Golang VAT number validation

Uses the official VIES VAT number validation SOAP web service
to validate european VAT numbers.

Unfortunately their service is super unreliable.

Install

go get -u github.com/mattes/vat

Usage with Go

import "github.com/mattes/vat"
response, err := vat.CheckVAT("IE6388047V")
if err != nil {
  // do sth with err
}
fmt.Println(response.Name, response.Valid)
// or ...
valid, err := vat.IsValidVAT("IE6388047V")
// increase timeout (default 10 seconds)
vat.Timeout = 10
// get VAT rates for EU countries
rate, ok := vat.StandardRate("DE")
// get applicable tax and if reverse charge is allowed,
// depending on VAT number and country
// (use at own risk!)
rate, reverseCharge, err := GetApplicableTax("DE", "")
rate, reverseCharge, err := GetApplicableTax("IE", "IE6388047V")
rate, reverseCharge, err := GetApplicableTax("CH", "")

Usage via Console

There is a small cli included in this package.

Install with go get -u github.com/mattes/vat/vat-check
