I tried setting up the new Citi Costco card the other day and I can't see a way to add it to my existing Citi account, it looks like it wants to make a new one. There's no way I'm dealing with the crap, I'll close out the credit account first. Anyone figure out how to add it to an existing Citi account?
I did in a round about way.
1) Before visiting
http://www.citi.com/CostcoSetup to activate my new card, I thought I would be smart and proactively login to my existing citicards.com account, amirite? Wrong, it didn't like it and asked me to logout.
2) So I went to the /CostcoSetup link, had to enter my new card number, expiration date, code, also my DOB and last 4 of SSN for verification.
3) Since I had previously logged in, my username was already prefilled but there was an option to create another Citi login (WTF would I do that)? Anyway it worked and I was able to login. My balance, limit and rewards seems to be right.
4) I was also prompted to update phone numbers and provided my cell just in case my card is compromised
again. My cell phone is usually with me and it's nice to be alerted via text/push notification of any suspicious account activity. Actually it would be nice if my credit cards were never compromised again, LOL that will never happen.
You
should be able to link your new card with your existing Citi card.
