Overview
- When you pick a new @gmail.com address, your old address becomes a permanent alias that still receives mail and can be used to sign in to Google services.
- Google’s documentation limits changes to once every 12 months with a maximum of three lifetime changes, and the alias cannot be deleted or reassigned.
- All account data—emails, contacts, photos and files in Drive—remains intact, so users do not need to create a new account or migrate content.
- The feature is not yet available to everyone and surfaced first on a Hindi support page, suggesting regional testing before wider availability and no formal announcement yet.
- Google notes possible temporary issues after a change, including Chromebook sign‑in loops and broken “Sign in with Google” on third‑party sites, which may require manual updates.
