Tax not calculated when Zip code is 5+4

Hi,

I have noticed that when a customer enters a Zip+4 in their address, during checkout, the system will not calculate tax.  This works perfectly if they only enter the first 5 digits of the Zip code (my customers are in USA).

This makes sense as my tax setup is using Tax by County & State & Zip and I have tax rates for each Zip code I collect for but the zip codes only have the 5 digits.

How can I force the Zip Code field to only allow 5 Digits?

I looked at Nop.Web.Validators.Customer.CustomerInfoValidator and added a rule for the Zip code as follows:

if (customerSettings.ZipPostalCodeRequired && customerSettings.ZipPostalCodeEnabled)
{
RuleFor(x => x.ZipPostalCode).NotEmpty().WithMessage(localizationService.GetResource("Account.Fields.ZipPostalCode.Required"));
RuleFor(x => x.ZipPostalCode).length(5).WithMessage(localizationService.GetResource("Account.Fields.ZipPostalCode.Length"));
}

However, the rule did not fire when I tested.

Any ideas on how to resolve my problem?

Where exactly are you adding this new rule?
..in the solution (and then re-compiled it), or directly in a view?

Look for this section in the /Views/Shared/_CreateOrUpdateAddress.cshtml

    @if (Model.ZipPostalCodeEnabled)
    {
        <div class="inputs">
            @Html.LabelFor(model => model.ZipPostalCode, new { }, ":")
                @Html.EditorFor(model => model.ZipPostalCode)
            @if (Model.ZipPostalCodeRequired)
            {
                @Html.RequiredHint()
            }
            @Html.ValidationMessageFor(model => model.ZipPostalCode)
        </div>
    }

Try injecting your if/then condition there.

I added the rule inside the class at Nop.Web.Validators.Customer.CustomerInfoValidator

Then I recompiled and moved the nop.web.dll to my test server and tested it.  (It takes too long for my machine to run the website within Visual Studio so I find myself copying DLLs to my test server to test things and if it doesn't work, then I debug it).  

I guess I'll have to step through it in debug...

My question is though, is this the right place to add this; Nop.Web.Validators.Customer.CustomerInfoValidator?

Looking closely, I found another validator that was related at Nop.Web.Validators.Common.AddressValidator, I added my rule and now the form will not submit unless the Zip code length is 5.

That will do for me!

Just wanted to add this bit to limit the validation to a specific state.
For example, California:

RuleFor(x => x.ZipPostalCode).Length(5).When(x=>x.ZipPostalCode.StartsWith("9")).WithMessage("Please use a valid 5 Digit California Zip Code")
