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

That number connects you to Comcast's general customer service line, where you can report problems with your cable or phone service, ask about your bill, or discuss changes to your account. Wait times vary by time of day and season — calling early morning on a weekday is usually faster than calling in the evening or on weekends.

Comcast also operates a separate line for billing questions: 1-800-391-3000. If you know your issue is about a charge on your bill or a payment problem, that line may get you to the right department faster than the main number.

Before you call, have your account number ready — it appears on your bill and in the top right corner of your online account. You can also find it by logging into Comcast.com and viewing your account details. Having this number saves you time during the automated menu system.

  • Have your account number ready before calling — it appears on your bill and speeds up the automated system.

What to expect when you call

When you dial 1-800-934-6489, you will hear an automated menu. The system will ask you to describe your issue in your own words or press numbers to select from categories like "billing," "service problems," or "account changes." Speaking naturally often routes you faster than pressing numbers, though both methods work.

After the automated menu, you will wait for a representative. During peak hours (5 p.m. to 9 p.m. on weekdays, or Saturday afternoons), wait times can reach 20 to 45 minutes. Off-peak times like 9 a.m. to noon on a Tuesday or Wednesday typically mean 5 to 15 minutes of waiting.

The representative can troubleshoot service problems, explain charges on your bill, process changes to your plan, or schedule a technician visit. If your issue requires a technician — for example, if your cable box is not working or your internet speed is unusually slow — they will book an appointment and give you a window of time when the technician will arrive.

Other ways to reach Comcast without calling

If you prefer not to wait on hold, Comcast offers chat support through Comcast.com. Log into your account, look for the "Help" or "Support" section, and select "Chat with us." Chat wait times are often shorter than phone wait times, though you will type back and forth rather than speak.

The Xfinity mobile app (available on iPhone and Android) also has a chat feature and lets you view your bill, restart your modem or cable box remotely, and check your service status without calling. If your internet is down, you can still use the app on your phone's cellular data to report the problem.

For billing questions only, you can also mail a check or money order to the address on your bill, or set up automatic payments through your bank. This does not solve the problem faster, but it removes the need to call if you straightforward want to pay your bill.

What information Comcast needs from you

When you call or chat, a representative will ask for your account number, phone number associated with the account, or the service address. They may also ask for the last four digits of the Social Security number on the account for verification purposes.

If you are calling about a service problem, have the following ready: the type of equipment that is not working (modem, cable box, router), what you have already tried (restarting the device, checking cables), and whether the problem affects all devices or just one. This information helps the representative decide whether they can fix it over the phone or need to send a technician.

If you are calling about your bill, have your most recent bill in front of you. Look for any charges you do not recognize, and note the dates they appear. This makes it easier for the representative to explain what each charge is for.

When to call versus when to wait

Call when ready if your cable, internet, or phone service is completely out. Comcast prioritizes outage calls, and the representative can tell you whether the problem is on their end (affecting your whole neighborhood) or your equipment. If it is an outage, they may credit your account automatically.

You can wait a day or two if your issue is a billing question, a request to change your plan, or a minor service problem like a single channel not working. These issues do not get worse by waiting, and calling during off-peak hours will be faster and less frustrating.

If you have a service problem that is not an outage — for example, your internet is slow or your cable picture is pixelated — try restarting your modem and cable box first. Unplug each device, wait 30 seconds, and plug it back in. Many problems fix themselves this way, and you will avoid a phone call altogether.

Comcast phone service troubleshooting before you call

If your Comcast phone line is not working, check whether your cable modem has power and is connected to the wall outlet. The modem powers your phone service, so if the modem is off or unplugged, your phone will not work even if your internet is fine. Restart the modem by unplugging it for 30 seconds.

Also check that the phone cable is plugged into the correct port on the modem — it should be labeled "Phone" or "Tel." If the cable is loose or in the wrong port, your phone will not work. Reconnect it firmly and wait two minutes for the modem to recognize the phone line.

If you have a backup phone line through another provider (like a cell phone), use that to call Comcast if your Comcast phone is still not working. This way you can report the problem while you are on the phone with them, and they can troubleshoot in real time.

Frequently Asked Questions

Is there a way to skip the automated menu and talk to a person right away?

Not officially, but saying "representative" or "agent" when the automated system asks you to describe your issue sometimes routes you to a person faster. You can also try pressing 0 repeatedly, though this does not always work with Comcast's system. Your best option is to call during off-peak hours so the wait is shorter even if you go through the full menu.

What if I get disconnected while on hold with Comcast?

Call back when ready. You will go to the back of the queue, but you will not lose your place permanently. If you are disconnected multiple times, try calling the billing line (1-800-391-3000) instead, or use the chat feature on Comcast.com to avoid being on hold.

Can I schedule a technician visit without calling?

Yes. Log into your account on Comcast.com, go to the Support section, and look for "Schedule a service visit" or "Book an appointment." You can select your preferred date and time window. If no appointments are available online, you will need to call to book one.

What if I am calling about a bill I think is wrong?

Call the billing line at 1-800-391-3000 with your bill in front of you. Point out the specific charge you question and the date it appears. The representative can explain what it is for, explore a credit if it is an error, or adjust your plan if you were charged for a service you did not request.

Does Comcast offer phone support in languages other than English?

Yes. When you call, the automated system will ask if you need Spanish or another language. Select your preference, and you will be routed to a representative who speaks that language. Wait times may be longer for non-English lines depending on your area.
