Just FYI reference numbers have worked less than 50% of the time for me.... and the concencus is correct, If it's from Woody's, it'll be there

In addition to format "X12345" for reference number, I've also seen "LASTNAME12345", "X12345-9999" (plus 4 zip), and "LASTNAME12345-9999" all work.

But yeah, it'll be there.
