How to verify a European VAT number using the VIES system
Run a VIES check before work starts, and make your VAT call from that result, not from assumptions. VIES is the European Commission's VAT validation web tool. It queries national VAT databases to show whether a number is recorded for cross-border EU trade. The operating rule is simple: if the result is **Valid**, move to the next compliance step. If it is **Invalid**, treat the VAT number as unconfirmed and resolve it with the client before deciding invoice treatment.
