This article details the acceptable forms of proof of residency that may be required for Xfinity service.
In certain circumstances, you may have to provide proof of residency to obtain Xfinity service:

Two disconnects were processed on an account other than yours at your address within the past six to 12 months.
You have an outstanding balance from an account located at a different address.
Your new address still has service from the previous customer and no disconnect was processed on their behalf.
An account was created for your name/address but you did not sign up for service (to safeguard against identity theft).
In certain areas, your address's previous account was completely disconnected within the past six months, having never received any payment.

You must provide at least one primary and one secondary approved proof of residency document from the lists below. Documents must be complete, accurate and without alterations. Proof of residency must be presented at a Comcast Service Center.
