EU VAT number validation in Go using VIES SOAP service

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.
