All 85 MPs present voted 'for' the proposal.
Everyone with a personal code will be able to change it free of cost to the new format - on a voluntary basis - from July 1, 2017.
As of now a Latvian personal code consists of eleven digits. The first six digits have the person's date of birth, while the seventh number signifies the century - 0 for the 19th century, 1 for the 20th century and 2 for the 21st century. The new ID numbers will have the same number of digits as in the personal code.
Authors of the amendments said that, according to good personal data protection practices, persons should be made identifiable via means that don't give away the person's date of birth.
