The main Comcast customer service number for bill payment is 1-800-934-6489
Call this number to pay your Xfinity bill over the phone using a debit card, credit card, or bank account. A representative will walk you through the payment and can answer questions about your account balance or due date while you are on the line. Wait times vary by time of day and season — calling early morning on a weekday usually means shorter holds than evening or weekend calls.
You do not need to speak to a representative if you prefer not to. Comcast's automated system lets you enter your account number and payment information using your phone keypad, which is faster if you know exactly what you want to pay. The automated system is available 24 hours a day.

What information you need before calling
Gather your Xfinity account number before you dial. You can find it on your bill, in the Xfinity My Account app, or on your account statement. If you are paying from a checking or savings account, have your routing number and account number ready. For credit or debit card payments, have the card number, expiration date, and CVV code available.
If you are paying someone else's bill or calling about a different account, you will need that account number instead. Comcast will ask for the last four digits of the phone number or service address associated with the account to verify you have permission to pay it.
How the automated payment system works
When you call 1-800-934-6489, the automated system will ask you to enter your account number using your phone keypad. It will then tell you your current balance and due date. You can choose to pay the full amount due, the minimum payment, or a custom amount. The system accepts debit cards, credit cards, and bank account transfers.
After you enter your payment information, the system will confirm the amount and the date the payment will post. Most payments made before 11:59 p.m. Eastern Time are processed the next business day. The system will give you a confirmation number — write this down or take a screenshot if you are using a mobile phone, in case you need to reference the payment later.
Speaking to a representative instead
If you want to discuss your bill, ask about a payment plan, or have questions the automated system cannot answer, press the option to speak to a representative. You may wait on hold, but a Comcast agent can help you understand charges, set up automatic payments, or work out an arrangement if you are behind on your bill.
Representatives can also process payments and may be able to note your account if you are working through a financial hardship. If you are calling about a disconnect notice or past-due account, speaking to a person rather than using the automated system often gives you more options.
Setting up automatic payments to avoid calling each month
If you call frequently to pay your bill, you can set up automatic payments so the charge happens on the same day each month without you having to dial. When you call 1-800-934-6489, ask the representative to enroll you in autopay. You can also set this up in the Xfinity My Account app or on the Comcast website without calling.
Automatic payments can come from a bank account or a credit or debit card. You choose the payment date and the amount — you can pay the full bill, a set dollar amount, or the minimum due. You can change or cancel autopay at any time, and Comcast will send you a reminder email before each payment goes through.
What to do if your payment does not post
Payments made by phone usually show up in your account within one business day. If more than two business days have passed and you do not see the charge reflected in your balance, call 1-800-934-6489 again and have your confirmation number ready. A representative can look up the payment and tell you its status.
If the payment was declined, the system will tell you immediately and ask you to try a different payment method. Common reasons for decline include an expired card, insufficient funds, or a mismatch between the address on file and the address you entered. If you are unsure why a payment was rejected, a representative can walk through the issue with you.
Other ways to pay if you prefer not to call
Paying by phone is one option, but Comcast offers several other methods. You can pay online through the Xfinity My Account app or website, set up automatic payments, mail a check to the address on your bill, or pay in person at a Comcast service center. Some areas also allow payment through third-party services like PayPal or third-party bill payment platforms.
Online and app payments are instant and available 24 hours a day. Mailed checks take five to seven business days to arrive and post. In-person payments at a service center are processed immediately but require you to visit during business hours. Choose the method that works best for your schedule and preferences.
Frequently Asked Questions
Is there a fee to pay my Comcast bill by phone?
No. Comcast does not charge a fee for paying by phone using a debit card or bank account. Credit card payments may carry a fee depending on your card issuer, but Comcast itself does not add a charge. Check with your credit card company if you are unsure whether they charge for bill payments.
Can I pay someone else's Comcast bill by phone?
Yes. You will need their account number and the last four digits of the phone number or service address on file. The automated system or a representative can process the payment. If you are a family member or authorized user on the account, you can pay without additional permission.
What time should I call to avoid a long wait?
Early morning on a weekday — between 8 a.m. and 10 a.m. — usually has shorter wait times than evening or weekend calls. If you use the automated system instead of waiting for a representative, you will not encounter a wait at all, and the system is available around the clock.
Can I set up a payment plan if I cannot pay my full bill?
Yes, but you need to speak to a representative. Call 1-800-934-6489 and ask to discuss your account. Representatives can work out arrangements for past-due balances or help you understand your options if you are facing a disconnect. Having this conversation before your account goes to collections gives you more flexibility.
How long does it take for a phone payment to show up on my bill?
Most payments post within one business day. If you pay before 11:59 p.m. Eastern Time on a weekday, it usually appears the next day. Payments made on weekends or holidays may take until the next business day to process. You will receive a confirmation number immediately when the payment is submitted.
