I want to go back to using my Austpost Business account, but how to add email address of buyer.

Is the super long jumbled up email reference that ebay attach to a sale the only email reference that I can use when using aust post labels?

Looked at it the other day and couldn't believe the number of letters and digits shown, is this the only one that I can reference? Or do some other sellers have some  way of typing in something else? I ended up using their label. 

Thanks in advance for any help.

Don't really want to us eBays labels, want to keep labels separate from them is possible. 

Thanks again.

Thanks to everyone for your comments and suggestions.

I have just worked out what I was doing wrong, I thought something had changed, so now moving forward again.
