The main Xfinity customer service number is 1-800-934-6489
Call that number to reach Xfinity technical support for internet, TV, or phone service problems. The line is open 24 hours a day. When you call, have your account number or the phone number associated with your account ready — the system will ask for one or the other to pull up your service details.
The automated system will route you based on what you say. If you tell it you have an internet problem, you'll reach the internet support team. If you say TV or phone, you'll reach those departments instead. You can also press numbers on your keypad to navigate the menu, though speaking your issue usually works faster.
Wait times vary by time of day. Early morning (before 9 a.m.) and late evening (after 8 p.m.) typically have shorter queues than midday. If you're calling about an outage affecting your whole neighborhood, the system may tell you that when ready and give you an estimated repair time without connecting you to an agent.

What information to have before you call
Gather these details before dialing so you don't waste time on hold looking for them. You need either your account number (found on your bill) or the phone number tied to your Xfinity account. If you're calling about a specific service — internet speed problems, a TV channel not working, or a phone line issue — have details about when the problem started and what you've already tried.
If you're calling about a bill or payment question, have your recent statement handy. If the issue is hardware-related (a modem, router, or TV box), know the model number if possible, though the agent can often look it up once they access your account. Write down any error messages or codes you're seeing on your screen — these help the technician narrow down the problem faster.
When to call versus other contact options
Phone support is fastest when you need when ready troubleshooting or when the problem is complex. A technician can walk you through steps in real time and adjust settings on your account remotely. Call if your internet is completely down, if you can't access your account online, or if you've already tried basic fixes and need hands-on help.
For billing questions, account changes, or non-urgent issues, Xfinity's website or mobile app often work just as well and don't require waiting on hold. You can pay a bill, change your service plan, or check your account balance without calling. If you prefer not to call but need to reach someone, Xfinity also offers chat support through their website and social media support through Twitter (@xfinityhelps).
If your internet is down and you can't call from home, use your mobile phone. If you don't have cell service, try calling from a neighbor's phone or a nearby business. Some people find it useful to call while the problem is actively happening so the technician can see real-time data from your modem.
What to expect during the call
After you give your account information, the automated system will ask what you're calling about. Answer as specifically as you can — "my internet is slow" or "my TV box won't turn on" works better than just "I have a problem." The system may run a quick diagnostic on your service before connecting you to an agent, which can save time.
Once you reach a technician, they'll usually ask you to describe the problem again. They may ask you to check lights on your modem or router, restart equipment, or check your connection type (WiFi or wired). These steps sound basic, but they solve the majority of issues. If the problem persists after these steps, the technician can escalate to a field technician who will visit your home, usually within 24 to 48 hours.
The call typically lasts 10 to 30 minutes for straightforward issues. More complex problems or those requiring a technician visit may take longer because the agent needs to schedule and document everything. At the end of the call, ask for a reference number — you'll need it if you have to call back about the same issue.
Troubleshooting steps before calling
Restart your modem and router before calling if your internet is slow or not working. Unplug the modem, wait 30 seconds, and plug it back in. Do the same for your router if it's separate. Wait two to three minutes for everything to come back online, then test your connection. This fixes roughly half of internet problems and will save you a phone call.
If you're having TV issues, restart the TV box the same way — unplug it, wait 30 seconds, plug it back in. Check that all cables are plugged in firmly at both the box and the wall outlet. If a specific channel isn't working, try another channel to see if the problem is widespread or isolated to one channel.
For phone service, check that the phone cable is connected to the correct port on your modem or gateway. If you're using a cordless phone, replace the batteries. If none of these steps work, write down exactly what's happening — no dial tone, calls drop after a few minutes, can't make outgoing calls — so you can tell the technician precisely what's broken.
If you can't reach someone or have a long wait
If the phone line is busy or wait times are extremely long, try calling back in 30 minutes. Peak times are typically between 10 a.m. and 6 p.m. on weekdays. If you're calling about an outage, the automated system will tell you the estimated repair time — you don't always need to speak to an agent.
While you wait on hold, you can also start a chat session through the Xfinity website or app. Some issues can be resolved through chat, and you won't lose your place in the phone queue. If you're a long-time customer with a good payment history, you may be able to reach a priority support line, though this varies by account status.
If you need to schedule a technician visit and don't want to wait on the phone, you can often schedule one through your online account or the mobile app. This is faster than calling and gives you a specific time window instead of a vague "within 24 hours" estimate.
Frequently Asked Questions
Is there a different number for billing or account questions?
No — 1-800-934-6489 handles all Xfinity services including billing, account changes, and technical support. The automated system will route you to the right department based on what you say. For billing only, you can also log into your account online and pay or view your bill without calling.
What if I'm calling from outside the United States?
The 1-800 number only works from within the U.S. If you're calling from abroad, you'll need to use an international calling service or contact Xfinity through their website. Check your account page for international contact options, as they vary by country.
Can I schedule a technician visit over the phone?
Yes, the technician can schedule a visit during your call. They'll give you a date and time window, usually 24 to 48 hours out. You can also schedule online through your account or the Xfinity app, which is often faster and doesn't require waiting on hold.
What if I'm having trouble with my bill or was overcharged?
Call the same number and tell the automated system you have a billing question. A billing specialist will review your account and explain charges. If you were overcharged, they can issue a credit. Keep your bill handy so you can reference specific charges while on the call.
Do I need to stay on the line the whole time, or can I request a callback?
Many Xfinity support calls allow you to request a callback instead of waiting on hold. When the automated system connects you, listen for the option to receive a call back at your number. This lets you hang up and do other things while you wait, though availability depends on current call volume.
