When you start your application, you will be given a form to fill out. Check the top of the form to see whether it says Borang B or Borang D. Ensure that you are given Borang B, as your child was born before the amendment is gazetted.
If you have already applied and submitted your application in Malaysia, you should have received an application receipt, as shown in the image below, with Borang B clearly indicated. If your receipt says Borang D, it is no longer valid, and you will need to reapply using Borang B.
However, if you applied overseas, you may not have received an application receipt to verify the details. In this case, you will need to confirm with JPN. Write an email to them (upkbwn@jpn.gov.my), providing your full name, IC number, your child’s name, and request confirmation of the article under which your application was submitted. Additionally, ask for your application number so you can check the status online.
