The number you need isn't your paypal transaction number, its a number you breifly see before you even pay for your account (before you get to the paypal site). This page does not tell you to save this number nor gives any hint that it is even remotly important!

I highly suggest putting in huge bold red letters on that page (Because red clashes with Green):

Save this number for future use as it may be the only way to recover your account in the case of account theft!
