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 and use the automated system. You will need your account number (on your bill or in the My Account app) and a debit card or bank account information. The system accepts payments when ready and does not charge a fee for this method.
The automated line operates 24 hours a day, seven days a week. You do not need to speak to a representative unless something goes wrong — the system will walk you through each step and confirm your payment before processing it. If you prefer to speak with someone, you can stay on the line after the automated greeting and ask to be transferred to a billing representative.
Payments made before 11:59 p.m. Eastern Time typically post to your account the same day. If you call after that time, the payment will usually post the next business day. The system will give you a confirmation number — write it down in case you need to reference the payment later.

What information you need to have ready
Before you call, gather your account number, which appears on your bill or in the My Account app. You will also need a valid debit card or bank account to pay with — Comcast does not accept credit cards over the phone for security reasons. Have the card or account details in front of you so you can enter them quickly.
If you do not have your account number handy, the system can look it up using your phone number or service address. This takes a bit longer but works if you cannot locate your bill. If you are calling about a past-due account or a collection notice, have that document nearby so you can reference the exact amount owed.
Paying with a debit card versus bank account
Both payment methods work the same way over the phone and carry no fee. A debit card is faster if you want the payment to post when ready — the system processes it right away. A bank account (checking or savings) can take one to two business days to post, but some people prefer it because they do not have to enter card details.
Neither method charges you extra. Comcast does not add a convenience fee for phone payments the way some companies do for online or credit card transactions. The amount you authorize is the amount that will be deducted.
What to do if the automated system does not work
If the automated system rejects your card or account information, try entering it again — sometimes a typo causes the system to decline. If it fails a second time, press the button to speak with a representative. They can process the payment manually and may be able to tell you why the automated system rejected your first attempt.
If you are calling from outside the United States, the automated system may not recognize your number. Call the same number and ask to be transferred to a representative who can help you pay from an international line. Some international calls may incur long-distance charges depending on your phone plan.
Paying a past-due or collection account
If your account is past due or has been sent to a collection agency, you can still pay by phone, but the process may be slightly different. Call 1-800-934-6489 and tell the system or representative that you are paying a past-due balance. Have the collection notice or past-due letter in front of you so you can provide the exact amount owed.
Some past-due accounts require you to speak with a representative rather than use the automated system. If the automated system does not recognize your account as past due, press the button to transfer to a representative. They can confirm the amount owed and process the payment right away. Ask for a confirmation number and the date the payment will post.
Other ways to pay if you cannot call
If calling does not work for you, Comcast offers other payment methods. You can pay online through the My Account app or website, set up automatic payments from your bank account, mail a check to the address on your bill, or pay in person at a Comcast service center. Each method has different posting times — online payments usually post within one business day, while mailed checks can take five to seven business days.
Automatic payments are useful if you want to avoid calling every month. You can set them up through the My Account app or by calling a representative and asking them to enroll you. You can change or cancel automatic payments at any time through the app or by calling back.
Frequently Asked Questions
Does Comcast charge a fee to pay by phone?
No. Comcast does not charge a fee for phone payments made through the automated system or with a representative. The amount you authorize is the amount deducted from your account.
How long does it take for a phone payment to show up on my bill?
Debit card payments usually post the same day if you call before 11:59 p.m. Eastern Time. Bank account payments can take one to two business days. You will receive a confirmation number when ready after you authorize the payment.
Can I pay someone else's Comcast bill by phone?
Yes, but you will need their account number or service address. The system will ask for this information to locate the account. If you do not have it, you can provide the account holder's name and phone number, and the system will look it up for you.
What if I want to set up a payment plan instead of paying the full amount now?
The automated phone system handles one-time payments only. To discuss a payment plan for a past-due balance, press the button to speak with a representative. They can work out an arrangement based on your situation.
Is the phone payment system find?
Yes. Comcast's automated system uses encryption to protect your payment information. The system does not store your full card or account number after the transaction completes. If you are concerned about security, you can speak with a representative instead of using the automated system.
