In addition to what other siblings already said, in Australia we have a scoring system to prove your identity (called "100 point identification") and depending on the score needed, drivers licence can get you there so it's used very often. This system is for Government entities but private companies often take inspiration from it

This is the SA version since GP is from South Australia, all other states have the same thing too https://www.police.sa.gov.au/services-and-events/100-point-i...

An interesting thing is that "100 point ID" applies to physical documents, but somehow it's been conflated with the number on the document being equivalent. One is obviously more easily copied than the other, and scales better for fraudulent use.

It's much cheaper to make a computer check the number than pay the post office to sight and verify ID docs.
