Changing your account name

Your Squarespace 5 site comes with a built-in domain (also known as a built-in URL, Squarespace URL, or Account ID), which was automatically created when you signed up. It's made up of your account name followed by the squarespace domain:

Before you begin

  • Changing your account name changes how you log into your site.
  • Your built-in domain is an important part of how Squarespace works and can't be removed. However, you can hide your built-in domain from visitors with a custom domain, by registering a Squarespace Domain or connecting a domain from another provider.
  • For security purposes, you'll always see your built-in domain in your browser address bar when you're logged in, even if you have a custom domain.
  • Changing the account name won't affect custom domains.

Formatting requirements

Your account name needs to follow specific formatting:

  • It must be between 3 and 25 characters in length.
  • All characters must be lowercase.
  • It can't begin with a number.
  • It can include dashes, but no spaces or any other special characters (*,$,%, etc.).
  • It must be unique and not already in use by another Squarespace account.

Change your built-in domain

To change your account name:

  1. Log into your site.
  2. In the Website Management bar, click Website Settings.
  3. Click the Advanced tab.

  1. Scroll down to the Change Account Name section and change the name in the Account Name field.
  2. Click Update Account Name.
  3. Click Confirm.

Your built-in domain is now your new account name followed by


Next steps

Now that you've updated your account name and built-in URL:

  • Use the new account name when logging into your site.
  • Your old built-in domain name will not redirect to your new account name. If you don't have a custom domain, visitors will need to use the new site URL to access your site.
  • Any links to pages on your site that used the old built-in URL won't redirect. You'll need to manually update them.
