Databases Touch Our Lives

I recently received a fundraising letter from my law school. Nothing unusual there. Letters addressed to me at my current address usually reach me. Particularly if they’re enclosed in an envelope addressed to me at my current address.

Now the donation card, though, that was another matter. That one was addressed to me at my address in Redmond, Washington. I haven’t lived there in eight years. I moved out of there nearly a year and a half before I even applied to law school. I’ve had six distinct mailing addresses in between my Redmond one and my current one. I don’t believe I’ve ever listed it in any correspondence with my law school.

Where did they get the idea that this was my address? How did they decide this was where I lived for purposes of the donation card but not for the envelope or the letter? What frightful database decided to play this little prank on me, and why?
