EU VAT guide
VIES service unavailable
VIES can be unavailable because the EU gateway is down, a national registry is offline, or a temporary maintenance window is active.
What to do
Wait a few minutes and retry. If the same country keeps failing, the member-state registry may be unavailable.
For urgent cases, contact the relevant national tax administration or ask the customer for supporting registration evidence.
