The main Comcast customer service number for bill payments is 1-800-934-6489
Call this number to pay your Comcast bill over the phone using a debit card, credit card, or bank account. The automated system will walk you through entering your account number and payment amount. You can also speak to a representative if you prefer to discuss your bill or set up a payment plan before paying.
The line is available 24 hours a day, 7 days a week. Wait times are typically shorter during off-peak hours — early morning, late evening, or weekday afternoons tend to be less busy than evenings or weekends.

What information you need before calling
Gather your Comcast account number before you dial. You can find it on your bill, in the Comcast app, or on your online account page. If you do not have your account number handy, the system can look up your account using your phone number or service address, but having the number ready will speed things up.
You will also need your payment method — either a credit card, debit card, or bank account information. The system accepts Visa, Mastercard, American Express, and Discover. If you are paying from a bank account, have your routing number and account number ready.
How the automated payment system works
When you call, the automated system will ask you to enter your account number using your phone keypad. It will then tell you your current balance and ask how much you want to pay. You can pay your full balance, a partial amount, or a set dollar figure.
After you enter your payment amount and payment method details, the system will confirm the transaction and give you a confirmation number. Write this number down or note it in your phone — you may need it if you have questions about the payment later. The payment is processed when ready, though it may take one business day to show in your account.
Speaking to a representative instead of using automation
If you reach the automated system and want to speak to someone, you can usually press 0 or say "representative" to transfer to a live agent. Representatives can answer questions about your bill, discuss why your balance is higher than expected, or set up a payment plan if you cannot pay the full amount right now.
Representatives can also help if you believe a charge is wrong, if you want to dispute a fee, or if you need to make a payment arrangement due to hardship. They have access to your full account history and can sometimes remove or reduce fees as a courtesy.
When payments post and what to expect
Payments made by phone before 11:59 p.m. Eastern Time typically post to your account the same business day. Payments made after that time or on weekends may not post until the next business day. Once posted, the payment reduces your balance when ready, and your next bill will reflect the updated amount owed.
You will receive a confirmation number at the end of your call. Comcast does not automatically send a receipt by mail or email for phone payments, so keep your confirmation number in case you need to reference the transaction. You can also log into your online account or use the Comcast app to see the payment listed in your transaction history within a few hours.
Other ways to pay if you prefer not to call
If calling is not convenient, you can pay your Comcast bill online through your account portal, through the Comcast app, by mail, or in person at a Comcast service center. Online and app payments process the same day if made before the cutoff time. Mail payments take 7 to 10 business days to reach Comcast and post to your account.
You can also set up automatic payments so your bill is paid from your bank account or card each month without calling or logging in. This option is available through your online account settings or by asking a representative when you call.
What to do if you cannot pay the full amount
If you cannot pay your full balance, call the same number and ask to speak to a representative about a payment plan or arrangement. Comcast offers options for customers facing temporary hardship, including extended payment plans that spread your balance over several months. The representative can discuss what arrangements are available based on your account history and current situation.
Paying something, even a partial amount, shows good faith and may help you avoid late fees or service suspension. If you are struggling with your bill, it is better to call and discuss options before your account falls too far behind.
Frequently Asked Questions
Is there a fee to pay my bill by phone?
No, Comcast does not charge a fee for paying your bill over the phone. The payment goes directly to your account with no additional cost.
Can I pay someone else's Comcast bill using this number?
You can pay another person's bill if you have their account number and permission. The automated system will process the payment to whichever account number you enter. If you want to set up regular payments for someone else's account, a representative can help you arrange that.
What if I do not have a debit or credit card?
You can pay from a bank account using your routing number and account number. If you do not have either a card or bank account, you can pay in person at a Comcast service center or by mailing a check to the address on your bill.
How long does it take for a phone payment to show up in my account?
Payments made before 11:59 p.m. Eastern Time typically post the same business day. You will receive a confirmation number when ready when you complete the call, but the payment may take a few hours to appear in your online account or app.
Can I cancel a payment after I have made it?
Once you receive a confirmation number, the payment has been processed and cannot be cancelled through the phone system. If you believe the payment was made in error, call back and speak to a representative, who can investigate and may be able to issue a credit or refund depending on the situation.
