What is a VAT Number?

A VAT number is a distinct identifier given to businesses that are registered for VAT within the EU. It serves as the business’s VAT identity for invoicing and tax documents. In Ireland, a VAT number consists of the prefix IE, followed by eight numerical digits.

The Importance of VAT Number Verification

Verifying a VAT number is critical for several reasons:

  • Legal Compliance: It confirms that your business adheres to VAT regulations.
  • Fraud Prevention: It helps mitigate the risk of fraudulent activities which can have severe financial repercussions.
  • VAT Reclamation: It’s necessary for reclaiming any VAT that your business has incurred on EU purchases.

How to Verify a VAT Number in Ireland

Verification can be done through two primary channels:

  • VAT Information Exchange System (VIES): This online tool, provided by the European Commission, enables users to check the validity of a VAT number for any EU member state. Simply input the VAT number and the system will validate it, revealing the company’s name and address. Access the VIES website here.

  • Irish Revenue Commissioners’ Contact: For direct confirmation, reach out to the Irish Revenue Commissioners’ VAT registration unit. They can verify the VAT number’s authenticity and provide associated business details.

VAT Number Verification for Non-EU Businesses

Non-EU businesses engaging with EU customers may need to register for an Irish VAT number. The VIES platform also accommodates verification for these entities. Alternatively, the VAT registration unit of the Irish Revenue Commissioners can assist non-EU businesses with validation queries.

Consequences of Invalid VAT Numbers

Operating with an invalid VAT number can lead to severe repercussions, including:

  • Fines: Monetary penalties for non-compliance.
  • Back Taxes: Liability for unpaid taxes.
  • Legal Action: Potential for criminal charges in serious cases.

It is imperative for businesses to perform routine checks to ensure their VAT number remains valid and conforms to the latest regulations to avert these risks.


A valid VAT number is a cornerstone of legitimate business operations within the EU. Regular verification through reliable sources like VIES or the Irish Revenue Commissioners not only maintains regulatory compliance but also fortifies your business against fraud. Make VAT number verification an integral part of your business practice to ensure seamless transactions within the EU’s dynamic market environment.
