Need help with your Xfinity account?

InternetSpeedX is independent, so we can't see or change anything on your Xfinity account, bill or equipment. For account, billing or service help, contact Xfinity directly using the number on your bill, the Xfinity app, or xfinity.com. Xfinity's customer service number is 1-800-XFINITY (1-800-934-6489).

Before you call, our guide to contacting Xfinity about slow speeds explains what to have ready.
