Global Vat Validator

You'd reach for this when you need to validate VAT numbers across multiple countries, especially if you're dealing with Brazil's upcoming 2026 switch to alphanumeric tax IDs. It handles EU VIES checks, UK VAT validation, Indian GST numbers, and Brazilian CNPJ formats. The server exposes validation operations through a remote SSE transport hosted on Zuplo, so you can verify tax registration numbers without managing multiple country-specific APIs yourself. Useful for invoicing systems, e-commerce checkouts, or any billing pipeline that needs to confirm customer tax IDs are legitimate before processing transactions across borders.
