Comcast's main customer service number is 1-800-934-6489
This number connects you to Comcast's general customer service line, where representatives handle billing questions, service issues, account changes, and technical support. The line operates seven days a week. Wait times vary by time of day — early morning and late evening typically have shorter queues than midday.
When you call, have your account number ready. You can find it on your bill or in the Comcast app. The system will ask you to verify your phone number or account number before routing you to the right department. If you know which department you need, you can often skip the initial menu by saying it aloud — the automated system recognizes common requests like "billing" or "technical support."

What to expect when you call
After you dial 1-800-934-6489, an automated system will greet you and ask why you're calling. You can respond by speaking naturally — say "I need to report an outage" or "I have a billing question" — and the system will route you accordingly. If you prefer, you can also press numbers on your keypad to navigate the menu.
Once you reach a representative, they'll verify your identity using your account number, phone number, or the last four digits of the Social Security number on file. This step takes a few minutes but prevents unauthorized changes to your account. After verification, the representative can address your issue, whether that's troubleshooting a modem, discussing your bill, or scheduling a technician visit.
If you're calling about a technical problem, the representative may ask you to restart your equipment or check cable connections. Have your modem and router nearby so you can follow along. If the issue can't be resolved over the phone, they'll schedule a technician to visit your home — usually within one to three business days depending on your area.
Department-specific numbers and when to use them
While 1-800-934-6489 handles most issues, Comcast publishes separate numbers for specific situations. If you're a Comcast Business customer (not residential), call 1-866-405-5000. This line connects you to business account specialists who handle different policies and service levels than residential support.
For billing disputes or to discuss your account, the general number routes you to the billing department. For internet or phone service problems, you'll reach technical support. For TV-related issues, you'll speak with someone in the video services team. You don't need to memorize separate numbers — the main line 1-800-934-6489 handles all of these by routing your call internally.
If you're calling about a service outage in your area, the system often recognizes this and provides estimated restoration times without requiring you to speak to a representative. You can also check outage status on the Xfinity app or website before calling.
Alternatives to calling if phone lines are busy
Comcast offers support through multiple channels beyond phone. The Xfinity app, available on iOS and Android, includes live chat with representatives during business hours. Chat typically has shorter wait times than phone lines during peak hours. You can also message through the app to report issues or ask questions without waiting on hold.
The Comcast website at xfinity.com has a support section where you can browse answers to common questions, restart your equipment remotely, or schedule a callback. The callback feature lets you request a call from a representative at a time that works for you, rather than waiting on hold when ready.
For billing questions, you can also log into your Xfinity account online to view your bill, make a payment, or change your service plan without speaking to anyone. Many account changes — like adding a service, pausing service temporarily, or updating your contact information — can be completed through the app or website in minutes.
Preparing for your call
Before you dial 1-800-934-6489, gather a few pieces of information. Your account number appears on your bill and in the Xfinity app. If you're calling about a technical issue, note what's happening — for example, "internet is down" or "phone calls won't connect." If you're calling about billing, have your bill in front of you so you can reference specific charges.
Write down what you want to accomplish before calling. If you have multiple issues, mention them all at once rather than calling back separately. Representatives can often handle several problems in one call, which saves you time on hold. If a representative can't resolve your issue, ask them to note it in your account so the next representative you speak with has context.
What to do if you can't reach anyone
If you're on hold for an extended time, you have options. Hang up and try again during off-peak hours — early morning between 7 and 9 a.m. or late evening after 8 p.m. typically have shorter waits. You can also use the callback feature on the website or app to request a call instead of waiting on hold.
If you're experiencing a service outage, check the Xfinity app or website first. The system often provides an estimated restoration time without requiring a call. If the outage is widespread in your area, Comcast's system may automatically credit your account for the downtime, so calling may not be necessary.
For billing disputes or complaints that aren't resolved by a representative, Comcast has a formal complaint process. You can file a complaint through your state's public utilities commission or through the Federal Communications Commission. These agencies investigate disputes and can compel Comcast to respond formally.
Frequently Asked Questions
Is there a way to skip the automated menu and talk to a person right away?
Not directly, but you can speed up the process. When the automated system asks why you're calling, respond clearly with your issue — "billing question" or "technical support" — and it will route you faster. Some callers report that saying "representative" or staying silent works, but this varies by system version.
What if I'm calling about an outage?
The automated system recognizes outage-related calls and often provides an estimated restoration time without connecting you to a representative. Check the Xfinity app or website first — they usually show outage status and timing. If you need to report an outage that isn't showing in the system, the automated line will connect you to someone who can log it.
Can I reach Comcast support outside the United States?
1-800-934-6489 is a U.S. number and won't work from outside the country. If you're traveling or living abroad, use the Xfinity app or website to contact support through chat or email. International customers should check their account for region-specific support numbers.
What if I'm on the phone with a representative and we get disconnected?
Call back and have your account number ready. Tell the new representative you were just speaking with someone about a specific issue — they can pull up your account notes and see what was being discussed. Provide the representative's name if you have it, though the account notes usually contain enough detail to continue where you left off.
Does Comcast charge for customer service calls?
No, calling 1-800-934-6489 is free. There are no charges for reaching customer service, regardless of how long you're on hold or how many calls you make. Some third-party services claim to offer "faster" Comcast support for a fee — these are not affiliated with Comcast and should be avoided.
