How to cancel Comcast

Comcast requires you to call their customer service line to cancel — you cannot do it online or through the mail. The number is 1-800-934-6489. Have your account number ready, which appears on your bill or in the Xfinity app. The process takes about 15 to 20 minutes on the phone. Comcast will ask why you are leaving and may offer you a discount to stay; you can accept or decline. After you hang up, you will receive a confirmation email with your cancellation date, usually 7 to 30 days out depending on your service type and location.

If you rent equipment from Comcast — a modem, router, or TV box — you must return it. They will tell you during the call whether to drop it at a local Comcast store, mail it back, or schedule a pickup. If you do not return equipment, Comcast will charge you a non-return fee, typically $100 to $150 per device. Keep your confirmation email as proof of the cancellation date in case you are billed after that date.

Key Takeaways

  • Call 1-800-934-6489 with your account number to cancel; online cancellation is not available.
  • Comcast will offer discounts during the call, but you are not required to accept them.
  • You must return all rented equipment (modem, router, TV boxes) or face non-return fees of $100 to $150 per device.
  • Your cancellation takes effect 7 to 30 days after you call, and you will receive a confirmation email with the exact date.
  • Keep your confirmation email to dispute any charges that appear after your cancellation date.

What happens to your bill after cancellation

Comcast will prorate your final bill based on your cancellation date. If you cancel mid-month, you pay only for the days you used the service. Your final bill arrives by mail or email within 7 to 10 days of your cancellation date. If you have a balance owed — for example, if you damaged equipment or did not return it — Comcast will add that to your final bill.

If you paid in advance (for example, you prepaid for three months), Comcast will refund the unused portion. Refunds typically arrive within 7 to 14 business days to your original payment method. If you used a credit card, the refund goes back to that card. If you paid by check or bank transfer, contact Comcast to confirm where the refund will go.

Returning Comcast equipment

During your cancellation call, Comcast will tell you which equipment you must return and how. The most common options are: drop-off at a local Comcast store, mail it back in a prepaid box, or schedule a technician pickup. Drop-off is the fastest — you can do it the same day. Mail-back takes 5 to 10 business days. Pickup requires scheduling and may take 1 to 2 weeks depending on availability in your area.

Keep a photo or list of what you are returning. When you drop off or mail equipment, ask for a receipt or take a photo of the receipt. If you schedule a pickup, the technician will give you a receipt. Save this proof for at least 60 days. If Comcast later claims you did not return something, you can dispute the non-return fee with this documentation.

Avoiding early termination fees

Comcast charges an early termination fee if you cancel before your contract ends. The fee is typically $120 to $180, but it varies by region and service type. If you signed up for a promotional rate or bundled services, you likely have a contract term — usually 12 or 24 months. Check your bill or log into your Xfinity account to see your contract end date.

If you are still under contract, ask Comcast during your cancellation call whether the fee applies. Some situations waive the fee: if you are moving outside Comcast's service area, if Comcast is discontinuing service in your area, or if you have a documented service outage that lasted more than 24 hours. If you believe one of these applies to you, mention it during the call and ask them to review your account.

Cancelling internet only versus TV and phone bundles

If you have a bundle — internet, TV, and phone together — cancelling one service may change your bill for the others. Comcast often prices bundles lower than individual services. If you cancel TV but keep internet, your internet bill may go up because you lose the bundle discount. Ask Comcast what your new rate will be before you confirm the cancellation.

Some readers find it cheaper to keep a bundle and not use one service than to cancel it. For example, keeping a TV package you do not watch might cost less than paying full price for internet alone. During your cancellation call, ask Comcast to quote you the price for the services you want to keep. Compare that to your current bill before you decide what to cancel.

What to do if you cannot reach Comcast by phone

If you have tried calling 1-800-934-6489 multiple times and cannot get through, you have other options. You can contact Comcast through the Xfinity app by going to Account > Contact Us > Chat with an agent. Chat support can sometimes initiate a cancellation, though they may still transfer you to a phone agent to complete it. Response time for chat is usually 5 to 15 minutes during business hours.

You can also file a complaint with your state's public utilities commission or attorney general's office if Comcast refuses to cancel your service or charges you improperly. Include your account number, the date you called to cancel, and any confirmation emails or receipts. The complaint does not cancel your service, but it creates a record and may prompt Comcast to resolve billing disputes faster.

Switching to a new internet provider

Before you cancel Comcast, confirm that your new provider's service is active and working. Many providers offer a grace period — usually 7 to 14 days — where you can test their service and cancel if it does not work. Use that window to make sure you have internet before you disconnect from Comcast.

If your new provider requires you to return a modem or other equipment, coordinate the timing. You do not want to return Comcast equipment and then wait for your new provider's equipment to arrive with no internet in between. Some providers will ship equipment before your start date so you can set it up and test it while you still have Comcast.

Frequently Asked Questions

Can I cancel Comcast online or by email?

No. Comcast requires phone cancellation only. You must call 1-800-934-6489. The company does not accept cancellations through the Xfinity app, email, or online chat, though chat can sometimes help you reach a phone agent faster.

What if I owe money on my Comcast account?

You can still cancel. Comcast will add any balance owed to your final bill. If you dispute a charge, contact Comcast before you cancel to resolve it, or include the dispute in writing with your equipment return.

How long does it take for Comcast to stop billing me?

Billing stops on your cancellation date, which Comcast confirms in your email. If you are charged after that date, contact Comcast with your confirmation email and ask for a credit. Most disputes are resolved within 7 to 10 business days.

Do I have to pay an early termination fee?

Only if you are still under contract. Check your bill or Xfinity account for your contract end date. If you are moving outside Comcast's service area or have had a major service outage, mention this during your cancellation call — these situations sometimes waive the fee.

What if Comcast says I did not return equipment?

Provide your receipt or photo proof of the return. If you mailed it, ask Comcast for the tracking number and confirm delivery. If the dispute is not resolved, file a complaint with your state's attorney general or public utilities commission and include your proof of return.
