You can find most businesses’ VAT numbers on their invoices, receipts or website. To check a number is valid, use VIES for EU and Northern Ireland (XI) numbers, or HMRC’s “Check a UK VAT number” service for other UK numbers. Whether you need to find a VAT number, check company VAT number, or locate a VAT registration number, this guide will help you navigate the process confidently.

What Is a VAT Registration Number?

A VAT registration number is a unique identifier assigned to businesses registered for Value Added Tax (VAT). This number is critical for tracking and managing VAT-related transactions. Knowing how to locate and verify a VAT registration number ensures compliance and builds trust in business partnerships.

How to Find VAT Number

To find a VAT number, consider the following methods:

  1. Invoices and Receipts:
    • VAT-registered businesses must give customers an invoice showing how much VAT has been charged, and their VAT number is usually on it.
  2. Official Company Websites:
    • Many businesses show their VAT number on their website.
  3. Ask the Business Directly:
    • Neither VIES nor HMRC’s UK checker lets you search by business name, so if the number isn’t on an invoice, receipt or website, ask the company’s finance or accounting team.

How to Check Company VAT Number

Once you obtain a VAT number, verifying its validity is crucial. Here’s how to check company VAT number:

  1. Use the VAT Information Exchange System (VIES):
    • The European Commission’s VIES checks VAT numbers from EU Member States and Northern Ireland against the relevant national database and shows whether the number is valid. Depending on national data protection rules, some countries also show the name and address linked to the number.
  2. Use HMRC’s Check a UK VAT number service:
    • It confirms whether a UK VAT number is valid and shows the name and address of the business it’s registered to. UK VAT-registered businesses can also use it to prove when they checked a number.
  3. Try VATabout’s VAT Number Checker Tool:
    • Use our VAT Number Checking tool for quick and reliable VAT number verification. Simply enter the VAT number to instantly confirm its validity, ensuring compliance and saving time.

Why It’s Important to Check Company VAT Number

Checking a VAT number confirms that you’re dealing with a VAT-registered business. It matters most for cross-border sales: according to the European Commission, if you believe your customer is not a taxable person, you should not exempt the supply but should charge VAT.

Tools to Check VAT Numbers

  • VIES: the European Commission’s tool for VAT numbers from EU Member States and Northern Ireland.
  • HMRC’s Check a UK VAT number: for UK VAT numbers, including the registered name and address.

Best Practices for VAT Number Checks

  • Always cross-reference VAT numbers with invoices and official records.
  • Conduct periodic checks for all business partners to ensure compliance.
  • Use official tools such as VIES and HMRC’s checker for verification.

Conclusion

Understanding how to find a VAT number, check company VAT number, or locate a VAT registration number is vital for maintaining tax compliance and fostering reliable business partnerships. With VIES for EU and Northern Ireland numbers and HMRC’s service for UK numbers, you can confirm a VAT number is valid before you rely on it.
