Xfinity does not run a phone line that is officially open 24 hours a day. The number listed on xfinity.com, 1-800-XFINITY (1-800-934-6489), carries no published hours anywhere on Comcast’s own site. The two channels Xfinity does state are open 24/7 are chat through Xfinity Assistant and the Xfinity app, not the phone line itself.
The three official ways to contact Xfinity
Comcast lists exactly three channels on its own contact page: the phone number above for residential accounts, a separate line for Xfinity Mobile, and Xfinity Assistant chat. A fourth option, the Xfinity app, wraps chat and self-service tools into one place.

What each channel is actually good for
The four options are not interchangeable. Here is what Xfinity’s own support pages say about each one.
| Channel | Contact | What it covers | Stated hours |
|---|---|---|---|
| Residential phone | 1-800-XFINITY (1-800-934-6489) | Billing, internet, TV, home phone, general account issues | Not published |
| Xfinity Mobile phone | 1-888-936-4968 | Mobile lines and devices only | Not published |
| Xfinity Assistant | Chat on xfinity.com/xfinityassistant | Billing questions, troubleshooting, general support | 24/7, stated on the contact page |
| Xfinity app | Download on iOS or Android | Account management, outage checks, troubleshooting | 24/7 real-time support, stated on Xfinity’s own article |
Skip the call for these fixes first
A lot of calls to Xfinity are for problems you can fix without waiting on hold. If your gear shows connected but nothing actually loads, work through 10 fixes for a WiFi connection that won’t get you online before you dial.
If you only need into your own equipment’s settings, not Xfinity’s system, logging into your router takes a couple of minutes and skips support entirely. The same goes for renaming your network: you can change your WiFi name from your iPhone in about five minutes without opening a support ticket.
Why third-party numbers keep showing up in search
Search for an Xfinity number and you will find pages listing numbers Comcast never published. Some are outdated support lines Comcast retired. Others belong to unaffiliated sites that route calls to third parties, not Comcast agents.
The two numbers on this page came directly from xfinity.com’s own contact and rights pages, not from a directory site. If a number you find elsewhere does not match 1-800-934-6489 for residential service or 1-888-936-4968 for mobile, treat it as unverified.
FAQ
Is there a 24 hour Xfinity customer service number?
Xfinity has not published set hours for its phone line. The channels it explicitly calls 24/7 are Xfinity Assistant chat and the Xfinity app, so those are the more reliable options outside business hours.
What is Xfinity’s real customer service number?
For residential internet, TV, and home phone accounts, it’s 1-800-XFINITY (1-800-934-6489). Xfinity Mobile has its own line, 1-888-936-4968.
How do I skip the automated system and reach a person?
Start with Xfinity Assistant chat or the app. Both can hand you off to a live agent, and Xfinity’s own guidance points new contacts there before the phone line.
