VAT ID Number validation EU/GB

Question / Problem

Where can I check my VAT ID number (for the EU or UK) and find more information about it?

Answer / Solution

Please use the European Commission portal at https://ec.europa.eu/taxation_customs/vies/?locale=en to check your valid inner-European VAT ID number.

VAT IDs from the UK can be checked at https://www.gov.uk/check-uk-vat-number.
