How to Enroll Amex & Discover for Additional Coverage

To expand your coverage for American Express (AmEx) and Discover chargeback alerts, gather the following information:

To be enrolled in American Express alerts, you must have processed at least a single successful American Express transaction on your payment processor within the last 90 days.

Once you’ve collected all of the above information, sign up for expanded AmEx and Discover coverage with the button below:

Ethoca can't map AmEx numbers retrieved from most payment processors because many payment processors share a single AmEx Merchant ID with many accounts to save costs.

In this case, the only way to retrieve your AmEx SE Number is to get it directly from American Express. To get your SE Number, you must have at least one American Express transaction.

If you have more than one 'Establishment', AmEx may assign more than one SE Number. In this context, AmEx refers to 'Establishments' as each of your websites and all other points of sale.

Here's a link to AmEx's contact page.

Reach out to your payment processor with the following message:

I'm enrolling for Discover Ethoca Alerts and RDR Alerts through my third-party vendor, Chargeback.io. To complete this process, I need my Discover SE number.

​Additionally, I need a full list of my historical billing descriptors and BIN/CAIDs. Could you please provide this information as soon as possible? Let me know if you need anything else from me. I appreciate your help!
