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

Call that number to reach Xfinity's general customer service line. The system will route you based on what you need — billing questions, service changes, or technical problems. If you have an active Xfinity account, have your account number or the phone number associated with your account ready before you call. This speeds up the process because the system can pull up your service details.

Wait times vary by time of day and day of week. Calling on a weekday morning between 9 a.m. and noon tends to be faster than calling in the evening or on weekends, when more people are home and calling in. If you reach a long queue, you can ask to receive a callback instead of holding.

What to expect when you call for technical support

When you call 1-800-934-6489 and select the technical support option, an automated system will ask you to describe your problem. You can say things like "internet not working" or "cable channels not loading." The system listens to your words and may try basic troubleshooting steps with you before connecting you to a person.

If the automated system cannot fix the problem, you will be transferred to a technical support representative. They will ask you to describe what is happening, what you have already tried, and what equipment you have (modem, router, TV box). Be specific about what is not working — for example, "the internet drops every 10 minutes" is more useful than "internet is slow."

The representative may ask you to restart your modem or router, check cable connections, or run a speed test. Have your equipment nearby so you can do these things while on the call. Most internet and cable problems are solved during the call itself.

When to call versus using other contact methods

Phone is the fastest way to reach someone if your internet is completely down and you cannot use the website or app. If your internet is working but slow, or if you have a billing question that is not urgent, you may get a faster answer through Xfinity's website chat or the Xfinity mobile app.

The Xfinity website (xfinity.com) has a chat option in the bottom right corner during business hours. The mobile app also offers chat support. These options often have shorter waits than the phone line because fewer people use them. However, if you need someone to walk you through physical steps — like restarting equipment or checking connections — the phone is usually clearer because you can describe what you see in real time.

Troubleshooting before you call

If your internet or cable is not working, try these steps before calling. First, unplug your modem (the device that connects to your wall outlet and your router) and wait 30 seconds. Plug it back in and wait two to three minutes for all the lights to come back on. Then unplug your router (if you have a separate one) and wait 30 seconds, then plug it back in.

While the equipment restarts, check that all cables are plugged in firmly — the cable from the wall to your modem, the cable from your modem to your router, and any cables from your router to your devices. Loose cables are the most common reason for service problems. If you have a TV box, restart it the same way: unplug it, wait 30 seconds, and plug it back in.

If restarting fixes the problem, you do not need to call. If the problem comes back within a few hours, or if restarting does not help at all, then call 1-800-934-6489. When you call, tell the representative that you have already restarted your equipment — this tells them the problem is not something straightforward and they can move to the next step faster.

What information to have ready

Before you call, gather these things: your account number (on your Xfinity bill), the phone number associated with your account, and the model number of your modem and router if you know it. The model number is usually on a sticker on the back or bottom of the device. If you do not know it, you can say so — the representative can look it up using your account.

Also write down what is not working and when it started. For example: "internet drops every evening around 6 p.m. starting three days ago" or "cannot get channel 45, other channels work fine." This information helps the representative understand the problem faster and decide whether they can fix it over the phone or need to send a technician to your home.

If you need a technician visit

Some problems require a technician to come to your home — for example, if the cable line outside your house is damaged, or if your modem needs to be replaced. The representative on the phone will tell you if this is necessary. If a visit is needed, they will offer you appointment times. Technician visits are usually scheduled within one to three business days, depending on how busy the local team is.

When the technician is scheduled, you will receive a confirmation with the date, time window, and technician name. Xfinity typically gives a four-hour window (for example, "between 1 p.m. and 5 p.m."). Someone 18 or older needs to be home during that window. If you need to reschedule, you can call 1-800-934-6489 again or reschedule through the Xfinity app.

Frequently Asked Questions

Is there a separate number for billing versus technical support?

No, 1-800-934-6489 handles both. The automated system will ask what you need and route you accordingly. If you reach the wrong department, the representative can transfer you to the right one, so you do not need to hang up and call again.

What hours is Xfinity customer service available?

Xfinity customer service is available 24 hours a day, 7 days a week. However, wait times are longer late at night and on weekends. If you call at 2 a.m. on a Sunday, you may wait longer than if you call at 10 a.m. on a Tuesday.

Can I schedule a callback instead of waiting on hold?

Yes. When you reach the queue, the system will offer you the option to receive a callback. You can give a phone number and a time window, and a representative will call you back when it is your turn instead of you holding the line.

What if I have a problem with my bill, not my service?

Call the same number, 1-800-934-6489, and tell the system you have a billing question. You will be routed to the billing department. Have your account number and bill handy so you can reference specific charges.

Do I need to restart my equipment before calling, or will the representative do it with me?

You do not have to restart before calling, but it helps. If you restart and the problem goes away, you save time by not calling at all. If restarting does not help, tell the representative you already tried it so they know to move to more advanced troubleshooting steps.
