  1. I have a new Citibank Credit Card by Costco. I have tried to log in to activate. Unless you have a mobile phone you want to put the app on or a citi bank account #, I see no way to activate.

  2. I am trying to activate my CitiBankPriority MasterCard. I have been unable to do so over my computer despite several tries. The activation service I spoke with did not recognize any of the information requested of me. I guess I need assistance or I need to give up trying. Robert P. Doolittle

  3. I cannot activate my Citi bank card. I go to, and it won’t take my information. What am I doing wrong???? Thanks
