Overview
- Google's help pages confirm users can replace the username on an @gmail.com address while keeping emails, files, photos and settings intact.
- The original address is kept as an alias so messages sent to it still arrive and users can sign in with either address.
- Accounts can make up to three changes with a 12‑month wait between each, and the old address cannot be used to create a new account for 12 months.
- Some older items, such as calendar events or shared documents, may continue to display the original address after the change.
- The rollout is gradual and first visible in Hindi support pages, and Google has not provided a global timeline or formal announcement.
