Find Your Customer ID

Learn how to find your Customer ID if you don't remember it.

Check for your Customer ID within a order confirmation mailing from 1&1. Since you have an account with 1&1, you should at least have 1 mailing, which would be the order confirmation mailing or a welcome mailing. You can try searching your inbox for "1&1 Internet".
