After making a post about being able to see an account number for any domain registered with NSI, I got a pretty quick reply from David Morse. After I showed (walked him through) how I could see them, It got his attention and he said he would get back to me.

David replied with:

"What my research has shown is that Account Number is not able to be used in place of a User ID.  At one point, this was true, many years ago and the instructions in the pop up reflect that.  We currently are taking steps to change the pop up text.Account Number is an identifier pointing a customer service rep to work on the correct account. 

However, I agree with you, that even if it is not part of the Username / Password pair, we should guard this information more closer.  This one needs to be vetted a bit more, but progress is being made."

I am very happy to see a quick reaction to this and thank David for taking action. Below is currently what the info did look like:

You can click the picture above to show a better detailed graphic. I have blurred out the info, but the blurred out info was. Account Number, Business Name, Contact Name. Then lower show two different names for contact of the account as well as the NIC Code for each.
