Are the data by any chance multinational and you are getting other system postal codes? If so you may want to modifiy Haikuo's suggestion to output the data to two different datasets.

You can also use the sashelp.zipcode table to determine if any particular ZIP code is valid.  That data are updated every few months, so you may need to download the current one from sas.com.
