European(EU) VIES API VAT validation for dotnet based on the most current information from the official source

Installing

The fastest way of getting started using Vies api is to install the NuGet package.

Package Manager:

Install-Package vies-dotnet-api -Version 2.3.1

.NET CLI:

dotnet add package vies-dotnet-api --version 2.3.1

Package Reference

<PackageReference Include="vies-dotnet-api" Version="2.3.1" />

Usage

Checking a VAT number using the vies-dotnet-api

Checking if a EU VAT number is valid

 var result = ViesManager.IsValid("RO123456789");

or

 var result = ViesManager.IsValid("RO","123456789");

Checking if a EU VAT number is active

var viesManager = new ViesManager();

var result = await viesManager.IsActiveAsync("RO123456789");

or

var result = await viesManager.IsActiveAsync("RO","123456789");

Clarification

Since January 1, 2021 the UK is no longer a member of the European Union and as a result, the VIES service provided by the European Commission no longer validates VAT ID's for the UK.

Checking GB VAT number

...
var validationResult = await viesManager.IsActiveAsync("GB434031494");

will return the following message:

Great Britain(GB) is no longer supported by VIES services provided by EC since 2021-01-01 because of Brexit.
