The main Comcast Xfinity customer service number is 1-800-934-6489
This number connects you to Comcast's general customer service line for billing questions, service issues, account changes, and technical support. Wait times vary by time of day and call volume, but calling before 10 a.m. on a weekday typically means shorter queues.
Comcast routes calls based on what you need. When you call, the automated system will ask whether you're calling about internet, TV, phone service, or billing. Selecting the right category gets you to the right department faster. If you're unsure which category fits your issue, choosing "billing" or "account services" usually works as a catch-all.
You can also reach Comcast through their website at xfinity.com or through the Xfinity mobile app, which often shows wait times before you call and lets you schedule a callback instead of holding.

Specialized phone numbers for different issues
While 1-800-934-6489 works for most questions, Comcast maintains separate lines for specific needs. The billing and payment line is 1-800-391-3000. Technical support for internet and TV problems also uses 1-800-391-3000. For Xfinity Mobile phone service, call 1-888-936-4639.
These numbers are not always faster than the main line, but they route you directly to the right team without the initial menu system. Your bill or account page online will list the most current numbers for your specific service type, since Comcast changes these periodically.
If you have a business account rather than a residential one, Comcast Business uses a different number: 1-866-429-3085. Business accounts have separate support hours and different service level agreements than residential service.
When to call versus using online options
Phone support is fastest for urgent problems — a service outage, a billing dispute you need resolved today, or a technical issue that online troubleshooting hasn't fixed. It's also the right choice if you need to make changes to your account that require verification, like adding a service or changing your billing address.
For non-urgent questions, the Xfinity website and app are often faster. You can check your bill, make a payment, restart your modem, or view your service status without waiting. The app shows real-time outage maps and lets you troubleshoot internet speed problems step by step. If you need to schedule a technician visit, the app and website let you pick your own time slot instead of waiting for a phone representative to find an opening.
Chat support through xfinity.com is also available during business hours and often has shorter wait times than phone lines, though it moves more slowly than a phone conversation.
What to have ready before you call
Comcast's automated system will ask for your account number or the phone number associated with your account. Having this information ready before you call cuts 2 to 3 minutes off your wait time. Your account number appears on your bill, in the Xfinity app, or on your account page at xfinity.com.
If you're calling about a technical problem, have your modem and router model numbers available. You can find these on the devices themselves or in the Xfinity app under "My Equipment." If you're calling about billing, have your recent bill in front of you so you can reference specific charges or dates.
If you're calling to dispute a charge or discuss a service issue, write down the dates and details before you call. This helps you explain the problem clearly and gives the representative specific information to look up in your account history.
International calling and TTY relay service
If you're calling from outside the United States, you can reach Comcast at +1-215-286-1700. This is a long-distance number, so charges may explore depending on your phone plan. The wait times and routing are the same as the domestic number.
Comcast provides TTY relay service for customers who are deaf or hard of hearing. Call 711 to connect to your state's relay service, then ask to be connected to Comcast at 1-800-934-6489. The relay service is free and available 24 hours a day.
Callback options and scheduling
Instead of waiting on hold, you can request a callback through the Xfinity app or website. When you select this option, Comcast calls you back when a representative is available, usually within a few hours. This is especially useful during peak times like evenings or weekends when hold times exceed 30 minutes.
To schedule a callback, open the Xfinity app, go to "Support," and select "Contact Us." Choose "Callback" instead of "Call Now." You'll see an estimated wait time and can choose whether you want the call today or at a specific time tomorrow. Comcast will call the number associated with your account unless you specify a different number.
Frequently Asked Questions
What time should I call to avoid long wait times?
Early mornings on weekdays — between 8 a.m. and 10 a.m. — typically have the shortest wait times. Evenings after 6 p.m. and weekends are usually busier. If you call during peak hours, the callback option through the app is faster than holding.
Can I reach Comcast through social media?
Yes. Comcast has customer service teams on Twitter (@ComcastCares) and Facebook. Response times are usually 1 to 2 hours during business hours. This works well for billing questions or general inquiries but not for urgent technical issues.
What if I'm having an outage and can't reach anyone?
Check the Xfinity app or website first — they show real-time outage maps and estimated restoration times. If an outage is affecting your area, you don't need to call. If your service is out but no outage is listed, restart your modem by unplugging it for 30 seconds. If that doesn't work, call 1-800-934-6489 and select the technical support option.
Do I need to stay on the phone with a technician during a service visit?
No. When you schedule a technician visit through the app or website, you can choose a time window and the technician will arrive during that window. You don't need to call back or stay on the phone. The app will send you a notification when the technician is on the way.
Is there a number for billing disputes or complaints?
Call 1-800-391-3000 for billing questions. If you have a formal complaint about service or billing that you want documented, ask to speak with a supervisor or manager. You can also file a complaint with your state's public utilities commission, which has authority over cable providers.
