Common problems

Can't log in: Forgotten User ID or no online account

-
Card declined: Limit reached, typo or fraud alert
- Means
- Amex lists the usual reasons as a card at its limit, a hotel or car rental hold, a wrong card number or address, a fraud alert on an unusual purchase, a missed payment, or an expired card.
- First step
- Try the card again or pay another way for now. All steps
-
Large purchase declined: Spending power depends on your history
- Means
- Cards with No Preset Spending Limit still have a flexible limit that changes with your purchase, payment and credit history. Amex may or may not approve spending over a credit card's limit based on your profile.

-
New card not arrived: Card is still in the mail

Can't activate card: Wrong card details during confirmation

- First step
- Confirm the card online with the card number, the 4-digit code on the front and your personal details. All steps
