VAT Number Check UK

Importance of a VAT Number

A VAT number is a unique identifier assigned to businesses registered for VAT in the UK. It enables businesses to charge VAT on their goods and services, as well as claim input tax credits for VAT paid on business-related expenses. For customers, a VAT number ensures that the business they are dealing with is legitimate and compliant with tax regulations.

How to Obtain a VAT Number in the UK

Businesses in the UK must register for VAT if their taxable turnover exceeds the current threshold of £85,000. Registration can be done online through the HMRC website. Once the registration process is complete, the business will receive a VAT registration certificate containing their unique VAT number.

Checking a VAT Number in the UK

VIES (VAT Information Exchange System)

The most convenient way to verify a UK VAT number is through the VAT Information Exchange System (VIES), a free online service provided by the European Commission. Simply enter the VAT number you wish to check, and the system will return its current status and validity.

HMRC (Her Majesty’s Revenue and Customs) Helpline

Another option for verifying a VAT number is to contact the HMRC VAT helpline. This method is particularly useful if you encounter issues or discrepancies when using the VIES system.

Why You Should Verify a VAT Number

Verifying a VAT number is crucial for businesses to ensure compliance with tax regulations, avoid potential penalties, and maintain accurate accounting records. For customers, checking a VAT number can help confirm the legitimacy of the business they are dealing with and provide peace of mind.

When to Check a VAT Number

It’s a good practice to verify a VAT number before entering

into a business transaction with a new supplier or customer. Regularly checking the VAT numbers of your existing partners can also help you stay compliant with tax regulations and maintain accurate records.

Common Issues with Number Verification

When verifying a VAT number, you may encounter some common issues, such as:

  • An incorrect or incomplete number
  • A recently registered or deregistered VAT number
  • Technical issues with the VIES or HMRC systems

In such cases, you may need to seek clarification from the business you are dealing with or consult the HMRC helpline for assistance.

VAT Number Format in the UK

A UK VAT number consists of nine digits, preceded by the letters ‘GB’. For example: GB123456789. When verifying a VAT number, ensure that it follows this format and includes the correct number of digits.

If you discover that a VAT number is invalid or inactive, it’s essential to address the issue promptly. Contact the business in question to seek clarification and, if necessary, request their updated VAT information. If you suspect any fraudulent activity, report it to HMRC immediately.
