Common MDAC mistakes and how to avoid them

The Malaysia Digital Arrival Card is a short form, and most people get it right first time. When something does go wrong, it is almost always one of a handful of small errors: a letter in the wrong place, a date one day off, an email that never arrives. None of them are hard to avoid once you know to look for them.

These are the mistakes we see most often when we check travellers' details, why each one matters and how to catch it before you submit.

Name mistakes

The name on your arrival card should match the name on your passport. Problems usually come from typing the name the way you normally write it rather than the way the passport shows it.

• Leaving out middle names. If your passport includes a middle name, include it on the card.
• Using a short or familiar name. "Bill" instead of "William", or an English name used socially but not printed in the passport.
• Adding titles. Mr, Mrs, Dr and similar do not belong in the name field.
• Mixing up name order. Some passports print the family name first. Keep the spelling exactly as printed and follow the form's prompts for which name goes where.
• Accents and special characters. If the form will not accept a character, use the spelling in the machine-readable lines at the bottom of the passport photo page, which uses plain letters.

A married name that is not yet in the passport is another trap. Use the name in the passport you are travelling on, even if your tickets were booked in a different name. If your flight booking and passport do not match, talk to your airline about that separately.

Passport number mistakes

A mistyped passport number is the most serious common error, because it is how the card is linked to you at the border. If the number is wrong, the officer may not find your card at all.

• O and 0, I and 1. Many passport numbers mix letters and digits. Read slowly, and compare with the machine-readable lines if you are unsure.
• An old passport. Browsers, travel apps and airline profiles often remember a previous passport. Type the number fresh from the passport you will carry.
• A family member's passport. When filling in cards for a family, it is easy to copy one child's number onto another child's card.
• Extra spaces. Type the number without spaces, even if it is printed in groups.

Date mistakes

Several dates appear on the form, and each one has its own trap.

Date of birth and passport expiry

Phones sometimes swap day and month, or the date picker scrolls to the wrong year. After entering a date, read it back as words: "the fourth of June, nineteen eighty-eight", not "four, six, eighty-eight".

Arrival date

The arrival date is the day you land or cross into Malaysia, in Malaysian time. On overnight or long-haul flights it is often the day after you leave home. Look at the arrival time on your booking, not the departure time.

Departure date

This should match your return or onward ticket. If you change your plans after submitting, the arrival date matters most, but keep your departure date realistic.

Travel detail mistakes

• The wrong flight number. On a journey with a connection, enter the flight that lands in Malaysia, not the first leg from home.
• The wrong last port of embarkation. This is the country you leave immediately before Malaysia. A traveller flying London to Doha to Kuala Lumpur should pick Qatar, not the United Kingdom.
• An incomplete address. Give the full address of your first night's stay, with the city, state and postcode, not just the hotel's name.
• The wrong mode of travel. Arriving by bus or car from Singapore or Thailand is "land", not "air", even if you flew into Singapore first.

Email mistakes

The confirmation and a PIN for checking your record are sent by email, so a mistyped address can leave you without proof of submission.

• Check for typos such as "gmial" or a missing dot.
• Use an inbox you can open on your phone while travelling, not a work address you cannot reach abroad.
• If nothing arrives within a few minutes, check the spam or junk folder before submitting again.
• For a family, decide which adult's email to use for everyone, so all the confirmations land in one place.

Timing mistakes

Trying too early

At the time of writing, the MDAC can only be submitted within the three days before your arrival. Trying a week early simply does not work, and some travellers then forget to come back. Set a reminder for three days before you land.

Leaving it too late

The opposite problem is more stressful. Filling in the form in a boarding queue, on airport Wi-Fi, with a low battery, is how typos happen. If the email is slow to arrive, you may also land without any proof of submission. Aim to finish the evening before you fly.

Using the wrong website

Search results for the MDAC include the Immigration Department's own site and many other sites, some of them independent private services like ours that charge for optional help. Paying a helper is a legitimate choice if you want someone to check your details for you, but no helper should look like a government site or suggest the card itself costs money. The card is free on the official MDAC website. Before you pay anyone, look for a clear statement that they are independent.

If you spot a mistake after submitting

Do not panic. The simplest fix, if you are still within the three-day window, is usually to submit a new card with the correct details and keep the new confirmation. The official site lets you check a registration, but its menu has no option to edit one. If you are unsure, ask the Immigration Department through the contact page on its website. If you only notice the mistake at the border, tell the officer plainly and follow their instructions.

Before you fly checklist

• Your name matches the passport, including middle names.
• The passport number has been checked character by character.
• The arrival date is the day you land in Malaysia, in Malaysian time.
• The flight number is the flight that lands in Malaysia.
• The confirmation email has arrived, and you have saved it.
• Every traveller in your group has their own correct card.
