I'm not sure on the specifics, but the entire point of Verify as a technology was to ensure there was no government database about people. The UK has very distributed technology for government services, there is no one big database, and people have pushed back hard on this many times over the years so the government is pretty paranoid about doing it. Each agency holds only the data they need for the time they need it. There are no national ID cards. And in the case of Verify, the verification was purposefully outsourced to private companies that already had this data due to their business (e.g. your bank, PayPal, Amazon who have a trustworthy address history, Experian, and so on).
