DEF CON 34 Las Vegas Convention Center

DEF CON will always be a cash-at-the-door conference. We will always honor the LineCon. This is the way.

Preregistration guarantees you'll receive a DEF CON 34 Human badge (as opposed to a paper badge, if we run out) when redeeming your ticket in Las Vegas. Badges must be picked up onsite.

The fine print
DEF CON 34 preregistration ends July 31st at 8:59pm EST. Onsite registration will begin Thursday August 6, 2026.
