Your Xfinity account number is printed on your bill and visible in your online account
Your Xfinity account number is a unique identifier that Comcast assigns to your service. You need it to pay your bill, contact customer service, or make changes to your account. The fastest way to find it is to look at your paper bill — it appears near the top, usually next to your name and service address. If you do not have a bill in front of you, you can log into your Xfinity account online or through the Xfinity mobile app and find it there as well.
The account number is different from your username or password. It stays the same for as long as you have service at that address, even if you change your service plan or billing method. Knowing where to find it saves time when you call Xfinity or need to pay over the phone.

Finding your account number on your paper bill
Open your most recent Xfinity bill. The account number is printed in the upper left or upper right corner of the first page, directly above or below your name. It is usually a 10-digit number, though some accounts may have a slightly different format. The bill header also shows your service address, so you can confirm you are looking at the right account if you have multiple services.
If you have misplaced your bill, you can request a replacement by calling Xfinity customer service at 1-800-934-6489. They can read your account number to you over the phone or email you a copy of your bill. Keep in mind that Xfinity typically mails bills monthly, so if you are looking for a very recent bill, it may not have arrived yet.
Locating your account number online
Go to xfinity.com and sign in with your username and password. Once you are logged in, look for "Account" or "My Account" in the top navigation menu. Click on it, and you will see your account number displayed prominently on the account overview page. It is usually shown near your name and service address.
If you use the Xfinity mobile app, the process is the same. Open the app, sign in, and tap the account icon (usually at the bottom of the screen). Your account number will be visible on your account summary. The app also shows your current bill balance, due date, and payment history, so it is a useful place to check your account status anytime.
What to do if you cannot find your account number
If you cannot locate your account number through your bill or online account, call Xfinity customer service at 1-800-934-6489. Have your name, service address, and phone number ready. The representative will look up your account and provide the number. This usually takes less than a minute.
You can also visit an Xfinity store in person if one is near you. Staff can print your account information or write down your account number for you. Find store locations at xfinity.com/locations.
Using your account number to pay your bill
When you pay your Xfinity bill by phone, the automated system or a representative will ask for your account number. Have it ready before you call to speed up the process. You can pay by phone at 1-800-934-6489, or you can enter your account number on the Xfinity website to make a one-time payment or set up automatic payments.
If you pay in person at a store or through a third-party payment service, you may also need your account number to ensure the payment is credited to the correct account. Some payment methods, like online bill pay through your bank, may ask for your account number as well.
Protecting your account number
Your account number is not as sensitive as your password or Social Security number, but you should still treat it with care. Do not share it with people you do not trust, and do not post it on social media or in public forums. Scammers sometimes use account numbers to pose as customers and attempt to change account details or request refunds.
If you suspect someone has used your account number fraudulently, contact Xfinity immediately at 1-800-934-6489. They can review your account for unauthorized changes and help you secure it. Check your bill regularly to catch any charges you do not recognize.
Frequently Asked Questions
Is my account number the same as my customer ID?
Yes, Xfinity uses the terms interchangeably. Your account number and customer ID are the same 10-digit identifier. You may see either term used on your bill or in customer service conversations.
Can I pay my Xfinity bill without my account number?
You can pay online using your username and password instead of your account number. However, if you pay by phone or in person, having your account number on hand makes the process faster and reduces the chance of a payment being applied to the wrong account.
What if I have multiple Xfinity accounts?
Each service address has its own account number. If you have internet at one address and TV at another, those are separate accounts with separate numbers. Check your bills to confirm which number goes with which service.
Will my account number change if I move?
No. If you move and keep Xfinity service at your new address, you will receive a new account number for the new location. Your old account number will close when service ends at the previous address.
