Purchase Protection Services
American Express goes to great lengths to protect your card from fraudulent use. Below are some examples of the ways we protect your card from fraudulent use.
Fraud Protection Guarantee
Our Fraud Protection Guarantee means you won't be held responsible for any fraudulent charges when you use your American Express Card. No fine print, no deductible - just pure protection so you can shop with confidence anywhere, online or off.
Authorized User Verification
When you use your American Express Card at some retail or online stores, you may be asked to provide your billing zip code or "CID" (Card Identification Digits). American Express compares that information with the zip code or CID on file to help confirm that it is you using the Card. This information is for security purposes only. It will not be used for marketing purposes, and is not retained by the merchant.
Monitoring Your Account for Suspicious Transactions
American Express has sophisticated monitoring systems and controls in place to detect fraudulent activity and protect our Cardmembers' accounts from misuse.
Irregular Account Activity Alert
If we detect a questionable transaction on your account, we will contact you to verify its legitimacy.
Account Alerts
Stay in control of your accounts with Account Alert e-mails or text messages. You can sign up to receive e-mails or text messages to notify you when your payment is due, when your payment is received, when you are approaching your credit/spending limit, and to inform you of your current balance.
Contact Us
If you think you may be a victim of fraud, contact the phone number on the back of your Card or you can find other phone numbers in the "contact us" section of our website.
