SAEDNEWS: Simple Guide to Changing Your Gmail Username on Phone and Laptop with Profile Settings, Google Account Management, and Email Information Editing
According to Saednews: After years of anticipation, Google has finally enabled a feature that allows some users (currently rolling out in the United States) to change their Gmail username without needing to create a new account. This update removes the long-standing limitation that forced users to start over with a new email address.
The new capability provides greater flexibility and helps users move away from old, unprofessional, or outdated email addresses while keeping their existing Google account intact.
To ensure account security and prevent abuse, Google has introduced several restrictions:
You can change your Gmail username only once every 12 months
A maximum of three username changes is allowed during the lifetime of an account (four total addresses including the original)
If you change your username and then reconsider, you must wait 30 days before selecting a new one again
These rules help maintain account stability while giving users more control over their email identity.

One important aspect of this update is that your original email address is not deleted. Instead, it is kept as an alternate email.
This ensures that:
Emails sent to your old address are still delivered to your main inbox
You may still be able to send emails using your previous address
Your contacts will not be disrupted or confused by sudden changes
To update your Gmail username, follow these steps:
Click your profile icon in any Google service to open your Google Account
Select Manage your Google Account
Go to the Personal Info section
Open Email, then click your Google Account email
Choose Change Google Account email and complete the identity verification and new username setup process
This update makes Gmail more flexible and user-friendly, especially for those who want a more professional or updated email identity without losing their existing data or contacts.
