Having the same issue. I'm trying to find a commonality in all of us that are having this issue. I noticed this problem after I had suspicious activity on my credit card. I contact my credit card company and told them that I had a purchase from the google store for $100.00 that I did not authorize. The credit card company took care of it and I didn't have to pay. HOWEVER, I'm wondering if GooglePlay didn't like that I questioned a purchase and froze my account.
So- has everyone here had some sort of authorization issue with their account before they started seeing this code? I'm wondering if it's some type of "LOCKED ACCOUNT" code?
