In the US, consumers can freeze their credit worthiness records and receive a code. When the records are frozen, the only orgs that can access the records are those already doing business with the consumer. If a consumer wants to open up a new account, they share the code with the prospective creditor who uses it to see the credit report.

So the question is, how are access controls on credit histories done in various EU nations? Do any use unlock codes like the US, or is it all trust based?
