delivery note

I'm a little stuck... Click here to teach me more about this clue!

'advice' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'by birth certificate?' is the wordplay.
'by' is a charade indicator (letters next to each other).
'birth' becomes 'delivery' (delivery is a kind of birth).
'certificate?' becomes 'note' (I've seen this in another clue).
'delivery'+'note' is 'DELIVERY NOTE'.

'given' acts as a link.

Can you help me to learn more?

(Another definition for delivery note that I've seen is " Paperwork accompanying a consignment".)

I've seen this clue in The Telegraph.
