VAT Verification — VIES check and validation of third-party VAT numbers

**VAT Verification** secures VAT compliance across your Dolibarr third-party database. The module analyzes, normalizes and validates intra-community VAT numbers, then checks each number against the European Commission's official **VIES** service to confirm it exists and is active.

Built for accounting, finance and sales teams, it reduces the risk of rejected invoices, reporting errors and VAT fraud.

**Key features**
- Bulk scan of every **VAT-liable** third party that has a VAT number on file.
- Automatic normalization: removes spaces, dots and hyphens, converts to uppercase.
- Country-based structural validation (all EU member states + Northern Ireland "XI").
- Smart suggested corrections: adds missing leading zeros, adds the country code from the third party's address, fixes the Greek prefix (GR → EL).
- **Real-time VIES verification** through the European Union's official REST API (no SOAP dependency).
- Status shown directly on the third-party card and list (native hook).
- Results page with sorting, summary (valid / invalid / not confirmed) and a detailed record.
- Error messages **translated into the user's language**.
- Integrated into the **CRM** menu, fine-grained permissions, CSRF/XSS security and multi-company support.

**Compatibility**
Dolibarr 16.0 to 23 and later · PHP 7.4+.

**Support**
