The Platinum Card® from American Express reports to the credit bureaus monthly, within days after the end of a cardholder’s monthly billing period. The American Express Platinum card reports the card’s credit limit, account balance, payment history, and more to all three of the major credit bureaus: TransUnion, Equifax, and Experian. American Express may use a specific credit bureau more than another, depending on the applicant’s home state, and other factors.
Once the American Express Platinum card reports your account information to a credit bureau, it may take a few days before the updates appear on your credit report. New American Express Platinum cardholders may not see any new credit account info on their credit report for one or two billing periods after getting a card.

Did we answer your question?
I thought Amex Platinum does not have a credit limit? So, they can’t report that. My AMEX PLATINUM Utilization always says $0, which is good, correct. Even with a high balance, because there is no credit limit, meaning there is no true utilization
I thought there was no “credit limit” on the Platinum, Gold and Green cards. How is this reported if there is no limit?
