What is my Medicare Individual Reference Number?
Take a look at your Medicare card. Your Individual Reference Number (IRN or 'Medicare reference number') is the number to the left of your name on the card.
When you provide your IRN, ensure that you provide the number alongside your name, and not the last digit of your Medicare number.
What's the difference between my Individual Reference Number and my Medicare Card Number?
While your Individual Reference Number is the number to the left of your name on your card, your Medicare Card Number is the 10 digit number that appears above your name, across the top section of the card.
When providing your Medicare number, you must ensure that you include the last digit.
