I asked my fiancée to add me to his AMEX card ($10k limit, 2% utilization, 2005 open date) as an authorize user (which he did last night) for the credit history because it’s the old reporting credit card he has. Will that make a difference? And, will his payment history (100% on time) on that card increase my current payment history percentage (97% on time overall)?
Backstory: I recently paid off my car (5 year loan). My student loan (opened 2004) was closed and moved to another lender so my entire credit history and longest reporting account was whipped out in the blink of an eye. My credit length looks like it's only reporting on open accounts so now I only have about 2 years of a credit file (active/open accounts) since all credit cards I currently have, were obtained within the last 2 years. I closed many of my credit cards in my late 20s when I was trying to pull myself out of debt but I didn't know or realize the credit implications it would have and hindsight, I should have left them open and just not touch them.
Current Score: 
Well heck, that sucks lol thank you for the info.
Welcome to the forums. To elaborate on that, Amex used to backdate all accounts to the year you first popped up in the Amex system, or with an AU card, the year that one was reported as. So say one of our parents opened their account in 1970 and made us an AU at some point. If we opened a new Amex card on January 21st, 2014, it would have been reported with an opening date of January 21st, 1970. Unfortunately in changing this, they no longer backdate AU accounts whatsoever and they really are the onl;y creditor I know of to have gone to that extreme. If there are any other AU accounts you can be added to, you will inherit the entire credit history of that account.
I appreciate this information. Thank you.
I just spoke with him and he said he has a Citi MasterCard that he can add me too. We’ll give that one a try.
