Comcast is open on Sunday, but hours vary by service type

Comcast customer service operates on Sunday, though the hours depend on whether you need phone support, want to visit a store, or are looking to handle something online. Phone support is typically available from 8 a.m. to 8 p.m. on Sunday in most areas, but this can shift by region. Comcast stores themselves have reduced Sunday hours — many open at 10 a.m. or 11 a.m. and close by 5 p.m. or 6 p.m., though some locations stay closed on Sunday entirely. Your online account is always accessible through the Comcast website or the Xfinity app, regardless of the day or time.

The fastest way to confirm Sunday hours for your specific location is to visit Xfinity.com, sign into your account, and look for the "Contact Us" section, which shows local store hours and phone availability. You can also call 1-800-934-6489 to speak with someone directly about your service, though wait times tend to be longer on weekends.

Phone support availability on Sunday

Comcast's main customer service line at 1-800-934-6489 is open on Sunday from 8 a.m. to 8 p.m. in most time zones, but this is not may provide across all regions. Some areas may have slightly different hours, and technical support lines sometimes operate on a different schedule than billing support. If you call outside these hours, you will reach an automated system that can handle basic requests like paying your bill or scheduling a technician visit.

Sunday wait times are typically longer than weekday calls because more people contact Comcast on weekends. If you have a non-urgent question, calling Monday through Friday usually means shorter hold times. For service outages or technical emergencies, Comcast maintains 24/7 support, so you can always reach someone if your internet or TV is down.

Comcast store hours on Sunday

Comcast retail locations operate on Sunday in many areas, but hours are shorter than weekdays. Most stores open between 10 a.m. and 11 a.m. and close between 5 p.m. and 6 p.m., though some locations do not open on Sunday at all. Hours vary significantly by store, so you cannot assume your nearest location follows the standard pattern.

To find your local store's exact Sunday hours, visit Xfinity.com, enter your zip code in the store locator, and select your nearest location. The page will show the full weekly schedule. You can also call ahead to confirm before making a trip, especially if you need a specific service like equipment pickup or return.

What you can do online anytime

The Xfinity website and mobile app are available 24 hours a day, seven days a week, including Sunday. You can pay your bill, view your account balance, check your data usage, restart your modem, schedule a technician visit, and manage your services without waiting for a representative. Many common issues can be resolved through the self-service options in your account.

If you prefer not to call or visit a store on Sunday, handling your request online often takes less time and does not depend on business hours. The app is available on iOS and Android, and the website works on any browser.

Technical support on Sunday

Comcast's technical support line operates on Sunday, though the hours may differ slightly from general customer service. For internet, TV, or phone issues, you can call 1-800-934-6489 and select the technical support option. If you have an active service outage in your area, Comcast's system will usually tell you this automatically and provide an estimated repair time.

Before calling, try restarting your modem and router — this fixes many common connection problems and takes about five minutes. If that does not work, the technician can walk you through additional troubleshooting steps or schedule a visit to your home if needed.

Billing and account questions on Sunday

Comcast's billing department is open on Sunday during the standard phone support hours of 8 a.m. to 8 p.m. in most areas. You can ask about your bill, make a payment, discuss your plan options, or request a credit for service issues. Billing questions can also be handled entirely through your online account without calling.

If you need to dispute a charge or discuss a large bill, Sunday may not be the best time to call because wait times are longer. However, if you simply need to make a payment or check your balance, the online account or automated phone system can handle this immediately.
