Is this an actual credit card? Will this card help build my credit? Is it worth getting?

Yes, it is an actual credit card and it will help you improve your credit if used responsibly. It’s a fine option if a significant portion of your monthly spending is with Amazon or if you’re using it to supplement an existing everyday card.

It is a Revolving Credit Account. Yes, it will build your Creditworthiness BUT- It's a flimsy paper card that only works with Amazon. There is also a Visa card available that is a plastic credit card, but remember these people charge high interest. Stick with the Revolving Credit: it builds your Creditworthiness but you can't use it for anything but Amazon, unlike the Visa.

Not only is it a real credit card, it's also a Visa. You can use this card pretty much anywhere in the world.
