I did the credit freeze for Equifax, TransUnion, and Experian. Experian was by far the most convoluted process. In fact I couldn't get Experians's online freeze to take. They asked me to upload scans of my driver's license and a utility bill. But once I tried to upload them it rejected them because they were not tiff format (they never specified what format was expected). I did it again in tiff and it rejected it because it was in color, not b&w (again no specification beforehand). I redid the scans a third time and it continued to insist they were in color. At this point I called their automated phone line and completed the freeze that way. But with my wife's info I couldn't get Experian to accept an online request, or the automated phone request. So we are having to mail in the documentation via snail mail.
