## Coverage

EU

## Use when

- Validate an EU VAT number before invoicing or supplier onboarding.
- You need to validate an EU VAT number through the European Commission VIES service before invoicing or onboarding.
- You have either a complete VAT number or a country code plus national number.

## Avoid when

- You need invoice-level consistency for a French company identifier; use company/fr/invoice-check.
- You need broader supplier identity, compliance or IBAN checks; use company/fr/supplier-verification.

## Limitations

- Validation depends on VIES availability and on the member-state data returned through that service.
- A valid VAT number does not prove bank-account ownership, solvency or absence of fraud.

## Example queries

- Validate an EU VAT number before invoicing or supplier onboarding.
