plus 5 digits). The VAT number is FR, a key and the SIREN.

### How do I check a customer's VAT number?

On the European Commission's VIES service. Save the result as evidence.

### Do I need it to sell outside the EU?

Your invoices always show it if you are VAT registered, but non-EU customers do not need theirs on your invoice.
