A guy that sent me $2,000 and his paypal transaction is on hold as he is a new paypal customer. Paypal told me he needs to send in, pay the invoice to get the 4 digit code or I have to wait 14 days.
In order to make sure it isn't a stolen credit card, PayPal requires that the customer verify that he is who he says he is by entering a four digit number that will show up on his next credit card invoice. It is standard procedure on new accounts for payments over a certain minimum.
