It is only available digitally though right? Is an actual stamp available that says E-Stamp? If not you would not have a scott number for it, so I am a bit confused.

An electronic Duck Stamp, or E-Stamp, is a digital version of the Federal Duck Stamp that allows hunters to purchase and use the stamp immediately for hunting migratory waterfowl. <snip> and a physical stamp is typically mailed to the purchaser after the hunting season concludes.
So it looks like you eventually get a hard copy , but I wonder if the mailed version has the E-Stamp on it.
