Amex security code for mail

The American Express (Amex) security code for mail is typically the 4-digit code printed on the front of the card, above the card number. This code is also known as the "Card Identification Number" (CID) or "Account Number".

Here's how to find the Amex security code for mail:

1. Look for the 4-digit code printed on the front of your American Express card, above the card number.
2. Make sure to write this code on the outside of the envelope or package when sending your Amex card to the bank or other financial institution.

Note: The Amex security code is not the same as the CVV (Card Verification Value) code, which is a 3- or 4-digit code printed on the back of the card. The CVV code is used for online transactions, while the Amex security code is used for mail transactions.

If you're unsure about the Amex security code or have any questions, you can contact American Express customer service for assistance.
