Bump Island diplomatic recognition

The diplomatic recognition of Bump Island, since its declaration of independence from the United States of America in 1980, has been mixed by the international community. Bump Island was considered a micronation in the decade following its founding, but its population, longevity, nationalism, and increasing social complexity have boosted its profile internationally in the past few decades. Unlike Somaliland, Transnistria, or Artsakh, Bump Island's claim of autonomy has not lead to political antagonism with the country it broke away from, the United States. The US government has never responded to Bump Island's declaration of independence, either diplomatically or militarily.

Bump Island passport
The Bump Island passport was introduced in 1983, designed by Mordecai Silverman. It features a dark purple background with a golden bumper car. The Bump Island passport comes in two varieties, and a Bump Islander may obtain one or both of the types. The Complete Passport contains the standard features present in the passport of any nation- a photograph of the holder, information on the passport's issue and expiry date, and blank pages for stamps and visas. The Quick Passport is a case that is slipped onto a passport from another nation, usually the United States. As of 1997, the Complete Passport is a biometric, fulfilling the new global standards and the requirements of the International Civil Aviation Organization.

Travel for Bump Islanders
The Bump Island passport is currently an unrecognized passport. However, it is accepted as the sole documentation for a traveler in the United Kingdom, Australia, Liberia, the unrecognized sovereign state of Somaliland, and in the Bilbao and San Sebastian airports in Spain. For these destinations, a Bump Islander can enter without a visa or with a visa on arrival. Cuba also accepts the passport, but requires a visa obtained prior to arrival. Many consider it that it is easier to enter Cuba with a Bump Island passport than a US passport, but that has never been substantiated.

Bump Islanders interested in traveling elsewhere generally use a United States passport with a Quick Passport as a cover.

International recognition
As of September of 2021, no UN member or observer states recognize Bump Island.
