To expedite the check-in process, we’ll begin badge pickup on Monday, May 6, at Shoreline Amphitheatre. To give you your Google I/O badge, we’ll need to:

  • Verify your photo ID. We’re OK with government-issued licenses, passports, and other forms of identification. If you don’t have proper identification, you won’t be able to receive a badge and won’t be admitted into the conference. The name on your ID needs to be an exact match of your registration profile. If you’re an Academic attendee, please remember to bring proof of eligibility.
  • Scan your registration QR code received via email. You can scan it from your phone—no need to print the email! #savetheenvironment

Please note, you may not share, give, or otherwise provide your badge to anyone. Google I/O badges aren’t replaceable, so don't lose yours or you won’t be readmitted to the conference. You must wear your Google I/O badge to gain admission to Google I/O, including the Sessions, Sandboxes, and After Dark. If requested by security, please display or provide additional identification.

Google I/O is an outdoor developer event, so please be comfortable and casual. There is no enforced dress code. The Bay Area can get very hot during the day and chilly in the evenings, so take this into consideration when planning your attire.
Good news, we like food, too! Attendees are offered complimentary breakfast, lunch, and snacks on all three days of the conference. Dinner will also be available on Day 1 and 2 during the After Dark events.
We got your back! The lost and found station will be located at the Conference Information Desk during event hours. Any items left overnight will be turned over to the Conference Security Office. One important detail: Google I/O badges are NOT replaceable, so don't lose yours or you won’t be readmitted to the conference.
These are two nights of food, drinks, and fun you should stick around to see. The night of May 7 will be an experimental celebration which will take over I/O, and on the night of May 8, we'll have an exclusive concert in the Amphitheatre. Food and drinks will be available on both nights (alcoholic beverages available for those 21 and over).

All participants of Google events must abide by the following policy:

Be excellent to each other. Treat everyone with respect. Participate while acknowledging that everyone deserves to be here — and each of us has the right to enjoy our experience without fear of harassment, discrimination, or condescension, whether blatant or via micro-aggressions. Jokes shouldn’t demean others. Consider what you are saying and how it would feel if it were said to or about you.

Speak up if you see or hear something. Harassment is not tolerated, and you are empowered to politely engage when you or others are disrespected. The person making you feel uncomfortable may not be aware of what they are doing, and politely bringing their behavior to their attention is encouraged.

Practice saying "Yes and" to each other. It’s a theatre improv technique to build on each other’s ideas. We all benefit when we create together.

We have a ZERO TOLERANCE POLICY for harassment of any kind, including but not limited to:

  • Stalking/following
  • Deliberate intimidation
  • Harassing photography or recording
  • Sustained disruption of talks or other events
  • Offensive verbal language
  • Verbal language that reinforces social structures of domination
  • Sexual imagery and language in public spaces
  • Inappropriate physical contact
  • Unwelcome sexual or physical attention

In relation to, but not limited to:

  • Neurodiversity
  • Race
  • Color
  • National origin
  • Gender identity
  • Gender expression
  • Sexual orientation
  • Age
  • Body size
  • Disabilities
  • Appearance
  • Religion
  • Pregnancy

Participants asked to stop any harassing behavior are expected to comply immediately. Our zero-tolerance policy means that we’ll look into and review every alleged violation of our Event Community Guidelines and Anti-Harassment Policy and respond appropriately. We empower and encourage you to report any behavior that makes you or others feel uncomfortable by finding a Google staff member or by emailing

Event staff will be happy to help participants contact hotel/venue security or local law enforcement, provide escorts, or otherwise assist those experiencing discomfort or harassment to feel safe for the duration of the event. We value your attendance.

This policy extends to Sessions, forums, workshops, Codelabs, social media, parties, hallway conversations, all attendees, partners, sponsors, volunteers, event staff, etc. You catch our drift. Google reserves the right to refuse admittance to, or remove any person from, any Google-hosted event (including future Google events) at any time in its sole discretion. This includes, but is not limited to, attendees behaving in a disorderly manner or failing to comply with this policy, and the terms and conditions herein. If a participant engages in harassing or uncomfortable behavior, the conference organizers may take any action they deem appropriate, including a warning or expelling the offender from the conference with no refund.
