Hi, Pete:
I am a little confusing about your purpose. Are you trying to create a windows-base application and it can search your EXCEL table by ZIPcode, is it correct? :) In this case, you can read the following article, it has some information about "Extract Information from Excel Sheet with DAO". http://support.microsoft.com/default...NoWebContent=1. If you are using VB and ADODB database engineer, the only thing you need is changing the DAO to ADODB.

Good Luck.
