The CSV files from MLS also contain the membership IDs, which is a permanent identification. That is what you can use and never change. The internal ID value seems fairly stable, but I only use it to match up the HT/VT and Organization records with the Membership records. I have defined an auxiliary file that I use for my program. This file contains the membership ID along with any other information I want to keep (like cell phones and e-mail for each member) By comparing the auxiliary file with the import, I can tell who is new and who is no longer on the records.
