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, account changes, technical support, and service issues. Wait times vary by time of day and season — calling early morning on a weekday typically means shorter holds than evenings or weekends.

Comcast also operates separate phone lines for specific needs. If you know which department you need before calling, you can reach them directly and skip the routing menu. The number above works for all services, but having the right line saves time.

When you call, have your account number ready — it appears on your bill and speeds up the process. If you do not have it, the representative can look up your account using your phone number or service address instead.

Phone numbers for specific Comcast Xfinity services

Comcast routes calls differently depending on what you need. If you have an internet outage, calling the internet support line may connect you faster than the general number. The same applies to TV service problems or phone line issues.

Internet technical support: 1-800-391-3000. This line handles connection problems, slow speeds, modem issues, and Wi-Fi questions. Representatives on this line have tools to run remote diagnostics on your modem and can often resolve problems without a technician visit.

TV service support: 1-800-266-2278. Use this for channel problems, DVR issues, on-demand errors, or billing questions specific to your TV package.

Phone service support: 1-800-391-3000. This number handles Comcast phone line outages, call quality problems, and phone-specific billing questions. It is the same line as internet support because many issues overlap.

What to expect when you call

After you dial, an automated system asks you to describe your issue or press numbers to route your call. Speaking naturally into the phone — saying "internet is down" or "I want to change my plan" — usually routes you faster than pressing menu numbers.

The system may offer to troubleshoot automatically before connecting you to a representative. For internet problems, this can mean running a modem restart or checking your connection status without waiting on hold. If the automated troubleshooting does not solve the problem, you stay on the line to speak with someone.

Wait times during peak hours (evenings and weekends) can reach 30 to 45 minutes. Calling between 8 a.m. and noon on a Tuesday, Wednesday, or Thursday typically means waits under 15 minutes. If you reach a very long queue, you can ask the system to call you back instead of holding.

Alternatives to calling

Comcast offers other ways to reach support without waiting on the phone. The Xfinity My Account app and website let you report outages, restart your modem remotely, check your bill, and change your service plan without calling.

Live chat is available through the Xfinity website and app during business hours. Chat representatives handle many of the same issues as phone support — billing questions, service changes, and basic troubleshooting — and typically have shorter wait times than phone lines.

For outages affecting your whole neighborhood, Comcast's website shows outage maps that tell you whether service is down in your area and when it is expected to return. Checking this first can save you a call if an outage is already known and being repaired.

Billing and account questions

The main customer service number (1-800-934-6489) handles all billing questions. Have your bill in front of you when you call so you can reference specific charges or ask about promotions that may lower your rate.

Comcast frequently offers discounts for new or returning customers, but these are not always shown on your bill automatically. If you have been a customer for over a year and your rate has increased, asking about current promotions may reveal discounts you are not receiving.

If you want to change your plan — add or remove channels, upgrade internet speed, or bundle services — the same number handles these requests. Representatives can tell you what packages are available at your address and what your new bill would be before you commit to a change.

Technical support and outages

For internet problems, the technical support line (1-800-391-3000) is faster than the general number. Before calling, restart your modem by unplugging it for 30 seconds and plugging it back in. Many connection problems resolve during this restart, and representatives will ask if you have tried this first.

If your modem does not have power or lights, check that the power cable is plugged in at both ends and that the outlet has power. A working modem shows a solid or blinking light — if all lights are off, the modem itself may need replacement.

For outages affecting your whole street or neighborhood, Comcast is usually already aware and working on repairs. Checking the outage map on the Xfinity website or app tells you the expected restoration time without calling. If the map shows no outage but your service is down, that is when a call to technical support is necessary.

Frequently Asked Questions

How long does it usually take to speak with someone?

Wait times range from 5 to 45 minutes depending on the time of day and how busy the call center is. Weekday mornings typically have the shortest waits. If you reach a very long queue, you can ask the automated system to call you back at your number instead of holding.

Can I schedule a technician visit by phone?

Yes. If you need an in-home technician for modem replacement, line installation, or problems that remote troubleshooting cannot fix, the representative can schedule a visit and give you a time window. Technician appointments typically come within 24 to 48 hours for urgent issues.

What if I want to cancel my service?

Call the main customer service number (1-800-934-6489) and ask to speak with the retention department. Before canceling, ask what promotions or discounts might lower your bill. Retention representatives often have offers not available to existing customers at regular rates.

Is there a number for Spanish-language support?

The same phone numbers work for Spanish-language support. When the automated system answers, you can select Spanish as your language preference, and you will be routed to a Spanish-speaking representative.

What if I am having trouble with my bill or think I was overcharged?

Call 1-800-934-6489 and have your bill ready. Explain the specific charge you question. Representatives can review your account history, confirm what you were charged for, and issue credits if an error occurred. Keep records of the call date and representative name for your records.
