Address and Postal Code Validation for New Zealand

https://www.addy.co.nz/

Address cleansing, also called address validation or address matching, helps to transform incomplete, improperly formatted or duplicate addresses stored in a database into accurate addresses validated against official address databases, such as the New Zealand Postal Address File (PAF).

Make it easy for users to find and validate their address in your .NET, C# or VB.NET application.

   var criteria = Console.ReadLine();
   if (string.IsNullOrWhiteSpace(criteria)) return;

   var result = await validationService.AddressValidateAsync(criteria);

   if (result.address == null)
   {
      Console.WriteLine("No match found. " + result.reason);
