Change Your Display Name in Yahoo Mail Settings
To change the name that appears when you send emails from Yahoo Mail, go to your Account Info page, find the Name field under Personal Info, and type in the name you want to display. Yahoo Mail separates your account username (the part before @yahoo.com) from your display name — so you can keep your login the same while changing how your name appears to recipients.
The display name is what people see in the "From:" line when they receive your message. Your username stays the same and cannot be changed through this process. If you need to change your actual Yahoo account username, that requires a different process and has stricter limitations.
Key Takeaways
- Your display name (what recipients see) and your username (your login) are separate — you can change the display name without touching your username.
- Display name changes take effect when ready on new emails you send, but recipients may see the old name on emails already in their inbox.
- You access the display name field through Account Info in your Yahoo account settings, not through the Mail app itself.
- If you want to change your actual Yahoo username (the part before @yahoo.com), you will need to create a new account, as usernames cannot be modified once created.
Step-by-Step: Updating Your Display Name
Start by signing into your Yahoo Mail account. In the top right corner, click on your account icon (usually your initial or profile picture), then select Account Info from the dropdown menu. You may be asked to verify your identity with a code sent to your recovery email or phone number — this is a security step and takes about two minutes.
Once you are in Account Info, look for the Personal Info section on the left side of the page. Click on it, and you will see a field labeled Name. This is where your current display name appears. Click in that field, delete the existing text, and type the name you want to display on your emails. You can use your full name, a nickname, a business name, or any combination of text you prefer.
After you type your new name, scroll down and click the Save button. Yahoo will confirm the change with a message at the top of the page. The new name will appear on all emails you send from that point forward. If you have multiple Yahoo email addresses, you will need to repeat this process for each one separately.
What Changes and What Stays the Same
Your display name change affects only how your name appears to other people — it does not change your email address or username. If your email is jane.smith@yahoo.com, that address remains the same even if you change your display name to "Jane" or "JS Consulting." People will still send emails to jane.smith@yahoo.com, and you will still log in with that username.
The change takes effect when ready on new messages. However, if someone has already received an email from you with your old name, that old name will still show in their inbox on that message. They will only see your new name on emails you send after the change is made. This is normal behavior across all email systems.
If You Want to Change Your Username Instead
Your Yahoo username (the part before @yahoo.com) cannot be changed once it is created. If you want a different email address, you will need to create a new Yahoo account with the username you want. You can then forward emails from your old address to the new one, or set up both addresses in the same Mail app so you can send from either one.
To create a new Yahoo account, go to the Yahoo sign-up page and follow the steps to register a new email address. Once it is active, you can add it to your existing Mail app by going to Settings > Accounts and clicking "Add Account." This way you can manage both addresses in one place without losing access to your original account.
Troubleshooting Display Name Changes
If your new display name does not appear after you save it, try signing out of Yahoo Mail completely and signing back in. Sometimes the change needs a fresh login to show up in the Mail interface. Clear your browser cache if the old name still appears — cached data can sometimes display outdated information.
If you see an error message when trying to save, check that you have not used special characters that Yahoo does not allow, such as quotation marks or angle brackets. Stick to letters, numbers, spaces, hyphens, and apostrophes. If the save button is grayed out, you may not have made any actual changes to the name field — try deleting the current text and retyping it even if it looks the same.
Using Multiple Display Names
Yahoo Mail does not allow you to set different display names for different recipients or different times. You have one display name per email address. If you need to send emails under different names — for example, both as yourself and as a business — you will need separate Yahoo email addresses, each with its own display name.
You can manage multiple Yahoo addresses in one Mail app by adding them all to your account. Go to Settings > Accounts > Add Account and sign in with each Yahoo address you own. Then when you compose a new email, you can choose which address to send from using the "From:" dropdown in the compose window.
Frequently Asked Questions
Will changing my display name affect my contacts or email history?
No. Your contacts list, folders, and all past emails stay exactly the same. Only the name that appears on new outgoing messages changes. People who have you in their contacts will see whatever name they saved for you, not your display name.
Can I use special characters or emojis in my display name?
Yahoo Mail accepts letters, numbers, spaces, hyphens, and apostrophes. Avoid quotation marks, angle brackets, and other special symbols — they will cause an error when you try to save. Emojis are not supported in the display name field.
How long does it take for my new display name to show up?
The change is when ready on your end. New emails you send will show your new name right away. Recipients will see the new name on emails sent after the change, but old emails in their inbox will still show your previous name.
What if I forgot what my current display name is?
Go to Account Info > Personal Info and look at the Name field — that is your current display name. You can also send yourself a test email and check what name appears in the "From:" line to see what others are seeing.
Can I change my display name back to what it was before?
Yes. Go back to Account Info > Personal Info, clear the current name, type your old name, and click Save. There is no limit to how many times you can change your display name.
