The phone number to pay your Comcast bill
Call 1-800-COMCAST (1-800-266-2278) to pay your bill by phone. This is Comcast's main customer service line, and it routes to bill payment representatives during business hours. You can pay with a debit card, credit card, or bank account.
The automated system will ask for your account number (found on your bill) and the amount you want to pay. If you prefer to speak with a representative instead of using the automated system, you can stay on the line after the initial prompts and request a transfer.
Comcast's phone lines are typically open seven days a week, though wait times are usually shorter on weekday mornings. If you call during off-hours, you can leave a callback request and a representative will contact you the next business day.

What information you need before calling
Have your Comcast account number ready before you dial. This number appears on your bill, usually near the top or in the account section. If you do not have your bill in front of you, you can look up your account number on the Comcast website by logging into your account.
You will also need to know the exact amount you want to pay. This might be your full bill balance, a partial payment, or a past-due amount. The representative or automated system will confirm the amount before processing the payment.
If you are paying from a bank account, have your routing number and account number available. For credit or debit card payments, have the card number, expiration date, and CVV code ready.
How payment by phone works
When you call, the automated system will walk you through the payment process step by step. It will ask you to enter your account number using your phone keypad, then confirm the amount you want to pay and your payment method.
The system processes the payment when ready and provides a confirmation number. Write down this number for your records — it serves as proof that you made the payment. The confirmation number also helps if you need to dispute the transaction later or if there is a question about when the payment posted.
The payment itself typically appears in Comcast's system within one to two business days. During that time, your account may still show as past-due, but the payment is in the queue. If your service was disconnected, it usually reconnects within 24 hours of the payment posting.
When to use phone payment versus other methods
Phone payment works best if you do not have internet access, prefer not to set up an online account, or need to speak with someone about your bill. It is also useful if you want to make a one-time payment without creating a recurring autopay arrangement.
If you need to set up automatic monthly payments, the Comcast website or mobile app is faster and does not require a phone call. If you want to mail a check, Comcast provides a mailing address on your bill, though mail payments take longer to process.
For questions about your bill itself — such as why a charge appears or whether you may have access to for a lower rate — a phone representative can often help during the same call. This makes phone payment useful when you have billing questions alongside the payment itself.
What to do if you cannot reach a representative
If wait times are long, you have two options: use the automated system to pay when ready, or request a callback. The callback option lets you stay in the queue without holding, and a representative will call you back within a set timeframe, usually the same business day.
If you reach Comcast's phone lines during off-hours (typically after 8 p.m. or before 8 a.m., depending on your region), the automated system is still available for payments. You can pay through the automated system at any time without waiting for business hours.
If you experience repeated trouble reaching Comcast by phone, the website or mobile app provides an alternative way to pay without calling. You can also visit a local Comcast service center in person if one is near you, though this requires a trip and may have limited hours.
Payment methods and fees
Comcast accepts credit cards, debit cards, and bank account payments by phone at no extra charge. There is no fee for paying by phone, regardless of which payment method you choose.
If you pay with a credit card, the payment posts as a transaction from Comcast, and your credit card company may charge you interest if you carry a balance. Paying from a bank account is often faster and does not incur interest, since the money moves directly from your checking or savings account.
Some people use prepaid cards or gift cards to pay bills by phone. Comcast's system will accept these as long as they have a Visa, Mastercard, American Express, or Discover logo. However, prepaid cards may have daily spending limits that could prevent a large payment from going through.
Frequently Asked Questions
Can I pay my Comcast bill by phone if I am behind on payments?
Yes. Comcast accepts phone payments even if your account is past-due or your service has been disconnected. In fact, paying by phone is often the fastest way to restore service if you have been disconnected. Once your payment posts, service typically reconnects within 24 hours.
How long does it take for a phone payment to show up on my account?
Phone payments usually appear in Comcast's system within one to two business days. Payments made on weekends or holidays may take until the next business day to process. You will receive a confirmation number when ready when you make the payment, even if it has not posted yet.
What if I made a payment by phone but my bill still shows as due?
This is normal during the one to two business days it takes for the payment to post. Check your confirmation number and the amount you paid to make sure they are correct. If more than two business days have passed and the payment still has not appeared, call Comcast again with your confirmation number to investigate.
Can I set up automatic bill pay when I call to make a payment?
Yes. When you call 1-800-COMCAST, a representative can set up autopay for you during the same call. You can choose to pay your full bill or a set amount each month, and you can cancel autopay at any time by calling back or logging into your online account.
Is it safe to give my bank account number to Comcast over the phone?
Comcast's phone payment system is encrypted and designed to protect your financial information. However, if you are uncomfortable providing your bank account number over the phone, you can use a credit or debit card instead, or pay through the website or mobile app.
