Overview
- Google is making the feature available to U.S. accounts after a quiet pilot in India in late 2025, with some users seeing it in stages.
- Users can swap the part before @gmail.com, keep all account data, and have messages sent to both old and new addresses land in the same inbox.
- Sign-in works with either address across Google services, and you can send email from both identities.
- Google caps changes to one new address every 12 months with a lifetime limit of three, does not let you delete the new address, and prevents anyone else from claiming your old one.
- Google advises backing up data and checking third-party logins and app settings before switching, and it has not given a timeline for other countries.
