World Passports, IDs, etc.
Founded by World Citizen #1 Garry Davis in 1954, the World Service Authority in Washington DC has issued over 4 million World Passports, Birth Certificates, Marriage Licenses and IDs along with other human rights tools mandated by the Universal Declaration of Human Rights.
The World Passport is not an assured travel document. Not every country recognizes it (just like any passport) It is a human rights tool.
Be familiar with your rights before using it to travel (especially article 13.2 of the Declaration of Human Rights)
