Date mistakes
| Mistake | What to do |
|---|---|
| Trying to submit a week or more before the trip | Wait. The form only accepts an arrival date of today, tomorrow or the day after. |
| Giving the date of your flight from home as the departure date | Enter the date you leave Malaysia for another country. The official FAQ defines it this way. |
| Giving the day you leave home as the arrival date, after an overnight flight | The arrival date is the date you land in Malaysia. |
| Entering the date of birth month first | The form uses day, month, year (DD/MM/YYYY). |
Typing mistakes
| Mistake | What to do |
|---|---|
| A wrong character in the passport number | Read it from the passport itself. Several fields on the official form do not accept pasted text, so type slowly and check each character. |
| A name that differs from the passport | The form has one Name field. Enter the full name as it appears in the passport. |
| An email address that is rejected | Type the same address in both email fields. The form's check does not accept some characters, such as a plus sign (+). Use a plain address. |
| The country code typed into the mobile number | Choose the country code from the list. Enter the mobile number without it: digits only, up to 12. |
Address mistakes
- Writing "NA", "N/A", "NULL" or "NIL" as the address. The form rejects these.
- Leaving out the street. The form checks that the first address line is a real address of several words.
- Using special characters. The form asks for letters and numbers only.
- Guessing the postcode. Copy the 5-digit postcode from your booking, and choose the state before the city.
Rule mistakes
| Mistake | What to do |
|---|---|
| One MDAC for the whole family | Submit one MDAC for each traveler. See MDAC for families. |
| Skipping the MDAC because a long-term pass was approved | If you do not yet hold the physical pass, you need an MDAC. |
| Skipping the MDAC when changing from KLIA Terminal 1 to Terminal 2 | You need an MDAC for this transfer, and for flying on from another Malaysian airport. |
| Hong Kong or Macao passport holders choosing China as nationality | Choose Hong Kong or Macao, as the Malaysian consulate in Hong Kong advises. |
| Treating the MDAC as a visa | The MDAC is not a visa. Check Malaysia entry requirements. |
Using the wrong website
The official MDAC website is imigresen-online.imi.gov.my, and submitting there is free. Check the address before you enter passport details. See how to find the official MDAC website.
