Canada does unfortunately. It's called a Social Insurance Number (SIN) or Numéro d'assurance sociale (NAS) but other than the name, it is mostly the same. And Canada is on the list of the countries suffering from the breach. This should be interesting.

Indeed. I wanted to see if I was on the list, but the site they set up to check looked pretty sketchy.

They've clearly demonstrated I shouldn't trust them with my SIN (not that I ever willingly did in the first place!) so why should I enter it again? Into a different domain, no less?!

Which countries do you mean? How do they manage their credit scores?

Using much more nebulous and unreliable forms of PII as identifiers, in my experience, which leads to situations where you could query someone's report if you know their name and street address.

Well that sounds just as bad...
