You received a renewal of your 03 C&R license early and unsolicited??? I would think you have to apply for a renewal.
As far as the wallet card, that could be something new for convenience. It would beat having to keep a folded copy of the licence in your wallet. For those unexpected opportunities.
I assume that this new license has the correct number, matching your old license?? Still, this is all strange. Something is not right here. Call up the BATFE and find out what is going on.
