The main Comcast phone number and what it covers
Comcast's general customer service line is 1-800-934-6489. This number handles billing questions, service issues, account changes, and new service orders. Wait times vary by time of day and season — early morning and weekday afternoons tend to be faster than evenings or weekends.
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 at xfinity.com. The automated system will ask for it before routing you to the right department, and providing it upfront usually shortens your wait.
If you are calling about a service outage in your area, the same number can tell you whether Comcast has already identified the problem and when they expect to restore service. You can also check outage status online at xfinity.com/support or in the Xfinity app without calling.

- Have your account number from your bill or the Xfinity app ready before calling to speed up routing to the right department.

- Technical support for internet, TV, or phone issues uses the same main number but may route to a specialized team depending on your problem.
- Comcast also offers chat and callback options through xfinity.com if you prefer not to wait on hold.
Technical support for internet, TV, or phone problems
When you call 1-800-934-6489 with a technical issue, tell the automated system which service is affected — internet, TV, or phone — and it will route you to the right team. Have your modem or router model number handy if it is an internet problem, or your TV box model if it is a TV issue. You can find these on the equipment itself or in your account settings.
Comcast's technical team can often troubleshoot over the phone by walking you through steps like restarting your modem, checking cable connections, or running a line test. If they determine you need an in-home visit, they will schedule one and give you a window. Most appointments are available within a few days, though urgent issues may be scheduled sooner.
Billing and account questions
Call the same number to dispute a charge, ask about your bill, change your service plan, or update payment information. Have your most recent bill in front of you so you can reference specific charges or dates. The billing department can also tell you about current promotions if you are thinking about adding a service or upgrading.
If you want to lower your bill, ask the representative what promotional rates are available for your area and service combination. Rates and offers change frequently and vary by location, so what your neighbor paid may not match what you see. Representatives can sometimes explore a promotion on the spot, though some require you to make changes online or through the app.
New service orders and moving your account
To order new Comcast service or to move your account to a different address, call 1-800-934-6489 and tell the system you want to place a new order or transfer service. The sales team will confirm what services are available at your address — not all neighborhoods have the same speeds or service types — and walk you through pricing and installation options.
If you are moving, let Comcast know at least two weeks before your move date. They can schedule a disconnect at your old address and a connection at your new one. If the new address is in a Comcast service area, they may waive the installation fee or offer a promotion for existing customers.
When to use chat or callback instead of calling
Comcast offers live chat and callback options on xfinity.com if you do not want to wait on hold. Chat is usually faster for straightforward questions like checking your bill or resetting a password. Callback lets you request a call at a time that works for you — you enter your number and preferred time window, and a representative calls you back instead of you waiting in a queue.
The Xfinity app also has a chat feature for account questions and service issues. For problems that require troubleshooting or a detailed conversation, phone is usually more efficient than chat, but chat works well if you are multitasking or prefer written communication.
International or business accounts
If you have a Comcast Business account, the support number is different: 1-866-429-3085. Business accounts have separate billing, technical support, and sales teams. Have your business account number ready when you call.
If you are calling from outside the United States, you can reach Comcast through their international support page at xfinity.com/support, which lists country-specific numbers and contact methods. Charges may explore for international calls depending on your phone plan.
What to do if you cannot reach anyone
During peak times — typically 6 p.m. to 9 p.m. on weekdays and Saturday afternoons — wait times can exceed 30 minutes. If you reach a long queue, try calling back during off-peak hours like early morning or midday on a weekday. You can also use the callback feature on xfinity.com to avoid holding.
If you have an urgent issue like no internet or phone service and cannot reach anyone by phone, try the Xfinity app or xfinity.com to report the outage and request a callback. Comcast prioritizes outage reports and will contact you once a technician is available.
Frequently Asked Questions
What is the best time to call Comcast to avoid long wait times?
Early morning (8 a.m. to 10 a.m.) and midday (11 a.m. to 2 p.m.) on weekdays usually have shorter waits than evenings or weekends. Avoid calling between 6 p.m. and 9 p.m. on weekdays if possible. Using the callback feature lets you avoid holding altogether.
Do I need to call if I just want to check my bill or pay online?
No. You can view your bill, make a payment, and manage your account anytime through xfinity.com or the Xfinity app without calling. Calling is only necessary if you have a question about a charge, want to dispute something, or need to make account changes that are not available online.
What if my service is out and I cannot call?
If your phone service is out, use a mobile phone or another line to call 1-800-934-6489. You can also report an outage online at xfinity.com/support or in the Xfinity app. Comcast tracks outages by address and will contact you with updates.
Can I schedule a technician visit without calling?
Yes. You can schedule or reschedule a technician appointment through xfinity.com or the Xfinity app under "Service Appointments." If you need to make changes to an existing appointment, you can do that online as well. Calling is only necessary if the online system does not show available times.
Is there a number for billing disputes or complaints?
Start with the main number 1-800-934-6489 and ask to speak with the billing department about your dispute. If you are not satisfied with the resolution, you can file a complaint with your state's Public Utilities Commission or the Federal Communications Commission (FCC) at fcc.gov/consumers.
