After a brief period of grace, the Malaysia Digital Arrival Card (MDAC) is now mandatory for passport holders of most countries.
To be completed within three days of travel for every visit to
Malaysia, the MDAC requires foreign travellers to provide details such
as their name, passport information, nationality, date of arrival, date
of departure, mode of transport (air, land, or sea), and the last port
of embarkation. Failing to adhere to this may result in refusal of
entry.
Arrivals from Singapore are among those not required to complete the digital declaration.
Others on the exemption list include holders of diplomatic and
official passports, Malaysian permanent residents and long-term pass
holders, as well as frequent and border pass holders from Thailand,
Indonesia and Brunei.
