As others have mentioned, the US Federal government issues passports and passport cards, yet it's entirely up to the agency that wants ID what IDs they will accept. I've been turned down for using a passport card for some Washington State government activities ("the card doesn't have a signature"), using a passport to buy an age-restricted item from a store ("we can't scan it"), and a passport card with the state's largest credit union ("too much fraud with passport cards").
Yet none of these are documented anywhere. Everyone just assumes you'll have a state-issued driver license and if you don't, well, you're obviously up to something nefarious. (Before anyone asks, I do have a state-issued enhanced identification card. It looks identical to a driver license, except it says "identification" on it. I've still been told "that's not a driver's license, I can't take that.")
