## VAT number validation, EU VIES

VAT number validation, EU VIES. $0.01 per successful call; failed calls are never charged.

Any spacing (SE556703748501, DE 123 456 789; EL or GR for Greece, XI for Northern Ireland). Or verify a business by name: found or not in the French, Swedish, Norwegian and Finnish registers.

## Questions

**Which countries does it cover?** Every EU member state and Northern Ireland (prefix XI) through VIES. Greece is EL; a number sent with GR is checked as EL.

**What if VIES or a member state is busy?** The check is retried for busy signals. If no clear answer comes, the call fails and is not charged; it never answers not valid by default.

**Does every country return the name and address?** No. Each member state decides; Germany and Spain return valid or not valid only.
