FBR number

Weird question, but when you eventually do get accepted to be on the foreign birth registry, do you have to wait until the forms get sent back to you to see the number? Or on your congratulations email do they tell you it. I’m on a really tight time frame (I know that’s completely on me) and just wanted to know if it’s on the email to save a lot of time so I don’t have to wait for the forms to be returned back to me! I’m in Australia so they take a while to get back to us is all.
