The main Comcast customer service number and what it handles
Comcast's general customer service line is 1-800-934-6489. This number handles billing questions, service issues, account changes, and technical support for internet, TV, and phone service. Wait times vary by time of day and season — calling early morning on a weekday typically means shorter holds than evening or weekend calls.
When you call, have your account number ready. You can find it on your bill, in the Xfinity app, or on your online account page. The automated system will ask which service you need help with and may route you to a specialist faster if you answer clearly.
Comcast also operates separate lines for specific needs. If you are calling about a new service order or to upgrade, you may reach a sales line instead of support, which can add time to your call. Asking the automated system for "existing customer support" or "billing" helps you reach the right team sooner.

When to call versus using the Xfinity app or website
Not every issue requires a phone call. The Xfinity app and Comcast's online portal let you pay bills, view usage, restart your modem, check service status in your area, and update account information without waiting on hold. If your internet is down, the app can tell you whether an outage is affecting your neighborhood and when service is expected to return.
Call the phone line when you need to dispute a charge, change your service plan, add or remove a service, report a persistent technical problem that restarting did not fix, or discuss your bill. These conversations often require back-and-forth discussion and access to your account history, which a representative can provide faster than navigating menus online.
If you are having trouble logging into your online account, calling is usually faster than trying to reset your password through the website. A representative can verify your identity and reset access in minutes.
Technical support and internet outage reporting
If your internet is down, you can report it by phone at 1-800-934-6489, but the Xfinity app often gives you faster information about whether an outage is happening in your area. The app shows estimated restoration time and lets you check the status without speaking to anyone.
For technical troubleshooting, a representative will usually ask you to restart your modem and router, check cable connections, and run a speed test. Have your modem and router nearby when you call. If you have already restarted and the problem persists, the representative may schedule a technician visit or replace your equipment.
Comcast charges for technician visits if the problem is determined to be on your end rather than their network. Ask the representative whether a visit fee applies before scheduling.
Billing and account changes
Call 1-800-934-6489 to discuss your bill, set up autopay, change your payment method, or ask about discounts. Representatives can sometimes lower your rate if you have been a customer for a while or if a promotional rate has expired. They cannot always offer the same discount a new customer would receive, but it is worth asking.
If you see a charge you do not recognize, a representative can explain it or dispute it. Billing disputes can take 30 to 60 days to resolve, so ask for a reference number and follow-up timeline when you call.
To add or remove services — such as adding HBO Max or dropping cable TV — call the same number. You can also make these changes in the Xfinity app, but calling lets you negotiate pricing before confirming.
Wait times and best times to call
Comcast does not publish official wait time data, but customers generally report shorter waits on weekday mornings between 8 a.m. and 11 a.m. in their local time zone. Evenings, weekends, and the first few days after a major outage see longer holds.
If you reach a long wait, you have options. The Xfinity app can handle many routine requests. You can also ask the automated system to call you back instead of holding — this keeps your line free and Comcast calls you when a representative is available, though callback wait times are not always shorter.
Some issues, like service outages affecting many customers at once, can cause system-wide delays. Checking the Comcast status page or Xfinity app before calling tells you whether a widespread outage is the reason for delays.
What to have ready before you call
Gather these items before dialing to make your call shorter: your account number (on your bill or in the Xfinity app), the phone number or email associated with your account, your modem and router model numbers (on the devices themselves or in the Xfinity app), and any recent bills if you are calling about charges.
If you are calling about a technical problem, note what you have already tried — restarting your modem, checking cables, running a speed test — so the representative does not ask you to repeat steps. Write down the time the problem started and whether it happens all the time or only during certain hours.
If you are calling about a service outage, have your address ready. Comcast needs to know your exact location to tell you whether the outage affects your area.
Alternative contact methods
Comcast offers support through the Xfinity app, which has a chat feature for non-urgent questions. Response times vary, but chat can be faster than phone during peak hours. You can also message Comcast through social media platforms like Twitter or Facebook, though these are typically slower than phone or app chat.
For billing or account questions, logging into your online account at xfinity.com shows your bill history, current charges, and service details. You can pay your bill, view usage, and update your payment method without calling.
If you need to set up a new service or move your service to a different address, you can start the process online, but you will likely need to call to finalize the order and schedule installation.
Frequently Asked Questions
What is the Comcast customer service number for billing only?
The same number — 1-800-934-6489 — handles billing, technical support, and account changes. When the automated system answers, you can say "billing" to be routed to the billing department faster. You do not need a separate number.
Can I schedule a technician visit by phone?
Yes. Call 1-800-934-6489 and tell the representative you need a technician. They will ask about your issue, check availability in your area, and schedule a visit. You can also schedule through the Xfinity app under "Troubleshooting" or "Service Appointments."
What should I do if I have been on hold for a very long time?
Ask the automated system for a callback instead of holding. You can also hang up and try calling back at a different time — early morning on a weekday usually has shorter waits. If your issue is not urgent, the Xfinity app or online account portal may solve it without calling.
Is there a number for Comcast billing disputes?
Billing disputes go through the main customer service line at 1-800-934-6489. A representative will review the charge with you and can dispute it if you believe it is incorrect. Ask for a reference number and timeline for resolution before ending the call.
Can I reach Comcast customer service outside the United States?
The 1-800 number works only from within the United States. If you are outside the U.S., log into your account at xfinity.com or use the Xfinity app to manage your account. You may also contact Comcast through the website's contact form for international inquiries.
