Zimbabweans are required to apply for National Registration at the age of 16. Zimbabwean citizens are issued with a plastic card which contains a photograph and their particulars onto it. Before the introduction of the plastic card, the Zimbabwean ID card used to be printed on anodised aluminium. Along with Driving Licences, the National Registration Card (including the old metal type) is universally accepted as proof of identity in Zimbabwe. Zimbabweans are required by law to carry identification on them at all times and visitors to Zimbabwe are expected to carry their passport with them at all times.
