Validate the format of an EU VAT number by country online, in your browser.
Check that an EU VAT number has the correct shape for its country. Enter the number with its two-letter country prefix; the tool reports the country, the number and whether the format is valid.
No — it validates the format only. To confirm registration you need the EU VIES service; this is a fast first filter for typos.
With the country prefix, e.g. DE123456789 or FRXX999999999.
