UK VAT number checker

Authenticates and verifies one or more UK VAT (Value Added Tax) numbers using the official HMRC VAT check service.

This Actor accepts a list of VAT numbers as input and returns detailed validation results, including the company name and address for each valid VAT number.

🧠 Features

• ✅ Validates UK VAT numbers
• 🧾 Returns company name and address for valid entries
• 📊 Supports bulk validation in one run
• ⚡ Suitable for automation and integrations

🚀 How It Works

The Actor programmatically interacts with the official UK VAT check service to determine:

• Whether a VAT number is valid
• The registered business name (if valid)
• The registered address (if valid)

This makes it easy to integrate VAT checks into automation workflows, compliance checks, partner onboarding flows, or data enrichment processes.
