Call Xfinity directly to start the cancellation process

To cancel Xfinity internet, you need to call Comcast's customer service line at 1-800-934-6489. Have your account number ready — you can find it on your bill or in the Xfinity app. The representative will confirm your identity, explain any early termination fees if you're under contract, and walk you through the cancellation steps.

Cancellation by phone is the only way Xfinity processes the request. You cannot cancel online, through the app, or by email. The call typically takes 10 to 15 minutes. The representative will ask why you're leaving and may offer discounts to keep your service — you can accept or decline.

Request a cancellation date that works for you. Xfinity usually processes cancellations within 24 to 48 hours of your call, though the service may stay active for a few more days. Ask the representative to email you a confirmation with your cancellation date and any final charges.

Key Takeaways

  • Call 1-800-934-6489 with your account number to start cancellation — this is the only method Xfinity accepts.
  • Check your contract for early termination fees, which can range from $0 to several hundred dollars depending on your plan and how much time remains.
  • Return all Xfinity equipment (modem, router, cable box) within 30 days to avoid equipment fees, usually $100 to $200 per item.
  • Request written confirmation of your cancellation date and final bill amount before you hang up.
  • Your final bill arrives within one to two billing cycles and includes any unreturned equipment charges.

Understand early termination fees before you call

If you signed a contract with Xfinity, canceling before the contract ends triggers an early termination fee. The amount depends on how much time is left on your agreement — typically $10 to $15 per month remaining, though some older contracts charge a flat fee of $120 to $240.

Check your contract terms by logging into your Xfinity account online or calling customer service. The representative can tell you the exact fee for your account. If you're month-to-month with no contract, there is no early termination fee — you can cancel anytime.

Some Xfinity promotions include contract terms buried in the fine print. If you signed up for a promotional rate, the contract may extend beyond the promotion period. Ask the representative whether your account has a contract before you commit to a cancellation date.

Return equipment within 30 days to avoid additional charges

Xfinity charges $100 to $200 per unreturned item. Most customers have a modem, a router, and possibly a cable box. You must return these within 30 days of your cancellation date, or the charges appear on your final bill.

When you call to cancel, ask the representative where to return equipment. Xfinity accepts returns at Comcast service centers, Best Buy locations, or by mail. If you choose mail, ask for a prepaid shipping label — some regions provide them, others do not. Keep the tracking number until Xfinity confirms receipt.

Wipe your personal information from the modem and router before returning them. These devices may retain your WiFi password and network settings. Factory reset both devices using the reset button on the back, held for 10 to 15 seconds until the lights flash.

Know what happens to your final bill

Your final bill arrives one to two billing cycles after cancellation and includes charges through your cancellation date, any early termination fee, and equipment return fees if applicable. Xfinity prorates your final month — if you cancel mid-month, you pay only for the days you used the service.

The final bill also shows any credits applied, such as promotional discounts that ended or service credits for outages. Review it carefully to catch billing errors. If you see a charge you don't recognize, contact Xfinity within 30 days to dispute it.

If you have autopay set up, Xfinity charges your final bill to the same payment method. You can change your payment method before cancellation if you prefer to pay by check or a different card.

Cancel bundled services separately if needed

If you have Xfinity internet bundled with TV or phone service, canceling internet does not automatically cancel the other services. When you call to cancel internet, tell the representative whether you want to keep TV or phone. If you keep them, your bill will change because you lose the bundle discount.

Some bundles require all services to stay active to maintain the promotional rate. If that applies to your account, canceling internet may raise the price of TV or phone. The representative will explain this before processing your cancellation.

If you want to cancel all services at once, say so during the call. The representative will process all three cancellations together and explain the total fees and final bill amount.

What to do if you cannot reach customer service

Xfinity's phone lines are busiest on weekday mornings and evenings. If you get a long wait, try calling early morning (before 9 a.m.) or late evening (after 8 p.m.). You can also try the Xfinity app — some regions allow you to request a callback from a representative, and they call you at a time you choose instead of making you wait on hold.

If you have an active service issue (no internet, frequent outages), mention it during the call. Xfinity sometimes waives early termination fees for customers with unresolved technical problems. Document any outages with screenshots or notes of the date and time before you call.

Keep your confirmation email and any reference numbers from your cancellation call. If Xfinity continues to bill you after your cancellation date, you have proof of when you canceled and can dispute the charges with your credit card company or bank.

Frequently Asked Questions

Can I cancel Xfinity internet without paying an early termination fee?

Only if you have no contract or your contract has ended. Check your account online or ask the representative during your cancellation call. If you have an active contract, the fee applies unless Xfinity waives it — which sometimes happens if you have unresolved service problems or if the representative offers it as a retention incentive.

What if I move and want to cancel instead of transferring service?

Moving does not waive early termination fees. However, if Xfinity service is not available at your new address, the company may waive the fee. Tell the representative your new address during the cancellation call, and they can check availability. If service is unavailable, ask them to note this in your account before processing the cancellation.

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

Billing stops on your cancellation date, though the service may remain active for a few days after. Your final bill arrives one to two billing cycles later. If Xfinity bills you after your cancellation date, contact them when ready with your confirmation email and reference number.

Do I have to return the equipment in person, or can I mail it?

You can do either. Ask the representative which option is available in your area. If you mail equipment, request a prepaid shipping label and keep the tracking number until Xfinity confirms receipt. In-person returns at Comcast service centers or Best Buy are usually faster.

What if I change my mind after canceling?

Contact Xfinity within a few days of your cancellation call. If the cancellation has not yet processed, the representative can reverse it. If it has processed, you can reactivate service, but you may lose any promotional rates you had before. Early termination fees do not explore to reactivation.
