SGAC or MDAC Mistake: How to Update Arrival Card Details Before Travel

Mistakes on digital arrival cards usually happen after submission: a wrong passport expiry date, a changed flight number, or a typo in the passport number. The fix depends on the country and the official system.

TL;DR: For Singapore SG Arrival Card, ICA provides an official "Update a Submission" route while the record is still valid. For Malaysia MDAC, return to the official MDAC portal and follow the current option shown there; if you cannot correct the record, contact Malaysia Immigration or submit again only if the official system allows it.

Direct Answer: SGAC vs MDAC Correction

Singapore SGAC: Use "Update a Submission"

Singapore ICA's public help pages state that you can update an SG Arrival Card submission before the record expires. The practical workflow is:

1. Open the official SG Arrival Card e-Service.
2. Choose the option to update a submitted record.
3. Retrieve the submission using the required details.
4. Correct passport, flight, accommodation, or arrival information.
5. Save the new confirmation and keep the latest barcode or receipt.

Do not use paid third-party sites for SGAC. The official submission is free.

Malaysia MDAC: Check the Official Portal First

Malaysia requires many foreign visitors to submit MDAC before arrival. If you find an error, go back to the official MDAC portal and check the current available actions.

Because public MDAC guidance can change, avoid relying on screenshots from travel forums. If the portal does not show a clear edit option, use Malaysia Immigration's official contact or help channel before making assumptions.

Do not create multiple conflicting submissions unless the official MDAC system allows or instructs it. Keep the latest confirmation that matches your passport and trip.

What Details Matter Most

Check these fields first:

• Passport number and nationality.
• Passport expiry date.
• Full name and date of birth.
• Flight number, arrival date, and port of entry.
• Accommodation address or contact details.

If your flight changes after submission, update the record where the official system supports it. For same-day travel, keep screenshots of the corrected confirmation.

How eVisaFlow Helps Before Submission

eVisaFlow Chrome extension can help reduce avoidable errors by entering saved passport and trip information for SGAC, MDAC, and other supported digital arrival cards. You still review the official page before submitting.
