Call Comcast's automated payment line at 1-800-934-6489
The fastest way to pay a Comcast bill by phone is to call 1-800-934-6489, which connects you to an automated system that accepts payments 24 hours a day, 7 days a week. You will need your account number (found on your bill or in the Xfinity app) and a debit card or bank account information ready before you call.
The automated system walks you through the payment step by step. You enter your account number using your phone keypad, confirm the amount due, and provide your payment method. The system tells you immediately whether the payment went through. Most payments process the same day if you call before 11:59 p.m. Eastern Time; payments made after midnight may post the next business day.
If you prefer to speak with a person instead of using the automated line, you can call the same number and press the option to reach a representative. Wait times vary depending on call volume, but representatives can process payments just as quickly as the automated system and can answer questions about your account at the same time.

What information you need before calling
Have your account number ready before you dial. This number appears at the top of your printed bill or in the Xfinity app under Account. If you cannot find it, you can look it up on the Xfinity website by signing into your account, but it is faster to have it written down before you call.
You will also need the payment method you want to use. Comcast accepts debit cards, credit cards, and direct bank account payments (checking or savings). Have the card number or routing and account number for your bank ready. The system will ask you to enter this information using your phone keypad, so having it visible makes the call faster.
If you are paying someone else's bill, you will need their account number, not yours. The system does not require you to be the account holder to make a payment, but you do need the correct account number to route the payment to the right bill.
How payments post to your account
Payments made through the automated phone line are processed immediately, but the timing of when they show up on your bill depends on when you call. If you call before 11:59 p.m. Eastern Time on a business day, the payment typically posts the same day. Payments made after midnight or on weekends post on the next business day.
Once a payment posts, it reduces your balance right away. You can check the status of your payment in the Xfinity app or on the Comcast website within a few hours of making the call. The app shows your current balance and a history of recent payments, so you can confirm the transaction went through.
If you are paying to avoid a service interruption, call during business hours so you can confirm the payment posted before the cutoff time. If you call late at night and your service is at risk of being shut off the next morning, ask the automated system to connect you to a representative who can note your payment in the system immediately, even if it has not fully processed yet.
Alternatives if you cannot reach the phone line
If you have trouble reaching 1-800-934-6489 or prefer not to use the phone, Comcast offers other ways to pay. The Xfinity app lets you pay instantly from your phone or tablet using a debit card, credit card, or bank account. You can also pay on the Comcast website at xfinity.com by signing into your account and selecting the payment option.
You can also pay in person at a Comcast service center if one is near you. Find the nearest location on the Comcast website by entering your zip code. Service centers accept cash, checks, debit cards, and credit cards, and staff can answer questions about your bill while you pay.
If you want to set up automatic payments so you do not have to call each month, you can do that through the Xfinity app or website. Automatic payments deduct the amount due from your bank account or card on your due date each month, and you can change or cancel the setup anytime.
What to do if your payment is not accepted
If the automated system rejects your payment, it usually means one of three things: the card or bank account information was entered incorrectly, the card or account has insufficient funds, or there is a temporary issue with the payment processor. The system tells you which problem occurred and gives you the option to try again with different information.
If you entered the information correctly and have sufficient funds, try the payment again in a few minutes. If it fails a second time, call back and select the option to speak with a representative. They can troubleshoot the issue, check whether there are any holds on your account, and process the payment manually if needed.
If your card is being declined repeatedly, contact your bank or card issuer directly to make sure they have not blocked the transaction. Some banks flag payments to utility companies as suspicious activity. Your bank can clear the block, and then the Comcast payment will go through.
Frequently Asked Questions
Is there a fee to pay my Comcast bill by phone?
No. Comcast does not charge a fee for payments made through the automated phone line or with a representative. The only cost is the payment itself. Some third-party payment services charge fees, but calling 1-800-934-6489 directly is always free.
Can I pay my bill if I do not have the account number memorized?
Yes. When you call 1-800-934-6489, the automated system can look up your account using your phone number or service address instead. You will need to provide the phone number or address associated with the account, and the system will retrieve your account number for you.
What if I want to pay only part of my bill?
The automated system lets you enter any amount you want to pay, not just the full balance due. You can pay a partial amount, and the remaining balance will carry over to your next bill. Just enter the amount you want to pay when the system asks.
How long does it take for a phone payment to show up on my bill?
Payments typically post within a few hours if you call during business hours on a weekday. You can check the status in the Xfinity app or on the website shortly after you hang up. If you call after hours or on a weekend, the payment posts on the next business day.
Can I get a receipt for my phone payment?
Yes. The automated system provides a confirmation number at the end of the call. Write it down or take a screenshot if you are using a mobile phone. You can also view your payment history and receipts in the Xfinity app or on the Comcast website anytime.
