Whether it be an in-house application, a database or a website based data entry form Data8 can help reduce the effort of capturing an address accurately and at the same time can ensure that it is stored in a standard format.

Using postcode lookup from Data8 also reduces the amount of data that needs to be entered by the customer. By collecting house number and post code and using the postcode lookup web service the full PAF validated address can be returned. By supplying a post code on its own a list of addresses will be presented to the user and all that they have to do is select the appropriate one.

With our range of integration options, from simple Javascript popups that you can add in minutes by copying & pasting code, or our ASP.NET controls, or our full web service interface, you can add postcode lookup options to your website in minutes. You can get started now by registering for a free trial.

AddressOutput result = proxy.GetFullAddressSimple(

    PostcodeTextBox.Text,
    HouseTextBox.Text);

// Check that the web service call worked, i.e. that all parameters were valid and
// we have sufficient credit.
if (!result.Status.Success)
    throw new ApplicationException(result.Status.ErrorMessage);

// Check that the web service returns at least one address, otherwise the postcode
// we have supplied is invalid.
if (result.Results.Length == 0)
    throw new ApplicationException("Invalid postcode or building details");

// Iterate over the list of addresses returned from the web service.
foreach (FormattedAddress address in result.Results)
{
    // The address is returned as an array of lines. We want to add them to a
    // listbox so reformat them into a single line separated by commas.
    StringBuilder builder = new StringBuilder();

    foreach (string line in address.Address.Lines)
    {
        if (String.IsNullOrEmpty(line))
            continue;

        if (builder.Length > 0)
            builder.Append(", ");
