How do you find a company vat number?

To find a company's VAT number, you can check their official website, as many businesses display their VAT information in the footer or on their contact page. Additionally, you can search for the company in public business registries or databases, which often provide VAT details. If you have a business relationship with the company, you can also request the VAT number directly from them. Lastly, in the EU, you can use the European Commission's VIES tool to validate and find VAT numbers for registered businesses.
