Membership Portal

Welcome to the Seattle Worldcon 2025 Membership Portal.

From here you can create and manage your membership account.

If you don’t already have an account, the next screen will say: “The email (your email address) does not have an account” and we will take you through the steps of creating an account.

This is our way of asking “Are you sure this is the correct email?” If you’re sure then go ahead and create your account.

You will need to create a minimal account for yourself even if you are just buying a membership for someone else if you want to receive a valid receipt for your payment.

Please log in to continue to the Portal.
