Overview
- Users can create a new @gmail.com address while the old one becomes a permanent alias that still receives mail.
- The original address continues to work for signing in to Google services, and all account data remains intact.
- Google limits changes to once every 12 months with a lifetime maximum of three address changes per account.
- The alias cannot be deleted or reassigned to another user, which prevents reuse but preserves the old handle.
- Google warns of potential issues for Chromebooks and third‑party “Sign in with Google” logins, with manual updates or device reconfiguration recommended.
