DDOT has opened up its system for ordering 2015 Visitor Parking Passes. Go here and select “Pre-register for a 2015 VPP” at the bottom of the page, then follow the prompts. If you have a problem with your address, call DDOT at 202-671-2700 and talk with a staff person.
The addresses in the system were cobbled together from several different DDOT databases and don’t seem to have been “synchronized.” It is inevitable that some addresses people enter and the form in which they enter them will generate various types of error messages. When I did my request, I simply entered my address as “# Street name Type SE” and my address popped right up. Others have been told to enter just the # and Street name without any caps or punctuation. This is the minimalist method of querying databases. If you want to fiddle with the system, go right ahead. But, my suggestion is to simply call the DDOT number and let the staff person figure it out for you.
The website also has a link to complete information on the VPP system. Eligibility is explained in full there or you can go to my VPPs Change. Somewhat. article and read point #5.
