Do charges to an American Express card count towards building credit history?
You will notice, too, that even though an Amex card theoretically does not have a stated credit limit, they will decline charges according to their own criteria. The more you establish a history with Amex, the more they will accept in charges. You can also click on a link at the Amex website to check ahead of time if Amex will approve a charge. And each month Amex will report to the credit agencies your high and low balances and whether you paid on time. All that helps you establish a credit history, without you running the risk of racking up credit card debt.
