Check a UK VAT number
Use this service to check:
- if a UK VAT registration number is valid
- the name and address of the business the number is registered to
This service is also available in Welsh (Cymraeg).
If you are a UK VAT-registered business, you can also use this service to prove when you checked a UK VAT number. You will need your own VAT number to do this.
Before you start
You’ll need the VAT number you want to check before you use the service. You cannot use this service to check if a business or organisation is registered for VAT by searching its name.
You can find the VAT numbers for most businesses and organisations on their invoices, receipts or website.
You cannot use this service if you’ve already applied to register for VAT and you’re waiting to hear back from HMRC. Check when you should expect a reply.
