What a Centrelink Customer Reference Number (CRN) is

Your Centrelink Customer Reference Number (CRN) is a number we use to identify you. It has 9 numbers and a letter at the end, like this: 123 456 789A.

Why you need a CRN

You need a CRN to get our payments and services.

You use your CRN to:

We use your CRN to identify you and access the information you’ve given us.  

We may also use your CRN to link your information to your family.

How you can get a CRN

If you get a payment from us, you'll have a CRN.

You'll also have a CRN if your parents got Family Tax Benefit for you.

If you don’t have a CRN you'll need to visit a service centre and confirm your identity.

Where you can find your CRN

If you don’t know your CRN, you can find it on:

  • your concession card, if you have one from us
  • letters we've sent you
  • your parents’ Centrelink account or documents if they got Family Tax Benefit (FTB) for you.

If you can’t find your CRN you can call us or visit a service centre.

When your parents need a CRN

If you’re a dependent student, apprentice or job seeker we’ll give your parents a CRN when you claim your payment. If they already have a CRN, we’ll use that one. We’ll use it to help assess their income and work out how much you can get.

We’ll also assess your parents’ income each year for the annual parental income review. Your parents can tell us their income by using their CRN to set up a Centrelink online account. If they can’t find their CRN, they can use the One Time Access Code in the letter we sent you. They can use this code and your CRN to use the Advise Parental Income service.
