The main Comcast Xfinity customer service number is 1-800-934-6489

This number connects you to Comcast's general customer service line, where you can ask about your bill, service issues, account changes, or technical problems. The line operates 24 hours a day, 7 days a week. When you call, you'll reach an automated system first that asks what you need — answering clearly ("billing" or "technical support") usually routes you faster than waiting for a representative.

Comcast also runs separate lines for specific needs. If you're calling about internet, TV, or phone service problems, the same 1-800-934-6489 number handles all three. If you're a new customer interested in signing up, Comcast directs those calls to 1-800-391-3000, though you can also start online at xfinity.com.

What to have ready before you call

Gather your account number before dialing. You'll find it on your Comcast bill, in the top right corner of the first page. If you don't have a bill handy, the automated system can look up your account using your phone number or service address instead, though this takes longer.

If you're calling about a technical problem, note what's not working: whether it's internet speed, TV channels, phone service, or all three. If your internet is down, write down what lights are on or off on your modem and router — the representative will ask. For billing questions, have your recent bill or a description of the charge you're asking about.

Faster alternatives to calling

Comcast's website chat feature at xfinity.com often has shorter wait times than the phone line, especially during peak hours. You can start a chat without logging in, and representatives can usually handle billing questions, service changes, and straightforward troubleshooting without transferring you. Chat is available during business hours, typically 8 a.m. to 11 p.m. Eastern time daily.

The Xfinity mobile app (available on iOS and Android) lets you pay your bill, check your data usage, restart your modem, and report outages directly. Many account changes — like adding a service or changing your plan — can be done through the app without speaking to anyone. The app also shows real-time outage information for your area, which the phone line's automated system provides but takes longer to reach.

When you're experiencing an outage

If your service is down, call 1-800-934-6489 and listen to the automated menu. Select the option for technical support or service outages. The system checks your address and tells you whether Comcast has detected an outage in your area, when they expect to restore service, and how many customers are affected. This information comes through without waiting for a representative.

If the automated system says there's no outage but your service is still down, that usually means the problem is with your equipment or your line specifically. The system will offer to schedule a technician visit or transfer you to technical support. Scheduling online through the app or website is faster than waiting on the phone, and you can often pick a same-day or next-day appointment.

Billing and account changes

For questions about your bill, charges, or your monthly rate, call the main number and select billing from the menu. Have your account number and your bill ready. Representatives can explain individual charges, discuss autopay options, and sometimes offer promotions if your rate has increased. Billing questions are often resolved faster through chat than by phone.

If you want to change your service — adding HBO, upgrading internet speed, or removing a service — you can do this through the app, website, or phone. Online and app changes take effect when ready. Phone changes may take 24 hours to process. Comcast sometimes offers better rates for changes made online, so check xfinity.com first before calling.

Reaching Comcast for specific situations

If you're moving and need to transfer your service, call 1-800-934-6489 or use the app. You'll need your new address and the date you want service to start. Comcast can usually transfer service within a few days if the new address is already wired for their network; if not, a technician visit may be needed.

If you're having trouble paying your bill or facing service disconnection, ask to speak with a representative about payment arrangements or hardship programs. Comcast has programs for customers facing financial difficulty, though these are not advertised on the main line — you have to ask. Be direct: "I'm having trouble paying my bill. Do you have payment plans or hardship programs?"

Frequently Asked Questions

How long is the typical wait time to speak with someone?

Wait times vary by time of day and day of week. Weekday mornings (9 a.m. to noon Eastern) typically have waits of 5 to 15 minutes. Evenings and weekends often have waits of 30 minutes or longer. Chat and the mobile app usually have shorter waits than the phone line.

Can I reach Comcast through social media?

Yes. Comcast monitors its Twitter account (@ComcastCares) and Facebook page for customer service messages. Response times are often faster than calling, especially for billing questions. Send a direct message with your account number and issue, and a representative will contact you.

What if I'm calling about a bill I don't recognize?

Call 1-800-934-6489 and select billing. Have your bill ready and describe the charge. Representatives can explain what each line item is for and sometimes reverse charges if there's been an error. Disputes over charges can take 30 to 60 days to resolve, so ask for a reference number.

Is there a number for Comcast business customers?

Yes. Comcast Business has a separate line: 1-800-391-3000. If you have a business account and call the residential number by mistake, the system will transfer you, but calling the business line directly is faster.

What should I do if I can't reach anyone after waiting a long time?

Try calling back during a different time of day, use the chat feature on xfinity.com, or send a message through Twitter @ComcastCares. If your issue is urgent (service is down and you need it restored today), ask the automated system to schedule a callback rather than waiting on hold.
