Frequently asked questions about VIES VAT validator
What does “service unavailable” mean?
VIES or the member state could not respond. It does not mean the number is invalid; try again later.
Is the number I check stored?
No. Numonis does not log, store or send the number to analytics; it is sent only to VIES for the requested check.
Should I save the result?
It is advisable to retain evidence of checks connected with intra-EU transactions and repeat them when appropriate.
