I have created simple VIES VAT number validation script. Script allows to upload previously prepared CSV with countryCode and vatNumber and creates HTML table with validation results.

 

CSV example:

countryCode;vatNumber
AT;U20557305
AT;U55343505
AT;U63017835
AT;U63091969
AT;U67414700
AT;U68575437
AT;U73556289
BE;0502674883
BG;106030859
BG;115100705

PHP script:
