I only have one phone - my cell phone. This appears on My Account/Settings as my preferred phone number. I wanted to set up text alerts, so it wants me to add my mobile number. When I try to do so, it tells me that number already exists on my account.
Edit: I entered this under the Customer Service forum, but the system moved it here. This is on the Xfinity/ My Account webiste, not mobile.
Just wasted 30 minutes going through circular logic with somone on live chat.
Does anyone know how to get around this problem?
I only have one phone - my cell phone, so it is listed as my preferred phone number on the account.
If I try to add a text alert, it says I don't have a mobile number and asks me to enter one. I enter one and it sends a verification code to my phone.
I enter the verification phone and it tells me
This Mobile Phone Number already exists.
TL;DR - Your cell number may still be tied to an old account, Comcast may have to merge the old account username with your existing one.
I recently had this same issue when trying to set up 2-step verification to sign in to my account. After calling comcast a bunch of times, we figured out that my number was still attached to an old account that I had with them. I had moved from state to state a few times, cancelled my previous accounts and then set up new accounts. Turns out that somehow, my cell phone was still attached to one of my old accounts, even though the account had been deactivated.
Their initial solution was to dissociate the number from that old account, but for some reason they could not do so or it just did not work (they said to wait 48 hours before attempting the 2-step verification set up, which I did).
Finally one of the billing and accounting folks (or mght have been someone from security department) who knew what they were doing suggested merging the Username from the previous account with the current one. They basically added the old username to my new (current) account as an authorized user. And that ensured the phone number was only tied to one account - the current one.
I was then able to complete the initial set up I wanted without getting a message that the number already existed.
Hope this helps.
This is such a stupid implementation of 2-factor authentication. Why not offer using a OTP through a mobile app that cycles through 6 digit codes every 60 seconds??????????????? I use this option on a vast majority of my accounts. That would be SO MORE intelligent. I have ONE MOBILE PHONE NUMBER, like a majority of other ppl. I have 2 Comcast accounts, one for home service, and one for business. So dumb, comcast. or xfinity. sofa king dumb.

Agreed. I've had my phone number tied to a Comcast account since it was a subaccount from my parents, then could never add it as a "verified phone number" to my personal Xfinity account after setting it up in college, to a Comcast Business account, or to the resdential account I got after that. It would be nice if there was a way to fix this, but an even better solution at least for two-factor authentication would be offline TOTP support (e.g. Google Authenticator, Authy, 1Password). With the recent advent of number porting scams that wreck your identity after getting SMS 2FA codes, Comcast really should get with the program of 2FA without SMS.
