Thread: How to change Shipping Zones from 3 digit zip code to 5 digit.

We are creating a shopping cart for a small geographic area where we do local delivery with our own trucks. Internally we have already broken up these cities into zones. The problem with the built in 3 digit method is all of these cities share the first 3 digits despite being on completely different delivery routes. I need to change this to read all 5 digits.

In the appconfig I have changed the zipcodeprefixlength to 5. This is now throwing server errors so there must be some place in the code I need to change it. Any suggestions?

Here is the error:

Server Error in '/AspDotNetStorefrontML9' Application.

The other error that is a little more helpful and points to the shipping.cs page is this.

I resolved the issue. Turns out I had zone ranges that overlapped some of the 5 digit zones I created which was causing the issue. After deleting the junk zones it's working correctly.
