According to documents: is the employment record book electronic or paper? Service record or military ID?

In Russia, since 2020, the employment record book can be either paper or electronic. The employee and employer can choose the electronic format, which is stored electronically in the Pension Fund.

The registration certificate is a document confirming registration for military service at the military commissariat for male citizens of draft age.

The military ID is the main document certifying military service or registration for military service, issued after conscription or service.

Thus, the employment record book can be in electronic or paper form, and the registration certificate and military ID are different documents related to military registration and service.
