How do I get an IRD number for my baby?
You can apply for your baby's IRD number when you register the birth online through SmartStart. Applying is free. If you also apply for Best Start, Inland Revenue will give your baby an IRD number while it processes your application. The number stays the same for life, so keep it safe.
