Comcast's main customer service number and what it handles

Comcast's general customer service phone number is 1-800-934-6489. This line handles billing questions, service outages, account changes, and technical support for internet, TV, and phone service. Wait times vary by time of day and season — evenings and weekends are typically busier than weekday mornings.

When you call, have your account number ready. You can find it on your bill, in the Comcast app, or on your online account page. The system will ask you to verify your phone number or account number before routing you to the right department.

Comcast also operates department-specific numbers for certain issues. If you know which service you need help with, calling a direct line can sometimes reduce wait time, though the main number will eventually reach the same teams.

Department-specific phone numbers

Internet technical support: 1-800-391-3000. This line is for connection problems, slow speeds, modem issues, and router setup. Comcast will often send a technician to your home if the problem cannot be fixed over the phone, though this may involve a service fee depending on your plan and the cause of the issue.

Billing and account questions: 1-800-266-2278. Use this number to dispute a charge, ask about payment plans, request a credit, or change your billing address. Have recent bills available when you call.

Service disconnection or cancellation: 1-800-266-2278. Comcast routes cancellation requests through the same billing line. Be prepared for retention offers — the representative may propose discounts or service changes before processing your request.

Mobile service (Xfinity Mobile): 1-888-936-4968. This separate line handles questions about Comcast's wireless service, which runs on Verizon's network.

When phone lines are busy or you prefer not to call

Comcast offers several alternatives to phone support. The Xfinity app (available for iOS and Android) lets you check your bill, restart your modem, view outage maps, and message support without waiting on hold. The app also shows estimated wait times before you call.

The Comcast website at xfinity.com has a live chat option during business hours. Chat support is often faster than phone lines during peak times, though response times vary. You can also manage your account online — pay bills, change services, or view your usage without contacting anyone.

Comcast monitors social media (Twitter and Facebook) for customer service requests. Posting a direct message to @ComcastCares or @Xfinity often gets a response within a few hours, and the team can sometimes resolve issues faster than phone support.

What to expect during a call

After you verify your account, the system may route you to an automated troubleshooting menu before connecting you to a person. For internet issues, you may be asked to restart your modem or check your connection status. For billing or account changes, you will typically reach a representative directly.

If you are calling about a service outage, Comcast's system will tell you the estimated restoration time before you speak to anyone. You can also check outages on the Xfinity app or website without calling.

Representatives can usually resolve most issues in one call — billing credits, service changes, or scheduling a technician visit. If your issue requires escalation, you may be transferred to a specialist or given a case number and told you will receive a callback within a set timeframe.

Common reasons to call and what information to have ready

For technical problems, have your modem and router model numbers ready (usually printed on the devices themselves). The representative will ask what you are experiencing — no internet, slow speeds, or service on only one device — and may ask you to check lights on your modem or run a speed test.

For billing disputes, have your account number and the specific charge you are questioning. Bring the date and amount. If you believe you were overcharged, the representative can review your account history and issue a credit if warranted.

For service changes (adding a line, upgrading internet speed, or removing a service), have your current plan details available. Representatives can quote new prices and explain any equipment changes or installation fees before you commit.

Frequently Asked Questions

How long does it usually take to reach a person?

Wait times range from 5 to 45 minutes depending on time of day and call volume. Weekday mornings (9 a.m. to noon) are typically shortest. Evenings, weekends, and the first few days after an outage can have much longer waits. The Xfinity app shows estimated wait times before you call.

Can I schedule a callback instead of waiting on hold?

Yes. When you call, the system will offer a callback option if wait times are long. You provide a phone number and Comcast calls you back when a representative is available. This is useful if you do not want to hold for 30+ minutes.

What if I have a problem with my bill after the call?

You can call back using the billing number (1-800-266-2278) or use the Xfinity app to message support. Keep your case number from the first call if you received one. Comcast can look up your account history and see what was discussed.

Do I have to give my Social Security number over the phone?

Comcast may ask for the last four digits of your Social Security number to verify your identity, but they should not ask for the full number. If a representative asks for more than the last four digits, you can decline and ask them to verify you another way, such as by account number and phone number.

What if I need help in a language other than English?

Comcast offers Spanish-language support. When you call, the automated system will offer a language option at the beginning. You can also request an interpreter during a call, though wait times may be longer.
