EU VAT Number Validator (Bulk VIES)

Validate EU VAT numbers in bulk against the official VIES database for B2B invoicing, KYC compliance, and CRM enrichment. Drop in a list of VAT numbers and get back validity status, company name, and registered address for all 27 EU member states plus Northern Ireland. Processes hundreds of validations per run with configurable concurrency.

Features

• Official VIES source — validates directly against the European Commission's VAT Information Exchange System
• Company details — returns registered company name and address where available
• Bulk processing — validate hundreds of VAT numbers in a single run
• Audit trail — generates VIES consultation numbers for compliance documentation
• Flexible input — accepts VAT numbers with or without country code prefix
• Configurable concurrency — control request speed to avoid VIES rate limits

Input

Field	Type	Required	Default	Description

countryCode	string	No	—	Default 2-letter EU country code to use when not included in the VAT number (e.g., DE, FR, EE)
includeName	boolean	No	true	Request company name from VIES. May not be available for all countries
includeAddress	boolean	No	true	Request registered company address from VIES. May not be available for all countries

Notes

• VIES data comes directly from each member state's tax authority. Some countries (notably Germany and Spain) do not share company name or address.
• The VIES service can be temporarily unavailable for individual countries. The actor retries on transient errors.
• For high-volume use (10,000+ validations), keep concurrency at 2-3 to avoid rate limits from the VIES service.
