Passport validity

Passport validity is the length of time a passport can be used to travel to another country, or be used as a valid form of identification within or outside the issuing country before its date of expiration.

Adult passports
There is an increasing trend for adult passports to be valid for ten years, such as a United Kingdom passport, United States Passport, New Zealand Passport (after 30 November 2015) or Australian passport. A five year period of validity is also common (as used to be the situation for a Papua New Guinean passport or currently for an Indonesian passport. Some countries issue adult passports for periods between five and ten years, such as the Cuban passport, which is valid for six years.

Optional validity period
Some countries allow adult applicants to choose a passport validity, usually 5 or 10 years, at a varying price scale, e.g. costing more for 10 years than 5 years. These countries include Canada, Hungary, Japan, Mexico (1, 3, 6, or 10), Pakistan, Russia, and South Korea.

Child and young adult passports
Most countries issue passports for children and young adults for five years, under passport issuing protocols a child or young adult passport is defined as being under 16 years for a United States Passport, under 19 years for a Japanese Passport, under 21 years for a Croatian passport, under 24 years for a German passport or under 30 years as is the case with a Spanish passport.

Infant passports
Because children change rapidly in appearance from infancy to age five, some countries issue infant passports for two years, such as the Austrian passport, or for one year in the case of the Republic of Korea passport.

Senior passports
Some countries issue passports with longer validity period to their senior citizens, for example Spanish passports issued to citizens over 70 never expire.

Validity on arrival
Many countries require passports to have a remaining validity of six months or more on the date of arrival. These include Malaysia, Singapore, Hong Kong, Taiwan, Japan, but some countries like Schengen Area is 9 months.
