Contact Comcast directly to cancel your account

Comcast requires you to call to cancel — they do not process cancellations online or by email. Call 1-800-934-6489 and tell the representative you want to cancel your service. Have your account number ready (on your bill or in the Xfinity app). The call usually takes 10 to 20 minutes.

The representative will ask why you are leaving and may offer discounts or service changes to keep you as a customer. You can accept or decline. If you decline, they will schedule a final date for service to stop and arrange equipment return. Write down the cancellation date and confirmation number they give you.

Cancellation takes effect on the date you choose, not the date you call. Most people schedule it 7 to 14 days out to allow time to return equipment and make other arrangements. If you need service to stop immediately, tell the representative — they can usually process same-day cancellation, though you may still owe for the full billing cycle.

Key Takeaways

  • Call 1-800-934-6489 with your account number to start the cancellation process; Comcast does not cancel service by email or through their website.
  • The representative may offer discounts or service changes before processing the cancellation — you can accept or refuse.
  • You choose the cancellation date, which is usually 7 to 14 days after you call, and you will receive a confirmation number.
  • You must return all Comcast equipment (modem, router, cable box, remote) by the cancellation date or face equipment fees, typically $100 to $300 per item.
  • Your final bill will include charges through the cancellation date plus any unreturned equipment fees.

What equipment you need to return and when

Comcast will tell you during the cancellation call which equipment belongs to them and must be returned. This usually includes the modem, wireless router, cable box, and remote control. Some customers own their modem (if they bought it separately); if that is the case, you keep it.

The representative will give you a return deadline, typically 30 days after your service stops. You can return equipment at a Comcast store, by mail, or sometimes by scheduling a technician pickup. Comcast stores are usually located inside Xfinity retail locations. If you return by mail, Comcast will provide a prepaid shipping label — do not pay for shipping yourself.

If you do not return equipment by the deadline, Comcast charges a non-return fee for each item. These fees range from $100 to $300 per device. Check your final bill carefully; if you are charged for equipment you returned, contact Comcast with your receipt or tracking number to dispute the charge.

Understanding your final bill and any remaining charges

Your final bill will arrive within one to two billing cycles after cancellation and will include charges through your cancellation date. If you cancel mid-cycle, you pay only for the days you had service, not the full month. The bill will also list any equipment non-return fees if applicable.

Some customers have promotional rates that end when service cancels. If you are in a contract or have an active promotion, you may owe an early termination fee. Comcast will tell you the amount during the cancellation call. Early termination fees typically range from $0 to $120 depending on your plan and how long you have had service.

If your account has a credit balance (you overpaid or had a refund pending), Comcast will apply it to your final bill. If a credit remains after the final bill is paid, Comcast will mail you a check, usually within 4 to 6 weeks. If you owe money, you can pay online through your Xfinity account or by phone.

Cancelling internet-only service versus bundled plans

If you have internet only, cancellation is straightforward: you stop paying, return the modem and router, and service ends. If you have a bundle (internet, TV, and phone), you can cancel individual services or the entire account. Some customers cancel TV but keep internet, or cancel internet but keep phone service for 911 access.

When you cancel one service in a bundle, your remaining services may lose a promotional discount. For example, if you have a $50/month bundle and cancel TV, your internet rate might jump to $70/month because the discount applied only to the bundle. The representative will tell you the new rate before processing the cancellation.

If you have phone service through Comcast, cancelling it means you lose that phone number unless you port it to another provider. To keep your number, contact your new phone provider before you cancel Comcast and ask them to initiate a port-in. This usually takes 24 to 48 hours. Do not cancel Comcast phone service until the port is complete.

What to do if you have an outstanding balance or dispute

If your account has an unpaid balance, Comcast will ask you to settle it before processing cancellation. You can pay by phone during the cancellation call, online through your Xfinity account, or by mail. If you dispute a charge on your bill, tell the representative during the cancellation call — they can flag it for review, though the cancellation will still proceed.

If you believe you were overcharged or have a billing error, you can file a dispute after cancellation. Contact Comcast customer service at 1-800-934-6489 with your account number, the disputed charge, and an explanation. Comcast has 30 to 60 days to investigate. Keep copies of your bills and any correspondence.

If you cannot reach a resolution with Comcast directly, you can file a complaint with the Federal Communications Commission (FCC) at fcc.gov/consumers or by calling 1-888-225-5322. The FCC does not resolve billing disputes but will forward your complaint to Comcast, which must respond within 30 days.

Switching to a new internet or TV provider

Before you cancel Comcast, research and sign up with your new provider. Most providers take 5 to 10 business days to activate service after you order. If there is a gap between when Comcast stops and your new provider starts, you will have no internet or TV during that time. Schedule your Comcast cancellation date to overlap with your new provider's start date.

If your new provider requires installation, schedule that appointment before you cancel Comcast. Technicians usually need access to your home for 1 to 3 hours. Once your new service is confirmed working, you can safely cancel Comcast without risk of losing connectivity.

Some areas have limited provider options. If you are moving to a location with only one internet provider, confirm that provider is available at your new address before you cancel Comcast. Use the provider's address lookup tool on their website, or call them directly with your address.

Frequently Asked Questions

Can I cancel Comcast online or through the app?

No. Comcast requires cancellation by phone at 1-800-934-6489. You cannot cancel through the Xfinity website, app, or email. The phone call ensures the representative can discuss your account, offer retention options, and confirm your cancellation date and equipment return instructions.

What happens if I don't return equipment by the deadline?

Comcast charges a non-return fee for each unreturned item, typically $100 to $300 per device. These fees appear on your final bill. If you return equipment late but within a reasonable time, contact Comcast with proof of return (tracking number or receipt) to request a fee waiver.

Do I owe anything if I cancel before my contract ends?

It depends on your plan. Some Comcast plans have no contract; others have a 12 or 24-month term with an early termination fee if you cancel before it ends. The representative will tell you the fee amount during your cancellation call. Fees typically range from $0 to $120.

How long does it take to process a cancellation?

Service stops on the date you choose during the cancellation call, usually 7 to 14 days after you call. Your final bill arrives within one to two billing cycles. Equipment return deadlines are typically 30 days after service stops.

What if I want to cancel only one service in my bundle?

Call 1-800-934-6489 and tell the representative which service you want to cancel. Your remaining services may lose a promotional discount, so ask for the new rate before confirming. If you are cancelling phone service, port your number to your new provider first to avoid losing it.
