VIES VAT checker UK
UK businesses trading with EU suppliers and customers often search for a VIES VAT checker UK tool — a way to validate European VAT numbers from Britain without logging into multiple systems. Since Brexit, the picture is slightly more complex: EU numbers still go through VIES, but GB numbers require HMRC. Here is what you need to know and how to check both free from the UK.
What is VIES and does it cover the UK?
VIES (VAT Information Exchange System) is the European Commission's official cross-border validation service for EU member states. When you enter a number starting with IE, DE, FR, or any of the 27 EU country codes, VIES routes the query to the relevant national registry and returns valid or invalid status plus registered business details where available.
Since Brexit, GB VAT numbers are no longer checked through VIES. UK registrations are validated through HM Revenue & Customs (HMRC) instead. A VIES UK VAT check for a GB prefix will not return a valid result — you need an HMRC lookup. Read VIES vs HMRC: what's the difference? for the full breakdown.
Why UK businesses still need VIES
Even though the UK left the EU VAT information exchange system, British companies still trade B2B with Ireland, Germany, France, the Netherlands, and every other member state. A VIES checker for UK businesses remains essential for verifying EU suppliers before payment, confirming customers before zero-rated cross-border sales, and preventing invoice fraud. If you buy from or sell to Europe, VIES is still your official source for EU VIES VAT validation from the UK.

Checking GB numbers from the UK — HMRC
When you need to verify a domestic or UK supplier, use HMRC — not VIES. GB numbers follow the format GB plus nine digits, for example GB116300129. A live HMRC check confirms the registration is active and returns the registered company name and address.
