Common MDAC Mistakes and How to Avoid Them

Many travelers submit the Malaysia Digital Arrival Card (MDAC) before each trip. Errors on the form can delay or complicate your submission. This guide covers the most common MDAC mistakes and how to avoid them.

If you are ready to apply, you can submit your MDAC application here, an MDAC application assistance service. First, read this guide to avoid the common errors below.

Why MDAC Mistakes Matter

The Malaysia Digital Arrival Card is a pre-arrival declaration required for most foreign travelers entering Malaysia. Information that is wrong or does not match your passport and travel documents can mean:

• Having to submit a new MDAC
• Questions about information that does not match your documents
• Avoidable stress close to departure

Many travelers only notice a mistake after they have submitted. This guide helps you catch it before you submit. See do you need an MDAC? for who must submit one.

Mistake #1: Incorrect or Mismatched Name

The Problem

Your name in the MDAC should match your passport exactly.

Common name-matching errors:

• Typing a nickname instead of your legal name ("John" when the passport shows "Jonathan")
• Omitting middle names that appear in the passport
• Reversing first and last names, especially where name order differs between cultures
• Adding or removing spaces ("Mary Jane" vs "MaryJane")
• Dropping accents or diacritics ("José" vs "Jose")
• Abbreviations ("Wm" instead of "William")

How to Avoid It

1. Keep your passport open while filling out the MDAC
2. Read your name exactly as it appears on the data page
3. Check spaces, hyphens and special characters
4. Compare the name letter by letter with the passport before submitting

What If You've Made This Mistake?

A submitted MDAC generally cannot be edited. If a detail is wrong, check the information carefully and complete a new application with the corrected details, as described on our MDAC page.

Mistake #2: Passport Number Errors

The Problem

A single wrong character in the passport number means the MDAC does not match your passport.

Common passport number mistakes:

• Transposed digits (typing "56" instead of "65")
• Mistaking letters for numbers (the letter "O" and the number "0", or the letter "I" and the number "1")
• Missing characters such as leading zeros
• Using an old passport number after renewing your passport

How to Avoid It

1. Copy the number from the data page of the passport you will travel with
2. Read each character aloud as you type it
3. Zoom in if the number is hard to read
4. Ask someone else to check the number you entered

What If You've Made This Mistake?

Submit a corrected MDAC as soon as you notice, and keep your passport number to hand for the correction.

Mistake #3: Wrong or Missing Arrival Date

The Problem

Your MDAC arrival date should match your actual travel plan.

Common arrival date mistakes:

• Entering your departure date from home instead of your arrival date in Malaysia
• Entering the wrong month or year
• Date format confusion (DD/MM/YYYY vs MM/DD/YYYY)
• Off-by-one errors, including overnight flights that land the next day
• Not allowing for time zone differences (Malaysia is UTC+8)
• Not allowing for changed travel plans, such as a rebooked flight

Understanding the Timing Rule

The MDAC can be submitted within the three days before your arrival in Malaysia. Check that your arrival date falls inside that window when you submit, and that the date you enter matches your actual plans.

How to Avoid It

1. Confirm the date you will physically enter Malaysia, in Malaysia time
2. Check your flight itinerary before entering the date
3. Use the date format shown on the form
4. Double-check the date before final submission

What If You've Made This Mistake?

If you notice before travelling, submit a corrected MDAC. If your travel plans change after you submit, check whether a new submission with the new date is needed.

Tip: The MDAC is separate from any visa. See our Malaysia visa processing time guide to plan your visa timeline.

Mistake #4: Incomplete or Incorrect Accommodation Information

The Problem

The MDAC asks for your accommodation in Malaysia. Incomplete or incorrect details are a common error.

Common accommodation errors:

• Misspelled accommodation name
• Incomplete address (name only, with no street address or city)
• Wrong city or state
• Postcode typos
• Providing only the country ("Malaysia") without city details
• A booking that has since changed or been cancelled

How to Avoid It

1. Have your booking confirmation open
2. Copy the exact name and the full address from your reservation
3. Include the street address, city, postcode and state
4. Check the address on a map before entering it
5. For private rentals or a friend's home, confirm the full address details

What If You've Made This Mistake?

If your accommodation changes or you find a mistake, check the details and submit a corrected MDAC if needed.

