# Validate a Supplier VAT Number List Against VIES

**Use case:** 

Check a whole supplier or customer list against the official VIES service in one run, and compare each registered name with the name you hold on file. Add your own EU VAT number and every row also carries a VIES consultation number, the reference a tax authority accepts as evidence you checked before zero-rating an invoice. A member state that does not answer reads as unavailable, not invalid.

## Input

## How to integrate an Actor?

This Task's input is already configured above. Use it as-is rather than inventing a new one.

Do not guess an integration path. Every one of them is in the agent quickstart at https://apify.com/agents.md: the Apify MCP server, Agent Skills with the Apify CLI, the JavaScript and Python clients, the REST API, and the account-free path for an agent with no human to sign in. It also carries the rule on stating cost before the first paid run.

For full API examples (JavaScript, Python, CLI, MCP, OpenAPI), see this Task's Actor page: https://apify.com/fayoussef/eu-vat-compliance-monitor.md

Each client library has reference documentation the quickstart does not restate: [JavaScript/TypeScript](https://docs.apify.com/api/client/js/docs.md) (`npm install apify-client`) and [Python](https://docs.apify.com/api/client/python/docs.md) (`pip install apify-client`).
