I got call from 1-888-934-6489 is this legit xfinity number

Concern moved here to the Customer Service help section for greater exposure to Comcast corporate employees (The Digital Care Team) for assistance.

That would be  1-800-XFINITY,  but generally Xfinity won't reach out to you for anything in regards to your active account.

 There are marketing calls that go out to non active customers.

But you still want to be careful on what information you provide due to hackers knowing how to mask phone numbers.
