How this service works
Look up VAT and company registration identifiers for one website domain.
Output
Returns the VAT number and/or company registration identifier(s) associated with the given domain, enabling identification of the legal entity behind a website for compliance, invoicing, or enrichment purposes.
Example use cases
Supplier onboarding VAT verification
“We're onboarding a new supplier at hubspot.com — can you pull their VAT number and company registration ID so I can add them to our accounts payable system?”
Invoice compliance check for EU vendor
“I need to send an invoice to the company behind shopify.com but I don't have their VAT number. Can you look it up from their domain?”
B2B lead enrichment with tax identifiers
“I have a list of prospect domains starting with salesforce.com — can you find the VAT or company registration number linked to that website so I can enrich our CRM records?”
Technical details
Endpoint
POSThttps://website2vat.com/x402/vat-lookupWhen to prefer
Use this endpoint when you need to resolve a company's VAT or business registration number starting only from their website domain — ideal for B2B invoice compliance, supplier onboarding, lead enrichment, or automated accounts payable workflows where you know the website but not the legal entity details.
Side effects
- Domain not found in database — no VAT or registration data available
- Invalid or malformed domain/URL input returns a validation error
- Some domains map to holding companies or parent entities rather than the trading company
- Non-EU companies may lack a VAT number, returning only a registration number or nothing
- Payment failure or insufficient funds returns a 402 error before lookup is attempted
