  • C: the century sign, which shows the user’s century of birth.

Unique identification number

Online services typically use the unique identification number. Unlike the personal identification code, it doesn’t reveal personal information such as the user’s date of birth. The first 8 characters are random digits, and the last character is a check character.

Level of assurance values

The level of assurance shows how confident you can be that users are who they claim to be. It follows the eIDAS levels of assurance in the European Digital Identity Framework. To learn more, see eIDAS Levels of Assurance.
