Bump here.
My small story about amex corp card and MR points.
I have been holding AMEX corporate Green card issued from my company since 2020. I just got the renewal card last week.
One thing I noticed is the old card and new card have same card number.
(Cvv and 4 digit pin are different)
On old card name etc was embossed, new card it is printed.
I hadn't enrolled for MR points still now. Just explored it and found that our company offers enrollment to membership rewards program as complimentary to all card holders. But I needed to call cust care and enroll for it.
Called cc and enrolled for it. Basically I wasted last 5 years MR points.
I don't have any other personal amex cards yet.
Attached photo of old and new cards. Design wise I liked the new one.
