# France

> What Coverbase asks a supplier in France for, and which of those rules block a submission.

[User guides](/user-guides/overview) / [Supplier countries](/user-guides/supplier-countries/overview)

A supplier whose bank account is held in France sees the fields below. The country is chosen on the form, and changing it changes the fields, so a supplier is never asked for a detail their country does not use.

## Bank details

| Field                 | Requirement | Format                                     | Notes                                                             |

| Account number        | Required    | up to 11 characters, letters and digits    |                                                                   |
| Check digit           | Optional    | 2 characters, digits only, RIB key check   |                                                                   |

| Account type          | Optional    | no length limit, one of: checking, savings | Checking unless the bank issued the account as a savings account. |

### IBAN

An IBAN is required for France. It is 27 characters and is checked against the ISO 7064 MOD-97 algorithm, which catches a mistyped or transposed digit before the details reach your finance system.

## Tax and company registrations

| Registration | Requirement | Format                                                  | Notes     |
| ------------ | ----------- | ------------------------------------------------------- | --------- |
| SIREN        | Required    | 9 characters, digits only, SIREN Luhn check             | 9 digits. |
| SIRET        | Optional    | 14 characters, digits only, SIREN Luhn check            |           |
| VAT number   | Suggested   | 13 characters, letters and digits, French VAT key check |           |

After a registration is saved, Coverbase checks it against the EU VIES service in the background. That check never blocks the supplier: it annotates the record once it completes, and a reviewer can retry it.

## Where these rules come from

Oracle Fusion Cash Management 26c FR validations; INSEE SIREN, DGFiP VAT key.

The rules on this page are confirmed against a primary source, so they are enforced strictly.
