I have a list of zip codes, some of which have the 4 digit extension and some that don't. There are two different zip code types listed under special, but neither of them work. The 5 digit only, sorts as follows:
38123
49436
90210
49436-1234 - Notice this is out of place
The extension one adds extra numbers to the ones missing the extensions.
Any idea on how to get around this?
