Start by checking the device or browser where you set up the account

The fastest way to find your email is to look at the computer or phone where you originally created the account. Open the website or app, click "Forgot Password" or "Sign In", and enter any username or phone number you remember. Most systems will show you the email address on file — partially hidden, like "j***@gmail.com" — before asking you to verify it.

If you still have access to that device and browser, check the autofill dropdown. Click on the email field and your browser may show saved addresses you have used before. This works on Chrome, Firefox, Safari, and Edge.

Check your email inbox for account confirmation messages

Search your email accounts for messages from the government agency itself. Look for subject lines like "Confirm your email", "Welcome", "Account created", or the agency name. These messages arrive when you first sign up and usually contain a link to verify your address. The "From" line will show you which email received it.

Search across all your email accounts — Gmail, Yahoo, Outlook, work email, and any others you have used. Use the search term with the agency name, like "IRS" or "Social Security" or "unemployment". If you have not checked an old email account in years, log in and search there too.

Look at your payment or mail records from the agency

Tax refunds, stimulus payments, and benefit payments often arrive with a letter or notice that references your account. Find any letter, check stub, or payment notice from the agency and look for an account number, reference number, or website URL. Visit that website and use the account recovery tool — it will ask for your Social Security number, date of birth, or other identifying information, then show you the email on file.

If you received a debit card with a refund or payment, the card statement or the agency's website tied to that card may show your registered email. Log into the card's online portal using your Social Security number or the card number itself.

Use the agency's account recovery tool directly

Most government websites have a "Forgot Email" or "Account Recovery" option separate from password reset. Go to the main login page and look for a link like "Can't sign in?", "Recover your account", or "Need help?". Click it and follow the prompts — you will usually need to provide your Social Security number, date of birth, and a phone number or alternate email.

The system will then confirm the email address associated with your account. Some agencies, like the IRS and Social Security, also let you call a phone number to verify your identity and have a representative tell you the email on file.

Contact the agency by phone or mail if online tools do not work

If you cannot recover the email online, call the agency's main customer service line. Have your Social Security number, date of birth, and any account number or reference number ready. A representative can verify your identity over the phone and tell you the email address registered to your account.

You can also send a letter to the agency's main office requesting account information. Include your full name, Social Security number, date of birth, and a statement that you need to know the email address on file. Mail it to the address listed on the agency's official website. Response times vary from two to four weeks.

Frequently Asked Questions

What if I do not remember any password or username for the account?

You do not need them. Go to the login page and click the account recovery or "Forgot" link. The system will ask for your Social Security number, date of birth, and phone number instead. Once you verify those, it will show your email and let you reset your password without ever entering the old one.

Can I change my email address once I find out what it is?

Yes. Once you sign in or reset your password, look for "Account Settings" or "Profile" in the menu. Most government websites let you update your email address there. You will usually need to verify the new address by clicking a link sent to it before the change takes effect.

What if I get a message saying the email does not exist in the system?

You may have created the account under a different email than you thought, or the account may not have been fully set up. Try the account recovery tool again with a different email address you have used. If that does not work, call the agency — they can search by Social Security number and phone number instead.

How long does it take to get a response if I mail a request to the agency?

Most agencies respond to mail requests in two to four weeks, though some take longer during high-volume periods. Call the agency first to ask if they have a faster phone-based recovery option, since that usually takes minutes instead of weeks.
