can you explain what type of headaches your would expect? in Denmark we have had the issue that some companies issues loans solely based on social security numbers. however, the root issue is that lenders did not verify identity, and I am quite sure that companies malpracticing like this are liable themselves. mean while, AFAIK, in Sweden social security numbers are public info - that it probably what we should aim for.
