Your username is the account name you created when you set up your Comcast or Xfinity service, not your email address or account number
Your Comcast username is the login name you chose during account setup — it's separate from your email address, phone number, or account number. You use it to sign into Xfinity.com, the Xfinity app, or the Xfinity Stream app to manage your bill, check your data usage, or restart your modem remotely. If you've forgotten it, you can recover it in a few minutes using your account information.
The username is not the same as your Comcast account number (the number on your bill) or your email address. Many people confuse these three things, which is why recovery takes longer than it should. Knowing which one you need before you start saves time.
Key Takeaways
- Your Comcast username is the login name you created during account setup, separate from your email address or account number.
- You can recover your username on Xfinity.com by entering your account number, service address, and phone number associated with your account.
- If you don't remember your account number, you can look it up using your service address and phone number instead.
- Once you recover your username, you can use it to log into Xfinity.com, the Xfinity app, or Xfinity Stream on any device.
How to recover your username on Xfinity.com
Go to Xfinity.com and click "Sign In" in the top right corner. On the sign-in page, look for the link that says "Forgot username?" or "Need help signing in?" — the exact wording changes, but it's always near the password field. Click it.
Comcast will ask you to enter your account number, the service address on file, and the phone number associated with your account. If you have your bill in front of you, this takes two minutes. Your account number is printed on the front of your bill, usually in the upper right corner. The service address is where your internet, TV, or phone service is installed — not a mailing address if it's different.
After you enter this information, Comcast displays your username on the screen. Write it down or take a screenshot. You can then use it to sign in when ready.
What to do if you don't remember your account number
If you don't have a bill handy, you can still recover your username, but the process takes a step longer. On the same "Forgot username?" page, look for an option that says "Don't have your account number?" or "Look up your account." Click it.
Comcast will ask for your service address and the phone number on file instead of your account number. Enter both, and the system will pull up your account and display your username. This route works as long as the phone number and address match what Comcast has in their system.
If you've changed your phone number or address
If the phone number or address you enter doesn't match Comcast's records, the online recovery tool won't find your account. In this case, you'll need to contact Comcast directly. Call 1-800-XFINITY (1-800-934-6489) and have your account number ready if you can find it, or be prepared to give the service address and any phone number that was on file when you opened the account.
A Comcast representative can verify your identity using other information — the last four digits of a Social Security number, a recent bill amount, or answers to security questions you set up. Once verified, they can tell you your username or reset it to something new if you prefer.
Resetting your username instead of recovering it
If you want a new username instead of recovering the old one, you can create a new login during the recovery process. After Comcast displays your current username, look for an option to "Create a new username" or "Change your username." You'll choose a new one on the spot and can start using it when ready.
This is often faster than trying to remember an old username you haven't used in years. The new username works right away on Xfinity.com, the Xfinity app, and Xfinity Stream.
Usernames vs. email addresses for Xfinity login
Comcast allows you to sign in using either your username or the email address associated with your account. If you know your email address but not your username, you can straightforward use the email to log in — you don't need to recover the username at all. This is often the easiest route if you set up your account using an email you still use.
However, some older accounts or accounts set up in-store may not have an email on file. In those cases, you'll need your username to sign in online.
Frequently Asked Questions
Is my Comcast username the same as my email address?
No. Your username is a separate login name you created during setup. Your email address is different and can also be used to sign in, but they are not the same thing. If you know your email, you can use it instead of your username.
Can I change my username after I recover it?
Yes. Once you sign in to Xfinity.com with your recovered username, go to your account settings and look for "Username" or "Login credentials." You can create a new username there. The change takes effect when ready.
What if I never created a username because I always used my email to sign in?
You don't need a username if you've been signing in with your email address. You can continue using your email to access Xfinity.com and the apps. A username is optional for accounts that have an email on file.
How long does it take to recover my username?
If you use the online recovery tool on Xfinity.com, your username appears on screen when ready. If you call Comcast, a representative can tell you your username within a few minutes after verifying your identity.
Can I recover my username on the Xfinity app instead of the website?
The Xfinity app has a "Forgot username?" option on its sign-in screen that works the same way as the website. You enter your account number and service address, and the app displays your username. The process is identical on both platforms.
