# VATFind

> VATFind helps businesses find available VAT numbers and US EINs, match tax identifiers to legal-company records, and monitor company changes. Access company evidence through the web platform, REST API, Model Context Protocol (MCP) integration, and bulk data feeds.

Official website: https://vatfind.com/
Brand name: VATFind.
This index covers VATFind's public product information, documentation, guides, and policies.

VATFind supports supplier and customer onboarding, invoice checks, business-data enrichment, and company evidence for AI agents. Available company fields include legal name, registration number, country, registered address, legal status, VAT or tax identifiers, and source information. Field availability and monitoring capabilities vary by country and source.

Interpret company identity, company legal status, and tax-registration status as separate facts. A company-record match does not by itself establish a current tax-authority validation. Use the returned source, timestamps, and explicit result states. Missing fields or a service error must not be interpreted as an invalid tax number or an inactive company.

Use the linked pricing and coverage pages for current plan terms and supported capabilities. API requests require the documented authentication and applicable workspace access. This public index contains no customer records, credentials, or private workspace information.
