Call Comcast's automated payment line to pay by phone without speaking to a representative
You can pay your Comcast bill over the phone using their automated system. Call 1-800-934-6489 and follow the prompts to enter your account number and payment information. The system accepts debit cards, credit cards, and bank account numbers. Payments made this way typically post to your account within one business day.
If you prefer to speak with a person, you can also reach a Comcast representative at the same number and ask them to process a payment. This takes longer than the automated system but may be helpful if you have questions about your bill or need to discuss payment arrangements.
Phone payments work any day of the week, including weekends and holidays. The automated line is available 24 hours a day. If you call during business hours and choose to speak with a representative, wait times vary depending on call volume.

What information you need before calling
Gather these details before you dial. You will need your Comcast account number, which appears on your bill or in the My Account section of the Xfinity website or app. You will also need the payment amount — either the full balance due or a partial payment.
Have your payment method ready: a debit card, credit card, or bank account number and routing number if you plan to pay from a checking or savings account. The system will ask for the card's expiration date and CVV (the three-digit security code on the back), or your bank's routing and account numbers if paying by bank transfer.
If you are calling on behalf of someone else's account, you will need authorization or the account holder's information. Comcast will not process a payment from a third party without the account holder's permission.
How the automated system works step by step
When you call 1-800-934-6489, the automated system will ask you to enter your account number using your phone's keypad. After you enter it, the system confirms your account and reads back your current balance and due date.
Next, you choose your payment amount. You can pay the full balance, the minimum due, or a custom amount. The system then asks you to select your payment method — credit card, debit card, or bank account — and walks you through entering that information.
Once you confirm the payment details, the system provides a confirmation number. Write this down or take a screenshot. The confirmation number is your proof of payment and is useful if you need to contact Comcast later about the transaction.
Bank account payments versus card payments
Paying from your bank account costs nothing and is the cheapest option. Comcast does not charge a fee for bank transfers. You will need your routing number (the nine-digit code that identifies your bank) and your account number. Both appear on the bottom left of your checks.
Credit card and debit card payments are also free through Comcast's phone system. However, if your card issuer charges a cash advance fee or treats utility payments as cash advances, you may see an extra charge on your card statement — this comes from your bank, not Comcast.
If you are trying to avoid fees, paying from your bank account is the safest choice. If you do not have a bank account or prefer not to share that information, a debit card is the next best option.
What happens if the payment does not go through
If your payment is declined, the automated system will tell you immediately and ask you to try again with different information. Common reasons for decline include an incorrect card number, an expired card, insufficient funds, or a card that is flagged for fraud protection by your bank.
If your bank account payment is declined, it is usually because the account does not have enough funds or the routing number was entered incorrectly. Try the payment again with the correct information, or switch to a different payment method.
If you keep getting declined and cannot figure out why, call back during business hours and ask to speak with a representative. They can sometimes see more detail about why the payment failed and may be able to help you troubleshoot or set up a payment arrangement if you do not have the funds available right now.
When to use phone payment versus other methods
Phone payment is fastest if you need to pay immediately and do not want to set up an online account or use the Xfinity app. It is also useful if you do not have internet access or prefer not to enter payment information online.
If you pay regularly, setting up automatic payments through the Xfinity website or app is more convenient — you enter your information once and the payment happens on the same date each month without you having to call. The My Account section of the Xfinity website lets you set this up in a few minutes.
Mailing a check takes longer (usually 7 to 10 days to post) and is only worth doing if you do not have a phone, internet, or bank account. Paying in person at a Comcast store or authorized payment location is an option if you prefer to hand over cash or a check directly, but phone payment is faster and available around the clock.
Frequently Asked Questions
Does Comcast charge a fee to pay by phone?
No. Comcast does not charge a fee for phone payments made through their automated system or to a representative. Your bank or card issuer may charge a fee depending on your account type, but Comcast itself does not add one.
Can I pay someone else's Comcast bill by phone?
You can if you have the account holder's permission and their account number. The system will ask for the account number, not your name, so it does not matter whose account it is. If you are calling on behalf of a family member or authorized user, have their account number ready.
How long does it take for a phone payment to show up on my account?
Payments made through the automated system usually post within one business day. If you call during business hours and speak with a representative, they may be able to process it faster, but one business day is the standard. Do not assume the payment has posted until you see it in your account.
What if I need to cancel or change a payment I just made?
Call 1-800-934-6489 right away and speak with a representative. If the payment has not yet posted to your account (usually within 24 hours), they may be able to cancel it. Once it posts, you will need to contact Comcast to request a refund or credit.
Can I set up a payment plan by phone if I cannot pay the full amount?
You can ask a representative about payment arrangements by calling 1-800-934-6489 during business hours. They can discuss options like splitting your balance across multiple months. The automated system only lets you make a single payment, so you will need to speak with someone to set up a formal plan.
