This information is listed on the page link that MentalGiant listed above, but I thought I would just throw it out here for anyone to read who might want it.
" How do you get a copy of your report?
Contact DAC Services at (800) 381-0645 and request information on obtaining your report. You'll probably need to request the report in writing due to security concerns and you'll want to include a copy of your driver's license and social security card. The address for DAC/USIS is:
4500 S. 129th East Avenue
Suite 200
Tulsa, OK 74134-5885
Once you receive the report, check it carefully for errors and negative entries. Chances are good that the information will be correct and positive but if it isn't, it's time to get hopping. "
