EU VAT guide

VIES consultation number

A VIES consultation number is an audit reference returned by the VIES approximate check flow when requester VAT details are supplied.

Why it matters

Finance teams often keep evidence that a VAT number was checked at a specific time.

The public VIES SOAP service includes a checkVatApprox operation that can return a requestIdentifier when requester VAT details are included.

MVP limitation

This free checker uses the standard checkVat flow and does not currently request consultation numbers.

Batch validation and audit-ready exports should be treated as a paid workflow after real demand is confirmed.