Mistake #5: Wrong Departure Date

The Problem

Your departure date should be realistic and after your arrival date. Common mistakes:

• Departure date before the arrival date
• Using the wrong year or month
• An unrealistic departure date that does not match your return booking
• Ignoring visa validity: if you are travelling on a Malaysia eVisa, check your permitted stay
• Off-by-one errors on the last day in Malaysia

How to Avoid It

1. Confirm your return flight or transport date before filling in the form
2. Enter the date you will actually leave Malaysia
3. Make sure it is after your arrival date
4. Check it against your permitted length of stay

Mistake #6: Incomplete Flight or Transport Information

The Problem

The MDAC asks about how you are arriving. Errors here are common:

• Wrong flight number, copied from a different leg of your journey
• Incomplete flight number, missing the airline code (for example "450" instead of "MH450")
• Using a connecting flight instead of the flight that arrives in Malaysia (if flying Sydney, Singapore, Kuala Lumpur, use the flight that lands in Kuala Lumpur)
• Misspelled airline or vessel name
• Leaving the field blank or using a placeholder when you do not know the flight yet
• Mixing up outbound and return flights

How to Avoid It

1. Identify the flight that actually arrives in Malaysia
2. Include the airline code and the full number (for example "MH17", not just "17")
3. For land or sea entry, use the transport operator or vessel name from your booking
4. Check your booking confirmation or boarding pass
5. If you have not booked yet, confirm your travel before submitting

See who needs a Malaysian visa for general entry requirements, including if you plan to enter by land.

Mistake #7: Missing or Invalid Email Address

The Problem

Your email address is where your confirmation is sent. A typo means you may not receive it.

Common email errors:

• Typos in the domain ("gmai.com" instead of "gmail.com", or ".con" instead of ".com")
• A missing "@" symbol
• An address you no longer use or cannot access
• Spaces in the address

How to Avoid It

1. Use an email address you check regularly
2. Type it slowly and read it back character by character
3. Check your inbox and spam folder for the confirmation after submitting

What If You've Made This Mistake?

If you did not receive a confirmation, check your spam folder first, then check the email address you entered. Keep the reference number shown on screen if you have one.

Mistake #8: Mismatched Passport and Personal Information

The Problem

Personal details in the MDAC should be consistent with your passport.

Common inconsistencies:

• Name variations ("Robert" in the passport, "Bob" in the MDAC)
• Date of birth typos, especially the year
• Gender or sex entered differently from the passport
• Wrong nationality, especially for dual nationals (use the nationality of the passport you will travel with)
• Passport issue or expiry dates entered incorrectly

How to Avoid It

1. Have your passport open as you fill in the entire form
2. Copy details from the passport, not from memory
3. Double-check dates, especially date of birth and passport expiry
4. Review the whole personal information section before submitting

Mistake #9: Submitting the MDAC Too Late

The Problem

The MDAC is submitted close to your arrival, so leaving it until the last moment can cause avoidable stress.

Late submission issues:

• Waiting until the day of arrival, when you may be rushed or lose connectivity
• Submitting from a place with poor internet
• Submitting while boarding or in transit

How to Avoid It

1. Submit within the three days before your arrival, but not at the last minute
2. Check that you have received a confirmation before you leave for the airport
3. Save the confirmation email or a screenshot on your phone
4. Write down the reference number as a backup

Mistake #10: Incorrect Last Port of Embarkation

The Problem

For air travelers, the last port of embarkation is the airport you departed from immediately before arriving in Malaysia, not necessarily your home country.

Common errors:

• Entering your home country instead of your last airport
• Entering your final destination instead of where you flew from
• Confusion on multi-leg journeys (Sydney, Singapore, Kuala Lumpur: the last port is Singapore, not Sydney)
• Typos in the airport name or code

Example

You are travelling London, Dubai, Kuala Lumpur.

• Wrong: entering London as the last port of embarkation
• Correct: entering Dubai, the airport you departed from immediately before arriving in Malaysia

How to Avoid It

1. Identify your last flight before Malaysia
2. Check the airport name and code against your itinerary
3. On a direct flight, the last port is your origin airport; on a connecting flight, it is your connection airport

Quick Reference Checklist
