I will soon take part in my first congress in the USA.

What piece of identification is needed to register on the first day?

I don't want to carry my passport with me all the day of the conference so is a driver licence sufficient?

    I think this is a question you should direct to the organisers. You'll only get speculation here based on prior experience, which might be helpful, however you could run into issues if there are genuine ID requirements.

If you're registered as a student (or some other role that gives you a discount) then you may need to bring proof of that, but otherwise I've never attended a conference and had to bring anything in order to register.

If the organisers of the conference expect you to bring something then they'd almost certainly tell you. Check the information you've been given, and if they say nothing about bringing proof of ID then you don't need it.

    Right. I've been asked for "some form of ID" at a few conferences, but most often it's juts walk up to the desk, say your name, and get handed your badge. Commented Sep 16, 2016 at 15:49

    Even though rare, there are some conferences where ID is required, but generally any government-issued form of tamper-proof picture ID should be sufficient. There are exceptions, but those exceptions generally involve the US government and should be clearly stated on the conference registration page.

I have attended a few conferences or workshops held inside (US) government owned facilities, and for those I had to show ID at the gate. In the case of the site where highly classified work is done my foreign colleagues had to provide extra documentation before coming and we all I had to promise to stick to certain parts of the facility and to return our temporary badges before leaving.

That's the only circumstance in which I've been asked for ID on showing up for a conference.
