I'm not 100% sure, but I'm going to assume they didn't always exist because I don't see any when I look up old transactions.

The "reference number" you posted (and the Graal order ID shown in PayPal details) is actually the same order ID we ask for. It just doesn't have those leading letters that make up what we call the WEB order ID.

( WEB order ID format is just 3 random letters + the 5-6 digit Graal order ID )

The WEB order ID is currently shown on the web site during checkout and is e-mailed to you afterward.

If you don't have the WEB order ID, we can generally find a way to verify ownership without it. A copy of the entire PayPal receipt is usually sufficient, and if you have a PayPal account like most people do it's always accessible under the History tab at their web site.
