Account registration: Error 'AccountAlreadyExists' encountered

Problem

An error message, {"errorCode":"AccountAlreadyExists"}, appears when attempting to complete JetBrains Account registration using a company license invitation link. This prevents logging in and using the purchased IntelliJ IDEA Ultimate license.

Cause [Optional]

The user registered a JetBrains Account via GitHub SSO. This GitHub account has an alias email address that was marked as verified in the GitHub but later the alias was disabled. This results in a mismatch or conflict between account records and the associated license.

Resolution

1. Open the JetBrains Account Profile Details page and log in with your current account credentials.

2. Verify that the account email matches the one associated with your license (realemail@company.com).

   • If it is not the same, update the email on your JetBrains Account to realemail@company.com.

3. Use the license invitation link to complete registration again.

If the issue persists despite following these steps, contact JetBrains Support and share a screenshot of your Profile Details page on the JetBrains Account.

Additional Information

• This is a known issue internally and is being actively tracked by the JetBrains team.
