What EU Verifier provides
A free, independent reference that reduces input errors before you run an official verification. We guide you to official sources — we do not issue identifiers or act as an authority.
Format sanity checks
Catch wrong prefixes, missing digits, spaces, or character errors before sending your number to an official service. Each identifier type has specific structural rules validated here.
Direct links to official tools
Every tool on this site routes you to the authoritative verification source: VIES for EU VAT, the European Commission for EORI, GLEIF Search for LEI, and HMRC for UK VAT.
Compliance guidance
Understand what each identifier type means, when it is required, and how to interpret verification results. Useful for onboarding, invoicing, customs, and financial workflows.
How verification works
A consistent four-step process for any European business identifier.
Choose the identifier type
VAT for EU tax and intra-EU B2B, EORI for customs, LEI for global financial entity identification, UK VAT for post-Brexit UK entities.
Run a format check
Paste the number into the relevant tool on this site. We validate the structure against the official format spec for each country or identifier system.
Verify via the official service
Click through to the official government or registry service. Only official sources can confirm whether an identifier is actively registered.
Record evidence
For compliance and audit trails, record the date, identifier, and result. Many tax authorities expect VAT check evidence as part of invoicing records.
Which identifier do you need?
Different business contexts require different identifiers. This table helps you choose the right verification path.
Independence notice
EU Verifier is not affiliated with the European Commission, any Member State tax administration, customs authority, GLEIF, or HMRC. We do not issue or validate identifiers — only official authorities can do that.
How we check formats
We apply country-specific regular expression patterns based on published official format specifications. A passing format check indicates the number structure is plausible — it does not confirm registration or active status.
Privacy and data
Identifier numbers you enter are processed locally in your browser. We do not transmit numbers to our servers or store them. See our Privacy Policy for full details.
Official service availability
Official verification services are occasionally unavailable for maintenance. Our Status page monitors VIES, EORI, GLEIF, and HMRC availability in real time.
