The passport issued by a country with no country
One of the rarest passports is issued by the Sovereign Military Order of Malta, a centuries-old Catholic institution that runs humanitarian and medical programs and maintains diplomatic relations with many countries. The Order is not a nation-state with a territory of its own, but it has a recognized international role—and issues diplomatic passports to a small circle of officials serving in that role.
It is a job credential, not a membership perk
The passport is generally reserved for the Order’s senior leadership and diplomats, rather than its members or the people it helps. That distinction explains its scarcity: holding it depends on occupying a particular official post, not simply belonging to the organization. The Order’s diplomatic passports are issued in limited numbers; estimates commonly put the total at roughly 500, though the number can change as appointments and documents expire.
What the passport does—and does not do
A diplomatic passport can identify its holder as an official representative and support travel for diplomatic work. It does not make the holder a citizen of a country called Malta: the modern Republic of Malta is a separate state, and the Order has no ordinary population or national territory. Nor does the document automatically guarantee entry or diplomatic privileges everywhere; those depend on the destination and the holder’s official status.
Its rarity comes from that narrow purpose. It is less a travel document for a public than a credential carried by a small group representing an unusual institution on the international stage.
