Already Linked Phone Number and Email Address Setting up Second/Multiple Comast.net Login Account(s)

Frequent Visitor

Already Linked Phone Number and Email Address Setting up Second/Multiple Comast.net Login Account(s)

It's my understanding that Comcast does not allow to link multple Comcast service accounts for multiple addresses to one Comcast.net login.  

 

An additional Comcast.net login account must be established for each Comcast service account that I own.

 

That's a cumbersome approach, but ok, fine.

 

However, when I go to set up a new comcast.net login account, I receive error messages that state "Phone number is already linked to an existing comcast.net login account."  and "Email address is already linked to an existing comcast.net login account."

 

What's your solution/work around for this problem with your system???!

 

And don't tell me to use a different phone number, because I only have one phone number.  

 

And don't tell me to use a different email address because I own 24 rental properties most of which do or will have comcast service accounts that I am/will be responsible for.  It is virtually impossible (definitely unreasonable) to create and monitor each email account for each comcast service account on the 6 devices I use, let alone the accounts of my various property managers and what ever devices they use.

I have the same exact problem. I have called Comcast twice about this and each time they tell me it is resolved but it isnt. When I trie to enter my phonenumber into my account I get error message: "SH400.70.3: This Mobile Phone Number already exists."

Hi Mac_Zell,

 

It sounds like the phone number may be associated with a different username. I can investigate this. Please verify the phone number you are trying to use through private message. To send a private message click on my name "ComcastChe", then click private message me.

Hi JosephOfNazaret,

 

I can look into your issue as well. I will need to verify the phone number you're using. Please send me a private message by clicking on my name, "ComcastChe" then click private message me. In the body of this message please confirm the phone number.

Re: Already Linked Phone Number and Email Address Setting up Second/Multiple Comast.net Login Acc...

I am having the same issue. My cell phone number is on an old account. I don't know how to remove it from the old account. The system will not allow me to link my cell phone to my newly activated account due to:

This phone number is already associated with an XFINITY account

We cannot verify this mobile number, as it is already associated with another XFINITY account.

SH400.70.3: This Mobile Phone Number already exists.

 

Please help! Thanks.

Re: Already Linked Phone Number and Email Address Setting up Second/Multiple Comast.net Login Acc...

I am having a similar problem.  In my case, I had a Secondary user on my account which I deleted.  Now, when I try to add the phone number that was associated with that Secondary user to my account's Primary user information, I get the exact same message as babygirl357159.

 

Obviously, I cannot remove the number from the Secondary user because it is gone from my account completely (since I deleted it).  Thanks in advance for any help with this.

Re: Already Linked Phone Number and Email Address Setting up Second/Multiple Comast.net Login Acc...

Hi, Berman - I should be able to remove it from the secondary username (the one you already deleted). Please send me a private message with your full name, address, a phone number associated with your account. Also, I need the phone number that you try to add (if it's different from the one we have on the account). Thank you!

This just happened to me as well. I contacted tech support chat to set up a new appointment for a technician visit to lay coax cable, and was given a new account number with instructions to create a new account. Now being told email already exists. Did I just get set up with two separate services and accounts? Please advise.

I am also seeing this issue for my phone number and email.

 

This phone number is already associated with an XFINITY account

We cannot verify this mobile number, as it is already associated with another XFINITY account.

Back to Settings

SH400.70.3: This Mobile Phone Number already exists.

 

The account that it's supposed to be verified for won't let me manage the account, I get the error:

We couldn't sign you into My Account.

Unfortunately, you won't be able to manage your account at this time.

How is this fixed?

I'm not sure why, but for some reason I am not able to private message you. Whenever I go to the screen that would theoretically allow me to message you, nothing is popping up. Can you instead private message me first?

Hi ComcastElla,

 

I'm having the same issue as some of your other users and tried to send you a private message with my account information, as you suggested in your response shownbelow. Unfortunately, I get to a screen labeled "private message" but it does not allow me to enter anything. Can you send a message with a different link so we can resolve my issue?

I have the same problem. I have had two email accounts with Comcast for over 10 years. Now I can't use my one mobile phone number for both email accounts. Very frustrating.
