Your email address is the name you chose plus the domain where your account lives

Your email address is made of two parts joined by an @ symbol. The first part is the username you picked when you created the account — it might be your name, a nickname, or something you made up. The second part is the domain, which is the email service provider's name. So if you created an account at Gmail and chose the username "sarah.martinez", your full email address would be sarah.martinez@gmail.com.

You use this address to send and receive messages. Other people type it in to reach you. You also use it to sign into your email account, along with your password. If you have forgotten what email address you use, or you are not sure which one is yours, there are straightforward ways to find it.

Key Takeaways

  • Your email address combines a username you chose with a domain name (like gmail.com or yahoo.com), separated by an @.
  • If you are signed into your email account on a computer or phone, you can usually see your address at the top of the screen or in account settings.
  • If you have lost access to your account, the email address you used to create it is the one you need to recover it.
  • Different email providers store your address in different places, but all of them show it somewhere in your account menu.

Where to find your email address if you are already signed in

If you are already logged into your email account, the easiest place to look is the top right corner of the screen. Most email services — Gmail, Yahoo Mail, Outlook, and others — display your email address or a shortened version of it near the sign-out button. On Gmail, it often appears next to a profile picture or initial.

If you do not see it there, go to your account settings. In Gmail, click the gear icon in the top right and select "See all settings." In Yahoo Mail, click the account icon and look for "Account info." In Outlook, click the settings icon (usually a gear) and select "View all Outlook settings." Your email address will be listed on the account page, usually under a heading like "Email address" or "Account."

How to find your email address if you are not signed in

If you cannot remember your email address and you are not signed into the account, you will need to use the password recovery process. Go to the sign-in page of the email service you think you used — gmail.com, yahoo.com, outlook.com, or another provider. Click the link that says "Can't sign in?" or "Forgot password?"

The service will ask you for information to prove you own the account. This might be a phone number, a recovery email address you set up, or answers to security questions. Once you verify your identity, the service will show you the email address associated with that account, or it will send a password reset link to a recovery address you provided.

What to do if you have multiple email addresses

Many people have more than one email address — perhaps one for work, one for personal use, and one for shopping. If you are trying to remember which address you used for a specific purpose, think about when and where you created it. Did you sign up for a service at work? That was probably your work email. Did you create an account at an online store? That was likely a personal email.

If you use Gmail, Yahoo, or Outlook, you can check which addresses are connected to your account. In Gmail, go to "Manage your Google Account" and click the "Personal info" tab — you will see all email addresses linked to that account. In Yahoo and Outlook, the account settings page shows connected addresses as well. If you still cannot find the right one, check your email inbox for confirmation messages from services you have signed up for — those messages will show which address received them.

Understanding email address formats and variations

Email addresses follow a standard format, but there are small variations depending on the provider. Most addresses use lowercase letters, numbers, and periods or underscores. Some providers allow plus signs — for example, you might use sarah.martinez+shopping@gmail.com to separate shopping emails from personal ones, though both versions go to the same inbox.

Your email address is case-insensitive, meaning Sarah.Martinez@Gmail.com and sarah.martinez@gmail.com are the same address. However, you should always write it in lowercase when giving it to others, because it is clearer and less likely to cause confusion. The domain part — everything after the @ — must be spelled exactly as it appears, or messages will not reach you.

Why you need to know your email address

Your email address is how you sign into your account and how other people contact you. It is also the key to recovering your account if you forget your password. Many services — banks, social media platforms, shopping sites — use your email address as your username. If you lose track of which email address you used to create an account somewhere, you will not be able to sign back in or reset your password.

Keeping a record of your email addresses in a safe place is a good habit. You might write them down in a notebook, store them in a password manager, or keep a list in a document on your computer. This way, if you need to recover an account or remember which address you used for a service, you have a reference to check.

Frequently Asked Questions

Can I change my email address?

Most email providers let you add additional email addresses to your account, but changing your primary address is more complicated. Gmail and Outlook allow you to add a new address and make it your primary one, but the old address remains linked to the account. Yahoo has similar options. Check your provider's account settings for "Add email address" or "Change primary email."

What if I forgot the password but remember my email address?

Go to the sign-in page and click "Forgot password?" or "Can't sign in?" You will be asked to enter your email address, then the service will send a password reset link to that address or ask you to verify your identity using a phone number or recovery email. Follow the steps to create a new password.

Is my email address private?

Your email address is not completely private — people you email can see it, and services you sign up for store it. However, you can control who sees it. Do not post it publicly on social media or websites unless you are comfortable receiving messages from strangers. When you sign up for services, read their privacy policy to understand how they will use your address.

Can two people have the same email address?

No. Email addresses are unique — each one belongs to only one person. If someone else has already chosen the username you want, you will need to pick a different one. You can try adding numbers, a middle initial, or a period between your first and last name to create a variation.
