I was asked today if there a function in SAS or some way to get to the ZIP +4 if address/zip.

If I already have the Zip+4, I think I can use the Geo-coding to put the address on the map, but no conversion to ZIP+4 from Address/Zip.  Did I miss anything?

I've never tried it, but could you use street geocoding?  Take a look at:

SAS/GRAPH(R) 9.2: Reference, Second Edition

Recently I have done some Proc Geocode on street level, this paper will pretty much answer all of your questions:
