Passport stamp
A passport stamp is an inked impression in a passport typically made by a rubber stamp upon entering or exiting a territory.
Passport stamps may occasionally take the form of stickers, such as entry stamps from Japan, South Korea, and Sri Lanka. Depending on nationality, a visitor may not receive a stamp at all (unless specifically requested), such as a European Union (EU) or EFTA citizen travelling to the Schengen Area, Albania, or North Macedonia. Foreign visitors to Iran (if your passport from visa-free country - a stamp is affixed) and North Korea also do not receive stamps in passports. Most countries issue exit stamps in addition to entry stamps. A few countries issue only entry stamps, including Canada, El Salvador, Ireland, New Zealand, Mexico, the United Kingdom and the United States.
Argentina, Australia, Cambodia, Cuba, Hong Kong, Israel, Macau, Jamaica, and Singapore do not stamp passports upon entry or exit. Some of these countries or regions issue landing slips instead. Australia does not issue any form of physical evidence of entry or exit as a matter of course at the primary line, but will provide entry and exit stamps upon request to a supervisor. Argentina and Singapore send digital entry receipts containing conditions of entry via email. The EU also plans to replace passport stamps with its Entry/Exit System by 2026.
Because there is no national authority, Antarctica does not have a passport stamp. However, the various research stations there may provide souvenir ones on request.
