Registration FAQ
I’m traveling to the US from another country. How do I get a visa letter to attend I/O?

If you require a visa letter regarding your Google I/O attendance please indicate so when completing the registration form and we’ll email it to you within 7 business days. If you haven’t received your letter or have questions regarding the process, you can contact Google won’t be able to contact an embassy on your behalf.

I got an invitation, but when I try to register it says the event is full.

An invitation is not a guarantee for a ticket. Tickets are first-come, first-served. You can still join in on the fun remotely via I/O Extended and our livestream.

I already confirmed my ticket, but something came up and I won’t be able to attend anymore. Can I cancel?

Yes, you can cancel your ticket until April 30th via your I/O profile. After that date, sales are final and refunds can no longer be issued.

I registered for I/O under my nickname. Will I be able to attend I/O?

No. We’ll need to verify your registration details against a government issued photo ID when you come to pick-up your badge.

I’m under 18 years old. Do I need a parental consent form to attend?

Yes. The official parental consent form will be emailed to you closer to the event, and you must return a signed version over email before picking up your badge onsite.

I need an invoice for my ticket purchase.

While we don’t issue personalized invoices, you can access your purchase receipt in your I/O profile at any time.
