Online Services User ID and Password
When registering for Online Services, you will be asked to set up a User ID and Password. You will need these to log in to Online Services via desktop or the Amex App.
If you forget your User ID or Password, you can reset them online by clicking ‘Forgot User ID or Password’ on the login page. You’ll be asked to remember your answer to the Security Validation Question we asked you when you signed up.
Your Customer password is a 4-digit code used to identify you when you call Customer Services and also to view your PIN online through Online Services.
You can set up your Customer password when you activate your Card online by choosing from four options: Mother’s birthday (DD/MM), Father’s birthday (DD/MM), numeric password (4 digits) or memorable date (DD/MM).
To reset your Customer password, please call Customer Services using the number on the back of your Card.
Card Identification number (CID)
Your 4-digit Card Identification number (CID) is an added security feature to help protect you against fraud. Your CID can be found on the front of your Card, above the 15 digit Card number on the right, and printed flat (unlike the Card number). You will be asked to enter this number when viewing your PIN online through Online Services and you may also be asked for this number during phone and online Card transactions.
