Overview
- Google support pages confirm users can switch to a new @gmail.com address on the existing account and sign in with either address.
- The previous address remains active as an alias that continues to receive email after the change.
- Documentation sets limits of one change every 12 months and a maximum of three lifetime changes.
- The feature is rolling out gradually and first surfaced on a Hindi-language support page, so many users will not see it yet.
- Google advises creating backups before switching, notes you cannot choose an address already tied to another Google Account, and flags possible Chromebook and third‑party sign-in issues that may require reauthentication.
