Do I need a government issued ID to travel if I am 16 years old? Can I just use my student ID?

Bring any ID you have and your Social Security card. Passport if you have one. Student I'D may not work cause anybody can make that cheap card

I think you're under age to travel alone , I think you need to be 18 years old. I know you could travel within the United States with a ID card from your local DMV of your State, if you're flying out of the United States you will need a passport and if you're traveling out of the United States.
