Question

Are there a different credit ranges?

Answer 1

The Signature cards have a range of additional "concierge" services available to the card holder in addition to the usual platinum card perks. Also, it does not have a preset spending limit.

Answer 2

Never get a CITI bank card. They block it every 48 hours to prevent fraud, then you must call them to get it reinstated, or wait until they call you at 8 am to ask you the previous 5 purchases that may have been made by yourself or your spouse. If you do not know the answers, card is shut off. Just as they discriminate against military personnel that must move often and will not allow them an active card unless they have proof of residence for the past year.
