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 changes, technical support, and account issues for both internet and phone customers. 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 system will ask which service you need help with — internet, TV, phone, or mobile — and route you to the right department. If you know your account number before the automated system asks, you can often skip ahead in the menu.
Comcast also operates separate lines for specific situations. The number for new service orders is 1-800-266-2278. If you are calling about a billing dispute or want to discuss your bill before paying, the billing department can be reached through the main line and then selected from the menu.

What to expect when you call
After you dial, an automated system will ask you to state your issue or press numbers on your keypad. You can say things like "billing," "technical support," or "account changes" and the system usually understands. If it does not, you can press 0 to reach a representative, though this may add time to your wait.
Once connected to a person, they will verify your identity by asking for your account number, phone number, or the last four digits of the Social Security number on file. This takes a few minutes but is required before they can discuss your account. After verification, they can look up your service, see recent charges, and make changes to your account.
Most calls are recorded for quality and training purposes. The representative will usually mention this at the start of the call. If you have a sensitive question or want to know about recording, you can ask before proceeding.
Phone support alternatives to calling the main line
If you do not want to wait on hold, the Xfinity app and Xfinity.com both offer live chat with a representative. Chat wait times are often shorter than phone wait times, and you can continue using your device while waiting. Chat is available during the same hours as phone support.
You can also manage many account tasks without calling at all. The Xfinity app and website let you view your bill, make a payment, restart your modem, check your data usage, and change your service plan. For technical issues, the app has a troubleshooting section that walks through common problems like slow internet or no dial tone.
If you prefer in-person help, Comcast has local service centers in most areas. You can find the nearest one by entering your zip code on Xfinity.com. Walk-in hours vary by location, and some centers require an appointment. Visiting in person can be useful if you need to pick up equipment or discuss complex billing issues face-to-face.
Reaching Comcast for specific issues
If your internet is not working, call the main number and select the technical support option. Have your modem and router nearby so the representative can walk you through basic steps like restarting them. Most internet issues resolve within 15 minutes of troubleshooting. If they do not, the representative can schedule a technician visit to your home.
For phone service problems — no dial tone, calls dropping, or not receiving calls — also use the main number and choose phone support. The representative can check whether your phone line is active, test the connection, and restart your equipment remotely. Phone issues are often fixed without a technician visit.
Billing disputes and payment arrangements also go through the main line. If you have been charged incorrectly or want to set up a payment plan, the billing department can review your account and make adjustments. Keep your bill handy so you can reference specific charges.
Best times to call and how to reduce wait time
Comcast phone lines are busiest on weekday evenings between 5 p.m. and 9 p.m., and on Saturday and Sunday afternoons. If you can call on a weekday morning between 8 a.m. and noon, you will typically wait less than 10 minutes. Tuesday through Thursday mornings are usually the slowest days for call volume.
Calling right after a major outage or service change — such as a widespread internet outage or a billing system update — will result in longer waits because many customers call at once. If you are not in a rush, waiting a day or two after a known issue can significantly reduce your hold time.
Having your account number, service address, and a description of your issue ready before you call will make the conversation shorter. If you are calling about a specific charge, have that bill in front of you. The faster you can provide information, the faster the representative can help.
What to do if you cannot reach Comcast by phone
If the phone line is consistently busy or you are unable to get through, try the Xfinity app or website chat first. Chat representatives can often resolve issues just as quickly as phone representatives and may have shorter wait times. You can also send a message through the Xfinity app's support section and receive a response within a few hours.
For billing or service issues that are not urgent, you can also contact Comcast through social media. Comcast has official accounts on Twitter and Facebook where customer service representatives monitor messages. Response times on social media are typically longer than phone or chat, but this option works if you prefer written communication.
If you have a complaint about your service or billing that you feel was not resolved by phone, you can file a complaint with your state's public utilities commission. Each state has its own commission that oversees cable and internet providers. Filing a complaint does not charge you anything and creates an official record that Comcast must respond to.
Frequently Asked Questions
Is there a way to skip the automated menu and talk to a person right away?
Pressing 0 during the automated menu will usually connect you to a representative, but you may wait longer than if you navigate the menu to the correct department first. If you tell the system your issue clearly, it will route you to the right department and you will reach a person faster.
What if I call after hours?
Comcast phone support is available 24 hours a day, 7 days a week. However, some departments like billing may have limited hours. The automated system will tell you if a department is closed and offer to take a message or schedule a callback.
Can I reach a specific representative or department?
You cannot request a specific person, but you can ask to be transferred to a supervisor or manager if you feel your issue was not resolved. Supervisors have more authority to make account adjustments and can often help with complex billing or service disputes.
Do I need to call from the phone number on my account?
No. You can call from any phone. The representative will verify your identity by asking for your account number or other information on file, so it does not matter which phone you use to reach them.
What if I have a question about my Comcast mobile service?
Comcast mobile support is handled through the same main number, 1-800-934-6489. Select the mobile option from the menu, and you will be routed to the mobile support team. They can help with billing, service issues, and device problems.
