Usually that means that the Zip code is not in the SASHELP.ZIPCODE data set. It may be that yours is out of date. Instructions on updating it are here:

https://support.sas.com/techsup/notes/v8/19/861.html

or that those Zip codes do not exist

When I use the US Post office Zip code to identify the city from zip at https://tools.usps.com/zip-code-lookup.htm?citybyzipcode

The 76025 and 76100 return as invalid Zip codes.
