The phone number to pay your Comcast bill is 1-800-934-6489
Call that number and follow the prompts to pay over the phone using a debit card, credit card, or bank account. The system accepts payments 24 hours a day, 7 days a week. You will need your account number, which appears on your bill or in the Xfinity app, and your payment method ready before you call.
If you reach a representative instead of the automated system, they can also process your payment. The call is free — Comcast does not charge a fee for phone payments, though your bank may charge a fee if you use a debit or credit card.

What information you need before calling
Have your account number ready. It is printed on your bill in the upper right corner, or you can find it in the Xfinity app under Account. The automated system will ask for it to pull up your account and show your balance.
You will also need your payment method — either a credit card, debit card, or bank account number and routing number. The system will ask which you prefer and guide you through entering the information. If you use a bank account, have a voided check handy so you can read the routing number and account number accurately.
If you are paying someone else's bill or do not have the account number, a representative can help you. Stay on the line after the automated prompts end, or say "representative" or "agent" to skip the automated system and speak to someone directly.
When your payment will show up
Payments made before 11:59 p.m. Eastern Time usually post to your account the same day. Payments made after that time or on weekends may not appear until the next business day. The system will tell you the expected posting date after you confirm your payment.
If you are paying to avoid a service interruption, call as early in the day as possible. Comcast typically processes disconnections in the afternoon, so a morning payment gives you the best chance of stopping a shut-off the same day. If your service has already been disconnected, the same phone number can reconnect you once payment clears.
Alternatives to paying by phone
If you prefer not to call, you can pay online through the Xfinity website or app, by mail, or in person at a Comcast store. Online and app payments post the same day if made before 11:59 p.m. Eastern Time. Mail payments take 7 to 10 business days to arrive and post, so do not use mail if your bill is due soon.
You can also set up automatic payments so your bill is paid from your bank account or card each month without calling. Log into your Xfinity account online, go to Billing, and select "Automatic Payment." This removes the need to remember to pay and ensures you never miss a due date.
What to do if you cannot pay the full amount
If you cannot pay your full balance, call 1-800-934-6489 and ask to speak to a representative about a payment plan or extension. Comcast offers short-term extensions (usually 10 to 15 days) and longer payment plans that spread your balance over multiple months. You will need to make at least a partial payment to set up a plan in most cases.
Tell the representative your situation honestly — job loss, medical emergency, or temporary hardship. They have more flexibility than the automated system and may be able to pause late fees or prevent disconnection while you arrange a plan. If you are struggling with bills across multiple utilities, ask whether Comcast has a hardship program in your area.
Troubleshooting common payment problems
If your payment is declined, the system will tell you why — usually an expired card, incorrect information, or insufficient funds. Correct the information and try again, or use a different payment method. If the same card keeps failing, call a representative to troubleshoot or pay with a different card or bank account.
If you paid but your account still shows past due, wait until the next business day for the payment to post. If it has been more than one business day, call 1-800-934-6489 to confirm the payment went through. Occasionally a payment fails silently, and a representative can see what happened and reprocess it if needed.
Frequently Asked Questions
Is there a fee to pay by phone?
Comcast does not charge a fee for phone payments. However, your credit card company or bank may charge a fee for processing a payment over the phone — check your card's terms or call your bank to ask.
Can I pay someone else's Comcast bill?
Yes. Call 1-800-934-6489 and tell the representative you are paying on someone else's account. They will ask for the account number and may ask security questions to confirm you are authorized to pay. You can also pay online if you have the account number and the account holder's name.
What if I pay late but before disconnection?
Late fees apply once your bill passes the due date, even if you pay before your service is shut off. Call a representative to ask whether they will waive the late fee if you pay immediately — they sometimes do for first-time late payments or hardship situations, but it is not may provide.
Can I set up a payment plan over the phone?
Yes. Call 1-800-934-6489 and ask a representative about a payment plan. They will discuss how much you can pay now and how to split the remaining balance over future months. Most plans require a partial payment to start.
What happens if my payment fails and I do not notice?
Your account will show past due, and late fees will accrue. Comcast will send you a past-due notice by mail and may send text or email alerts if you have those set up. If you do not pay within 30 to 60 days, your service may be disconnected. Check your account online or in the app regularly to catch payment failures early.
