I'm sorry you're having this issue. Is the CVV number a four digit number? Amex CVV numbers are four digits as opposed to Visa and Mastercard using only three digits. I just bring this up because I've found this is usually the number one issue when I'm dealing with Amex cards.</P> Tue, 29 Nov 2022 16:27:26 GMT HC_Charlie 2022-11-29T16:27:26Z https://community.squareup.com/t5/Payments-Troubleshooting/Amex-manually-enter-card-and-expiration-date/m-p/619596#M33731 <P>Amex manually enter card and expiration date.
