Passport number[edit]

The passport number is the serial number that uniquely identifies a passport. The passport number changes every time a person is issued a new passport, with the previous passport number noted in an endorsement on the last page of the new passport.

The passport number is alphanumeric, with a letter followed by an eight-digit number, e.g. A00000000. The letter prefix depends on the residency status of the bearer: "A" for Peninsular Malaysia and Labuan, "H" for Sabah and "K" for Sarawak. From 1964 to 1965, when Singapore was a part of Malaysia, Singapore citizens were issued Malaysian passports with the prefix "E".^[10]
