I'm considering having points transferred into my account. I was told that the other person will need my account number and name. Could be done without them having my full account number. With my name and last 4 account numbers, they could deposit into my account. If there's any confusion, member services will request an email or fax with complete member number and signature. The one transferring points has to initiate the transfer of points though. That's how I remember it being explained to me. Otherwise, I've been given a person's whole member number to transfer into their account, and I've given out my whole member number to someone I was getting points from. I didn't keep records of their account number. As long as they don't have the last 4 digits of my ss#, they're out of luck if they want to access my account. Plus, I never have enough points in there!
