Passport renewal guidelines
An expired passport is obvious grounds for a renewal but frequent travellers may not know that a lack of black pages also warrants a new document – even if it’s still in date.
If the booklet is filled up with stamps on each page, visitors must renew their passports to allow at least two entirely blank pages.
This rule applies in South Africa, Angola, Chad, and Kenya, though some countries require more.
Mozambique, Zambia, Madagascar and Botswana ask for three blank pages, while travellers headed for Namibia need six full pages free.
