The MDAC registration acknowledgement is a confirmation document containing a QR code and a printed slip, issued after you complete the Malaysia Digital Arrival Card online. It is linked to the passport number you entered during submission. At Malaysian immigration, present both the QR code and your passport; the officer scans the QR to verify your registration in the MyNIISe system before stamping your entry.
This information is provided for guidance only and may change. Always verify current requirements with the Malaysian Immigration Department before travel.
What You Receive After Submitting Your MDAC
The Malaysia Digital Arrival Card MDAC registration acknowledgement is the confirmation you receive after completing the MDAC online. The Malaysia Digital Arrival Card (Kad Ketibaan Digital Malaysia) has been mandatory for all foreign travellers entering Malaysia since 1 January 2024 (source: kln.gov.my). Upon successful submission via the MDAC portal, the system generates two outputs: a QR code and an acknowledgement slip.
The QR code encodes a registration token linked to your passport record in Malaysia’s MyNIISe (Malaysia National Integrated Immigration System). The acknowledgement slip displays these fields:
- Full name
- Passport number
- Travel dates
- Flight number
- Port of entry
- Submission timestamp
- Confirmation number
The MDAC registration acknowledgement arrives as an automated confirmation email from the Malaysian Immigration Department, sent as a PDF attachment to the address you provided during submission. Save the PDF to present (digital or printed) with your passport at immigration. For more details, see our step-by-step MDAC application process.
How the MDAC Links to Your Passport
The MDAC acknowledgement links to the passport number entered during submission. Malaysia’s immigration database, MyNIISe (Malaysia National Integrated Immigration System), uses that passport number as the primary key identifier to store and retrieve your arrival record.
The QR code on the acknowledgement slip encodes a token that resolves to the same passport record when scanned at the immigration counter. The officer scans the QR code, the system pulls up your registered details, and the officer visually confirms that the name and passport number on the slip match your physical passport.
A mismatch can delay or prevent entry. Verify that the slip’s full name, passport number, and expiry date match your physical passport exactly. If incorrect, submit a new MDAC as edits are not supported after generation.
What to Show at Immigration
At the immigration counter, present your MDAC acknowledgement alongside your passport; the officer scans the QR code or checks the slip details before approving entry.
The MDAC registration acknowledgement can be displayed on your phone screen as digital display is accepted at Malaysian immigration counters. Carry a printed backup as a precaution: airport Wi-Fi at KLIA/KLIA2 is unreliable, phone battery may be low after a 12+ hour flight from Heathrow, and data roaming adds cost. Download the PDF to offline storage and screenshot the QR code before departure.

Retrieving a Lost or Missing MDAC Acknowledgement
If lost, check your spam folder, then use the SSPI (Semakan Status Perjalanan / Immigration Control Status Checking) tool on imi.gov.my or contact the helpdesk at [email protected] / phone 03-88801555 (Bilik Gerakan JIM, 8:30 AM to 11:00 PM daily, including weekends and public holidays). If travel is imminent, submit a new MDAC before departure. On a recent trip, a traveller forgot to save the PDF and used the SSPI tool at the airport; it worked but took 10 minutes. Save the confirmation email immediately upon receipt.
When to Submit, How Long It’s Valid, and Who Needs an MDAC
The Malaysia Digital Arrival Card registration must be submitted within 3 days (72 hours) before your scheduled arrival (source: kln.gov.my). For example, flying from London Heathrow on 20 September, arriving KLIA on 21 September means you can submit from 18 September onwards.
The acknowledgement is valid for single entry only, tied to the specific arrival date declared in the form, and does not carry over to future trips. If travel dates change, submit a new MDAC.
All foreign travellers entering Malaysia must complete an MDAC, regardless of visa-free status. UK passport holders are not exempt. MDAC is not a visa but a digital arrival declaration. Exemptions apply to Singapore citizens, diplomatic and official passport holders, Malaysian permanent residents, and transit passengers who do not clear immigration.
Every traveller, including infants and children, requires a separate MDAC submission completed using the child’s own passport details. If you are flying into Kuala Lumpur, check our KLIA airport guide.
FAQ: MDAC Registration Acknowledgement
