'proven ID numbers' is idiomatic?

Chinese English media says:

An Internet booking system for train tickets will be introduced for the high-speed Shanghai-Beijing route when it opens in June. Meanwhile a real-name ticket purchasing system, which requires proven ID numbers will be expanded to all bullet train services.

I want to know if the term 'proven ID numbers ' is idiomatic English. Thank you very much.

Thank you. I consulted my teacher, who suggested the term 'verifiable IDs' in place of 'proven ID numbers '. Does it work better?
