Joining a CSV file to geodatabase

[ChaseBergklint1]

Hi, I have two files that I  need to join. I have a geodatabase file that has all the zip codes, Name of the state, the Object ID and other information.. I also have a CSV file that has the alumni for my school and their zip code. I am trying to join the two based on the Alumni Zip code. When I do that, not all the zip codes match.Can someone show me how to do that please? I have the documents posted here if you want to view them.

Thanks,
Chase

So, are you trying to join to one of the shapefiles?  Or the .lyr file?

I have the shapefiles joined now I am in the process of trying to get the whole map together.
