Common Mistakes Travelers Make When Submitting MDAC (And How to Avoid Them)
Common Mistakes Travelers Make When Submitting MDAC. The Malaysia Digital Arrival Card (MDAC) is now a mandatory requirement for most international visitors entering Malaysia. While the online form is relatively easy to fill out, there are still many mistakes travelers make when submitting MDAC that can lead to delays, confusion at immigration, or even denial of entry.
1. Submitting Outside the Allowed Timeframe
Mistake: Many travelers submit the MDAC too early (weeks in advance) or too late (just before landing).
What You Should Know:
You can only submit the MDAC within 3 days before your arrival date. Submissions outside this window may be invalid.
How to Avoid It:
- Set a reminder to fill out the MDAC 72 to 24 hours before your flight.
- If your travel date changes, resubmit the form during the new valid window.
2. Entering Incorrect or Incomplete Information
Mistake: Common errors include typos in passport numbers, wrong travel dates, or missing accommodation details.
Why It Matters:
Incorrect details may raise red flags during immigration checks and delay your entry.
How to Avoid It:
- Double-check all information before submitting.
- Use official travel documents to copy exact passport numbers, dates, and full hotel addresses.
3. Uploading Poor-Quality Documents
Mistake: While the MDAC doesn’t always ask for documents, some users still upload blurry or cropped passport photos when requested.
How to Avoid It:
- Only upload clear, full-color images of your passport bio-page if prompted.
- Make sure the image is well-lit, in focus, and shows all edges.
4. Using the Wrong Browser or Device
Mistake: Travelers often face technical issues using unsupported browsers or unstable internet connections.
Common Issues:
- Pages freezing
- Submission errors
- Incomplete processing
How to Avoid It:
- Use a reliable desktop browser like Chrome or Firefox.
- Avoid using public Wi-Fi or outdated mobile browsers.
- Clear cache or try incognito mode if the site isn’t loading properly.
5. Submitting on Fake or Scam Websites
Mistake: Some users unknowingly submit their details to third-party sites pretending to be the official MDAC portal. These may charge money or steal data.
How to Avoid It:
- The MDAC form is 100% free. You should never be asked for payment.
- Always verify you’re on the official Malaysian Immigration website before filling in personal data.
- Never submit passport or credit card details on suspicious websites.
6. Thinking You Can’t Resubmit After a Mistake
Mistake: Some travelers think that once the form is submitted, it can’t be changed—even if there’s an error.
The Truth:
You can simply resubmit the MDAC with the corrected information. The latest version will be considered valid at immigration.
How to Avoid It:
- Don’t panic over typos. Just go back, fill out a new form, and submit again.
- Keep a copy of your updated confirmation and discard the old one.
7. Losing the Confirmation Email or PIN
Mistake: Some users forget to save the MDAC confirmation email or delete it before arrival.
Why It’s Important:
- You’ll need to show the confirmation email or PIN at the immigration checkpoint or auto-gate.
How to Avoid It:
- Use a working email address and double-check for typos.
- Check your spam/junk folder if you don’t see the email.
- Save the PIN number and download a copy of the confirmation in advance.
