VIES is not a central database
VIES queries national VAT databases when a check is made. Some member-state data can be unavailable, delayed, or returned in different formats.

Invalid does not always mean typo
A number can be missing, inactive for cross-border trade, or not yet finalised in a national registry. Ask the customer to verify with their tax office when needed.
