Tax By CountryStateZip

Using V3.6

We are in Canada and have created a tax category for Canada.  We created all the provinces in TAX PROVIDERS and entered "*" for the zip code field.  I thought this would capture all the postal codes but it doesn't.

The correct tax is only displaying when I enter "*" in Zip Code field.  What should I be entering in ZIP CODE box if I want to capture all the zip codes for each province?

Thanks in advance for any assistance.

Just leave it empty.

Thanks for replying.  I can't leave it blank.  It defaults to the '*'.  Do you know if there is something else i need to do?

I can't remove the "*" in the zip code field in Tax Providers.  Anyone else get this to work by state/province tax?
