Need a VIES Consultation Number?

This public check confirms whether a VAT number is valid, but it doesn't issue a VIES consultation number – the reference VIES returns to document who checked a VAT number, and when. That reference is returned only on authenticated API calls where the caller sets their own EU VAT as the requester, so it documents your own check rather than ours.

Set your EU VAT once in dashboard Account details and every qualified check returns it – no code change. Retention obligations vary by jurisdiction, so check with your tax advisor on what your records need.
