This feature enables businesses to validate customer and vendor VAT/GST registration numbers directly against supported tax authority systems.

Validating VAT/GST registration numbers helps businesses improve tax accuracy and support compliance requirements. In many jurisdictions, VAT treatment and reporting obligations vary depending on whether the customer or vendor is registered as a business or treated as a consumer. This feature helps businesses verify registration validity and make more informed tax determination decisions.

As part of the initial release, VAT number validation is available for EU VAT numbers through integration with the VIES (VAT Information Exchange System). Support for additional countries and tax authority systems will be added in future releases.

You can access the feature from Data Validation from the left navigation panel.

The validation workspace supports:

• Single VAT/GST number validation
• Batch validation of multiple VAT/GST numbers
