Call Comcast to request cancellation

To cancel Comcast service, call 1-800-934-6489 and tell the representative you want to end your account. Have your account number ready — you'll find it on your bill or in the Comcast app. The representative will confirm your service address and ask why you're leaving, but you don't have to explain.

Comcast will tell you the cancellation date (usually within 7 to 10 days of your call) and what you owe for the remainder of your billing cycle. If you're under a contract, they may mention an early termination fee — this is negotiable, and some representatives will waive it if you ask. Write down the cancellation date and confirmation number before you hang up.

Do not rely on chat or email to cancel. Comcast's phone line is the only method that creates a documented record of your request. Chat and email requests often get lost or delayed, and you may be charged for service you thought you'd ended.

Key Takeaways

  • Call 1-800-934-6489 with your account number ready; this is the only reliable way to cancel and creates a record of your request.
  • Comcast will set a cancellation date within 7 to 10 days and tell you what final charges you owe.
  • Early termination fees are common if you're under contract, but you can ask the representative to waive them.
  • Return all equipment — modem, router, cable box — to a Comcast store or by mail to avoid equipment fees.
  • Request a final bill in writing and keep your confirmation number until you receive it.

What happens to your final bill

Comcast will charge you through the cancellation date. If you cancel mid-cycle, you'll pay a prorated amount for the days you used service that month. You'll also be charged for any unreturned equipment — modems typically cost $100 to $200, routers $50 to $100, and cable boxes $20 to $50 each.

Ask the representative during your cancellation call whether you can return equipment by mail or if you need to visit a store. Comcast has retail locations in most areas, but mail return is faster if you have a printer to generate a shipping label. Keep the tracking number until Comcast confirms receipt.

Your final bill arrives 2 to 4 weeks after cancellation. If you're owed a refund for overpayment or a service credit, Comcast will include it on that bill or mail a separate check. Do not assume the cancellation is complete until you receive and review the final bill.

Early termination fees and contract obligations

If you signed a contract with Comcast, canceling before the end date triggers an early termination fee. This fee ranges from $100 to $240 depending on your contract length and how much time remains. Comcast will calculate this during your cancellation call.

You can ask the representative to reduce or remove the fee, especially if you've been a customer for several years or if you're moving to an area without Comcast service. Some representatives have authority to waive the fee; others will transfer you to a retention specialist who does. It costs nothing to ask, and the worst outcome is they say no.

If you're moving and Comcast serves your new address, you can transfer your service instead of canceling. This avoids the early termination fee and may may have access to you for a new-customer promotion. Ask the representative whether this option is available before you finalize cancellation.

Returning equipment and avoiding extra charges

Comcast equipment must be returned within 30 days of your cancellation date, or you'll be charged a non-return fee for each item. The easiest method is to visit a Comcast store — staff will scan the equipment and give you a receipt. Keep this receipt as proof of return.

If you mail equipment back, Comcast will provide a prepaid shipping label when you call to cancel. Print the label, pack the modem, router, and cable boxes in a box, and drop it at any UPS location. Take a photo of the package before you ship it and save the tracking number. Comcast's system can take 2 to 3 weeks to register the return, so don't assume it's received until you see the charge removed from your account.

Some Comcast locations also have drop-off kiosks in lobbies or parking lots. These are faster than waiting in line, but you won't get a receipt. If you use a kiosk, photograph the equipment before you drop it off and note the time and location.

What to do if Comcast continues charging you

After your cancellation date passes, check your credit card or bank account to make sure Comcast stops charging you. If charges appear after the cancellation date, call 1-800-934-6489 again and reference your original confirmation number. Ask to speak with a supervisor if the representative can't immediately stop the charges.

If Comcast refuses to remove the charges, file a complaint with your state's attorney general or with the Federal Communications Commission (FCC). The FCC has a complaint form at fcc.gov/consumers. Include your confirmation number, the dates you were incorrectly charged, and copies of your bills. The FCC will forward your complaint to Comcast, which must respond within 30 days.

You can also dispute the charges with your credit card company or bank. Most will reverse unauthorized charges within 30 to 60 days while they investigate. Do this in parallel with contacting Comcast — it doesn't prevent Comcast from fixing the error, and it protects your account if they don't.

Switching to another internet provider

Before you cancel Comcast, confirm that your new provider's service is active and working. Many people cancel too early and end up without internet for days. Schedule your new provider's installation for the same day as your Comcast cancellation or a day after.

If you own your modem and router, you can use them with most other providers — but check compatibility first. Comcast-branded equipment (Xfinity modems) usually won't work with other providers. If you're renting from Comcast, you'll need to return it anyway, so you'll need new equipment from your next provider.

Some providers offer credits or discounts if you're switching from Comcast. Ask about this when you sign up with the new provider — you may be able to offset part of any early termination fee Comcast charges.

Frequently Asked Questions

Can I cancel Comcast online or through the app?

Comcast's website and app don't have a cancellation option. You must call 1-800-934-6489. Online chat can start the process, but it won't complete the cancellation — a representative will call you back to finish it. Calling directly is faster and creates a clear record.

What if I'm moving and Comcast doesn't serve my new address?

Tell the representative your new address during the cancellation call. If Comcast doesn't serve that area, they'll waive the early termination fee. You'll still pay for service through your cancellation date and any unreturned equipment, but the contract fee disappears.

How long does it take to cancel?

The phone call takes 10 to 20 minutes. Your service ends within 7 to 10 days. Your final bill arrives 2 to 4 weeks after that. The entire process from call to final bill is typically 4 to 6 weeks.

Will Comcast try to keep me as a customer?

Yes. After you request cancellation, a retention specialist may call or email with discounts or service upgrades. You can accept an offer if you want to stay, or you can decline and proceed with cancellation. Declining doesn't change your cancellation date — it only stops if you explicitly ask the representative to reverse it.

What if I rented my modem but didn't know it?

You'll find out during the cancellation call. The representative will tell you which equipment is rented and which you own. Return all rented equipment within 30 days to avoid fees. If you've already lost or damaged equipment, ask about the replacement cost — sometimes it's less than the non-return fee.
