What's the BIN number for the Citi Prestige card (i.e., the first 6 digits of the card). I got approved online last night and email the concierge to see if they could book something for this Saturday (6 days from now). Citi told me I'd have the card in three business days, so I told them I'm trying to book something in advance of having the physical card. They said they couldn't book anything for me until I tell them the BIN number (the first six numbers of the card). Appreciate any help you can give, since this will save me ~200USD.
