php - VAT number validation API -

what can guys recommend?

found 1 http://isvat.appspot.com/ can validate european union numbers, seems not work properly.. returns false on valid dk vat numbers?

i need validate vat numbers outside eu

you can utilize european union website validate them directly: http://ec.europa.eu/taxation_customs/vies/

outside european union states don't have standardized number system, have validate each individually, see formats on wikipedia

php api validation
