It took some searching to find directions on how to use an electric orange checking account from ING Direct to pay an online bill. I tested the instructions below using several different accounts.
1. First login to your ing direct account at http://www.ingdirect.com
2. Click on "My Accounts"
3. Write down the number listed under the "Account #" column
4. Combine this number with the Routing Transit Number "031176110", and you should have all the information most credit cards and other online bill services require to pay your bill.
